Re: [digitalradio] Re: Network 105 / Multipsk/ New idea
The idea is not new. Pskmail has all this capability built in natively. Rein PA0R Andy all, If you establish a connection keyboard to keyboard , and do not wish to tie up the frequency, then you could QSY and pick a different mode Well of course that's the beauty of packet, it's a time and frequency sharing mode so there's no problem with an ongoing QSO or many QSOs at once, you are not going to significantly affect channel availability if your FRACK setting is appropriate to the Network. A value of 6 is about right for HF. These days there are no full server bbs to bbs mail transfers so it's a much more friendly experience and there are many QSOs ongoing on Network 105. MultiPSK and MixW both do HF packet very well but there is an alternative which is much easier to interface to other services. AGWPE is a freeware packet engine and provides a tcp/ip bridge. For instance, you can configure AGWPE to run 300 baud AFSK packet on one channel of your sound card and 1200bps AFSK on the other channel. You could run HF packet simultaneously with VHF packet. Using John's excellent BPQ32 software you can run a full node with multiple ports. Have 2 sound cards in your PC? Another 2 channels... one could be ARPS if you wanted. Have a friend running AGWPE? Link your station to his via tcp/ip... How about a WL2K RMS on your VHF side? I run such an RMS which is available thru my HF or VHF port and provides an excellent local WL2K gateway. The WL2K RMS will also directly interface to AGWPE so there is not even a need to run a node if you don't wish to. The power in packet, whether it's HF or VHF is the Network it's connected to. For those wanting to learn more we have a Network 105 yahoo group and we'd be delighted to help you get started. We're also looking for more node stations, particularly in the West, central Canada and DX but all are welcome. http://groups.yahoo.com/group/network105/ 73 Sholto --- In digitalradio@yahoogroups.com, obrienaj wrote: As many people know, I've been trying varying ideas of a way to post information on-line about who is QRV.

True, and I seriously doubt that anyone has bothered to do that. The pskmail client - server communication does this all the time. It looks at the result of the last frames (both S/N and arq result) and decides on the mode to use for the next frame (separately for client and server mode).

Re: [digitalradio] Re: Contestia
I know you've said that pskmail collects data to decide which modes to use. But other than switching modes, and perhaps logging that data locally, it's not telling anyone anything :-) If it could collect the S/N, loss % etc. for a period of time and set of modes, and make it available, that could be very interesting! Pskmail servers might export such statistics (even to non-participants) over HTTP. Not a bad idea, I will see what I can do. Rein
Re: [digitalradio] Re: psk-125r
I agree completely with John here, and I can add that ANY psk mode is unsuitable for EME because of the phase instability of the path. This is also why coherent CW does not work for EME. Rein PA0R Hi Mike, Psk125r (and the other r psk modes for that matter) are simply a standard bpsk mode with the following changes: 1. FEC with a rate of 1/2 which means that we send two bits for every bit of data. This redundancy is what provides most of it's extra robustness but of course at the cost of the effective data speed. So psk125r is about (more on this later) the same typing rate as psk63. 2. Convolutional encoder to spread the bits around so that noise has less effect 3. Soft-decoder which takes into account the phase and amplitude of the signal received to decide if it is a strong 1 or 0 or a weak one. Since we send two bits per data bit, the decoder on the receiver end can than decide which one is of better quality and has more chances to be the real thing rather than noise. 4. MFSK varicode for the simple reason that is has for some patterns of characters about 13% speed gain on the standard psk varicode. So in conclusion you may ask why bother with double the bandwidth (and therefore a 3dB power handicap)? The coding gain from all the above is theoretically 5dB and the tests performed in the lab show that this is pretty right and therefore +5 -3 = +2dB of advantage in white noise conditions. But also (and probably more importantly) the spreading of the bits in time allows for the impact of noise bursts to be reduced since it is less probable to have two noise bursts at exactly the same time for the first bit and it's redundant counterpart which is sent later on. This set of modes was created mainly for ARQ applications like Pskmail and Flarq as we wanted to close a gap between the MFSK/IFSK modes which are robust but slow (while remaining below 500Hz bandwidth) and the psk125,250 and 500 modes which are fast but can be more easily disturbed by QRM and need good s/n ratios. Remembering that for ARQ applications, one bad bit is most likely one bad frame that needs to be retransmitted. Regarding QPSK modes: they have also FEC but the spreading of bit is more limited and the 90 degree instead of 180 degree spreading of the phase changes make it only marginally better than bpsk in my experience. In some cases they can be worse in fact. Now for your third question: I doubt that this would be a good mode for EME due to it's level of sensitivity. I am no expert in EME but the little I know it that you need to have a mode that has a very low minimum s/n as the path losses are very high. The JT65A mode has a minimum s/n of -23dB versus something around -13 or -14dB for psk125r. Even the slowest psk mode that I know of, PSK10AM (in Patrick's Multipsk) has a -19.5 minimum s/n, so still a few dBs below JT65A. If these king of modes had any chance in EME then it would need to be slowed down even further, plus I don't know what the EME path is like regarding phase distortion which is a major negative for these modes since they rely and a phase change to encode a 1 or 0. Hope this helps. Best 73s, John (VK2ETA) --- In digitalradio@yahoogroups.com, Mike Lebo wrote: How does pak-125r work? Does it use the same varicode? Does it have error correcting code like QPSK-125?

Re: [digitalradio] Re: PSK-ROBUST - Path Simulation Results vs field tests
For ARQ there is an additional criterion, viz. the value to look for is the thin border line between 95% and 100% copy. 95% copy is generally not enough for efficient ARQ operation. That is why pskmail does not use S/N levels as the only parameter for switching modes, additionally we use block size adaptation and ARQ success. Using this the MFSK and THOR modes get their fair share of the cake under NVIS conditions. Rein PA0R Gary, Thank you for the feedback. Using ARQ systems like you did we have also noticed that faster PSK modes show better performance as in less repeat request than slower ones. Your first theory is the one we believe is the most likely contributor for the ARQ links in general benefiting from faster psk speed (up to a certain point of course). But like you we are a bit puzzled by the apparent robustness of these modes in NVIS conditions. If you are so inclined, could you please perform a comparison between psk250 and psk250R as available in the beta version 3.20 of Fldigi? The FEC of course reduces the speed by almost half but the error rare (ARQ repeats) appears to be lower than even the half psk speed (i.e. psk250r seems more robust than psk125) as Rein reported in his post on this subject. Another perspective would be appreciated. 73s, John --- In digitalradio@yahoogroups.com, Gary wrote: Your question is one that I have also. In our recent NVIS testing with fldigi/flarq we found BPSK250 provided better throughput than other modes we tested, and most notably MFSK32 which we thought would be our safe, robust mode. This was with a variety of band conditions including strong signal, weak signal, selective fading, lightning QRN, grungy power line noise, and all the normal stuff we experience here in the Midwest. Path distances varied from 40 miles to 150 miles which were the distances we were interested in. There were a couple ideas we kicked around as possible reasons why BPSK250 worked so much better than we expected. One was that when the signal took a hit from something like a lightning burst, BPSK250 recovered and resynchronized very fast. The second was even more speculative in that maybe the higher phase modulation rate (250 times per second) was faster than Doppler path modulation allowing the BPSK decoder to ride through. Anyway, we expected BPSK250 to be useless on NVIS but every time we have tried it, it has worked. (and better than most modes.) Maybe there is something that the path simulators are missing. Dunno...

Re: [digitalradio] Re: PSK-ROBUST - Path Simulation Results vs field tests
I have done several tests with DA5UWG on 80m, and the 200 km path still shows lots of multipath. Both antennas are low (mine is a full wave 80m loop at 10m, DA5UWG has a dipole at 12m). Sometimes the mode goes up to PSK500 for a few frames, but it always switches back to PSK500R, PSK250R or MFSK32. There is also a clear variation pattern involving the time of day. Multipath is heaviest around 17:00 local time. I have found PSK500 or PSK250 to be useable only on single hop (Eindhoven-Stockholm) or groundwave ( 50 km) paths. During such occasions they save a lot of time :) I live near an airport, and when a plane is overhead the download from PI4TUE (20 km) switches from PSK500 to PSK500R. Upload remains PSK500R beacause the high noise level at PI4TUE prevents PSK500. The robust modes are generally better than the raw modes, that is why PSK500 is the only PSK raw mode in the mode table of pskmail. This mode table was established using the trial and error method over several months and paths... 73, Rein PA0R Hi Tony, Thank you for the information. This is the issue with field tests, there are always several variables. I will proceed with some other field tests, trying to eliminate some of the variables. In my case I have an inverted V on 40 and 80M at only 9 meters peak over the ground for the server. So if I use a low dipole for the client next time (2 or 4 meters high) instead of the vertical I assume I should be able to safely eliminate ground waves over that distance (95 miles). Am I correct in my understanding that there is still multipath and therefore selective fading in pure NVIS (no ground wave) conditions? Thanks again, Regards, John --- In digitalradio@yahoogroups.com, Tony wrote: John, The first thing that comes to mind is whether there were any ground wave signals mixing with sky waves during your field tests? It's been shown that NVIS throughput can fail when the sky wave echoes interact with ground waves. The sky waves take more time to arrive at the receiver so you can imagine what the difference in timing does to copy when the two signals interact. This is what the NVIS simulations were based on; two channels, one with no delay (simulated ground wave) and the other with a 7 ms delay (simulated NVIS sky wave). January's path tests showed that PSK-R appeared to be less robust than BPSK under NVIS simulation while the white noise tests clearly showed PSK-R the winner in terms of sensitivity. Your field tests seem to reveal the same results in terms of which modes have the edge in sensitivity, but not necessarily the edge in terms of dealing with multi-path timing delays. I could be wrong though and there may have been strong evidence of ground wave interaction? It can be difficult to tell; some paths are more obvious than others.

My tests simply revolve around examining the bahaviour of the Pskmail server adapting speed to the conditions. We have in the latest version a table of modes that the server can use by shifting up and down, one mode at a time. It does so by relying on the s/n report gathered from Fldigi and the number of repeats due to damaged ARQ frames.

This week I did some tests at 95 miles in a strait line from my server on 40 and 80M between about 1PM to 2PM local time so obviously in NVIS conditions. What I noticed every time I would connect in MFSK16, the server would progressively shift the TX mode up into the PSKR modes, up to PSK500R, but never to PSK500. I also noticed that there would be no fallback from PSK250R to MFSK32 after a shift up from MFSK32. So my interpretion is the following: If the PSKR modes had a weakness in NVIS conditions, I would see the server moving continuously between MFSK32 and PSK250R: good reception in MFSK32, speed up to PSK250R, poor reception, return to MFSK32, etc... Also since it did not go up pass PSK500R to PSK500 it indicates that in these particular cases the PSK500R modes was starting to show signs of limitations and the server calculated that there was not enough s/n margin to shift the

The bandwidth includes a certain guard band(minimum distance between 2 different signals), which for JT65 is quite small ... but the time is a large factor... To give a small example: Pskmail using PSK500 ARQ has a spectrum efficiency of 23/500 = 0.046 CPS/Hz ... measured on 14094.0 kHz running 100 mW connected to SM0RWO (1000Miles) ... The longest message in JT65 is 13 characters... and a message takes 48 seconds.. the bandwidth (according to the mode description) is 65 * 2.7 = 175 Hz ...which calculates to (13/48) / 175 = 0.001547619 CPS/Hz I would say this is a pretty bad value... :) Rein PA0R Bill N9DSJ decoded two stations within 24 Hz of each other, how is that for spectrum efficiency?

Re: [digitalradio] Another plug for JT65A ... the spectrum efficient mode
Hi Andy, well, I don't agree... as soon as you talk efficiency, you have to define what that means. For me bandwidth efficiency is 3-dimensional, it defines how much information can be transferred within a certain time span, within a certain bandwidth. JT65A works with 65 frequencies, which are 2.7 Hz apart. So its bandwidth is 175, add to that 2 guard bands if you want to put a different mode close to it on both sides... You can put 2 JT65A signals very close together, because it uses a pseudo-random algorithm to make sure 2 JT65A signals (almost) never use the same concrete frequency at a certain point in time. As such it is quite bandwidth efficient. That changes completely when you would put a PSK signal that close, it would not work anymore. BTW, the comparison I showed was real... PSK500 has a raw speed of 48 CPS, and the net ARQ speed, including arq repeats is 23 CPS. Of course I cannot do it with 100 mW / 1000 Miles all the time, I need 5 Watts for an average connection. On 80m I have a stable connection to DA5UWG during daylight time using PSK500(down)/PSK500R(up). During the night I need MFSK32(down)/THOR8(up) for the same path... Nice thing abt PSkmail 1.0 is that you can start the connect in MFSK16, the system will decide to upgrade the speed/mode when possible, so you work in the most efficient mode most of the time. And BTW, it helps to use modes close to 500Hz bandwidth (PSK500, MFSK32, THOR22) when you use a 500 Hz (matched) filter :) Just wanted to express that looking at problems 1-dimensionally hardly ever reveals the full truth... 73, Rein PA0R Good point.

Using 5 watts for a 300-400 miles trasmission on 80M at night , PSK250 may have needed sveral repeats to send 13 chracters . So even in term so time PSK250 may have been close to 0.001547619 .

Re: [digitalradio] Re: Net14 + PSK-63

This is all you need to send and receive APRS text messages but it can be fun to use an APRS client such as APRSISCE (obtainable froim this Yahoo group: http://groups.yahoo.com/group/aprsisce) so you can see on a map the position of stations whose packets you receive. APRS over PSK63 on 30m is operated using USB with a dial frequency of 10.137600 MHz and an audio frequency of 2100Hz (the latter is an option selected within the APRS Messenger software.) You cannot use a regular PSK63 program to participate in this because the APRS over PSK63 protocol uses checksumming to ensure the validity of packets. There are probably a lot of other questions which have already been answered (or can be asked) in the aforementioned Yahoo groups. This is a very interesting use of PSK63 which appears to provide a more robust method of sending APRS over HF than using 300baud packet.

Re: [digitalradio] Scanning PSKmail WARC freqs
The PSkmail servers only use CALL de CALL when confirming messages or user beaons... If you have captured PSK250 then it will probably have been US servers, or Intermar maritime servers on 10148.0 (center freq) (DK4XI-30), as on 10147.0 we use PSK500R as default. As soon as a connection is established, RSID is only used for the mode change protocol, and a lot of users don't use the software supporting the new protocol yet... Rein PA0R Rein et al. I scanned 10147 and 18105 today for six hours, alternating every 90 seconds with a 3 Khz range. I only picked up three PSk250 RS IDs on 30M and NONE on 17M. Each RS ID on 30M was not decoded well enough to produce a callsign. Since Muktipsk looks for a de ** string, perhaps the stations were sending PSKMAIL IDs without a de ? For the last hour , I listening for 30 minutes on each frequency, listened with my own ears. I heard no PSK250 on 18105 . On 30M I heard two RS IDs and several PSK250 signals without RS ID. perhaps not all PSK mail servers are using RS ID yet ? Andy K3UK

Re: [digitalradio] pskmail help!
You won't get far with PSK500, as most US servers listen on PSK250 as default. You could try the pskmail mailing lists where the server sysops hang out..: http://www.freelists.org/archive/pskmail You may end up organizing your own server that is how we did it in Europe... For frequencies see: http://pskmail.wikispaces.com/PSKmailservers there you see the servers are either on PSK250 or on THOR22.. 73, Rein PA0R Ok guys I'm on 10147.00 usb D with the 746pro sending pings...in psk500 mode from western montana.

Re: [digitalradio] pskmail help!
It depends, if the server has RxID on the mode does not have to be specific, unless the RSID twiddle is too weak for the server to react. Also think about using a slower mode until you are connected... I often use MFSK16 to connect, with PSK500 on the download link (PSK250 in US). MFSK16 is a lot more sensitive than PSK250... Ping uses short frames, which have the best chance of getting through... It shows you if a server can hear you. It also depends if the server has been upgraded to version 1.0.0, older versions did not support multimode properly, they are fixed on PSK250. So, get in touch with the sysops! 73, Rein PA0R Ok, thank I'll chane it to 250If I ping at 500 and the servers are on 250 will they come back to me or do I have to be in mode specific? thanks, Alan http://www.obriensweb.com/digispotter.html Chat, Skeds, and spots all in one (resize to suit)Yahoo!

Re: [digitalradio] Re: Performance of modes: weak sign al and poor ionospheric conditions
What I don't understand is why NOBODY uses the pskmail arq chat mode, which adds an ARQ layer to modes like PSK250R, THOR22 or MFSK32. Why accept 5% error when you can have it 100% error free? Are you afraid your typing errors get to the other end undamaged? Rein PA0R MFSK16 always seems to come up near or at the top of the simulated tests but I can't duplicate that in the real world. My experience is that Olivia 8/500 does as well if not better and gives MUCH greater latitude in tuning while still providing 100% copy under moderate to poor conditions. Olivia 16/500 is much slower but goes way into the noise where I've had terrible results with MFSK16 under the same conditions. And if 8/250 Olivia (slower yet) doesn't do it, I just turn off the HF rig. BTW, my experience is almost all on 80m with NVIS antennae. -Dave, KB3FXI --- In digitalradio@yahoogroups.com, Wes Cosand wes.cos...@... wrote: I have finished a series of simulations looking at the performance of several modes that seemed appropriate for extended keyboard to keyboard rag chew QSOs. I was looking at modes that offered a throughput of about 40 wpm so they could keep up with a reasonable typist with a bandwidth of no more than 500 hz. I used PathSim to measure accuracy of text transmission under white noise and CCIR 520-2 Poor simulated propagation conditions. I measured text accuracy over at least seven minutes of text for each data point. The graph can be found at http://mysite.verizon.net/wz7i/modeimages/Digital%20Modes%20Poor%20Condx.png The methodology, including software packaged used, is outlined at http://mysite.verizon.net/wz7i/digitalmodes.html Summarizing, I arrived at the following SNR (db) for a character error rate of 5%: AWGN Poor DonimnoEX8 -15.3 -3.1 MFSK16 -14.7 -8.5 PSK31 -13.2 -0.8 Contestia500/16 -14.0 -9.2 RTTY -9.1 +3.7 I probably need to look at Olivia 500/4 These data confirm my prejudice about the excellent performance of MFSK16. With the extended low tones implemented in several packages, the mode is not difficult to tune. A couple things surprised me. I would have expected DominoEX to do better under poor propagation. Another surprise is the difference in performance between different software implementations of a given mode. A software program may have excellent decoding performance with one mode and then have performance with another that is not competitive. The above numerical data would vary a good deal if different decoding software were used. So if you find operating with a given mode frustrating, don't discard it without trying another program. I hope that with RSID some of these excellent modes will find greater use. The web site may well have errors so if you find something surprising, please let me know so I can check things.

Re: [digitalradio] IZ8BLY's PSK63F
The worst case and I see this once, transmission is not possible in BPSK (or only at very high speeds as 125 bauds or more). Why not bite the bullet and use PSK125R and pskmail client-to-client arq. It adds an interleaver, is less susceptible to doppler effects and adds full duplex arq at more than PSK31 typing speed and 125 Hz bandwidth. It takes the guessing out of received text and you only type everything 1x... ( NO macros with NAME NAME NAME RST RST RST QTH QTH). It is also a better match for your CW filter. Drawback: it does tranfer your typos without error. Rein PA0R . Suggested frequencies for calling CQ with experimental digital modes = 3584,10147, 14074 USB on your dial plus 1000Hz on waterfall.

Re: [digitalradio] AFCW and keyed cw programs
Windoze can do it... we use N1MM in the contest with 45 wpm direct keying, without problems on fast machines. Of course cwdaemon for linux is even better... Rein PA0R Hello, Keying directly gives possibility to put a true keyer in parallel to the computerized keying, this to be able to either type letters or key the letters according to the feeling of the day. However, in hard keying , if the speed is not too much fast (=25 wpm), computerized dashes ans dots are OK but the precision of the duration being limited under Windows, very fast keying will be not very good (as far as i know). 73 Patrick Selon DANNY DOUGLAS n...@comcast.net: NO- AFCW is NOT better, and if you use it, half your contacts with tell you they hear some audio getting into your keying. I used it a few times, early on, and that is the results. Remember, you also will be using SSB, versus continus wave keying signals, and thus outputting less RF signal. Stay away from it, if at all possible. I hadnt gotten that far with FLDIGI, but if it uses only AFCW, Im gone.

Re: [digitalradio] Ham HF networking digital communication systems
From our mobile phone, we can instantly call a friend on their mobile phone in a distant part of the world, and it will ring... Can you do the same thing with your ham radio? You will find this function in pskmail... Just link passively to any pskmail server on HF, and send an IM via APRS to any other station linked to any other pskmail server, whichever frquency. This also works cross band between HF and VHF/UHF... as well as between HF and an Internet web page. No need to have an active session for this, This works with any mode from THOR8 to PSK500.. No need for sounding, routing is automatic, 73, Rein PA0R -- http://pa0r.blogspirit.com Suggested frequencies for calling CQ with experimental digital modes = 3584,10147, 14074 USB on your dial plus 1000Hz on waterfall.

Re: [digitalradio] HF PBBS Mail - ECOMM Alternative?
Alternatively you can use a packet BBS through pskmail. A lot of packet BBS'es can be reached via the IGATE network. Using the ~TELNET capability of pskmail you can connect to the IGATE network via HF using e.g. THOR22, MFSK16 or PSK500... Rein PA0R Thanks for the reminder Tony. How do we know who our home BBS is?

PSKMAIL works! Tony K2MO, some 336 miles away, connected to my server on 80M. Signals at my end were S2 to S3 with noise showing at S1 when Tony stopped transmitting. Tony sent two emails using Thor22 and one more after we switched (manually) to MFSK16 due to the band weakening a little. The MFSK16 email is the brief one, below, that Tony sent to this group. I have no true sense of throughput in bytes per minute terms, it was not super fast but Thor22 was probably about the same as I have experienced with WINMOR, quite a few retries. MFSK16 really did well when signals faded and QRM was strong. Slow, but the message made it. So, on a noisy 80M with no-gain antennas and just fairly low power (30-50 watts) we were able to send email. The idea with PSKMAIL is that it is not a keyboard QSO application, but an application that enables you to send and retrieve email without direct access to the Internet. Unlike WINMOR , well maybe that is wrong. I was going to say that unlike Winmor it can allow the user to select fast or slow modes with varying performance characteristics to match the conditions. Some might argue that WINMOR and PACTOR do this to a degree , but PSKMAIL with FLDIGI may give you more weapons to select. As an old fashioned ham, I am biased in favour of the use of HF for communications. That bias has led me to want some system for HF emergency communications, something that does not need repeaters or the Internet. I think the variety of applications that have have available now are already well suited for HF emcomms. FLDIGI/FLARQ for peer to peer error free communications. PSKMAIL with FLDIGI for email via many modes, ALE with Email and SMS text message capability in Multipsk and PC-ALE, and WINMOR with eventual HF mailboxes. So, I think now that we have the apps we need. PSKMAIL, WINMOR and others are refining and improving. It should mean more fun for us experimenters ! When we tire of that Skip will point out that there is more experimenting to be done on VHF and faster data transfers with the same software!

Re: [digitalradio] Re: Puppy Mail
There is a new CD image, now including fldigi-3.13, which features
background processing for RSIDrx.
The image you need for the server is pskmail_server-0.9.22b.iso.
It is available from
http://sharon.esrac.ele.tue.nl/pub/linux/ham/pskmail/liveCDs
The puppy-4.1.2 image does not contain the server, and is old.
Just boot from the CD, get a network connection, set up flidigi,
run fldigi and run pskmail_server from a console.
Don't forget to switch RSIDrx ON onm fldigi, your server will then
work in ANY available mode
Support is via the pskmail mailing list

Betreff: [digitalradio] Re: Puppy Mail
burn another CD Russell, perhaps you have a bad burn.
If you have a good burn, you simply load the CD from a system -reboot and
then Puppy will begin to load. It will set up basic drivers (mouse,
keyboard, video card, etc) automatically. It will give you a choice of
display resolution to use (I just opt for the default) and the language. I
choose US English despite it not being real English :)
As you are probably aware from your other server install, the software uses
the Internet to connect to a APRS server in the Nederlands. So you would
need to activate the network/internet settings on the Puppy. That is fairly
easy to do. With FLdigi you will also have to set it up for your sound
devices. The Puppy should detect them for you and display them in the fldigi
configure soundcard area. If it does not, you would need to run the
soundcard setup from the Puppy, that is fairly easy to do too.

Re: [digitalradio] PSKmail Server What mode ? (Tony)
'QSY' traffic is used on some servers to use a separate frequency for arq traffic. On receipt of the QSY command the server will jump to that frequency. Mode will not switch. There are 3 ways to switch modes: * By using RSIDtx on the client and RSIDrx on the server... The server needs fldigi-3.13 for that which has not yet been released. On earlier fldigi versions RSIDrx will work only once on the server. * By choosing the right minuteto connect a scanning server Some servers scan different frequencies/modes. Scan period is 5 minutes, so minutes are 0,1,2,3 and 4. See http://pskmail.wikispaces.com/PSKmailservers for the schedule * By switching modes on- the-fly during a connected session. Just hit the mode you want in the Modes menu., and the client will send a mode switch command to the server. The server will acknowledge the command and switch to the other mode. Modes available on client jpskmail 3.8 beta are THOR8, THOR11, THOR16, THOR22,, MFSK16, MFSK32, BPSK63, BPSK125, BPSK250 (default).

Re: [digitalradio] Re: How does one get started with pskmail?
Then, you need to decide which PSKMAIL SERVER you think will be best for the current conditions, there is a list of servers on their Wiki. Place the callsign of the server on the configure area where you placed your callsign. You can ping on the frequency to hear which servers are available. Like every web page the actual list of servers can be downloaded with the client. Actually, the client automatically draws a list of servers which hear you. Every time you send a position beacon, the servers hearing you without error will send a QSL. As the APRS posit beacon is quite long, you can be sure the servers QSL'ing can hear you reasonably well. After you are configured, with rig on, FLDIGI booted and with the correct mode selected (usually PSK250) you click on the CONNECT button in jPSKMAIL and your rig will transmit a short burst of PSK250. If you are detected by the server, it will answer you. If you here the answer well enough, you will see the word CONNECTED. It is once connected that you can do most things, about the only thing you can do without being conncted is send a ping or report your postion APRS-style. There are a lot more goodies Pskmail is fully APRS compatible, and that works without being connected. You can send messages to other pskmail stations just by saying 'K3UK This is a message ENTER The client will send this message and every server hearing it will transfer it to the APRS backbone on the internet. So wherever K3UK is listening, VHF, HF or internet (XASTIR), the message will be delivered. On HF only the server you are linked to will deliver the message, so preventing chaos. Findu.com has a web page allowing sending messages from internet to APRS, this works as well, and you will receive the message from the server you are linked to. It is also easy to send a short email from pskmail without being connected: Just write 'em...@address this is another message ENTER' no need to be connected, every server picking this up will send the message to the internet. You can also send a tweet via twitter to the pskmail twitter channel. Enter your message and push the 'send tweet' button from the Twitter menu. Again, no need to connect... For all unconnected (unproto) traffic, just repeat a few times if no server picks it up Lots of stuff to play with, and it really starts to be fun when there are several servers on a frequency like in EU... 73, Rein PA0R -- http://pa0r.blogspirit.com Announce your digital presence via our Interactive Sked Pages at http://www.obriensweb.com/sked Recommended digital mode software: Winwarbler, FLDIGI, DM780, or Multipsk Logging Software: DXKeeper or Ham Radio Deluxe.

Re: [digitalradio] jPSKMAIL update record
I attempted to use jPSKMAIl today for first time in a long time. I was able to easily connect to WB5CON tonight and received a message several times that said Hi K3UK, pse update your record I updated my record by connecting and then configuring mail server settings in jPSKMAIL. I clicked on update settings , received a few bits of info from WB5CON but nothing seemed to happen and the update the record message was sent by WB5CON a few more times. How do I update the record correctly? Also, I understand that WB5CON (or other servers) need my outgoing SMTP but I do not see a place with jPSKMAIL to insert that. I see a place for host , reply address, and password but no SMTP. In the edit-preferences-email settings menu you can enter the data for your mail account. For pop (mail download) the server needs pop server, userid and password. For outgoing mail the smtp server needs your reply address. Update by connecting the server and hitting the 'update server' button. The server will reply with 'updated record for CALL'. Data record sent to the server is not readable. If the record is valid next connect the server will not ask again for your record. It checks the validity of the pop data by performing a 'new mail' check on connect. If that fails (e.g. if you did not enable pop on your gmail accont) it will nag you again next time. 73, Rein PA0R -- http://pa0r.blogspirit.com Announce your digital presence via our Interactive Sked Pages at http://www.obriensweb.com/sked Recommended digital mode software: Winwarbler, FLDIGI, DM780, or Multipsk Logging Software: DXKeeper or Ham Radio Deluxe.

Re: [digitalradio] PSKMAIL does NOT need a BBS
Correct for the jpskmail client, it is possible on the old Linux client (version 1.1). I built peer-to-peer operation into the client on request of the NBEMS guys, but they lost interest in pskmail so I stopped putting effort into that. You will see that TTY is greyed out in the Mode menu. THOR22 is a perfect mode for keyboard-to-keyboard operation, you don't normally need ARQ for that. If there is a lot of interest from users I might also build TTY and p-to-p file transfer into the java client. Most ops use jpskmail for messaging, email, web access and HF APRS messaging and downloading WX charts while mobile. 73, Rein PA0R Perhaps I used the wrong term Rein, I meant mail server .

It is very slow but the ops use cw short hand lingo to go faster. They seem to like it because it has FEC by default and is a narrow band mode about the same as CW. It is very good at very weak signals and a lot of noise. The program I use (Fldigi)has many speeds for THOR (4,5,8,11,16,22) so you can go faster if the band gets better. I think this mode is going to start to be a popular mode for weak signal work. The guy I qso'd with uses it to contact Europe at times like now during low sunspot activity.

Re: [digitalradio] Compressing Data
PSKmail uses normal zip compression and B64 encoding. On small files with english text the compression reached by using varicode alone is better. That is why I abandoned compression for email text.

Nevertheless, I expect that in most cases compression will result in a speed-up.

Re: [digitalradio] Re: Time to start a PSK qrp freq?
No AGC means all stages in the chain (including the first mixer) have to cope with a dynamic range of 130 dB (in a proper receiver). The only remedy is proper filtering as early in the chain as possible, with a carefully designed AGC system.. Some 25 years ago Ulrich Rohde has writtien some interesting articles about how to design a receiver, which are still valid. 73, Rein PA0R -Ursprüngliche Nachricht- Von: kh6ty kh...@comcast.net Gesendet: 16.06.09 16:28:57 An: digitalradio@yahoogroups.com Betreff: Re: [digitalradio] Re: Time to start a PSK qrp freq? Frank, often the loss of a weak signal in the presence of a strong one is due to AGC capture by the strong station, which reduces the gain you need for the weak one. Try using passband tuning or IF shift to reduce the presence of the strong station in the passband so the AGC will not be affected by it so much. If you see the waterfall suddenly grow more dim when a strong station comes one, then you can suspect that the strong station has caused the AGC to reduce gain. On our PSK-20 QRP design (Smallwonderlabs.com), we do not use any AGC but have a wide dynamic range detector and there is never any loss of a weak signal when a strong one comes on, even right adjacent to the weak signal. I wish the transceiver manufacturers would start designing receivers that can dispense with AGC on digital modes without overloading the IF chain. 73, Skip KH6TY frankk2ncc wrote: More an issue for me is losing the other stations from the over-driven signal of a strong one.

Re: [digitalradio] PSKMail Windows server?
I am not completely understanding what you can do with PSKmail such as listing files, etc. Not much happens when I connect but maybe my connection is not good enough? I realize that the Windows version is not fully operational at this time, but it gives you a taste of the system. The latest version 0.3.3 ca already do a lot more... This is from the wiki: Send APRS Posit Send APRS message Send APRS email Send ping Send Link packet to server Receive APRS message Receive short email on APRS Receive weather (or other) bulletins automatically and store them. Set APRS Icon Set APRS Beacon Period (10, 30, 60 mins) Set APRS status message GPS connection (RS232 and USB) ARQ terminal mode: Get your mail from ISP (e.g. gmail) Send mail via ISP List, download and read files on the server (tell the sysop what you need) Telnet to any computer on the internet, e.g. your packet mailbox Get special info depending on your location from the web like: - tide information - List of APRS stations - List of messages on findu - For RV'ers a list of parking lots in a radius of 5 Miles from your location (EU only) - The latest wx bulletin - Grib files for zyGrib - Latest IAC fleetcode file for zyGrib etc, etc, etc... as PKSmail is a free decentralized system the sysops determine what info is available on the servers. You will have to bribe the system operators to get your specific stuff on it. In EU we got this organized so the same info is available on various servers, and is updated several times a day.

Re: [digitalradio] PSKMail Windows server?
Tnx Stelios... that is very good news, I was not aware of the Xvfb server. Some reading necssary. Most pskmail servers are indeed run headless, and remote controlled via VNC. Once they are running they need no maintenance, and the GUI uses resources which are unnecessary for the function they perform... Tnx again, some more experimenting to do :) Rein PA0R -Ursprüngliche Nachricht- Von: Stelios Bounanos digra...@enotty.net Gesendet: 31.03.09 19:45:04 An: digitalradio@yahoogroups.com CC: Rein Couperus r...@couperus.com Betreff: Re: [digitalradio] PSKMail Windows server?

Ultimate goal is to use a LAMP server without a GUI in future, but fldigi needs the GUI :) Fldigi needs an X11 display (on Linux/FreeBSD), which makes it non-straightforward to use in server mode. But it's possible with a fake X server such as Xvfb. Excerpt from Xvfb(1): Xvfb is an X server that can run on machines with no display hardware and no physical input devices. It emulates a dumb framebuffer using virtual memory. Here's how you'd use it with fldigi: ssh remote-host Xvfb -ac :99 fldigi -display :99 Debian (and I expect Ubuntu as well) has a convenient shell script wrapper for this, xvfb-run: xvfb-run fldigi -display :99 This ssh command runs fldigi on a remote host and also forwards fldigi's xml-rpc port so that you can then control it with fldigi-shell (or other client): ssh -L 7362:localhost:7362 remote-host xvfb-run fldigi -display :99 You could in addition forward port 7322 to tunnel the ARQ connection so that the pskmail server can be run locally. I'm guessing that you manage the remote pskmail server and fldigi using VNC. If that's only because you need to interact with fldigi, you may find that the xml-rpc interface has all you need, and that you can use the above method to simplify the setup somewhat. A headless fldigi can be very useful; for example you could run a fldigi/pskmail server on a Marvell SheevaPlug or a Beagle Board. Take a look at the xml-rpc methods (fldigi --xmlrpc-list) and let us know if there's anything that could be added for pskmail. The main thing that's missing right now is functions to change RTTY and Olivia parameters (I plan to add them RSN), but I don't think pskmail uses these modems. 73, Stelios, M0GLD.

Re: [digitalradio] PSKmail QRG and features/issues
In EU only 500 Hz bandwidth is allowed on 30 meters. I would suggest those interested in pskmail to discuss further on the pskmail list, you are invited to join at http://www.freelists.org/archive/pskmail. The chances you get help there are bigger and to organize the servers all present server ops should be part of the discussion. By the way, you can ask some of the servers to QSY to a traffic frequency if you expect to have a longer session, so the APRS/calling frequency remains clear. It also helps if the servers listen on that frequency during one minute in the cycle, so if you call there at the right point in time you will not disturb the calling/APRS frequency. Not all servers do this yet, as it requires freq. control of the transmitter. All a matter of organization 73, Rein PA0R PS: This mode is only interesting for mobile or emergency stations which lack internet so the activity on the servers will drop quickly :) -Ursprüngliche Nachricht- Von: Rick W mrf...@frontiernet.net Gesendet: 22.03.09 02:59:19 An: digitalradio@yahoogroups.com Betreff: Re: [digitalradio] PSKmail QRG and features/issues My preference would be to follow the band plan. Assuming I understand things correctly, on 30 meters it is intended that modes up to 2700 Hz remain in the 10.140 - 10.150 sub band and all narrow digimodes (500 Hz or less) in the 10.130 - 10.140, with 10.100 - 10.130 for CW. There is no comment on automatic operation on that band. Why not operate on what has been an unused part of the band from about 10.132 - 10.138? Do you hear stations operating in that part in your region? I tune around quite a bit and have found it pretty much dead. As far as busy frequency detection, I suspect that Winlink 2000 may continue with their rather open viewpoint expressed by their administrator that turning off such protection is needed due to malicious activities and because the bands are so busy. But then again maybe they will surprise us. 73, Rick, KV9U kh6ty wrote: Rick wrote: It was very difficult to actually use the frequency due to many other stations transmitting on top of the server and my signals. What! You were on the frequency first and someone transmitted over top of you? Don't they always listen first? ;-) Therefore, we must be very grateful for Rein's decision to stay in the area with the other automatic stations, even if his signal is narrow and could go elsewhere. However, it might be feasible to operate PSKmail in the guardbands between Pactor-3 station assigned frequencies with less QRM. I think that Pactor-3 seldom uses more than 2100 Hz bandwidth, but the channel is 2500 Hz wide. I hope all future mailbox operators will be just as considerate. An automatic station is unable to QSY, even if it could hear that it was interferring with an ongoing QSO, because it is necessary for it to remain on a published frequency in order to be contactable, and besides, there is nobody present at the automatic station in order to shift frequency.

[digitalradio] jpskmail client for windows and linux adds HF APRS and ARQ to Fldigi
Here is a new and very much improved version of the java pskmail client The client was completely rewritten in java in a team effort by SM0RWO and PA0R. PSKmail adds APRS and ARQ capability to Fldigi 3.10, and uses several digital modes depending on band conditions: PSK63, PSK125, PSK250, THOR22, MFSK64. Default mode is PSK250, ARQ mode decreases speed by some 15%. PSKmail uses adaptive block size control to use the channel efficiently. The software is open source. This client has been tested under linux and windows using java 1.6. Almost all the functions available in the original Linux version are now in there. But, just to keep us busy for a while longer a few things are missing: * Compressed transfer of email * reception of AIC Fleet codes (pskmail FEC format) * File upload However, all the rest is in there:. APRS functions (unconnected): Send APRS Posit Send APRS message Send APRS email Send Ping to servers Send Link packet to server Receive APRS message Receive short email on APRS Set APRS Icon Set Beacon Period (10, 30, 60 mins) Set APRS status message GPS connection (RS232 and USB) Show position, course and speed Bulletin receive Receive weather (or other) bulletins automatically and store them. Email and web functions (ARQ connected mode): Upload of user email settings to a server Create new emails and send them List, read and delete emails at your regular email account List, read and delete emails locally at the server List file area on the server Download files from the server to the client Read files on the client Update files on the client (download) Telnet agent to connect to your packet mailbox via HF. Fetch any web page (text only) Fetch packaged information from the web: Nearest Tide Reference Harbors (based on GPS position) Tidal information for your reference harbor List of APRS stations near you List of APRS messages to you (from findu.com) Get parking sites for RV near you (EU only) Get frequency/mode schedule for list of pskmail servers The archive contains a quick start guide/brief manual describing how to operate the client: http://hermes.esrac.ele.tue.nl/pskmail/jPSKmail-0.3-quick-start.pdf Download is now at:: http://hermes.esrac.ele.tue.nl/pskmail/jpskmail_0_3.zip http://sharon.esrac.ele.tue.nl/pub/linux/ham/pskmail/jpskmail_0_3.zip Installation in windows XP: * install fldigi 3.10, get it running (http://www.w1hkj.com) * unzip the pskmail_0_3.zip archive, enter the new directory, double click the program icon (javapskmail.jar). * done. Beta testers are encouraged to report their impressions and suggestions so that we can continue to improve the client.

Re: [digitalradio] jpskmail client for windows and lin ux adds HF APRS and ARQ to Fldigi
You can send a mode command to fldigi from the jpskmail client. - Mode menu. Default is PSK250. Actually, in the original perl client for linux you can ask the server to change the mode once you are connected. This has not yet been implemented in the java client.

Re: [digitalradio] Emcomm Message Notification Routing Networking Re: Push Messages to the Field
I will elaborate on this as soon as a get home from our cqww-cw location, packing now... Rein CT3/PA0R/P, CT9L -Ursprüngliche Nachricht- Von: expeditionradio [EMAIL PROTECTED] Gesendet: 03.12.08 07:21:45 An: digitalradio@yahoogroups.com Betreff: [digitalradio] Emcomm Message Notification Routing Networking Re: Push Messages to the Field Hi John, Thanks very much, for the detailed comments on PSKmail for this type of application. That is the probably the closest I've seen to approaching push message capability. Here's some follow-up questions: How does the mobile operator determine which PSKmail base and frequency to check in to at any particular moment? Is it manually selected by the operator, i.e., does the mobile operator need to keep manually checking if they remain linked-to-base on an ongoing basis? Does the op need to keep finding another base to be linked-to-base with, so that the notification messages get routed properly? What is the fall-back position for the system for notification, in the case that none of the bases show a link-to-base condition when the target mobile op hasn't checked in for a while? Is there a time-out or not-linked indication to the network or mobile op? I'm very interested in the network server side of how this can work smoothly. I think that it is the key to getting the best notification system. It would make sense to join as many ham networks as possible to this, to enable a message to be routed to the target operator by any method they are using. A mutual cooperation between ham networks could be forged, and this could make it a reality. If one dials a telephone number, it isn't necessary to know which telephone provider company that the called party is using. We need to carry this type of universal networking into the ham radio realm. The email address provides universal portability and networking opportunities for hams. Hams could adopt specific email addresses that are used for emcomm purposes, and use email forwarding. This simple feature could be leveraged to provide powerful networking for hams. At least for the HFN system, the high probability of linking on HF has already been achieved through the power of a network of geographically distributed HF base stations running simultaneously on all bands. It has often been pointed out that HF base-to-mobile can be statistically undependable for 24/7 point-to-point communications with a base station, due to the changing ionospheric propagation and channel conditions. However, the statistical probability for successful communications with a mobile goes way up when dynamic linking with any base in a geographically distributed HF network is added. A single ham band may not be open at any given instant between 2 specific stations. In fact, there might not be any HF band open between those 2 specific stations :) But, it is very rare that all HF bands are closed to everywhere. That points to the need to develop a wider, more flexible, network outlook for HF Emcomm systems; one that is not concentrated so much on NVIS or specific regular propagation patterns. The solar flare that happened during the Katrina disaster response certainly taught us how fragile traditional Net-Control-centric state nets can be that rely on 75 meters only. Bonnie VR2/KQ6XA John (VK2ETA) wrote: Bonnie, The way Pskmail addresses the push messages is by using two concepts: 1. A notion of Linked-to-a-base status and 2. a centrally accessible (over the internet) database so that servers can be coordinated and avoid duplication). More details: The clients (mobile units) have to check in by sending a link to base. From there on, the server will push any new APRS messages (without ack) to the client. Of course other message sources could be pushed as well. Announce your digital presence via our Interactive Sked Page at http://www.obriensweb.com/sked Yahoo!

Re: [digitalradio] THOR robustness or lack of thereof
I have tested THOR22 extensively with PSKmail the past weeks, comparing it to PSK250. It has shown that when PSK250 does not work anymore THOR22 is an excellent replacement. The idea is that when the channel goes so bad that arq with PSK250 slows down to a factor of 4 (PSK63 speed) it is better to use THOR22. A slowdown of 4x is reached when on average 50% of the blocks in a frame of 8 are damaged. In practical use on 80 meters NVIS and 30 meters long range (2000 km) the power factor is 8x. I.e. 40 Watts PSK250 = 5 Watts THOR22. Especially when selective QSB hits on 80 meters THOR22 is a winner. On a mediocre channel there is no speed penalty as the arq with PSK250 will slow down tremendously, and THOR22 has the added benefit of being qrm-hardened. As a result of these tests we have some servers (PI4TUE, DA5UWG, SM0RWO) running in dual mode (PSK250/THOR22) see the wiki for schedules 73, Rein PA0R -Ursprüngliche Nachricht- Von: Tony [EMAIL PROTECTED] Gesendet: 13.10.08 22:42:25 An: digitalradio@yahoogroups.com Betreff: Re: [digitalradio] THOR robustness or lack of thereof Rick, On other thing that I can not understand is why THOR's performance proved to be so poor on Tony's tests. Dave points out that this could be a sample rate problem.

Re: [digitalradio] PSKMail2.0 Client and Slackware12.1??
Greetings and thank you.. Cpan came to the rescue as far as getting everything working but I have another problem in that I can't use fldigi3.0 or 3.02 or 3.03 and PSKMail1.0.. What exactly is the problem Hal? What do you mean, 'can't use'? Rather than a long winded detail--two days of trying--can you tell me if you are running from Slackware12.1 KDE or Gnome Desktop?? /or/ are you running from an Xterm?? I don't have either Desktop on the subject machine.. If you are running from Xterm can you quote the exact invocation you use to start the two programs?? I've tried a bazillion combinations to no avail.. BTW.. FLDigi3.0 or 3.02 or 3.03 all work fine by themselves, the npa binaries of 3.02 or 3.03.. KDE and Gnome are just window managers, The X server does the work. It does not matter if you use KDE, ICEWM, Gnome, JWM or whatever window manager, as long as the X server is running and your libraries are loaded. The combination of libraries is tested on Debian based systems (mostly UBUNTU). It is possible that some libs you find in Slack are not compatible. The error messages on the console will tell you. To be able to help you we will need to know the error messages. if there are no error messages it should work.

Re: [digitalradio] VOX not for ARQ modes
There is one exception to the rule. Pskmail arq works perfectly with vox. Just a matter of optimizing the protocol to fit common hardware instead of the reverse... The trick (thanks K9PS) is to send up to 512 bytes of data in a frame and allow some more time for the switchovers. 73, Rein PA0R -Ursprüngliche Nachricht- Von: Jose A.

For a desktop there should still be a chance of adding a serial port PCI card. I have never used the parport for PTT so far, and it seems I never will... USB is adequate for most common PC jobs, but not for interfacing radios without some _special_ interface. And of course, managing RTS seems to be the most adequate way of applying PTT to a radio. All other ways (VOX, CAT, etc) seem to introduce too much latency in an ARQ link. VOX may be OK just for keyboarding, which may be the the solution for most users, but hardly is a one size fits all solution. 73, Jose, CO2JA --- expeditionradio wrote: Peter OZ1PIF/5Q2M wrote: Either you have to add an external USB- RS232 [...] or resort to the VOX solution. Hi Peter, For ARQ or handshaking modes, VOX is simply way too slow. Signalink will not work. Not an option. Let's crunch the numbers: 1. Really fast VOX with 25milliSecond PTT delay. 2. Add 12mSec to 30mSec transmitter 90% power ramp-up. 3. Total delay = 37mSec to 55mSec! Now, let's take a typical example of a slow ARQ or handshaking mode running at 125 baud (symbols/second) It transmits one symbol every 8 milliseconds. In 37mSec, you have missed 4 symbols. In 55mSec, you have missed 7 symbols. Each time you miss some symbols, this creates more errors that need to be corrected somehow. So, each transmission with a VOX system, you create errors... and each ARQ transmission is trying to fix the previous transmission's error, and the previous errors in the transmissions before that... a vicious cycle :) The other issue is VOX release delay. The longer it is, the more the receive decoder will miss symbols. VOX is totally wrong for ARQ modes. I'm surprised that Signalink doesn't offer any RTS keying, it would be so easy to add to their interface. They are really shooting themselves in the foot with their design choice. A lot of hams are buying these Signalink and other VOX interfaces, and they don't realize what they are missing by doing so. Of course, Signalink doesn't tell them, (the truth would be bad for business). 73 Bonnie VR2/KQ6XA Announce your digital presence via our Interactive Sked Page at http://www.obriensweb.com/sked Check our other Yahoo Groups http://groups.yahoo.com/group/dxlist/ http://groups.yahoo.com/group/contesting http://groups.yahoo.com/group/themixwgroup Yahoo!

Re: [digitalradio] Does K2 work OK for wider digital modes?
Rick, the K2 works ok for the wider modes, with the SSB module built in. I have used it e.g. for MT63 2k, and it worked fine. You do need the modification which temperature-compensates the vfo. MFSK16 is no problem with the K2, I have used it succesfully with gMFSK. I bought the FT897D, which has a very precise VCXO later, because it has 6 and 2 meters and 70 cm, so I take only one rig in the camper (more space left for bottles to cool the operator). I can leave that on for month and it will stay within 10 Hz at any temp. 73, Rein EA/PA0R/P -Ursprüngliche Nachricht- Von: digitalradio@yahoogroups.com Gesendet: 13.03.08 00:50:04 An: digitalradio@yahoogroups.com Betreff: [digitalradio] Does K2 work OK for wider digital modes? With some of the recent comments about filtering and the use of the Elecraft K2, I was wondering if these rigs are OK for the wider digital modes that can exceed 2000 Hz. Also, do you find that most rigs with no TCXO (such as the K2), will work OK for the digital modes, including MFSK16 and similar modes that require very close tolerance on frequency stability? This was one of the things that prompted me to buy the ICOM IC-7000 for my wife, since the TCXO is built in and it has something around 0.5 ppm frequency stability. This is better than some other rigs, such as the Ten Tec Argonaut V which has TCXO, but not that that accuracy. I did not find any problem in using it, but I suspect that this mostly becomes an issue if you are in an environment with changing ambient temperatures, such as outside, field day, emergency use, etc. 73, Rick, KV9U Announce your digital presence via our Interactive Sked Page at http://www.obriensweb.com/sked Check our other Yahoo Groups http://groups.yahoo.com/group/dxlist/ http://groups.yahoo.com/group/contesting http://groups.yahoo.com/group/themixwgroup Yahoo!

Re: [digitalradio] 10 Tips for the PSK31 Digital Mode
Enable your RF attenuation and increase the volume. This can help keep a strong signal from wiping out the weaker ones. Attenuation will probably be around 20 dB, but by dropping the noise level, the signal readability may improve. AGC (Automatic Gain Control) does nothing for a weak signal; it only levels the louder ones. This is a fairly stupid advice, and if you follow it you will miss about 50% of the fun. First thing to do of course is make sure THERE ARE NO STRONGER ONES. In the good old days of CW (an ancient digital mode which was heavily used by older generation hams) we used so-called X-tal filters to filter out signals on a different frequency than the one we worked on. This worked perfectly. Since hams started tuning with clicking a mouse instead of turning a frequency dial this became impossible. QSB on a PSK signal can amount to 80 dB, and using (slow) AGC is a must if you want to copy the weak ones. It also helps to pull weak signals out of noise generated in later stages of the RX. Just using an RF attenuator because there is a strong alien signal within your passband is the WRONG weapon against this. Moreover, NO RX IS LINEAR,so it will produce mixing products which will hit your weak signal. if you want to really take advantage of the small bandwidth why add all that bad stuff on the RX side? To make copy more difficult? Come on, with CW there was an operator who did the decoding. You cannot expect a computer to be as efficient as that. So why not help the poor DSP and filter out noise and crap BEFORE it enters your sound card? 73, Rein EA/PA0R/P (sorry to hit on the same nail over and over...) -- http://pa0r.blogspirit.com Announce your digital presence via our Interactive Sked Page at http://www.obriensweb.com/sked Check our other Yahoo Groups http://groups.yahoo.com/group/dxlist/ http://groups.yahoo.com/group/contesting http://groups.yahoo.com/group/themixwgroup Yahoo!

Re: [digitalradio] 10 Tips for the PSK31 Digital Mode
My comments were meant to be a bit provocative I am reacting to this subject now for the umpteenth time, and still people get the advice to use 2.5 kHz bandfilters on a 31 Hz wide signal. That way you will not get optimum performance from your RX. The ONLY point I wanted to make is that if you use a proper filter, matched to the mode, you will have a lot more fun and hear/work many more stations. The tradeoff is that you have to use a round knob instead of a computer mouse to tune the signal. And as this is the digital RADIO group I thought that a warning was appropriate :) Maybe I should advice to reread the articles about proper RX design by Ullrich Rhode in QST, maybe around 1970... that also tells you how large signals in your rx produce mixing products and desensing, and also why a properly designed AGC system will actually work. I am camping in EA at the moment, and 2 times during the day the pskmail servers I use are slowly QSB'ing from S0 - 20 dB to S9. The AGC easily fixes that (300 HZ filter on a FT897D, using PSK250). The APRS backbone on 10.149 kHz which would be fully inside the 2.5 kHz passband would make all operation impossible without a filter... (These guys relay 300 Bd APRS packets from 2meters to HF by the way, and I could read a book in the light of lamp connected to my antenna... :) The 'noise and crap' I was referring to is the stuff your RX adds to the signal by using non-linear circuits, before giving it to your SOUNDCARD DSP. So even if your rig doesn't have one, your computer does... And yes, I have visited several hams who could hear MORE than twice the stations after switching from a 2.5 kHz (panoramic) to 250 Hz filter. To answer some questions from Jose... Yes, I have worked in M/M and M/2 HP environments. Check CT9L, TS7N (2003), 5A7A(2005), ED8A(last November), all top 3 WW operations. For such activities we use K2's most of the time. And bandfilters on every TRX.

If you do that, you will force the weaker signals to be incopiable. From THERE seems to arise your request to have only feeble signals near your passband. A good radio should have a larger dynamic margin, say, 100 dB. AGC should be able to level signals up to 120 dB... if the front end is not overloaded. A polyphase filter RX, using a quadrature sampling detector can achieve that, without AGC at all. It also helps to pull weak signals out of noise generated in later stages of the RX. Just using an RF attenuator because there is a strong alien signal within your passband is the WRONG weapon against this. Not necessarily so. Have you ever operated a multi operator multi transmitter station ? Maybe it looks against common sense, but that way you can achieve that your front end does not get overloaded.

Re: [digitalradio] Re: 10 Tips for the PSK31 Digital Mode
Frank, 500 Hz is already a nice improvement with respect to 2.5 kHz.. While on the subject of filters, my current setup allows me to narrow my SSB signal down to 500 Hz. Maxed out, the pass band is about 2.7 kHz, (3.6 on CW Wide.) I have no optional filters installed, so I've been thinking of adding one or two (I think YK-88CN and YG-455CN). I like the idea of having a narrower VBT of 250 Hz (-6 dB) to 500 Hz (-60 dB) with the YG-455CN filter. BUT, it seems that's for the CW Narrow mode switch position. Will that do anything all all for SSB? It depends... I don't know the 830 well enough to say. Anyway, the trick normally is to TX in SSB mode and RX in CW mode, and compensate any frequency difference with the RIT control or the CAT remote control. Most transceivers have this cross-mode possibility. Some other transceivers have an RTTY mode which can use a narrow filter, although that is mostly limited to min. 500 Hz. And some can receive RTTY but then only send FSK. In this respect the FT897D is ideal, it allows the use of all filters in all modes. (Which should be the normal case really, why should this be limited? It is set by the software anyway...). I have had bad luck at PI4TUE with the IC756 for instance. I bought a CW filter and found out that the set would not work cross-mode, not even from the memory bank! There the saviour was to shift the 'sweet spot' to 1500 Hz and use the internal DSP with 300 Hz BW. This happens inside the AGC loop, so it is o.k. If your set does not offer one of these possibilities and you don't want to consider buying a new radio you could always buy a K2 kit, which is a box containing 1300 parts. It only needs a bit of soldering, and is ideal for all digital modes :) 73, Rein EA/PA0R/P It's a Kenwood hybrid (TS-830S). If a CW Narrow filter isn't going to help my digital modes RX, then is there some other filter I can add that will give the improvement you've stated above? I've heard of a YG-88S, but don't see any mention of it in the manual. Looks like http://www.qth.com/inrad/ has some in stock. Any suggestions?

Re: [digitalradio] Re: Keeping NBEMS in mind
All high-latency modes are unsuitable for ARQ. A persistent misconception is that you would be using signals near the noise level. As I have stated many times, noise is hardly ever the problem unless it is S8. The problem is multi-path causing QSB (up to 80 dB on path we are using) and QRM from other stations firing up their gear on top of your QSO. PSkmail arq takes care of this very well by repeating the stuff that has been unreadable in the qsb. QRN is taken care of by automatically shortening of the packets when the error rate goes up, which decreases the chance of a packet being hit. Again, noise is seldom the problem, we pick a better path if necessary, depending on time of day. Signal levels are normally around S5-S9 here in EU, depending on time/distance. 73, Rein EA/PA0R/P on a campsite in Spain (3 years experience with PSK63ARQ (2005), PSK125ARQ(2006) and PSK250ARQ(2007,2008). -Ursprüngliche Nachricht- Von: digitalradio@yahoogroups.com Gesendet: 02.03.08 18:52:31 An: digitalradio@yahoogroups.com Betreff: Re: [digitalradio] Re: Keeping NBEMS in mind I can see that some digital modes would not work very well for ARQ that is decoded in real time. MT-63 and MFSK16 both have latency due to their design. I am surprised that MFSK16 was considered, but perhaps this was due to being the most narrow mode that also can work very deep into the noise? Olivia is so very slow relative to the bandwidth, that I would not think of it as a good candidate. The one mode that seems to be a ready made mode for this kind of communication is FAE400 since it already is an ARQ mode and is reasonably narrow for its throughput. This is the best mode I have ever used for an ARQ sound card solution, especially considering how narrow it is for the sensitivity and speed. Alternatively, couldn't the ALE400 mode be incorporated into the NBEMS system since it would then become an ARQ mode, although would work differently than FAE400 and perhaps not as fast? One thing I don't follow completely with Skip is the idea that you need all these signals on one waterfall. I would never tune in a signal very far off from my sweet spot on my rig (varies depending upon rig design) and normally want digital modes to be centered on 1500 Hz in order to be able to use the filtering available to me. It can make a big difference in difficult conditions or when very strong signals or splattering signals are close in. If we had an emergency situation, it seems to me that you would not be having multiple streams of different stations sending data. Especially not for e-mail capability. It may be difficult to even find more than one or two stations that you can connect to and who have a computer interfaced with their rig with the NBEMS program suite installed and know how to use it. Once you were able to find someone, you would likely want to work with them (assuming a savvy operator, no different than other modes), and route your traffic in that manner. They could coordinate with others outside the disaster area and have them come up on frequency as needed for relief. One thing that has concerned me here in the U.S., is the near total lack of interest in developing some method of using voice intermixed with text data, the very thing we most need for emergency communications. While we can legally do it under the Part 97 rules on 160 meters and on 6 meters and up, the bandplans do not reflect that. Why do so few support this capability? It is used everyday by the SSTV and hams doing large data transfers of this type. Maybe we could at least use it on VHF? But I have not found a common frequency in the bandplans. As far as the wide bandwidth and faster modes such as RFSM, this could work under some conditions. Tremendously faster than the NBEMS system, although it does not have the fall back to the weaker signals and requires better signals than what is normally required for very weak SSB. Has anyone done any further testing on VHF with RFSM? It is completely legal to do so here in the U.S. on 6 meters and up. As Andy points out, there are times when the ARQ text digital modes don't work at all, but with FAE400 this seems like much less of a problem considering that it may be able to perform better than PSK31 without ARQ. 73, Rick, KV9U Andrew O'Brien wrote: NBEMS is the software package, not an actual mode.

Re: [digitalradio] Re: Keeping NBEMS in mind
I earlier mentioned ARQ in real time, but if you use the programming technique that KN6KB used when he developed SCAMP, (Sound Card Amateur Messaging Protocol), he used RDFT. While this was not practical to decode during each cycle, he was able to work in the background with the past packet that was received and do the necessary processing. In pskmail the receiver tells the sender what to send next. This is necessary to prepend missing blocks to the next frame. This way you can realize a full duplex k-to-k mode. When downloading a file on a good channel you send 8 blocks x 64 = 512 characters in a frame before you listen for the ack. At PSK250 this is faster than reading speed. I have seen some multiipath, especially when I have tested PSK31 on VHF, but much of that was from aircraft. I am not sure how I can discern multipath when on HF. Is there any clue in the waterfall or do you go by the sound? You see it in the phase indicator and in the quality indicator (horizontal bar below the phase indicator). Typically happens when F1 and F2 propagation takes place simultaneously, especially in mountainous areas. At home I live near Eindhoven airport and the airplane echo doppler also happens on 30 meters. You don't see it on the S-meter, but the 2 signals corrupt the phase completely which is visible on the quality indicator. At this moment IS0GRB-3 is still S8 on 10148.25, noise (from switching power supplies in neighbouring campers) is S5, with peaks to S9+10.

Re: [digitalradio] Some thoughts on antenna polarizati on for emergency use
For a 20 Mile path to the server I use 28 MHz ground wave, works with 5 Watts pskmail day and night. That is with PSK 250. The server has a horizontal dipole on the roof of a 65 meters high building. When I am at our contest location in Germany, 100 Miles away, I use 80 meters NVIS with 80 Watts from the camper to my home with a horizontal linear loaded antenna. Also with PSK250. Difficult during the night because of high qrm levels. 73, Rein EA/PA0R/P -via pskmail server PI4TUE - -Ursprüngliche Nachricht- Von: digitalradio@yahoogroups.com Gesendet: 29.02.08 16:30:39 An: digitalradio@yahoogroups.com Betreff: Re: [digitalradio] Some thoughts on antenna polarization for emergency use Thanks for the comments, Ralph, Most of us OT's have known about the cross polarization for decades. But it really does hit home when you try it out for yourself. I had never had both horizontal and vertical antennas available to me at one time as I only had horizontal back in 1964 when I was first on 2 meter AM. Later on I only had vertical. I spent some time searching the web for some solid information on the distance issue. Some practical numbers perhaps? There just does not seem to be that much advantage to horizontal the closer the stations are to each other. Some difference on the over 100 mile paths perhaps, but I wonder how often we will use that long a path on VHF for this kind of work. My recent SSB contact to north of Chicago to a high end weak signal operator to my 50 watts with a 4 element beam at a very good location tells me that this 180 mile path might have even been difficult for digital modes. Lots of very warbly audio and severe QSB making phone contact barely possible. But it would have been most interesting to try digital on that path to get a feel for it. For digital modes I can operate 160 meters up thru 6 meters, but not 2 meters at this time. Perhaps some of you have tried calling CQ on PSK31 or other modes on say, 6 meters? I have done this many times on 50.290, but no luck and have never heard anything either. I have heard some PSK31 on 28.120 but nothing local as it was likely all Es. Using repeaters is absolutely not an option since we are specifically trying to operate without infrastructure and if the repeaters are operational, other communications are likely to be operational as well in an emergency situation that we are preparing for. And with our terrain, 20 miles on VHF FM through a repeater, can be difficult. Our repeater drops out in several directions when you approach that point when operating mobile, even though the repeater location is on a high water tower at about the highest point in the county. We will find out a lot more this spring/summer when we do the 2 meter SSB tests and find out for myself. Maybe I can convince someone to operate VHF digital? We hope to do something with 6 meters too, but Skip recommends 2 meter SSB equipment for NBEMS digital. We will also be trying several HF antennas to compare portable operation. We have mobile HF operation with my wife's vehicle, but you lose ground wave on 75 meters within 10 to 15 miles. Since there is minimal NVIS pattern from a vertical HF antenna, mobile operation does have its downsides for close in work. Much of what hams think is ground wave on HF, can be NVIS. If the FoF2 drops down to 2 MHz at night, I have found it impossible to try and communicate on 80 meters with a station only 20 miles away. And that is using CW! To give you an idea of the problem that an ARES ham faced this summer during the 1000 year flood, he was stationed at a remote location that was well out of range of the repeater. I just measured the distance and it is only like 15 to 18 miles and yet he had no way to hit the repeater from that location, even though he had a very good portable setup. The only way he could contact the DEC to coordinate ARESMAT help was with cellphone. He later admitted that this was a ridiculous situation. I pointed out that if he is serious about an amateur radio solution, he, and others in ARES/RACES, really need to give consideration to getting their General class license and having HF capability and have the equipment and know how to use it. The only other possibility that I can think of is 2 meter SSB phone/digital, but as I have said, no one has tested the efficacy as yet. In terms of the EOC, we have had several Field Day activities at the site and we tried to set up an 80 meter dipole but the building really does not fit that kind of antenna very well and is festooned with many other antennas that we don't want to interfere with. So if we absolutely must set up HF at that location, we can quickly install a sloper dipole. Not pretty as you point out, but will work. An alternative would be to have a VHF ink to a home station that has emergency power. Or
Re: [digitalradio] NBEMS experience today
Most of your questions are answered here: http://pskmail.wikispaces.com/PSK_arq 73, Rein PA0R -Ursprüngliche Nachricht- Von: digitalradio@yahoogroups.com Gesendet: 07.01.08 02:37:18 An: [EMAIL PROTECTED] Betreff: [digitalradio] NBEMS experience today Several of us were around the 10137 frequency earlier today and tried various combinations of modes, including NBEMS. We had at least KH6TY, K3UK, VE5MU, KC7GNM, and WD4KPD. Some attempts at making transfers was done. I sent Skip one of my standard messages which is the Gettysburgh Address. It took about 6 minutes or so to send with its 1419 character length.using the PSK63 speed. I unfortunately did not record this exactly. Not really fast, but we had quite a few repeats due to conditions being marginal. Again, this mode is intended more for VHF, but it does work on HF, even with fairly modest signals. The main thing is that the message was completely accurate at the receiving station, something nearly impossible to do with most of the sound card modes. What we probably should have done is try the same message with FAE 400 mode and compare the throughput under similar conditions. Eventually it sounds like NBEMS may have a chat mode, which I think would be a good thing, but you can easily switch back and forth between the flarq ARQ add-on and the basic VBdigi program. I wonder if it might be possible to eventually add the FAE 400 mode? In fact, later on I was tuning around and VE5MU was down the band calling on FAE 400 and I just sort of set my cursor on the waterfall and I was connected. We had a lengthy chat and if you have used this mode, you know that it is hard to keep up with the throughput with less than 40 wpm keyboard speed:) And that is when conditions are not the best. I am wondering if it might be possible to have this mode eventually available on VBdigi as it clearly is the superior ARQ HF sound card mode at this time. You can use wide FAE for more speed, but it is no where near as sensitive as the 400 Hz narrower mode. And for those of us who really do not want to operate with moderate width modes (under 500 Hz), the 400 Hz wide mode is ideal. The 10130 to 10140 sub bands under the new Region 2 Band Plan recommends no more than 500 Hz bandwidth. Questions about NBEMS: 1. I think I asked something like this before, but bear with me. It seems to be sending several blocks of data because you see the inserted characters that must be a checksum and if the receiving station decodes all correctly it knows that. Is this a CRC kind of check or something similar? 2. Am I correct that it only requests the parts that it can not decode properly? And it does this even though in between blocks are OK and so don't need ARQ? So you can send maybe three or more blocks with the check and if only one is bad it only resends that one? 3. If it needs to repeat one or more blocks, the transmitting station does the repeat, but then continues to send new data as well? Probably to fill a maximum number of bytes per transmission? 4. If you see someone sending the flarq beacon in VBdigit, and their callsign, is that just a general call to anyone? Or is there some way to differentiate who is to get the message? 5. And then when their callsign appears automatically in the flarq program, does that mean they are trying to connect specifically to your callsign, or is your flarq program just responding to any flarq beacon? 6. If it is a general call, how do we know when you receive a message or who it is supposed to go to? 73, Rick, KV9U -- http://pa0r.blogspirit.com Announce your digital presence via our Interactive Sked Page at http://www.obriensweb.com/sked DRCC contest info : http://www.obriensweb.com/drcc.htm Yahoo!

Jack, yes, pskmail will work with PSK31 as well, in fact it will work with any mode that transports the complete set of ASCII characters (I am working on incorporating RTTY as well). But you will find PSK63 almost as good as PSK31, and a bit less sensitive to frequency stability. I am sure any of the server ops will open a PSK63 channel for you if you need it. We can also run modes like DominoEx if you need it. I know what you mean with the PSION, I used a PSION 3a, and I wrote a CW contest keyer and a contest log program for it.

Re: [digitalradio] NBEMS/Flarq Frequencies
Being so close to another net frequency is not going to work unless you provide a proper filter. Using flarq efficiently you need to * use a 500 Hz filter or better * use a distance of 500 Hz. We have tried to put 2 pskmail servers on a 250 Hz distance but they qrm'ed each other in such a way that is was not feasible. We had to increase the distance to 500 Hz. To use a broad filter and let the DSP do the filtering is basically wrong. The AGC will wipe out the flarq signal to the effect that all packets are damaged and no transfer is possible. To take advantage of the small bandwidth of PSK63 you need to have a matched (100 Hz) filter. If you don't have that it makes more sense to increase the speed to PSK250. That has the added advantage of being less frequency-critical. Just some of the experience we gathered with pskmail... 73, Rein PA0R Pronet came on and I was unable to print anything for it, my beacon will be 10.137/1500hz, I have one single short file in the folder for tranfer.

Re: [digitalradio] Re: NBEMS testing
So far I am very impressed with NBEMS's performance..especially considering it was not meant for non-NVIS HF pathsfor non-NVIS HF paths you might consider lowering the FLARQ exponent parameter to 2 or 3it shortens frame length and makes for less re-tries. Don't make the block length less than 16 characters (exp 4) except for situations where you have heavy QRN. The packet overhead is 8 characters, and you will loose tons of speed. We have learned this during 3 years of practise with pskmail. I don't know if Dave implemented the adaptive block length feature, that should settle for the optimum block length for the condx automatically.

Re: [digitalradio] Re: PSKmail
Flarq is based on pskmail but is not completely compatible. If there is enough interest I could think of generating a C++ class for pskmail, that would also make it a bit faster :) Would take some time though. 73, Rein PA0R -Ursprüngliche Nachricht- Von: digitalradio@yahoogroups.com Gesendet: 01.01.08 16:37:57 An: digitalradio@yahoogroups.com Betreff: [digitalradio] Re: PSKmail It would be nice to have the pskmail functionality in a re-usable form. The code is complicated enough to need deep involvement to understand. It's not possible to quick-hack it into C. We need the help of the author ! There is a C implementation of flARQ. It uses gtk UI toolkit and there is a port of gtk to Windows. I already tried to compile it on Windows and connect it to PocketDigi, but there is some work needed, as threading and communication between flARQ and flDigi are not directly portable to Windows. AFAIK pskmail slightly extends protocol, that flARQ implements. 73, Vojtech OK1IAK -- http://pa0r.blogspirit.com Announce your digital presence via our Interactive Sked Page at http://www.obriensweb.com/drsked/drsked.php View the DRCC numbers database at http://groups.yahoo.com/group/digitalradio/database Yahoo!

Re: [digitalradio] PSKmail
Technically not a big deal indeed. But we are still talking about a few months of spare time :) I will think about it. It might even bring some new life to the packet network. Where I live it is a dying sport. Traffic on our local node (PI1EHV) has gone down to some 10% of what it was... 73, Rein PA0R That is what I would like to do - use pskmail as an internet gateway for an AX25 network on VHF with a TNC like my KAM+. Do I understand that this might not be a big deal? If you also wanted to add the afsk modem, perhaps it might be helpful to examine the source code (in C) for Thomas Sailer's soundmodem at http://www.baycom.org/~tom/ham/soundmodem/ ... 73, Howard K5HB -- http://pa0r.blogspirit.com Announce your digital presence via our Interactive Sked Page at http://www.obriensweb.com/drsked/drsked.php View the DRCC numbers database at http://groups.yahoo.com/group/digitalradio/database Yahoo!

Re: [digitalradio] Licensing of Pactor modes - Source code and detailed specifications
There is so much work involved in writing a fool-proof program with a good user interface that having to also write the encoding / decoding interface would make sure projects unfeasible for a single programmer who codes in his spare time. Simon HB9DRV I can second that :) Rein PA0R -- http://pa0r.blogspirit.com Announce your digital presence via our Interactive Sked Page at http://www.obriensweb.com/drsked/drsked.php View the DRCC numbers database at http://groups.yahoo.com/group/digitalradio/database Yahoo!

Re: [digitalradio] PSKmail
If you have a windows XP machine with 512 MB RAM you may want to try the windows version of the pskmail client. The puppy Linux image runs inside windows and is just 256 MB, so it runs entirely in RAM. As it uses QEMU not every soundcard is supported, only the VESA server works. But you don't have to leave windows for it :) Use 1024x768 resolution. The zip file is at http://sharon.esrac.ele.tue.nl/pub/linux/ham/pskmail/windows/ 73 Rein PA0R P.S.: Most servers use PSK250 now. see http://hermes.esrac.ele.tue.nl/maps/pskmailers.php -Ursprüngliche Nachricht- Von: digitalradio@yahoogroups.com Gesendet: 30.12.07 02:12:10 An: digitalradio@yahoogroups.com Betreff: [digitalradio] PSKmail I have discussed my misadventures with PSKmail enough. I wish that I could get it to work with at least one of my computers, one of which runs Kubuntu, but thus far no luck. Same with several others that I have talked to. My attempts to use an emulator and also to use a Virtual Machine approach. I probably have to increase memory in my dual boot Linux Kubuntu 7.10/Windows XP machine to do this. Rein had a nice youtube interview for those who would like to get some background information on PSKmail. But until it can operate under native Windows OS, I just don't see any interest as yet her in the U.S. I don't see current PSK modes competing directly with Pactor modes, even though both are PSK, because all of the sound card PSK modes are single tone. Pactor 2 uses two PSK tones always at 100 baud, but with different modulation. I am not sure why no one has come up with a two tone PSK sound card modem, but if they did, then they could start matching Pactor 2, especially if they had several different speeds or modulation. But like you say, it is completely open source, so over the long term, maybe things will advance to the point that it will be so compelling that you just have to have it:) 73, Rick, KV9U Demetre SV1UY wrote: For PSKmail information you can check http://www.freelists.org/archives/pskmail/ and perhaps it is a good idea if you also register there so you can follow the guys that are involved with it. Per PA0R has done a marvelous job with it and he uses FLDIGI as a modem, but you probably know all this. Per's code is open and anyone can implement it in any operating system, although he has a zip file and you can run PSKmail even in Windows with a Linux emulator, so you do not need to have a dual boot system. You just boot in your Windows OS and then run his Linux emulator as a Windows program where you can run PSKmail. Up to now they use PSK-250 and there are already a few experimental American servers online. This is a freeware soundcard program and I think it has the potential of reaching PACTOR-2 in a few years according to the pace they are going. Don't forget that really it is a one man's job and he gets nothing out of it, so it is marvelous what he has done, and more marvelous that he allows anyone to touch his code. Per PA0R is probably more interested in seen PSKmail progressing than his own personal glory. He is a true Radio Ham. This is unlike other code writers who although they allow everyone to use their program, they keep their code to themselves. Of course it is everyone's right to protect their code and I do not blame anyone here, I am just stating a fact. 73 de Demetre SV1UY -- http://pa0r.blogspirit.com Announce your digital presence via our Interactive Sked Page at http://www.obriensweb.com/drsked/drsked.php View the DRCC numbers database at http://groups.yahoo.com/group/digitalradio/database Yahoo!
