[digitalradio] virus warning
i run two machines xp/win7. both have installed the microsoft security essentials. of late, i am getting a pop up warning about a trojan:win32/jpgiframe.a on digisites loading and when it refreshes.G0HWC,s web page with all the thumbs from various sstv ops does the same. the security program can eliminate the trojan, which is good, but a false positive all the time is a bummer. anyone to comment. david/wd4kpd -- God's law is set in stone : everything else is negotiable

[digitalradio] Automatic sub band frequencies
Andy, If you are looking at frequencies for your Winmor operation in the auto control subbands I can suggest some frequencies to avoid since they are the primary NTS Digital operating frequencies..with Pactor 1, 2, and 3. NTS Digital for the most part only operates in the auto control subbands and we are using Winlink Classic which does have a busy detector. 3591.9 3593.97100.4 7102.4 10140.9 and 10142.9 14095.9 14097.9 and 14112.4 Good luck . 73 Dave WB2FTX Eastern Area Digital Coordinator- National Traffic System Digital

Re: [digitalradio] Re: Opposing 60M proposal
You further reinforce my position; the amateur radio service is not going to support long haul emcomm infrastructure. It doesn't matter what color you paint it. If the amout of wasted envy spent on lamenting P3 was devoted to promoting the Amateur Radio Service; then it may have a chance of surviving a few more decades. The others who take a serious look at your stance, and the credibility the ARS stands to lose have a good idea about who is destroying the villiage. Of course I have heard the same complaints about WINMOR; I live on planet Earth. By the same token, if we had to resort to smoke signals, the same group would be protesting unattended operation of fire. To me, the discussion is a passing amusement. I don't anticipate the need to generally waste time or effort trying to use Amateur Radio Service spectrum for any useful long haul communications in an emergency; except voice when I may need a larger audience in an affected area. The SATERN nets in the first week of the Haiti response brought out the jammers. They had the same hatred for sustained net operations as the anti P3 crowd have for effective emcomm infrastructure. The end result is the same; ineffective interference... Long Haul Emcomm has migrated to NTIA spectrum. I am reaping a great crop of effective communications there. How well did your crop come in??

RE: [digitalradio] Why does the ARRL continue to push for Pactor III support...
In a channelized setting, PIII will not exceed allowed bandwidth. But, to answer your question about why the ARRL pushes PIII; relevance in emergency communications for current sustainability of allotted spectrum. When there is a race for control of long-haul spectrum (for which there is a renewed interest among military, agency and NGOs), it is nice to have a dog in the hunt. But, the move to give more legitimacy to Pactor III (PIII) in the ham bands will fail, as ultimately the Amateur Radio Service's claim to all of the spectrum they currently enjoy.

RE: [digitalradio] Opposing 60M proposal
This would be a good plan to insure that the Amateur Radio Service is treated as hobby-only communications. However, to be able to send traffic that is formatted in usable format for the players in an emergency, it takes a bit more than FEC, or throttled back ARQ. There are none of these problems or restrictions on NTIA spectrum, and it is another reason that the ARRL probably feels in peril as far as defending long-haul spectrum for the Amateur Radio Service. I run a 24/7 RMS WINMOR server. I run it on NTIA spectrum. I have had a P# controller in the past, and will probably invest in another one in the future. I wouldn't even consider running a RMS station within the Amateur spectrum; it is not worth the effort or wear and tear on the equipment involved to devote an emcomm asset where it has the least chance of doing anything useful. If things were different, I would put up a second station 24/7 within the Amateur Radio Service spectrum. It simply isn't worth listening to the whining. Also, the potential for being effective in an emergency is too heavily weighted toward Federal spectrum for the same reasons that the Winlink/P3 whining never ceases when it concerns Amateur spectrum. You reap what you sow As far as the bandwidth argument, remember, it is hard to consume like a humming bird and output like an elephant. The ARRL is certainly considering the trend that started in the early 90s when the FCC was defunded, and spectrum auction refarming was created. It is now part of a self-fulfilling prophecy, and will play a large part in the continuation of amateur radio service having use of the spectrum it currently enjoys..

The pupose of the yes maybe boring everyday messages is to keep a cadre of trained message handlers for those times when ham radio is called upon to provide communications during disasters and other emergenices when other modes of communication are down or otherwise unavailable, including the World Wide Web. The National Traffic System exists and has operated for many decades in this fashion. A natural extension of this is NTS Digital which indeed does operate automatic message handling systems primarily using Pactor and operates concurrently with the traditional manual NTS at all levels. However NTS Digital for the most part still uses what has become to be called Winlink Classic where almost all of the forwarding is done via RF. Yes we do scan, but Winlink Classic also has a busy frequency detector built into its scanner function. While not perfect it does result in inhibiting many connections when the frequency is busy. Personally I have seen it work upon detecting CW, RTTY, Pactor 1, PSK31 and some other digital modes and even just plain carrier. NTS Digital operates almost exclusively in the very small existing automatical control subbands. Indeed during RTTY contests when many of the activity moves into these autocontrol subbands our traffic handling ability is severely affected due to the busy detectors in the software. How big is this operation?... For March 2010 the NTS Digital system in Eastern Area which comprises most of the East Coast and the 1, 2, 3, 4, and 8 callsign areas and Eastern Canada handled over 6000 messages via the digital systems. Similar traffic levels are also posted by the other two areas, Central and Pacific covering the rest of the US and Canada Dave WB2FTX Easten Area Digital Coordinator- NTS Digital ARRL --- In digitalradio@yahoogroups.com, Andy obrien k3uka...@... wrote: A quick fix for this entire mess is to suggest to those running automated traffic stations to use the World Wide Web. The web is faster, less likely to be affected by atmospheric changes, and remove a thorn in the side of many ham radio operators. I have only intercepted messages being relayed by an automated traffic handling station a few times. The traffic was dull and trivial. It was hardly worth the mayhem now being caused by their operation. Some may disagree with me on the point of traffic being trivial. I just cannot find happy birthday grandma to be very important.

RE: [digitalradio] WINMOR good
Andy, The RMS WINMOR station is always in contact with one of the CMS (Common Mail Servers). When you negotiate a connection, it checks for any mail waiting for your call. You can also send mail through the RMS WINMOR Station. It doesn't have to be to a winlink.org address. There is also a RMS Relay for store and forward, in case the RMS WINMOR station you connect to has loss of internet. In that case, when you disconnect, it will connect to another RMS Station via RF and pass your traffic. I haven't fully implemented RMS Relay in my RMS WINMOR server, as it is only for Pactor 3 at this point. I expect that will also change in the future. I wish I had a better grasp that what I indicate here. It is a nice network; much wider in it's scope than most realize.

FYI, despite some limitations on noisy HF (like all modes) , my view is the the RMS package is now a complete one. A application that fills the void mentioned frequently, namely the lack on HF on-ramps. With Winmor HF stations now connected to the WINLINK system, hams can easily communicate via Internet and without Internet. Example, today I connected to KN6NB-5 on 30M, just to see if the upgrade was working. I connected and received an email from another ham that was sent a couple of days ago. I had not checked mail for a few days. How I got the email, I have no clue. In other words, I don't know how it found me, I have not kept up on how Winlink works. I assume that I checked in to a WINMOR winlink station, it checks WINLINK for any mail for me by using the Telnet link and then sends me the mail via HF winmor. While many may have issues about the winlink concept, it now does do something effectively, gets messages to a destination via variety of methods ..error free.

Before my reinstall of WinXP this past weekend, I was using WSJT to operate JT65, the logbook in HRD/DM780 to log the exchanges, and HRD Utilities to upload automatically to LoTW. I had no problems with this, but suddenly after the OS reinstall I can no longer upload JT65 as a valid mode. In my LoTW QSO listing, I have 42 entries all with JT65 as the mode, so I know that it can accept it although a lot of the FAQs say that it should just be data. Any ideas what happened on my end to cause this, and most especially, what I should do to get back the ability to upload JT65 as the mode? Thanks in advance, Dave Dave K3DCW Real radio bounces off the sky

I apologize for this, but I found the solution. After Googling this for sometime and finally asking the group, the very next link I clicked on had the answer. If anyone else is having this problem, simply google ARRL Cert.tq6 and download the file (https://p1k.arrl.org/lotw/config.tq6). Double click on it to run it, and all is fixed.

You could be hearing anything there, from a military radioprinter to DGPS navigation systems. The 80m band is a shared band, depending upon the specific frequency. Let's assume you were around 3580kHz. That frequency is an amateur-only allocation in the US, but is shared with the Fixed and Mobile Services in Region 1 and 3. There are many European military stations active in these bands, so you easily could have heard one of them. Alternately, you could have some source of local interference.

[digitalradio] MT63 specifications
An excerpt from Pawel Jalocha's source code distribution: The MT63 modem is intended for amateur radio as a conversation (RTTY like) mode where one station transmits and one or more other stations can listen. In short, the modem transmits 64 tones in its 1 kHz bandwidth: the audio range for the tones is 500-1500 Hz. The differential bipolar phase modulation is used to encode 10 bits of information per second on each tone. The user data in the form of 7-bit ASCII characters is encoded as a set of 64-point Walsh functions. The bits are interleaved over 32 symbols (3.2 seconds) to provide resistance against both pulse and frequency selective noise or fading. The character rate equals to the symbols rate thus the modem can transmit 10 7-bit characters per second. This modem can as well run in two other modes obtained by simple time scaling, the possible modes are summarized here: BandwidthAudio RangeSymbol Rate Character Rate Interleave / Char. 500 Hz 500 - 1000 Hz 5 baud 5 char / sec 6.4 or 12.8 sec 1000 Hz 500 - 1500 Hz 10 baud 10 char / sec 3.2 or 6.4 sec 2000 Hz 500 - 2500 Hz 20 baud 20 char / sec 1.6 or 3.2 sec For each mode the interleave factor can be doubled thus each character becomes spread over twice as long period of time. The MT63 modem is made for single side band operation. The audio generated by the modem (sound card output) is applied to the SSB modulator. On the receiver side, the output of the SSB demodulator is put into the sound card input. The envelope of the MT63 signal is not constant as in other multi-tone systems - it is rather noise-like. One must be carefull not to overdrive the transmitter. The receiver of the MT63 is self-tuning and self-synchronizing thus the radio operator is only required to tune into the signal with +/- 100 Hz accuracy for the basic 1000 Hz mode. The modem will tell the actuall frequency offset after it is synchronized. The operator should not try to correct this offset unless he is able to tune very slowly his radio receiver, because the MT63 as a low rate phase modulated system does not like sudden frequency changes. The MT63 is a synchronous system and it relies on the sampling rate to be the same at the receiver and the transmitter. At least the sampling rates should not be different by more that 10^-4. MT63 samples at 8000 Hz thus if your card runs at 8000.5 it's probably OK but if it runs at 8005 Hz it's not good ! An extreme example can be my Soundman-16 (PAS-16 clone) which when asked to run 8000 Hz tell me, that it can only do 8008 Hz and it reality it runs at 7910.3 Hz which makes an error of more than 1% - far too much for the MT63 even at infinitely good S/N. My other two cards (DSP-16 and Ensoniq 1371) are more reasonable: they show an error of 0.3 to 0.5 Hz at 8000 Hz sampling.
[digitalradio] flarq compatible modes
I have received several reports that users have not been able to get flarq-fldigi=fldigi-flarq to establish an flarq connection. I think that the problem might have been a failure on my part to delineate which modes are compatible with flarg. I have updated the on-line documentation for flarq thusly: Flarq can be used with the following digital modem as the transport layer: BPSK all baud rates QPSK all baud rates MFSK all baud rates DOMINOEX 11 or faster (do not use FEC) THOR all baud rates, 11 or faster recommended MT63 - all baud rates, flarq timing should be increased to accommodate mt63 latency for example: MT63-500 requires flarq be set up with: Wait time 30 seconds Timeout 300 seconds Tx delay 500 msec Beacon interval 30 seconds on both ends. Watch the flowers grow :-) Probably the most important thing for persons trying the flarq / fldigi suite to know is that they should not use DominoEX-FEC or Olivia as the transport layer. These modes suppress the transmission of the required control codes for the flarq data stream. 73, Dave, W1HKJ

If you need help with any aspect of running the NBEMS suite (fldigi, flarq, wrap) you will receive a more timely response by posting your questions and problems on the yahoo group dedicated to it's support: nbems...@yahoo.com You should be prepared to enumerate what version of each of the programs you are testing and what hardware you are using for the test. You will probably be asked to provide further information regarding the type of transceiver control being used on both ends of the qso. The person assisting will also ask for the timing settings and what mode you are using for the flarq tests. If you have programming skills that complement your operating skills you have the opportunity to contribute to making any or all of these programs better for yourself and the amateur radio community as a whole. All of the NBEMS programs are General Public License (GPL). That means the source code is ALWAYS available to you. Contributing in this way is far more noble than simply grousing about failures that may or may not be attributed to the software. Binary and/or executable files are simply a convenience for those who are not able to build the application from source. Some mention was made about receiving an OS message during program startup. I have only seen the message on VISTA and it is almost always associated with a change in h/w between a shutdown and subsequent restart of fldigi. Did you unplug either your microphone, line-in, or speaker out from your sound card? If you did then VISTA reports that the sound system is not available. Fldigi is trying to access the sound system and fails (at the OS level) to do so. There is probably a way to avoid this problem, but the Linux programmers who work on fldigi are not aware of how to do so. Here is an opportunity for a Microsoft skilled programmer to lend a hand (see para above). 73, Dave, W1HKJ

Re: [digitalradio] Digital modes and old husband's tales
Hi Andy...Ill add a quote from the Instruction Manual for the Kenwood TS140S While 100 watt transmissions are possible when using short duration modes such as PACKET continued operation over a long period of time might cause overheating. We recommend that you reduce the transmitter power output to 50 watts whenever using one of these modes i.e PACKET, AMTOR, RTTY, this is easily acomplished thry the use of the front panel PWR control on my homebrew interface i have a pot that i use to set the drive to the TX so that i read approx 50 watts on the Revex Power meter on the antenna output. was using 65 watts one night on PSK and was told that my signal was drifting a bit.the internal fan didnt come on but the heatsink was awfully warmhave since put 2 computer p/s fans on top of the heatsink at it runs cooler and no drift on tx ok thats my dimes worth hi hi 73 David VK4BDJ Andrew O'Brien wrote: The replies to Ralph's question about audio levels appear to be sound advice and certainly in keeping with what has been advised since sound card digital modes burst upon the scene. I wonder how accurate it is though?I have seen a few serious hams argue that no ALC is not really the case, that some ALC can be OK. I have also seen mention that the no ALC issue applies to some modes (like PSK) but not to others like (JT65A). I also wonder about the half-power advice that some advise. With my homebrewed interface, I could never get much above 40 watts before some ALC began to show. When I switched to a commerical interface with good isolation (Microkeyer by Microham) I can almost always get 100 watts output without any ALC action. I have not received any negative reports about my signal . If I run 100 watts SSB for phone contacts, why would I not want to do the same for digital modes assuming the signal was clean ? . Yes, I would agree I should not run 100 watts if communication was possible with less power, but I don't think a brief PSK CQ at 100 watts is going to do much more harm to my finals than a 3 minute ragchew at 50 watts, phone .

RE: [digitalradio] Re: Use the *$%#ing RS ID!
This is not an official answer, but I will take a stab at it. RSID is an Olivia transmission at the beginning of each digital transmission that contains the operating parameters used by the originating station. RSID stands for Reed-Soloman ID. Wiki Here: http://en.wikipedia.org/wiki/Reed%E2%80%93Solomon_error_correction RSID can be coded into the digital sound card software at the author's discretion. The modes it is most useful on are model like Olivia, MT-63, Contestia, or modes that have multiple combinations of number of tones, bandwidth, interleave, etc. Modes that offer many configuration options but sound relatively alike are easier to master using RSID on both ends. After becoming accustomed to the varying sounds, it becomes less of a concern, to the point that you can recognize them by ear, or proficient enough to decode on the fly. Currently, MultiPSK, HRD and (I believe) FL-Digi have it as an option. I am unsure of the FL-Digi implementation. The software determines if it is toggled off after first IDing a transmission or stays in constantly, once selected. Both originating and receiving station must have it enabled. It is enabled according to the Author's instructions, which is dependent on how it is implemented in each software package. This reply is based on limited usage of RSID when it first became available on MultiPSK a few years back. I never used it enough to really become proficient, but this is my basic understanding of how it works.

RE: [digitalradio] Hook up TNC and Soundcard to same radio?
With the capability to cut and paste a received message from MT-63 and send it out via Winlink, the 10 second turn around is very close to simultaneous operation. If you want to make things difficult for your self, or discourage others from using the available transport layers, you can advocate having 3 rigs and as many antennas. Here is an example of a complete Transportable outfit for rapid deployment: http://www.se-hams.com/html/emcomm1.html A single antenna (DX-CC, BW-90, Screwdriver on a tripod, etc.) is all that is necessary. The setup above allows voice, sound card modes, External DSP controlled modes (Pactor III being the main one), has manual tuner with bypass mode. The rig covers from 160m to 70cm. A separate UHF/VHF setup would be a nice addition to the setup above. A FT-8900 to a quad band tripod mounted antenna, would be the icing on the cake.

RE: [digitalradio] SSB Phone versus other modes
Andy, This is a topic of discussion that is raging on behind the lines in Emergency Communications also. The fundamental thing that many miscalculate is how the Intel that is to be sent digitally is gathered and relayed to someone with the capabilities to digitize In this debate, a lot of babies have been thrown out with the bath water already. Please keep the most rudimentary concept of communications in mind in this discussion. It is like factoring to prime numbers. One day, everyone will have a total mobile digital station as an option in their cars at point of purchase. However, we aren't there yet, and we have to rely on what is available if we are to offer a useful service to the community to pay for our keep (and spectrum). Voice Ops will always be an option; especially in the first 96 hours when everyone is scrambling to restore enough damaged infrastructure to get back on the air. Again, as hunter gatherers someone must collect the Intel or ground truth that is to be sent via digital means. However, Amateur Radio is less about public service now than it has been in the past, and many don't consider Emergency Communications as something they are interested in. As far as DX goes, that is another battle altogether. Many who chase weak signals are deeply involved in the modes that were available when they were first licensed. Some (an un-known quantity), don't have email, internet or computer access. Some have never had their hands on a typewriter; much less a keyboard. Some don't own a microphone. To them , the topic is a non-starter. To the technician who has stayed on weak-signal VHF and above long enough to learn about propagation patterns, coax losses, antenna gain, AOS/LOS, line of sight, etc...These are most likely to continue to learn as they progress in their license upgrade path. They tend to see the full picture, and having to work harder for each line of sight or tropo-enhanced contact already have fairly well sized up the importance of good operating techniques, and what is needed to get the job done. They have already found that you will make more contacts on HF with a wire by mistake than you will ever make above 50MHz using proper operating techniques, a good station that is properly put together and mindful every step of the away of the losses and need for efficient operations as they move from the approximately 7MHz total of HF spectrum to the Gazillions of MHz of spectrum available to them, if they will develop the gear and skills to use it. They will be the ones that may carry 20th Century technology into the 21st century. The one day extras that come in to a test session with no license and exit with an extra; not so much. The CW ops that can't find a Microphone, but have a half-dozen keys around; not so much. Folks that enjoy and are heavily invested in ESSB; not so much Folks that are equally involved in both Voice and Digital ops, and understanding the need for each, and at what point in the timeline that need is most apparent; preaching to the Choir.

[digitalradio] The next big thing - Using Swarm Intelligence
Excuse the newbie's lack of knowledge, but... Rapid expansion followed by slow consolidation. This is the way of business and technology. What we have been seeing over the last decade or so is the rapid expansion (diversity) of digital communications schemas. Eventually, market forces will prune the tree and only a few major branches will be left. Some minor branches will survive as museum pieces used by a small collector-antique community. Alternatively, a new digital mode that will either be superior to all others, or will dominate others, as to create a barrir to entry in the market. For example, when Windows and MAC took over the personal computer OS market. Where am I going with this? Why do we have to wait for someone to invent the better mouse trap? We can design it as a community. Perhaps its time for us as a community to develop the specifications for this next big thing. and send it out to the ether for programmers and technologist to build. Specifications: 1. Simple and easy to hook-up for the average computer user. Ideally only requires software, cables, and the Ham's existing transceiver. 2. Inexpensive 3. Open source code and documentation 4. Excellent documentation within source code and within manuals 5. Able scan beacon's and make suggestions for the best mode of operation given the users frequency. 6. Consists of a set of communications protocals and methods to enable it to determine the best format to use given bandwidth, power, band noise, information density, etc. 7. Uses low-bandwidth low baud rates for initial contact and then quickly shifts through machine-to-machine communication to establish the best connection using the best communications schema given the conditions. 8. Can repair bits. 9. Uses standardized tokens to send and recieve often used letters, words, or phrases between machines. 10. Can send any combination of text, images, and speech within the same transmission given enough bandwidth. 11. Can enable the connection of many different Hams in one call working at the same time. 12. Can interface with standard logging software. Well here are the first dozen from an inexperienced newbie that believes in Swarm Intelligence. Perhaps if we all write a solid Specifications document we could next pool money and create a prize to the group that can create the first robust solution for us. Well enough of my soapboxing. 73

I own a Tak-Tenna. I selected it because I have almost no space on my lot for a dipole. First, it is easy to build. Second, don't try this antenna without an antenna analyzer. I have the 40 meter version and it works. During the worldwide SSB contest I was able to talk to Finland, New Zealand, and Austrialia, but was it the antenna or that these guys had 65 foot and higher towers with beam antennas? Based on my contacts I think this antenna does well when the other guy has a beam on a high tower. By the way, there is enough public domain materials on various versions of this antenna around that you could build your own pretty easily.

RE: [digitalradio] Easypal in MARS
Paul, Glad to hear Navy is giving it a try. The rest is grossly off-topic, but I feel the need to expand my understanding. On the Zero, it is a sore point across services, as is the full call debacle on initial check in that I believe came from Bo's influence. I can declare abbreviated calls are authorized, before I establish ANCS, and take 5 to 8 check ins per minute with out duplicate transmissions. In many cases, using abbreviated calls, I can get an entire working net of about 20 stations, establish ANCS, make the call for emergency or priority traffic, have ANCS make the same call, and have 54 minutes for training, administrative business or emergency net operation. Since we have to use full phonetics (Our prefixes are more complex than NNN), and we never fall back to Abbreviated Call Signs (Our prefixes are more complex than NNN), and we never give a call sign non-phonetically (our prefixes are more complex than NNN), and we use FEMA Region designators to be able to geographically determine the effectiveness of the net (our prefixes are more complex than NNN0) We find that the attempt to require full call signs on initial check in to be a surefire way to create Chaos. Also, in preferring the concept of training the way we would operate in an emergency, we have generally found that requiring full calls to NCS, when the net can only have ONE NCS is as well thought out as being asked if we want fries with our fries, when we just order fries. One day, I may be fully expanded enough in mind and maturity to fully understand the full call requirement. I'll bet you guys are still laughing about that part of the new voice SOP.

RE: [digitalradio] Easypal in MARS
Andy, At leas one of our members has been in touch with the developer and made requests to simplify the cut and paste options of the text transfer. There have been numerous updates, and the text transfer has been updated to make it more adaptable for use to insert blocks of text for broadcast. All the other functions of the BSR and FIX apply to the text function. If you were tasked with sending the participants of a net a rather intricate set of instructions, taskings, or specifications, and had to be sure each member had received it properly, you could spend a major part of an hour with requests for fills or repetitions, words phonetically, groups, or numbers. With easypal, you get what you get on the original transmission, and you send the BSR (Bad Segment Request) and the sending station sends the FIX file containing only those segments. Each member receives benefit of any bad block that they missed in a FIX file sent to another member, since it is a broadcast (non-connected) protocol. If you were involved in dial-up file transfer in the 80s, when text files were captured you will remember that it took as much time to capture a space as it did a letter. Transfer protocols were created the compressed ASCII on the fly to improve through put, I seem to remember J-modem, I-modem, y-modem and others that had the compression routines built in. I remember using a shell on ProComm Plus to allow choosing up to 14 different transfer protocols, dependent on the type of file you were transferring. I had at least 9 options available on the BBS I ran from the late 80s to the mid 90s. If Easypal can send a perfect high resolution picture in a 20K Wave file, you can imagine how small a 2 page document would be when converted to binary, data digitized into a wave file then sent in this manner to assure error-free reception. The repeater function allows the file to be sent to a central repository then retrieved individually by the members who could retrieve the file list. The program is getting very polished, and has great potential. I don't know if it is getting much exposure in all regions, but it is a valuable tool for the toolbox. As far as acceptance, MARS is a fairly diverse group of folks. Some are up in age, some are retired and homebound, some are fit and ready for deployment at the drop of a hat. Since there are requirements for continued membership, participation requirements, reporting requirements, requirements for pulling NCS and ANCS, requirements for NIMS compliance, now the requirement for a General or higher license Then you can see that the members have to meet certain obligations and benchmarks to continue to be a member. With this in mind, the program has some fairly receptive members, who wanted to go further in their service in, and understanding of the art of communications.. Most of them are quite willing to try something new. We haven't spent the degree of time on Easypal as we have with MT-63. But with each region having up to 10 one hour long nets scheduled each day, and each net has the requirement for some sort of training, and many members are uniquely qualified in one aspect of the training or another, it becomes fairly easy to see how a new mode can be introduced, explained, setup and operation help given, and results seen within the course of an hour and in an interactive manner in a disciplined net structure. Is MARS the silver bullet? Hardly. It has it's growing pains as much as any organization. In Amateur Radio, if there is a community that has 3 Amateur Radio operators, there will be 4 opinions on every subject and pretty soon there will be the need for 5 repeaters to be established so they can communicate with their group. We all can key the Mic, but many times, as communicators we show that we can send out a signal, but actual communication is not often what results. The organized format of MARS, the requirements, continuous training, forward looking (not driving the car by only looking through the rear-view mirror), the disciplined net structure. All of these things help form a group that is dedicated to the art of emergency communications. Once that subset is created, most of the QRM is left behind, and they can concentrate on the task at hand. Overall, I am usually fairly happy to be associated with MARS. BTW, the General class or higher requirement was recently introduced, with the main purpose to allow interoperability with ARES, RACES and other Amateur radio groups. So we would sure like to see some organized effort for both groups to start working together.

RE: [digitalradio] SCAMP and Cynicism? - Nope, no way.
Dave, It is a good start, but I am afraid the lines were drawn long ago, and the opponents are so emotionally involved that nothing would appease them. I would really expect the only thing that will satisfy would be the total abandonment from the amateur bands and 100% move to NTIA spectrum. All the restrictions that were in place so the software could be freely given to Amateur Radio operators to alllow them to better meet their emergency service obligations required to justify the spectrum they enjoy could be removed, and the Winlink Transport Layer could be allowed to operate flat out and no longer be impeded to meet the Amateur Radio requirements. It is looking ore and more like a win win situation. The end result, less Pactor on Amateur Bands, and far less need for amateur radio operators to assist served agencies in any kind of emergency, unless it is meals on wheels, or another support NGO that only services the emergency responders. I have tried many times in softer ways to hint at this dynamic in the past. Only the future will reveal the outcome. It would be a real shame to see the WINMOR protocol be releases and be a cost-efficient for any amateur operator to send data in the form of choice for those whom they serve in emergency, only to see that the Transport Layer had been taken away from Amateur Radio so it could be fully developed for the served agencies. As you know, you see less and less need for folks who make wood-spoked wheels for wagons, since rubber and steel became the norm for enclosing circular mobility enhancers. Contrary to the opinion many have on my comments, I am basically a voice guy. My involvement in digital modes is secondary, as I know that there is nothing to send until the intel can be gathered to send it,. Also the digital infrastructure has to be put in place in any disaster. The first 48 to 96 hours is usually a knuckle-graggers domain. By Knuckle-Dragger, I refer to what the voice guys are consider to be by the digital guys. I am a knuckle-dragger, who knows the importance of digital, and when it will come into play and what it is capable of.

It is true that the long history of WinLink PMBOs QRMing in-progress QSOs has generated more than a little frustration and anger. Some small percentage of those so affected are alleged to have stooped to similar misconduct -- intentionally QRMing WinLink transmissions in revenge. Over the years, more than one WinLink proponent has stated here that given the anti-WinLink sentiment, that busy frequency detectors should not be incorporated in PMBOs because opponents would exploit them to impede WinLink operation. We must put an end to this situation, which means installing an effective busy frequency detector in each WinLink PMBO. Might this be exploited by WinLink opponents? Possibly, but only for a short while.

RE: [digitalradio] No FCC data bandwidth limit on HF Re: USA ham rules
I know some thought went into that reply, and that it has merit if we are only concerned with short-range communications. However, no matter how wide, narrow, thick or thin the emission, you cannot expect the same range on 1 1/4m as you can on 20m - so I am not sure the statement has any merit in this discussion. This discussion has little effect on some, who have long since vacated the Amateur bands for their serious use of digital signals for anything other than entertainment. However, for those who are limited to the Amateur Radio Service Spectrum, pragmatic consideration should be given to the position the regulating body is in when other services that may offer a tangible and beneficial service petition for the spectrum we enjoy. Could it be used to be more of a benefit to mankind with wider bandwidth emissions, which can improve both accuracy and speed in moving traffic that is also beneficial to mankind? What are the basic requirements for moving traffic? I seem to remember Speed and Accuracy to be a major part of the definition... It is all a relatively moot point... As the average age of the Amateur Radio Operator continues to increase, attrition will ultimately be the deciding factor. Consequently, I appreciate the merits of 2KHz wide digital modes, which are used daily on NTIA spectrum - and enjoy using the keyboard modes as a form of entertainment where bandwidth is limited. It does boil down to a question of if we appreciate the privileges of the use of the spectrum afforded to us, and how we show that appreciation. Many only consider it a right for their enjoyment, some look to a higher calling that may help preserve the spectrum for their grandchildren. Wider bandwidth digital signals as a vehicle for efficient long range traffic handling is an unavoidable fact. It doesn't matter how many temper tantrums are thrown, how many stress-related conditions are created by those who know how to spell automated and common carrier. It is here, it will stay here, and it will be advanced to the point at any signal that meets the qualifications of providing 2 KHz of through put with a minimum guard band above and below it to prevent moving past the 3 KHz assigned to the channelized concept used in professional communications will be used by the less technical forms of transmitting that is afforded to the public. I don't much like being taxed into submission either. Neither do I like a lot of things that I must do in day to day life. The frog often wishes for wings. Some Amateur communicators will always fall back upon their comfort zone when faced with a new concept that doesn't square with what their grandfathers taught them. Maybe we would be a better service to mankind if we specialized in finding a way to send smoke signals without burning organic material or creating greenhouse emissions. That is a fairly narrow-band emission, and it would pay tribute to times gone by and also not be automated or considered common carrier.

RE: [digitalradio] No FCC data bandwidth limit on HF Re: USA ham rules
Except for the fact that PSK has no error correction, no compression, no formatting capabilities and no way to accurately know if the traffic was delivered properly other than read back, your figures are fairly accurate. Fortunately, most Winlink traffic is moved on NTIA spectrum, where it is able to run full speed. I am not a large Winlink fan, but I do like 2K MT-63, and I am encouraged by the 2K WINMOR mode that is currently being tested. I don't suspect much development of the newer wide-and modes will be wasted on Amateur spectrum in the future, as most of the long haul and critical traffic transport seems to be migrating toward NTIA spectrum, and leaving the short-haul for VHF where wideband and closed-squelch operation are a given. It further divides Amateur Radio, but at least those who move to where their assistance is helpful can take advantage of modern technology. For keyboard to keyboard, where nothing more important than Call, QTH and 59 needs to be passed, BPSK is exceptionally spectrum efficient. It would be wonderful if a single piece of traffic could be moved on multiple BPSK streams in a parallel fashion. However, when you factored in the redundancy needed to provided error-free reception, I would wager the end result would consume wider bandwidth and take more time. But, for the 99% that the other 1% are defending by operating in the true interest of preserving the Amateur Radio Service, wideband digital modes are a waste of valuable DX or contesting spectrum. If it wasn't for DXing and contests, us Rabid digital dinks would never get the lawn mowed. :) And Amateur Radio is a Big Tent endeavor; when properly executed, provides something for everyone.

I think you are quit right, Bruce, and the Winlink 2000 network is probably currently the most efficient say of moving traffic, but that interests less than 1% of the licensed hams in the US. A single 3 KHz-wide Pactor-3 channel can, under average good conditions, process about 400 wpm per minute, and this assumes the channel is busy all the time. In comparison, a single 3 KHz-wide channel can accomodate 30 PSK63 stations, all simultaneously sending traffic at 100 wpm, for a total of about 3000 wpm. Since the traffic on PSK63 can be passed in parallel, instead of serially, as on the Pactor-3 channel, the narrowband modes are obviously more efficient overall than a sngle Pactor-3 channel. 73, Skip KH6TY http://kh6ty. http://kh6ty.home.comcast.net home.comcast.net

their motion from one site to another. NTIA spectrum will be the long-haul backbone of RF communications by volunteer communicators. They have accepted the concept of wide bandwidth protocols, as they are already guarding every 3 KHz slice of their spectrum. A 2 KHz bandwidth mode still provides a guard band of 500 HZ on the top and bottom and still stays within the 3 KHz that is designated as a Channel. With each assigned frequency, there is an USB and LSB choice, except when it caused the data to migrate into the Amateur band edges. It is actually well thought out. Why would a served agency want to rely on a communications provider that can't stop arguing long enough to move the traffic? I am in and out of this group as the tide tosses and turns, hoping to see some acceptance of the way things are going to be. I am still optimistic. In the mean time, I am still hedging my bets, and utilizing the spectrum that is available to me to explore new and better ways of getting the job done.

Also ultra high resolution pictures with no scan lines that occupy 20KB of data on each end. 90 seconds to send or receive, with the ability to only request the individual blocks that weren't received properly to be sent again.

Putting this capability together with its automatic adaptibility for conditions, it may be the break though of the year for e-mail messaging. It will not require user knowledge of error correction and FEC, etc., since that will be done automatically, just like it was for the SCAMP mode a number of years ago. What it may not have is the emergency features that I see in PSKmail which is peer to peer messaging and chat along with ad hoc server deployment which can never be possible with Winlink 2000. Put the right protocol with the right solutions and you have a fantastic synergy not possible with any other protocol. I don't think that many of us can agree with you about new sound card modes not having a future on ham radio unless they are of a certain type. They just have to be the right protocol that solves an actual need. 60 meters is off the table at this point since you can not even use emergency data modes on those frequencies. What may die is Pactor modes. Having one protocol sourced by one foreign entity is not a good thing. Open source solutions are a good thing. Will many hams use and actually practice using NBEMS? Thus far I have had no luck in my local and regional area. But then again, I can not even get the NTS folks to consider digital messaging other than Pactor, HI. I don't have any interest in NTIA and no one in our area is much involved with non amateur emergency traffic. I suspect that many areas have the same situation.

RE: [digitalradio] THOR is static-proof (Re: KV9U - MT63)
I would like to remind all, if you are not already aware, to turn AGC off when static crashes are an issue. If you are fortunate enough to operate in a mixed mode net, turn it to fast, or for inland stations, medium. Slow recovery time of the rig in response to a strong signal cannot be corrected by a sound card protocol; no matter how robust. While we are at it, when using MT-63 at 1K long, keep in mind that most software hard codes a starting frequency of 500 Hz, and that is a 1.5Khz total width. It doesn't work well if you have your filters set for PSK, or a narrow-band mode. In running digital training nets for newcomers to MT-63, it is absolutely amazing how many ways can be found to lessen it's effectiveness; primarily due to not understanding where the signal is, where it is going, and how it is getting there. It took me a long time to factor out many of the common reasons it didn't work. That is one of the main reasons that PSK-31 is so popular; even a caveman can do it.

Is you recent on air testing to determine that or some other parameters, such as ability to handle interference, etc.? Not really. I pretty much know what to expect with MT63 because I've been using it since IZ8BLY first released it a long time ago. The most impressive thing about MT63 is how it seems to resist heavy static crashes. I made a few recordings with short segments of the signal removed to simulate this type of QRN and there was little effect on copy. It seems to withstand a lot more QRM than most and will usually print well with a good chunk of it's signal obliterated.

My opinions only, other opinions may vary. :) The other 99.95% of the time is spent making sure the system is a working piece of infrastructure during the .05% of time it is needed. It is a time in which new operators come on line and learn to be a part of the network, where system operators improve their system's effectiveness, where new methods of more efficient operations are tested and perfected, where the outgoing system operators are replaced by newer ones, or more remote areas come on line; which further increases the redundant appeal of the system. This is amateur radio; not Fear Factor. Why should we be so afraid of using newer technology to enhance or value to those we serve? I am primarily a voice operator. I spend time on the air improving my technique, time off the air improving my skillsand technical understanding.

It makes tremendous sense since they are often involved in sending bulletins to their members. With one to many it is possible to have 100% ARQ with EasyPal although it is after the fact ARQ. A bit cumbersome, but practical for insuring a group receives exactly correct data. Unfortunately U.S. hams can not use mixed phone and text digital in the HF bands unless they are sending fax/image. Since most of the NTS traffic is short text messages, we can not do that in the phone areas, so we have to confine it to the RTTY/data portions. 73, Rick, KV9U David Little wrote: Rick, Army MARS is using MT-63 on mixed mode nets with some regularity.

Re: [digitalradio] NTS Digital
As an additional note... Most NTS D is using the various versions of Pactor and have the expensive SCS modems... There are some MBOs still runinng Pactor I with a PK-232 MBX... Most of at least Eastern Area NTSD MBOs are using Classic Winlink (ie. the versions before Winlink 2000) as we feel that RF forwarding of NTS is superior to internet forwarding and not subject to system outages during a disaster Some of the Digital Relay Station are using Pactor with Airmail to post and remove traffic from the MBOs...

RE: [digitalradio] The Basics On WINMOR
Andy, It is a soundcard ARQ mode. It will allow a more economical way to access the Winlink 2000 system, and give a higher through-put than Pactor 1 There will probably be other uses, but I believe that to be the prime reason for it's development. I don't know the nuts and bolts of it, but it has a lot to do with taming the timing cycles needed for a soundcard to negotiate a ARQ connection and handle binary (compressed) data. In the past, there was too much overhead for this to be done with a sound card on a Windows machine; other than for SMS Text-Based messaging. The above is probably a poor explanation of what it is and what it does, but I think it captures the intent.

I have seen the explanation but it implies knowledge of the current P3 emcomm system, can someone break down what they are expecting from WINMOR OTHER than it being a soundcard based mode ? Andy K3UK
RE: [digitalradio] on another note
John, You have confirmed what others already know about P3. I sold my PTC IIex last year, when the Winmor protocol was announced to be in development. It should introduce an ARQ mode to compete with P3, but will not replace it. I had the SCS in a go kit with either a Yaesu FT-897D or and Icom IC-7000, manual antenna tuner, switching power supply, sound card interface, USB to 8 Serial port converter, communications speaker and sometimes an auto tuner. http://www.se-hams.com/html/emcomm1.html That go kit has also found it's way into the Netcomm Magazine, as well as World Radio in the past year. It allowed me to setup remotely, string a dipole (actually put a furniture moving pad on top of the car and a tripod to be a center support, with ends staked to ground) in NVIS configuration. Then, the best demo was to send email (actually SMS messages) to various volunteers (read unbelievers) cell phones. For spice, I could include the location, time and frequency to show how unlikely it would be for me to connect to a RMS at that time of day, on that band, covering that distance. When this got boring, I substituted the rig for an Icom IC-703+ and lowered the maximim operating potential to 10 watts. With that combo, I could connect to around 80% of the RMS stations that I picked based on time of day, frequency and distance. I know there will always be folks that will not accept P3 within the amateur spectrum. It is a real shame, because it could really make the Amateur Radio Service stand out in an emergency with serious loss of infrastructure. As it is, the Winlink system is really concentrating on the MARS services and direct to the served agencies on NTIA spectrum.One major catastrophe, and the lack of the amateur community to move high volume traffic over long distances may bring unexpected consequences if the Amateur Radio Service is evaluated as compared to the MARS services. The jury is still out on that. But, as you have stated, P3 does an amazing job of connecting and moving data at much higher than expected speeds under the worst of conditions. Add the ability to utilize binary (compressed) format with attachments of which the size limit can be controlled on the fly by collaborating with the RMS operator, or event specific, routing formats, and priority determination by subject line... You end up with a protocol that can move a served agency's traffic in the format that they are accustomed to using, to be retrieved by the intended agency, using their WL2K system; already in the EOC, or their agencies support group. Winmor and P3 will serve side by side in the RMS stations in the near future; bringing the best of both worlds. But, when speed, accuracy and ability to cut through the worst of conditions are the criteria on which success is determined; P3 will still come out on top.

RE: [digitalradio] Re: How Can We Push HF Emcomm Messages to the Field?
FWIW, in the response to Gustav It was known that Region 4 Resources would be deploying into the area in support of the Southern Baptist Disaster Relief Organization. Days ahead, info was exchanged on formal net operations in that area to allow members from Region 4 to check propagation and effective communications into what was projected to be the effective area; region 6, which is a fairly big target area. Propagation, time of day and available frequencies were reviewed and a net plan was decided on to allow the best chance for reliable communications into the affected area for 24 hour operations to support the deployed members from region 4 as they traveled into the affected area, in-transit to their various support locations and to get them safely back home to region 4. NCS were lined up on 2 hour shifts, and a pool of 12 were scheduled to make sure each day was covered in every 2 hour slot with a minimum of operator fatigue. One member was appointed to gather status reports on the deployed teams and report up the chain of command Weather conditions were constantly given directly to the teams via voice to advise them what they were traveling into, as Gustav was leaving and they were traveling into the edges of the affected area. NVIS can be achieves with two 102 whips, one front and one back, joined in the center over the vehicle, but it is better to have a support team, trained and ready, to understand propagation, MUF, general band conditions and be in emergency net operation with as many members as possible making every attempt possible to shut and listen. The net can periodically be extended by NCS (Net Control Station) calling for only stations with Good Readable to Loud and Clear copy on NCS, and in turn having them make the same call to determine the relay path. An accurate region roster and some idea of geography helps NCS to determine effectives of net and who to use for relay from deployed team members, if NCS does not have directly copy. NCS always chooses an alternate NCS, the furthest distance possible with reliable copy. This allows them to work together and achieve the broadest working net, with just 2 members to start and direct the net. The net is closed at the end of the 2 hours, and a new net is established with each oncoming NCS, which allows maintenance of the most accurate net roster. One member is appointed to track weather conditions in the path of the deployed teams, as radio station coverage is minimal at best from local broadcast stations, Major media resources are monitored to keep abreast of the fuel and power situation along the route. Having plenty of fuel in the ground is no good if the station has no electricity to pump it out of the ground. An open fuel station may clog one lane of a 4 lane divided highway as vehicles line up for miles to exit and refuel. The deployed members need to be in the proper lane, before the traffic snarl happens. They also need to be in touch with federal resources in convoy to keep them abreast, as the federal response may not be as well organized. Cellular coverage is monitored. MCS and ANCS use Skype to coordinate the net via text chat. Deployed members use Echolink where cellular coverage allows use of their air card for wireless access to an ISP. Winlink is used via aircard telnet/internet connectivity to direct messages to a single or group address, giving a little privacy if they are the first to arrive to a delicate situation and wish not to be in the clear with their Sitrep.. SHARES stations are active in the net, or on standby for direct access to federal entities. Phone Patch operators are on hand, ready to provide first access into a developing situation that may involve hazmat, mass casualty, etc. While traveling, something like a TS-2000 in cross band mode could give all members of a amateur caravan access to the HF net, if each member had something useful to report; otherwise, VHF from car to car, and one vehicle contained the team leader from each deployment group to relay the Intel back into the net for distribution.

RE: [digitalradio] Re: How Can We Push HF Emcomm Messages to the Field?
We get quite good results in the 45 to 50 mile range using VHF SSB (2M) and 5 watts with Olivia from fixed location to fixed location and low gain omni vertical antennas. From a mobile to a fixed location, I would estimate as good a signal on SSB as can be expected from the same mobile to a repeater input on FM; unless there is a tremendous height difference to offset the signal to noise gain of the SSB transmission.

And further, this thought should be considered as VHF FM, or VHF SSB? In a base/mobile or mobile/mobile environment, SSB on VHF works over much greater distances. With voice communications, VHF SSB benefits from having flutter resulting in the desired signal amplitude going up and down, while the background noise level is held pretty constant, by the AGC in the receiver. FM is opposite in that regard - when the signal gets weak, the background noise level comes up, at least until the squelch closes. In my perception, I seem to be better able to fill in the gaps in syllables when the signal drops out, than when it's filled with noise. VHF SSB also has the benefit of probably not requiring the mobile station to have to take time to set up an antenna. If the mobile station is parked in a null, chances are that moving the vehicle a few inches will change a multipath situation enough to provide good copy. If there's benefit to be had by setting up a portable (v.s. mobile) antenna, putting a VHF omnidirectional stick up 10-20' is a pretty trivial task. While there can be benefit to be had by using horizontal antennas, unless you're into serious weak-signal work, it's not necessary to realize large gains in coverage, even using omni antennas on both ends, using SSB. Digital modes that are designed to work well in weak signal circumstances on HF SSB rigs will similarly work well on weal signal VHF SSB rigs, because the same linear-mode technology is involved. Probably the biggest caveat to that will be frequency accuracy and stability. Radios on a net will need to be well warmed up, or have high stability oscillators, if they are operating unattended, and expected to be able to be received by the sender. I've encouraged those that are working on upgrading our regional hospital network to use the IC-706's that they already have set up for HF pactor, to try VHF pactor using the SSB mode, as a way to gain from the more readily available spectrum, so they don't have to compete for access to the very few frequencies available on HF for digital operations. It'll be interesting to see how they do. 73, Bob, KD7NM -Original Message- From: digitalradio@ mailto:digitalradio%40yahoogroups.com yahoogroups.com [mailto:digitalradio@ mailto:digitalradio%40yahoogroups.com yahoogroups.com] On Behalf Of Howard Z.

According to HFN International ALE Coordinator Bonnie Crystal, KQ6XA, the main purpose of the Network is to provide efficient emergency and disaster relief communications to remote areas of the world. Beginning with a core group of six North American radio operators in June 2007, HFN rapidly expanded to cover large areas of the planet with 24/7 digital communications, she said.HFN was designed to be an open framework for global Amateur Radio emergency services to interoperate on HF using the Automatic Link Establishment (ALE) system. Relying on ionospheric radio communications, interconnected HFN base stations scan the radio bands every 10 seconds, from 3.5 MHz-28.0 MHz. Through this Net, Crystal said, ham operators stay connected with each other at all hours of the day or night in any mode of operation, and can send Internet e-mail or cell phone mobile text messages from the field.

Re: [digitalradio] Does an NTS Digital Net Station run 24/7 allband HF?
Bonnie, NTSD is complementary to the traditional NTS structure and interfaces with it on all the NTS structure levels. It is administered through the NTS structure at area level by Area Digital Coordinators each reporting to the NTS Area Chairperson. NTSD automated stations are one transmitter scanning the indicated HF bands. Usually some soft of all band antenna is used with automatic antenna tuners. My station is a Kenwood TS-450S, a 135 foot doublet, with a MFJ 993 autotuner Modem is a SCS PTC-IIex. My VHF packet link is a Kantronics KPC-3+ which feeds into my NTS PBBS and the Eastern Flexnet system The majority are using Winlink classic with Winlink classic scanner software. This is an older piece of software originally developed as APLINK (AMTOR and packet) by many of the same authors who later developed Winlink 2000 and can be run on a very modest computer. For instance I am using a Pentium 166 MHz computer and Windows 98SE. Some stations are running Winlink 2000 and some are using Airmail. Again the majority have multiple Pactor mode capability using the SCS modems. A couple of the automated stations are Pactor 1 only typically using a PK-232MBX, not everyone can afford a SCS modem... We do have an equipment bank with Pactor 1 capable Pk-232MBXs to bring a new station on the line, as other stations leave or lose interest... Most who come into our ranks eventually upgrade to a SCS modem, at least two operators in the past two years You may get a fuller look at NTSD operation from this web page http://home.earthlink.net/~bscottmd/n_t_s_d.htmthe stations and frequencies may not be exacly up to date but it wil give you an idea Most of the participants in NTSD are Digital Relay Stations manually connecting into the various automated systems. Copied into this message are the operators of the Eastern area MBO stations, our ARRL contact, Steve Ewald WV1X, and Dave Knight W4ZJY, and George Thomas K7BDU, the Digital Area Coordinators for Central and Pacific area NTSD, respectively Marcia, KW1U in addition to being a MBO is also the Chair of Eastern Area NTS staff. Hope that answers your questions... As I noted before, my original comment was not to be little HFLink ALE operations, just trying to let you know we are still out there after all this time. 73 Dave WB2FTX Eastern Area Digital Coordinator- NTS Digital - Original Message - From: expeditionradio To: digitalradio@yahoogroups.com Sent: Sunday, November 23, 2008 12:09 PM Subject: [digitalradio] Does an NTS Digital Net Station run 24/7 allband HF? Hi Dave WB2FTX, Does a station in the NTS Digital net operate 24/7 on all HF bands simultaneously? Does a typical station in the NTS Digital net use 8 transceivers to achieve simultaneous operation on the 8 HF bands 80m/40m/30m/20m/17m/15m/12m/10m? Or, does each NTS Digital station scan every HF band? What type of software/hardware does a typical NTS Digital station use to achieve allband 24/7 HF operation? I'm very curious about it, because none of the publicly available information by NTS indicates that any station in the net is running 24/7 allband HF.

RE: [digitalradio] Global traffic and emergencies
Another example of why ARRL turned over all long distance (HF) emergency communications to the MARS organizations and agreed that Hams were to provide only last mile (VHF/UHF) emergency communications. The Ham community showed their distaste for P3, so it has been largely moved to NTIA frequencies. Unfortunately, it set the stage for loss of confidence in the Amateur Community for Emergency Communications over a long range, unless they are self-funding the entire response.. There still are some RMS Pactor stations on the Ham spectrum, and some using P3 for Keyboard to Keyboard use. Most of them are candidates for MARS service as they continue to get the flack from the contesters. Everyone eventually gets whet they want. Some are late to realize that what they got in return wasn't actually what they wanted...

Re: [digitalradio] Re: [illinoisdigitalham] Re: [psk31] Global Emergency Network Marks Record
At this point in time most of the traffic is ham to ham. like welcome to ham radio, your license is about to expire, welcome to a new ham club (group of hams) etc..Some of these are also confirmation of messages received, birthday greetings and the like... This ia a free public service sponsored by NTS and the ARRL and if fact was one of the first ham related activities... The relay in American Radio RELAY League (ARRL) refers to this aspect of the hobby. There still are the messages to the general public. In the times of communication emergencies (which is the prime reason for the existence of NTS) there are many health and welfare related messagesMany of these cannot be handled or delivered by any other means when the infrastructure supporting , the traditional phone system, cell phones and email disappears...The routine messages are a way of keeping the skills of trained operators honed or oiled if you will, to respond in a structured fashion in an emergency or disaster without giving it a second thought... It becomes part of your operating skills. Amateur Radio -When all else fails. Individual stations operating without any infrastructure but within a structured system, on emergency power, if necessary, have always been the hallmark of ham radio. Note, that what I have been discussing is the digital aspect of NTS... Similar activites as well as traffic volume exists within the traditional NTS systems. NTS Digital is only a complementary system to traditional NTS and interfaces with it at all levels of NTS structure, from Transcontential Corps (TCC) to area, region, section and local.. Indeed the automated portion of NTS Digital would not be successfull without these links to the traditional NTS operator structure 73 Dave WB2FTX - Original Message - From: Howard Brown To: digitalradio@yahoogroups.com Sent: Sunday, November 23, 2008 2:19 PM Subject: Re: [digitalradio] Re: [illinoisdigitalham] Re: [psk31] Global Emergency Network Marks Record Hello David, I would like to ask what type of traffic is involved in the messages you mentioned (10,000 messages in Oct 2008).

Re: [digitalradio] Global traffic and emergencies
David, You have your opinion I call tell you that NTS and NTSD is going stong... Last month Eastern Area NTSD handled over 10,000 messages Regarding the distaste for P3, it is a spectrum hog at 2.4 Khz more suited to commerical applications (where there are fixed channels) rather than the narrow bandwidths used in ham radio... Although NTSD for the most part has P3 capability, we still use P1 and preferably P2 which both have a bandwidth of 500 Hz. especially since most of our operation is confined within the automatic control subbands. By the way NTS and NTSD is self funded... We do it for the love of the hobby and public service 73 Dave WB2FTX - Original Message - From: David Little To: digitalradio@yahoogroups.com Sent: Sunday, November 23, 2008 5:47 PM Subject: RE: [digitalradio] Global traffic and emergencies Another example of why ARRL turned over all long distance (HF) emergency communications to the MARS organizations and agreed that Hams were to provide only last mile (VHF/UHF) emergency communications.
