Re: [digitalradio] what's the latest on WINMOR
The quick update is.. latest beta is 0.3.11.0 released this weekend. Program is now much more stable, less Windows related crashes. Connects are easier to establish. Less ping-ponging Thruput under noisy/weak conditions is still so-so Thruput with a good signal and well adjusted audio levels rivals that of Pactor II. RMS servers now about to be activated.

Or , you listen to a guy working a pileup, and each and every QSO he has to give the same info, in the same format etc. etc. He is also givning each and every staiton a 59 or 599 report, even though he had to ask them three times for his signal report, and twice for names and QTH. You know he is just hitting a MACRO . The 100 people sitting by trying to get his attention are all going to get the same info, in their turn. So, it behooves us all to use them properly, and only when needed. Oh - and Yeah, dont come to me with a Macro ON cw AT 40 WPM, if you cant read 40 when I come back to llyou.

Yesterday a Hawaii station was working a steady pile on PSK31 and each time sent his name and also sent his QTH info two times, once when giving the RST and once when signing 73.

[digitalradio] Digital Triple Spotter: PSK REPORTER, Hamspots, K3Uk Sked Page Combined !
While you could simply do it your self, I have greated a webpage that displays Pskreporter, the K3UK Sked Page, and the Hamspots web page all in one. Each frame is resizable to your own needs. This will work best with a large wide screen monitor. The K3UK Sked page will require you to log in, as will Hamspots. Then choose your page of interest, Digitalradio is the one on the K3UK page related to digital mode spots , but there is quite a bit of digital mode activity on the LOTW page. http://www.obriensweb.com/skedpskr4.html With this page, you can keep an eye on the large activity reported by PSKReporter, and chat with people at the same time. It would be nice if people active on PSKreporter would always log on to a chat page so that we could coordinate QSO attempts and other fun things. Perhaps one day PSKreporter will have there own chat window as a companion to the displayed reception reports.Don't forget you can customize PSKreporter to display spots via several intersting methods, my favourite is by grid square. Using that setting, I can see who others in my grid square are hearing (see http://www.obriensweb.com/pskrgrid.html ) It would be nice to be able to do via 2-3 neighbouring squares., PSKreporter reports multiple digital modes, not just PSK. It can be found in DM780, Fldigi, qnd Multipsk. Comments welcome. Andy K3UK

[digitalradio] Success ! Multiband reporting to PSKreporter via Commander and Multipsk
I have successfully devise a method of scanning several bands and reporting what I am hearing to Pskreporter. I use Multipsk linked to Commander. Multipsk is configured to report to PSKreporter (using a new TEST version of Multipsk) and Commander is configured to scan between common digital frequencies on separate bands. Commander can switch between bands at designated intervals. below is an illustration for a 15 minute period switching every 100 seconds between 30 and 20M. http://www.obriensweb.com/mband.jpg Andy K3UK
Re: [digitalradio] RS ID
But I am also surprised at how many do NOT use it. Today I set my rig to switch between 20 and 30 every 40 seconds. I had RS ID on but decoded no one in 4 hours. While there could have been people transmitting just when I changed frequency for 40 seconds, I would have expected someone to be picked up. I am now cheating by using two apps at the same time. Multipsk in Panoramic mode (so I can at least capture more BPSK reception reports) AND Fldigi in standard mode with RS ID on.

[digitalradio] A Tandem Ride: DX780 and Multipsk
A Tandem Ride: DX780 and Multipsk Being the greedy type, I wanted to be able to scan several bands and not only decode multiple PSK31 signal and send to PSKreporter... I wanted to also detect any RS ID and QSY to it. Since the superbrowser or panoramic PSK31 views of DM780 and MUltipsk do not decode anything else in this mode, I have set up BOTH to run at the same time, each receiving frequency information from my TS-2000. I have Multipsk trawling for RS IDs and DM780 in superbroswer mode. Commander controls the rig and QSYs at designated intervals. My digital interface allows me to have two applications under CAT control (Commander and Multipsk share one) . I tried Fldigi but it could not keep up, perhaps a rig polling setting needs adjusting.

Re: [digitalradio] AFCW and keyed cw programs
Am I wrong in thinking that if one uses something like MixW to direct key a rig that has no internal keyer, that you also get some odd results ? In the early days of Mixw I used direct keying with my TS440, not audio CW. It worked but I would get comments from some that suggested my CW had an odd 'swishing sound to it. I do not get that direct keying the TS-2000. Andy K3UK
[digitalradio] Announcing the 2009 Digitalradio Radio Awards
Digital Ham of The Year : Patrick F6CTE. Tremendous innovations is his software Multipsk in the past year. Patrick listens well, he is open to new ideas, and very talented in taking new ideas and making them work. The SDR capabilities already in Multipsk could be the way of the new decade. Best New Software: SDR-Console by Simon Brown HB9DRV. Just arrived in time for a new decade. Has taken SDR software to a new level. Still very early in development and missing some digital mode decoding integration, but what is already there is amazing. Matched with DM780 in 2010 look out. Best Logging Software: DX Keeper by Dave AA6YQ, again ! Biggest Surprise Of The Year: 1. RMS Express. A very nicely designed application with much promise for 2010 in the emcomm world. While Winmor was highly anticipated on 2009, the total RMS Package is the suprise. Combines Telnet and Winmor messaging with a useful mail client. 2. Increase in Olivia activity. Was almost dead but made a comeback in 2009 . 3. Decline of MFSK16, has taken Olivia's place on the digital death bed. 4. A new release of WSJT . Improvements have made my Bozo's Guide obsolete. Organization of the Year: WPA-NBEMS ( http://wpanbems.org/ ) WPA ARES . Via a well structured and polite approach to digital communication for Emcomm, they have succeeded in doing what many thought was impossible moved FM bound voice-repeater anchored RACES/ARES groups in to the modern age. Have also convinced the world that there is more to emcomm than packet! Their weekly digital practice nets are a model for all to follow. Innovators of the Year: Fldigi team: WRAP and FLICS added to FLDIGI/NBEMS have made this package an absolute must for emcomm hams. FLdigi has continued to develop way beyond a mere multimode application. The Picasso Award: Simon Brown HB9DRV . Two year in a row, but this year for SDR-Console stunningly useful AND looks GREAT. Best Digital Mode Website : PSKreporter by Philip Gladstone... Google maps with Grey Line overlay. LOTW and eQSL alerts, view any mode, etc , etc. The most useful website anyone looking for QSOs. Now being served by DM780, Multipsk, and Fldigi. Oddest Mode in 2009: Text messaging in Multipsk . OMG ! Wishes Come True Award: PSKMAIL for Windows. Nice to see Windows PSKMAIL client, a very useful application for emcomm and travelling hams. This was on the list of needs inventing in 2009. Needs Inventing in 2010 1. New codec for FDMDV, still ! 2. Softrock kits that actually exist. 3. Macro Zapper. Built in to all apps, declines to allow use of more than three macros in any one digital QSO! Disables transmit for one hour if you actually use the macro that counts how many DominoEx QSOs you have had on 12 meters! Most Anticipated Event in 2010: 1. Release of revised/upgraded PC-ALE . Some really cool stuff planned for what already is quite a remarkable application.. 2. Non-beta release of JT65-HF by Joe W6CQZ. The alpha-beta versions demonstrated this application to be the easiest way to get on the air with the most robust digital mode. The awards are based on the suggestions of the 3000+ membership of digitalradio and determined by Andy K3UK (because he knows best ). Andy K3UK

[digitalradio] Speed adaptation in pskmail now complete
Some interesting news for the new decade. Please see the message below. Andy K3UK -- Forwarded message -- From: Rein Couperus r...@couperus.com Date: Sun, Jan 3, 2010 at 6:51 AM Subject: [pskmail] Speed adaptation in pskmail now complete To: pskm...@freelists.org The adaptive speed adjustment feature for the pskmail arq system is now ready for use. The components you need for the java client are: jpskmail-0.4.0.2 fldigi-3.13BL The components for the server are: pskmail_server-0.9.30 fldigi-3.13BL **How does it work?** The pskmail adaptive system automatically adjusts its packet length, speed and mode depending on channel conditions. To allow this, the server constantly monitors how successful a transfer is, and adjusts block length and modem speed and mode to the fastest combination the channel will allow, Three speeds/modes are available for each session, 10 mode profiles can be chosen by the client at the the time a session is started. Profiles available are: 9: PSK500-PSK500R-PSK125 (the fastest combination) 8: PSK500R-PSK250R-PSK125R 7: PSK500-MFSK32-PSK125R 6: PSK500-THOR22-PSK125R 5: PSK250-PSK250R-PSK125R 4: PSK250R-MFSK32-PSK125R 3: PSK500R-THOR22-PSK125R 2: PSK250R-PSK125R-PSK125R 1: MFSK32-MFSK16-PSK125R 0: Use server default Fastest net speed attainable by the system is 41 characters/second (mode profile 9), equaling almost 500 wpm.at a maximum bandwidth of 500 Hz. This speed is reached transferring text on a clean channel without qrm/qrn and a reasonable S/N ratio. Under these conditions each frame, consisting of 8 blocks transfers 512 payload bytes, with zlib compression. If binary data is transferred the compression has little effect, and the throughput rate is 50% of this value. (Pskmail is a text transfer system :) Measurements were done with 1 Watt on 18105 kHz, the server is 20km away from my QTH. With this system the pskmail operator has a choice of modes for a variety of channel conditions. A session will now easily survive a series of strong ALE soundings, and even a longer pactor qrm session is no problem anymore. It will just take a little longerBlock payload varies between 16 and 64 bytes. The system uses RSID to switch modes. Actually RSID reception is the weak link in the system, as the modes used are very robust, often more robust than RSID decoding. Especially the new PSKxxxR modes with soft viterbi decoding and interleaver are rock solid. As the US based stations are not allowed to use PSK500, we had to take measures against unwanted RSID switching. The new fldigi code (3.13BL) now includes a table where one can choose which modes are allowed to be switched by RSID, and likewise which modes are allowed to use RSID TX (tnx VK2ETA and W1HKJ). The new server (0.9.30) has a provision which does not allow US calls to use profiles 9, 7 and 6. If such a profile is requested the server will switch to the default profile 5 (PSK250-PSK250R-PSK125R). MARS users can overrule this limitation. In EU we use PSK500R as default listening mode, but you can connect using any mode available in the client. The Intermar (maritime) servers listen in PSK250. It is now also possible to use client-to-client connect for keyboard-to-keyboard chatting with the jpskmail client. This chat feature does NOT include the adaptive speed switching, as there is an operator on both sides, Choosing PSK250R mode will give you PSK63 typing speed. The system is full duplex and will transfer all typos without error Summing it all up, this opens quite some possibilities for experimentation, which is what it is all about anyway, as far as I am concerned. Have fun testing this... 73, Rein PA0R -- http://pa0r.blogspirit.com

Andy K3UK On Sat, Jan 9, 2010 at 3:39 AM, Tony d...@optonline.net wrote: Tony, a comparison of PSK63F to DominoEX 8 and DominoEX4 on your simulator would be very appreciated! Skip Skip, According to PathSim, DominoEX4 seems to have a relatively low tolerance to Doppler spread. As you can see, DominoEX8 and some of the others seem to be the better choice. The question is whether the UHF path will allow you to test these modes since they may be less sensitive compared to DominoEX4. They obviously need to stay well above minimum decode threshold in order to make sure the Doppler effect is causing the throughput loss and not the QSB. I know that can be difficult to accomplish with weak signals. I set the simulator SNR to -3db to keep signals well above minimum SNR for each mode tested. I used a relatively small path delay for the #2 path which will hopefully represent the multipath delay found on VHF/UHF DX. Of course there's a large number of multipath possibilities so you can only expect so much from the path simulator. Path #1Path#2 Doppler Spread: 5Hz Doppler Spread 5Hz Path Delay: 0 Path delay: 0.1ms
[digitalradio] Time for a Digital Skimmer ?
I've been playing around with CW Skimmer , again. I'm 10 days in to my trial. Previously I had tried it and gave up because I was not too impressed with the CW decoding ability compared to that of Multipsk .. This time I have used it a bit more and learned more about how to use it. In combination with the reverse beacon network (http://www.reversebeacon.net/) , plus some useful ways to use it with Spotcollector and an SDR , I'm quite impressed with what can be done. Now I'm thinking maybe its time to develop something like a Digital Skimmer. PSK Reporter, and application specific things like PSK Broadband decoding in Winwarbler, or Superbrowser in DM780, or Panoramic modes in Multipsk , come close ...but not quite. To have an equivalent of CW Skimmer for digital modes , we would need the following... Ability to detect and decode all common digital modes via RS ID Detection over a wide frequency range 10 kHz -200 Khz, multiple bands at same time (with an SDR panadapter). Multipsk can do some of this now. Recognition of any CQ de K3UK type call Placement of any QRL on waterfall or band map Placement of any 5NN or 599 on waterfall or band map Placement of detected callsigns on the waterfall (some apps can do this already) or on a band map Mouse controlled narrowing/widening of the audio frequency range played via PC speakers.

[digitalradio] NEW : Digitalradio 2010 Challenge via Clublogs
I have arranged for clublogs.org (http://www.clublogs.org) to add Digitalradio as a club . This means you can connect to their web site, registered, and then upload your log . The upload will be an ADIF upload. If you need help with that part, just let me know, it is quite easy. You also need to add digitalradio as a club you belong to. To do that click on CLUBS and pick digitalradio from the list. You can add other clubs that you belong to, also.Once you have done that you will be able to participate in a variety of challenges. One will be between members of digitalradio, and an other can be digitalradio versus others groups/clubs. I am particularly interested in a 2010 challenge for data QSOs. Clublogs.org will allow you to filter your log and see QSOs and DXCC entities worked by mode (CW, SSB , or DATA) . So upload your log periodically and see where you stand versus other people and how we stand versus other clubs. After you upload your log and join a club, it can take some time before your data starts to show. Andy K3UK About Club Log Introduction by Michael G7VJR Club Log is a web-based application that uses a large database to analyse amateur radio log files, which are uploaded by users all over the world. Using the logs, it is possible to offer band-mode league tables, efficient log search tools, analysis for DXpedition planning purposes and most wanted lists for DXCC entities (including by date, band or mode for example). There is a great deal of information that can be mined and analysed in a standard ADIF file. Club Log can provide empirical propagation charts, and give back to its users the ability to find wanted DX spots, identify QSLing gaps and perform other analysis of their logs which might be hard to do with normal logging software. Through Club Log, I also host online log search systems for significant DXpeditions. One of the driving principles of Club Log is to store as many QSOs as possible, as this makes the reports and statistics more meaningful and representative. Everything in Club Log depends upon analysing real QSOs, and or this reason I am very grateful to everyone who participates. If you have not joined yet, I warmly invite you to sign up and join the action! It is completely free.

Re: [digitalradio] Which Digi Program ??
I will jump in on this topic.. with the TS-440. Using the TS440, one can use the RCA Phono jacks on the back of the TS440 labelled AFSK In and AFSK out.Then use vox to key the rig via software like DM780 , Fldigi. or Multipsk. Using this method with plain audio cables results in NO isolation between rig and computer and increases the chances of ground loops causing distorted or noisy transmitted tones. If you keep the transmitted power to around 25 watts or less , you can usually get a clean signal. You can use home made circuits to isolate the rig-PC or buy some commercial products usually made for car stereo systems that eliminate ground loops.

Re: [digitalradio] Haiti a test for emcomms
Yes Howard. The HF Ale network is very active with hams standing by but I do not see any actual use of the ALE stations, so far. PSKmail , as I mentioned earlier, appears tailor made for relaying traffic from/to Haiti . from a ham to an ISP server. Winmor/Winlink could also carry traffic from the island and pop in into the Internet. The question is ... will any of these get any actual use, or will hams on the island revert to old tested methods... phone nets and phone patches ?

[digitalradio] ARES Preparedness / No point in ALE without ARES in USA
I'm thinking about the Haiti situation and the use of ALE stations for emcomms. I'm also thinking about ARES and how it handles something like the Haiti earth quake. I was impressed by the turn out of ALE hams on the air in the past couple of days , over 50 stations ready and 'alert. I am perhaps biased , but I think ALE is great for emergency communications. However, I am not sure about the effective use of ALE as it stands today. By default , ALE in North America is connected with HF Link and their fine efforts to deploy a network. Their network has brought several innovative methods to ALE , such as pilot stations , email , and SMS text messages. However, as I watch the ALE network efforts via the HF Link web site, I note the solicitations to stations that may be en route to Haiti to feel free to use HF link and ALE for ecomms. As I thought more about this, I have concluded that since the whole emcomm system in the USA is centered around ARES and RACES (and perhaps a few long established emergency nets) , it seems to me that ALE stations should be part of national and regional ARES and be called out as part of ARES' structure. This would get many more stations to be aware of ALE's effectiveness and integrate ALE in to a system that would see its use, rather than almost beg for stations to use them. My challenge to the ARES/RACES chapters that may read this message is... are you aware that there is a world wide network of highly capable HF systems that can be activated and called out very quickly? Does your chapter have a ALE capable station that can be activated in the event emcomm is needed to and from your area ? Perhaps I would go further and suggest that each ARES group should have not only at least one ALE station , but one PSKmail capable server, one NBEMS station, and one Winlink/Winmor station ( I know my local county does have at least one of each, but I am not sure if my local ARES knows that). Finally, I would also ask did each local ARES chapter in the USA activate or place themselves on alert when the earth quake hit? Before someone says well , we are so far away and were probably not needed, consider the HH2JR request for a phone patch yesterday. If Jean HH2JR had requested the delivery of info to your local ARES area, did your ARES activate and assign people to check in or listen to the nets that ARRL announced? I'm not talking about some friendly ham forwarding email about international net frequencies being left clear, I am talking about a formal alert activation by each local ARES in the event local traffic needed to be handled. Even in my rural area, I received two emails asking for help in finding family in Haiti. Suppose their family had a Haitian ham looking to get a message in to my area (or yours ) ? Just some food for thought... Andy K3Uk

[digitalradio] Digital modes with an SDR ?
My SDR receiver is due to be delivered tomorrow. I am looking forward to using a wide band panadapter for receive and having my transceiver sync'd for ability to transmit when desired. Since I vacillate between CW and digital modes , I will enjoy keeping an eye on both portions of a band at the same time. I am also looking forward to trying Multipsk with is SDR capabilities and RS ID combination. I assume there are many others with SDR transceivers or receivers here in this group, and wonder how you are using it for digital modes ? Andy K3UK
[digitalradio] Initial thoughts on SDR
I have not had an SDR even 24 hours yet, but here are some random initial thoughts. 3 Yrs ago I contemplated a Flex radio and talked to a neighbour who owned one. He loved his, but warned my that they were very much a work in progress and not for someone who wanted a has to do everything box. I decided to put my hard earned cash in to a TS2000 instead. 3 years later, I have an inexpensive SDR receiver . I have concluded that they are still a work in progress, software is still being refined. Many things can't be done easily. However 2010 seems to be the year we can expect MAJOR improvements like Simon's SDR-Radio. While Simon's product is very much a work in progress, it is also a work of art ! Other software appears geeky and will scare people away. Simon's looks like a radio, and will make the rookie more at ease. After 24 hours, almost... I think I will conclude that seeing a whole bunch of spectrum at once is very useful but something you will lose interest in on average ham days, perhaps only when hunting a specific DXpdition will actually WATCHING the PC screen be something you want to do. To really get a lot of joy, you will want software that will do the looking: for you and organize what is heard over several hundred Khz . Luckily this is available via CW Skimmer for the CW fanatic and via Multipsk for the digital enthusiast. I am not sure what you will want for SSB/phone signals.So, in my opinion, if you get a SDR ..figure on also owning CW Skimmer ( $75!) and Multipsk, Dm780 is likely to have significant interfacing with SDRs later in 2010,, Pleasantly, broadcast band Dxing and Utility DXing is a joy with an SDR. I don't think anyone has invented the equivalent of a CW Skimmer or RS ID-type station identification for broadcast bands, but I suspect it could be done if someone thought more about it (a digital ID broadcast by the station that software would pick up and display on a PC screen ? ) Interfacing SDR's with things like clusters and logging software is not as straight forward as it might seem... still refinements needed for this process. Eventually, perhaps now ...already, SDR display screens will be simply bandmaps with station callsigns . The gee-whiz spectrum analyzer type display will be a background item to show off when guests arrive, . Andy K3UK
Re: [digitalradio] Re: Initial thoughts on SDR
Thanks for the comments, everyone. An SDR certainly makes the experience in the shack even better. Steve, I do have VAC on my PC but I have not figured out what it does yet, your comments are interesting. AFter 24 hours, I have used my SDR-IQ with CW Skimmer ( amazing with an SDR) , SDR-Radio, Winrad, and SpectraVuew. I have finally figured out Winrad and SpectraVie, while both appear geeky they do work quite nicely and have useful features. The only thing I have not got running is Multipsk with SDR-Radio, Multipsk with wide panadaper display PLUS SDR-Radio is too much for my PC. I am surprised because I would have thought a P4 with 2.3 CPU and 1 gig of RAM would have been able to run just these two applications. However, SDR-Radio in is technology preview takes about 55% of my CPU even at the lowest display settings and least bandwidth. I assume beta releases will see that improve. Multipsk in is regular use takes about 15% CPU but increases to 30-40% when I activate the SDR features, even with just 44 kHz display . The two combined crawl to a halt. So I need to play around with my PC some more and see if I can dump any loaded background applications. I will also try Multipsk with Spectravue and see what happens...

The 5000A is a one box solution. The SDR-1000, the original Flex model, definitely requires a bunch of boxes and cables. Yes the 5000A and certain options will fix in one box. The exception, of course, is the PC. And I don't feel the need for numerous add-ons and accessories. Yes it is a work in progress. Generally the rig gets better as things progress. It is a much better rig than it was when I first bought it. I have a couple of the ICOM Pro Series rigs, and you are stuck with the rig with the feature set it first came with. The Flex keeps adding new features. I've never had rig before that has satisfied my itch for something different or better. Yes I drool at the thought of getting an Elecraft K3. And there is the constant nagging thought using a rig not tethered to a PC. Yet I continually return the 5000A after a CW stint on my Elecraft K2/100. I can't image anything better than SDR for digital work. VAC (Virtual Audio Cables) really makes the sound card modes shine. VAC eliminates a whole layer of D-A and A-D conversion with a pure digital connection between the rig and a virtual sound card. In fact SDRs can eliminate the interface box when running sound card modes. There are some short comings, such as latency, which comes into play with full QSK CW. Perhaps TOR modes could be affected by latency. I feel that is offset by having the best receiver I've ever owned. In case my, that is mid level rigs, and not the Cadillacs. Sherwood Engineering ranks the 5000A second after the first place Elecraft K3. I am not sure just what Andy's SDR receiver is and how it compares to the Flex series. I definitely would not hesitate to recommend SDRs. My experience is solely Flex based. I can't give an opinion on other SDR solutions as I've not tried them. SDRs require a ham who really likes to tweak and is technically astute. It is not for appliances operators. Somehow I think most members of this group fit that description. 73, Steve N6VL

[digitalradio] Future of ALE and HF Link.
I have decided that I will not be a part of HF Link, in the formal sense. Many members of the Yahoo group HFlink have been helpful over the years and Steve especially has been of tremendous help to all. However, I have concluded that the rigid control and moderation of that group, have contributed to the failure of ALE to take hold as an effective method of amateur radio communication. Despite years of efforts, ALE remains perhaps the least used method of ham radio contact management, and is regularly used by less than 75 hams world-wide. I know of no other amateur radio method that is dependent solely on one group , and that one group has such prohibitive practices that it essentially dictates terms. The copyright policy of the HF Link group is directly contributing to a lack of openness that is rarely seen in the amateur radio world. PSK and digital modes have many organizations and email lists, CW has lots of groups, SSB-phone a zillion clubs, RACES/ARES accepts a wider choices of systems, weak signals modes like JT65A have varying groups, but ALE on hams bands remains centralized via HF link. Winmor has tight control on the software but is generally open to input and openly allows dissent. ALE should be allowed to flourish in an open market where hams take the idea and help it evolve and succeed. Steve and Charles Brain have made huge contributions but the warehousing of it via HF link have reduced it to a little understood concept . I will continue to use ALE both PC-ALE and Multipsk . but no longer associate with HF Link. I have raised this matter before , and have received constructive comments the suggest that the control is to prevent ALE bashing . I think that there is not a lot to bash about ALE...it is a very effective system, However the protectionism exhibited by HF Link has harmed ALE more than the occasional ALE bashing would ever do. So, the problems of busy detect and unattended operation notwithstanding, I will remain an advocate of ALE and hope others will help it get rid of its shackles. Heck , lets get rid of ALE as an emcomm concept , it isn't really (it could be , one day). ALE might be more sellable as a DXing method or net control software! Andy K3UK
[digitalradio] Super narrow filter: PSK31 with HB9DRV SDR-RADIO
Finally! When I bought my TS-2000 a couple of years ago, I was aware of one criticism for the digital operator super narrow filtering in SSB was not as easy to achieve as in other rigs.It can be done via a radio equivalent of standing on your head , using CW to receive and USB to transmit. The steps to achieve that are not easy to automate, so I have found it difficult to cope with those monster nearby PSK signals that swamp the waterfall, and could be eased out if I had better filtering in USB. So, tonight, I decided to see how that would be addressed with my new SDR-IQ receiver and Simon Brown's preview release of SDR-Radio . I was very happy to be easily able to dial in narrow filters, til my heart's content. All at the stroke of a mouse slider, couldn't be simpler. Simon's software is still very early in development , so not yet seamlessly integrated with his DM780. Take a look at this screen shot if you are interested, http://www.obriensweb.com/36hz.jpg I highlighted items of interest in a red ellipse. I used Mixw to decode the PSK31 because SDR-Radio does not do it itself. Yes, I know... Mixw displays 20M, but I was actually on 80M. I have yet to try this when there is a monster signal nearby that needs to be nulled out , but I think the results will be good. Andy K3UK

[digitalradio] SDR-Radio with DM780 20M Digital Band
One of the things that I wanted to accomplish with an SDR receiver, is the ability to keep an eye on the whole 14065 to 14115 frequency range. If I was down on 14074 monitoring ALE 400 traffic, I would miss Olivia signals that popped up in the 14109 area. I would also miss Hell signals at 14068. Now the SDR affords the opportunity to keep an eye all all at once. My venture in to SDR from a digital mode perspective has led to a discovery that, other than Multipsk, the current state of the art does not support direct monitoring of wider I/Q data. I'm also challenged in that my PC cannot cope with the Multipsk CPU demand when I try direct monitoring. So, at the moment I am visually monitoring signals with the SDR and using traditional software methods to decode the 3-4 kHz of audio that is fed from the SDR to applications like DM780 or Fldigi. At this screen shot http://www.obriensweb.com/sdrdm780.jpg you will see how it appears. I am simply using DM780 and SDR-Radio software together. When I need to transmit, I just use my TS2000 after dialing in the signal discovered by the SDR receiver. Simon HB9DRV will likely integrate these two applications later in 2010. I did catch a Russian on RTTY this morning that I would have otherwise missed while I was slumming it in PSK31-land.. Multisk does RS-ID over this entire 14065-14115 portion, and DM780 is likely going to include this ability in the future. If people use RS-ID often enough, it will be really cool to monitor 14065-14115 and get RS ID alerts. So, just over a week playing around with the SDR receiver... I see the potential... digital mode applications are not quite there yet. When they are there (as in Multipsk) my PC isn't. This $41.00 Ebay PC may eventually get retired for a slightly improved one with better CPU. OK, back to keeping an eye on 14065-14115. A-ha, an SV3 calling CQ RTTY, 14082. Andy K3UK
Re: [digitalradio] SDR-Radio with DM780 20M Digital Band
Tony, my shack PC sounds like yours. A Dell P4, 2.3 CPU , but only 1 gig of RAM. Perhaps we can compare current system resource utilization for regular Multipsk ? Regular Multipsk in PSK31 mode with a 4,3 Khz waterfall uses 25 % of CPU. With RS ID on , about the same 25-26% With Panoramic decode.. CPU increases to around 30%. Then Multipsk with Direct I/Q mode invoked , CPU increases to 60% Then RS ID in SDR /IQ direct invoked, Multipsk uses 90% of my CPU. The above is JUST Multipsk related, obviously other applications , like a web browser being open, add more demand. My daughter is away skiing this weekend, so I may borrow her Vista laptop and do a comparison. I do not know what is realistic for Multipsk with all its SDR receive capability and RS ID. I don;t really understand what actual performance increase one could expect if CPU was 3.0 Ghz rather than 2.3, Also not sure what performance improvement going to a dual core around the same clock speed would produce. On my shack PC, Multipsk seems close , I am guessing if I could eek out another 10% it would run just fine. I'm reluctant to put more RAM in to an old machine, but I do have a compatible 1 Gig memory chip that i could pilfer from another PC and see if 2 gigs of RAM ease demand on the CPU. I'm guessing it would not make much difference. I do have plenty of HD space. Hope you and the family are all OK, Andy.

[digitalradio] Understanding Virtual Audio Cable ?
I understand sound cards. For digital modes, we need to know how to set up audio coming in to the soud card and out of the sound card. When there is more than one sound card in the PC, we need to know how to set up digital mode applications for the desired sound card. All relatively easy (except the odd nomenclature in Windows Sound Mixer). A couple of years ago , I was having coffee with a neighbour ham who had a new Flex 100 and he was explaining that digital mode with that radio was a challenge (back then) and that they had to use Virtual Audio Cable. I remember reading something about it, briefly, and then forgetting about it. There is something about the term virtual audio cab;le that causes my mind to melt, I have a hard time grasping what it does. Probably the word cable that is throwing my brain off. The other day, I downloaded Virtual Audio Cable. I took a quick look , got awfully confused, and closed the application. I figure that this weekend, I will open it again and finally try to figure it out. Would I be far off if I guess that VAC essentially creates an audio IN and OUT path similar to having a second sound card? I am not sure that I have any ham radio applications that require VAC, but i figure I better finally learn what it can do. Andy K3UK
[digitalradio] Multipsk- CPU tests with SDR-IQ Direct active.
Interesting data , Tony. I am was surprised that our similar computers have so dissimilar results. So , I checked a few things on different PCs here at my location. Here are my results, The CPU demand is based on maximizing Multipsk's tasks (SDR-Direct active, with full RS-ID on and regular waterfall at 4 Khz) . Casual readers of this thread should note that Multipsk under most common scenarios for ham radio, uses much less CPU than below. Shack Computer (Dell Opitiplex GX260 , 2.3 Ghz CPU single core , 1 gig RAM. Windows XP. Multipsk = 95-100+ % (not usable) Home PC (Dell Optiplex GX270 , 2.7 CPU single core , 512 RAM, WIndows XP. Multipsk = 65% , worked well.) Low end Acer Latop , 3 gig RAM, Windows 7. . Multipsk = 75%, worked fine. Ironic that the one PC I want to get Multipsk to work on is the one PC that it does poorly on ! The good news is that when maximizing Multipsk on a basic PC , with not a lot of other things multi-tasking, Multipsk will work. I am especially pleased to see it work well on the Windows 7 laptop which only cost $247.00 So while the desktop computers do not have identical parameters (different system files, ect) , I am intrigued about the 30-35% less CPU demand on the PC with only 512 RAM but .4 Ghz more processing speed . Does .4 ghz more speed usually make that much difference.. Your outcomes , Tony, also intrige me about what difference I might discover if I add another gig of RAM to my 2.3 CPU ham PC.

Re: [digitalradio] Multipsk- CPU tests with SDR-IQ Direct active.
Well, you can run the SDR part of Multipsk (just press SDR I/Q Direct button in the configuration area, then press RX/TX to return to the main screen. Then you will see the SDR waterfall open up. The problem is that without an SDR, you will only get up to khz of signal, same as the regular waterfall. Som other than testing CPU load, it defeats the purpose. I am guessing you are correct about the dual versus single core. I may try to minimize the other items that my PC boots at start up , but they aree not listed by the Task Manager as taking much CPU.

My goal is also to be able to monitor all the digital portions of the band and to be able to spot all call signs in any mode across the band. CW Skimmer is a good model for that. In addition, it would nice to be able to select a few segments of the band (~5 KHz span in each segment) and to be able to select a few specific signals in each segment for continuous decoding in various modes. As far as I know MixW is the only package that can decode multiple modes simultaneously. PSDR and SDR-Radio allow the selection of multiple segments (2 for PSDR, 3 for SDR-Radio) but the integration with digital mode decoding is not built-in with the SDR software. Ed, thanks. You are way ahead of me on this stuff. I have not tried multiple segments yet, that will be interesting to try. My maximum is 192 Khz at the moment. I expect that I will move to something like an SDR-14 in the future and have 30 Mhz capability at some point. I am glad I did not plonk down a hard earned thousand bucks to find out that the software isn't;really 'ready yet, and that my PC's will need a major upgrade. So, I am happy with the learning curve at the moment and will be better prepared when ready to move up in a serious way. PSK skimmers are essentially already within FLdigi, Multipsk, Winwarbler, and DM780. Broadening PSK callsign mining to four of 5 Khz segments should eventually be possible , and not very taxing. RTTY skimming during a contest might require several 100 kHz segments, that might be tougher than skimming the same bandwidth for CW signals. I suppose the serious digital mode skimmer would want to continually keep an eye on all PSK31 and RTTY signals just like the CW enthusiasts want all CW segments. If there were eventually PSK31 and RTTY skimmers, the remaining Olivia, Hell, MFSK16, and THOR signals would be something most would happily manually watch/listen for. Thanks for sharing your benchmarks. Andy K3UK
Re: [digitalradio] Is there a ham in SW Minneapolis/Bloomington who can help me to go digital?
Hopefully you will here from a local ham. If you do not, I may be able to help, I have some experience in setting up a digikeyey with the Icom 7000 and Icom 746 Pro, I helped a ham in my area get all set for digimodes . I would recommend that you start with the DX Lab suite of applications. I recommend this not only because they are good, but also because the author Dave AA6YQ is very responsive to any needs, and Joe W4TV from Microham USA also works effectively with Dave on such matters. . DX Lab includes Winwabler, this will give you RTTY and PSK only, but that is about 90% of the digital mode activity. If you eventually want to add other more exotic modes, adding Multipsk would be logical because it seamlessly interfaces with the DX Lab applications. The game plan in such matters is to first get the Digikeyer device router installed and talking to the program within DX Lab called Commander. Commander will need to achieve two tasks, read the frequncy from your Icom and toggle your Icom between transmit and receive when desired. If that is achieved, we are pretty much done. Then , when Commander is configured correctly we set-up Winwarbler. Winwarblerd decodes RTTY and PSK. and seamlessly interfaces with Commander. The set-up for someone who knows what they are doing is less than 10 minutes. Macros are fairly simple but take a little time to customize , same with things like color schemes, etc. The souncard issues are taking care of by the Digikeyer because the sounccard is part of the Digikeyer. The set-up key factor is to point to the correct audio codec DX Lab Suite also includes DX Keeper, great logging software. Windows Vista may be the challenge, I have no experience with that, a tiny bit of experience with Windows 7.

[digitalradio] Focus on Hamspots
While the digitalradio sked page will continue, I am switching the primary recommendation for digital mode spotting to Hamspots ( http://www.hamspots.net/). Laurie VK3AMA has provided many innovations to this service in 2009 and plans to add even more in 2010. The Digitalradio tab on the K3UK Sked Page will remain but will likely continue its current role of being more a chat room for people trying to test digital modes. For alerting as to who is QRV and via what mode, Hamspots is better suited, especially now that there is some integration with PSKreporter. While the average PSK31 enthusiasts will almost always find someone to have a QSO with, the original Digitalradio sked page was set-up to help those wanting QSOs on other digital modes, and to avoid the wrath of DX Cluster sysops who wanted only real DX.. Over the years things have become diluted as people use a variety of web sites to announce their presence. It is my opinion that the digital mode enthusiast will be better served with a common website where all can go, and reliably catch news of who is active, and on which band. The Hamspots and PSkrepoter partnership seems to be the best site. For those married to all three, my link to them all on one page is still available via http://www.obriensweb.com/skedpskr4.html Andy K3UK Owner.

[digitalradio] ALE and protected frequencies in the USA
I have received three emails in the past 3-4 weeks suggesting that the FCC has an application to protect certain HF frequencies and reserve for exclusive ALE use. Two emails also suggest that people operating on ALE frequencies have received emails asking them to NOT use the frequencies . Is this just junk information ? Has anyone else heard from people objecting to others using frequencies commonly used by ALE operators. ? Can anyone verify that the FCC is considering an application to exclude non-ALE stations from certain frequencies ? Andy K3UK

[digitalradio] Amazing ! Multispsk with SDR 48 Khz RS ID
While I am not to first to test this, I am happy to have MY first success with Multipsk, an SDR, and RS ID. Patrick should get a Nobel prize for this, it will make digital mode hunting even better . It works as advertised. Phil KA1GMN and I did a test. I placed my received on 18090 and Phil sent an RS ID (he was CQing) on 18100 As you will see in http://www.obriensweb.com/phil.jpg , the wider (48 khz wide) Multipsk detected his RS ID , sent an audible beep to my PC , and alerted me visually that an RS ID was detected up 10 kHz. This could be very useful for bands like 20M where there is quite a wide range of frequencies for the digital modes (14065 to 14109). I finally did this by stealing my son's PC , just to test. My Pentium 2.3 single core CPU would not handle the load, but my son's Pentium single core 2.7 CPU did so, easily. See http://www.obriensweb.com/multipsksystem.jpg for system info. Thank you Patrick. At the moment, Multipsk is the only application that lets you feed wide I/Q data to it so that you can decode signals wider than the normal audio bandwidth, Andy K3UK

In most cases, it is because they are sending with too much power. Ask them to decrease power, and the extra upper/lower signals just disappear. Sometimes its difficult to figure outw here they are listening, due to so many strong signals from the same station.Like any other mode, one should always start out with the lowest possible signal, and if they dont answer, increase it a few watts and try try again. We are supposed to use the least power needed for a contact. Thats part of the Amateur operators code, isnt it?

[digitalradio] ROS Modulator- Frequency-hopping spread spectrum (FHSS)
From http://go2.wordpress.com/?id=725X1342site=rosmodem.wordpress.comurl=http%3A%2F%2Fwww.box.net%2Fshared%2Fq4e20pgnef ROS uses a Spread Spectrum technique known as Frequency-hopping spread spectrum (FHSS). In a conventional 16FSK system, the data symbols modulates a fixed frequency carrier; but in a FH/16FSK system, the data symbols modulates a carrier whose frequency pseudorandomly determined. In either case, a single tone is transmitted. ROS modulation scheme can be thought of as a two-step modulation process – data modulation and frequency hopping modulation—even thought it can be implemented as a single step whereby the frequency synthesizer produces a transmission tone based on the simultaneous dictates of the PN code and the data. At each frequency hop time a PN generator feeds the frequency synthesizer a frequency word (a sequence of l chips) which dictates one of 2^l symbol-set positions. The frequency hopping bandwidth, and the minimum frequency space between consecutive hops positions, dictate the minimum number of chips necessary in the frequency word. In the receiver, the received signal is first FH demodulated (dehopped) by mixing it with the same sequence of pseudorandomly selected fre1quency tones that was used for hopping. Then the dehopped signal is applied to a conventional bank of M noncoherent energy detectors to select the most likely symbol.

[digitalradio] ROS band plan , and other modes
Avoid 14075-76 since this is where JT65A is on 20M. I like the idea of us all be around the same place with differing modes, that way, we can hear people calling and do not have to constantly twirl the dial. Since most people's waterfalls , including the one in ROS, are 3kHZ wide , and people's rigs often use an audio range of 3 Khz, I would like to suggest that ROS stay within 3 kHz of where everyone else is. Avoid the PSK31, JT65A, and usual RTTY ranges but have MFSK16, Hell, PSK63, ROS, Thor, Throbx, Olivia, Pax, ALE400, Dominoex and MT63 all in the same area. Close to PSK31 too, that way we can interest PSK31ers to try the odd sounding mode.

I was thinking along the lines of just above the olivia 1000 frequencies. IE above the beacons and olivia but this may only give 1 spot frequency before you hit 14.112 14.101 – 14.112 is for unattended but is also used by olivia and winmor I think, there certainly wouldn't be any rtty in the way lol.

The FCC recently clarified what a repeater is because a group insisted that any time delay meant it was not actually repeating, but their argument lost.

Re: [digitalradio] RTTY and mode selection on radios
FSK is RTTY but so is AFSK. Some rigs support the use of RTTY in FSK while others require a TNC or sound card to generate the tones. FSK on transceivers tends to invoke narrower filters and the frequency you are receiving is displayed differently. The serious RTTY guys tend to prefer FSK. This post from the N1MM Logger reflector illusrates some issues.. (see also http://www.mcwa.org/AFSKvsFSK.pdf) Doug Haft wrote: Are you running AFSK, or FSK? Does this mismatch in frequency happen on every spot, or randomly? If AFSK, which sideband, LSB or USB? I haven't thought this trough, so I might be off base here, but its possible the spotter is running AFSK. So, their rig is in USB (or LSB). Their audio tones will be up (or down if using LSB) in the sideband. The freq on their rig will be offset from where the tones really are. If you're running FSK, you'll tune to the freq they spotted, but the target station won't be there! Worse yet, if you're in USB running AFSK and the spotting station is in LSB AFSK... the spot he puts out will be quite a ways from where you land as a result of clicking that spot.

Is there a reason for this? I am asking this because I have listened to some RTTY using either USB or LSB dependent on what band I am on and could copy it with any software programs I have but then switched to the FSKmode on the radios and loose the signal completely. Is this mode just for the older ancient RTTY eqiupment to interface with the radio? I haven't tried to send any RTTY yet but planning to be on the air next weekend for the NAQP RTTY contest from the Red Cross station in Ann Arbor,MI. James W8ISS
[digitalradio] FCC Spread Spectrum
3. Spread spectrum is a technique whereby the energy of the transmitted signal is distributed over a wide segment of spectrum. The signal power density can be very low and the duration of a transmission on any frequency in the segment of the spectrum can be but a fraction of a second. SS systems, therefore, can evenly share all of the spectrum in the available frequency segment, despite a number of stations transmitting simultaneously. They can often share the same spectrum unobtrusively with non-SS systems because the transmissions may not be noticeable to a casual listener. 4. Special Temporary Authority to experiment with SS transmissions was granted to 25 amateur stations affiliated with the Amateur Radio Research and Development Corporation 16 years ago. These experiments involved on-air evaluation of different spreading rates, frequency ranges, and interference to stations transmitting other emission types. On the basis of these tests, two types of spreading techniques -- frequency hopping and direct sequence -- were authorized by our rules. Under our current rules, SS transmissions may be made on authorized amateur service frequencies above 420 MHz with transmitter powers up to 100 watts. Since introduction of SS in the amateur radio service, numerous commercial applications of SS have also evolved, including personal communications services, remote meter reading and position locating.

[digitalradio] ROS experiments
My experiments (many receptions and 2 transmissions) today with ROS 1 and ROS 16 shows that it is quite an effective mode. Congratulations Jose. Of particular interest to me were the several occasions where I decoded a signal that was not visible in the waterfall or audible to my ears. It will interesting to see if Tony K2MO gets a chance to put this through the Pathsim tests and compare it to Olivia. My guess is that it will be close to that of Olivia 1000/32 , perhaps within 2-3 dB. I should also point out that I think the software is well designed and layed out. Over the years we have had many modes come and go. I suspect that in 2-3 years time, ROS will still be used. Andy K3UK

Andy, I think you are incorrect. 50% of the 89 messages , so far, are related to the legality in the USA issue. You are also preaching to the choir, here.

How did you end up with such restrictive amateur licensing practices that experimentation with any new ideas is almost regulated away? Or worries the users that they make be flung in prison for transmitting them :-) I seem to recall exactly the same arguments about PSK31 when it started. Why not make representations to your licensing people to relax the rather ludicrous (to us, anyway) restrictions on signal bandwidths versus data rates and let amateurs look after their own bands. Legislate-out what is really bad, not legislate-in just what a committee thinks is reasonable on any given date. Modern HF data modes have to be wide if they are to withstand the ionosphere. Something military communications discovered decades ago. The UK, and probably most European, licences don't dictate modes and bandplanning, they leave that to amateurs themselves to police. The licence just limits frequency bands, power etc. to avoid problems with other users. Bandplans are not mandatory as far as licencing goes - although people who break them do fall-foul of the operating police sometimes !

[digitalradio] QRV 14080 ROS 1 and 16
My station is listening for ROS signals on 14080 USB (dial). I am interested in how ROS does across the Atlantic around 10-1300 UTC when 20M is usually marginal. Hopefully I will receive some European or African signals. Andy K3UK Fredonia, NY FN02

We just went through this with wideband/spredsprectrum on 6 and 2 meters . I dont care what mode anyone uses as long as it does not cause problems for others. SHOW THE FCC IT WILL NOT CAUSE PROBLEMS and go from there ... Showing that each mode should not cause problems, is not an FCC or IARU requirement , if by problems you mean that people get upset when it is used on their frequency. It IS a problem if people use any mode without checking to see that the frequency is clear, but other than that... staying within the allocated part of the band, is all we are expected to do. It makes sense to stay clear of known sections, like the PSK31 area, JT65A areas, RTTY DX calling area, but ROS has as much right to be used within a ham's allocated part of the band, as any other digital mode. Just listen first, and use it (if legal in your country). Andy K3UK

[digitalradio] Rethinking digital mode band plans-developing a solution
Just some thoughts, critique welcome. If we think about HF digital QSOs there are 5 general types. 1. Weak signal propagation probes that are frequent in nature and regularly used by hams around the world (JT65A, ROS, WSPR, SLOW CW), Usually the exchange is a signal report, callsign, and location. No Conversation 2. Conversational digital modes that are hugely popular, very active, and can include brief contest exchanges or Dxpedition quick exchanges. (RTTY, PSK31/63,). 3. Message delivery digital modes in common use, quite active, and used at times for emcomm Pactor, Packet, standard ALE, Winmor, PSK125-250, Often fairly wide signals 4. Conversational rag0chew digital modes that are very robust and used by a small group of hams during weak signal or low power conditions ( Olivia, Hell, Thor, MFSK16, ALE400, DominoEX, Throb. ThrobX) 5. Experimental messing around by digital mode enthusiasts, testing all kinds of odd modes just to see how they work. No more than 1000 hams world wide. Modes include Olivia, Hell, Thor, MFSK16, ALE400, DominoEX, Throb. ThrobX, PAX , Chip, FPSK, RITTY, PSKAM, QPSK, Contestia, RTTYM, ASCII, Voice, ROS 1, JT64, JT6M, MT63, A persistent issue (I avoid the word problem because I do not think it is) is that each of the particular interests wants to have a common meeting place on the dial. For some uses, it makes perfect sense and for others it is not really that essential. Message delivery systems and weak signal detection both would logically want a common place on the dial. Other modes can be found by twirling the dial or using alerting system like PSKreporter or Hamspots, but sometimes you miss a CQ because you happened to be down the dial a tad. So, what plan , a voluntary one, could this group of 4000 hams/SWLs , develop that would make sense and demonstrate the concepts of hams working cooperatively on such matters.? One that did not wait for regulatory solutions. It might make sense to start with what is currently working or so dominant that attempts to change would be futile, right ? So, changing PSK31 and RTTY operations is out of the question. WSPR and JT65A operations seem well policed by the enthusiasts of these modes. So that would take care of items 1 and 2 above. What about item number 3, above ? I'm inclined to agree that this group might work best if allocated a small section of each band, probably in band segments that allow unattended operations. PACTOR is an issue because there are so many frequencies used. In reality though, Pactor, Winmor, PSKMAIL, ALE, Packet, and APRS-Packet could all meet their goals with just a TOTAL of 6 frequencies per band. 2 frequencies per band for Pactor, one for Winmor, one for PSKmail, one for ALE digital, and one Packet. Six voluntarily protected channels per band, except in emergencies. That would leave items 4 and 5, above. That's mostly the members of this group, Since there are 4000 of us, 4000 collective brains should be able to develop a band plan for a) Conversational communication and b) experimental messing around using a mixture of wide and narrow modes. Ideas ? The outcome , in my mind, would allow a new ham to consult a chart that looks something like.. 160 80 75 4030 20etc, etc. PSK31 (general) .xx to .xx to . to to to to etc, etc. RTTY (dx).xx to .xx to . to to to to etc, etc. RTTY (general).xx to .xx to . to to to to etc, etc. Weak Signal Exhange . to to . to to (JT65A, WSPR, QRSS, ROS1, etc) Weak Signal Rag-Chew .xx to .xx to . to to MFSk16, HELL, Olivia, Throb, etc) ) Narrow Digital Experiments . to to . to to to to etc, etc. Wide digital experments .xx to .xx to . to to to to etc, etc. PSKMAIL XX XXX etc, etc. Packet XX XXX etc, etc. ALE XX XXX etc, etc. Winmor XX XXX etc, etc. PACTOR and
