In attended operation, Pactor III is a bit challenging in that one must ensure that one's modem does not dynamically expand its bandwidth to exploit improved conditions unless the full bandwidth is clear of other QSOs. But as long as operators fulfill their responsibilities, Pactor III should not be any more problematic than any other digital mode. 73, Dave, AA6YQ Hi Dave, This is just about the 1st time you spoke rationally and we agree. Now you are not mixing up PACTOR I/II/III with Winlink2000 and this is a start. I would also like to let you know that PACTOR operators who intend to operate in PACTOR III mode, start their QSO with the 2.4 KHZ filter in their radio and they are able to hear all the passband that PACTOR III will eventually occupy when expanded. Hence they can hear anyone else using the frequency. If they want to use PACTOR II they always use their 500 HZ wide filter and they still can hear if anyone else is using the frequency in their passband. So PACTOR III operators never interfere anyone else's QSO because they can hear them before transmitting. Automatic or semiautomatic Winlink2000 PMBOs and other automatic FORWARDING and not FORWARDING HF Mailboxes, HF to VHF/UHF GATEWAYS etc. using PACTOR/PACKET or any other modes, work in a different way and I am not going to go back to it because this matter has been beaten to death already. People get sick of hearing about it all the time. 73 de Demetre SV1UY

A common ploy in the business world. Looking at the new systems, I'm sure they will find their users and devotees, but, to be honest, I'm not sure that they will catch on in the UK, or even most of Europe, to a great extent. The obvious rival is internet email. Love it or hate it, and argue that it's not using Amateur Radio all you like, and that it could be knocked out by accidents and any number of causes, but it's just too cheap, too fast and, mostly, too reliable to send stuff over the air instead. Add to that the need to dedicate radios and antennas to it to make it work, which was why I did not run a BBS or an APRS node, as I prefer the freedom to use my own antennas whenever I wanted, and the added problems of not wanting to loose a band due to having a transmitter going on a nearby frequency for periods of the day, and it might seem selfish but I wasn't prepared to do that. All cudos to those that did, and paid out to put node transceivers on towers etc., etc. but it takes alot of organising to do it... There will always be the special interest groups, who will do it because they want to prove it can be done and those that live in places where sending email is expensive, or difficult, of course. However, as Amateurs, it seems to me that we do seem to keep coming out with new ideas to reinvent the wheel at times. Dave (G0DJA) Hi Dave, Wise words OM. I have also seen the UK packet network first hand since I am in the UK at least twice a year for a period of 2-3 weeks each time and I know what you are talking about. Also in the UK once the aerial masts were sold to private companies many PACKET NODES died as well, as well as many voice repeater nodes. As for the Internet being the biggest competitor to PACKET RADIO and the like, yes it is the biggest competitor, but ostly radio hams got sick of the NETROM BARONS and PACKET KINGS, hi hi hi!!! I personally still like PACKET Radio and I still maintain a 19k2 link and 9k6 and 1k2 user ports along with an APRS IGATE and DIGI here in Athens. A few people still use the PACKET RADIO nodes but not many. I also use my mobile phone as a GPRS modem connected to my laptop and this does not cost me more than 3.5 EURO a month. Also my PDA when there is free WiFi access in the city since the PDA is always in my pocket. I use these when I want to surf the Internet and I am away from any fast Internet at home, but when I have radio access I like to use 9k6 or 1k2 PACKET RADIO for my Ham stuff, or my SCS-PTCII modem for PACTOR/PACKET/RTTY/PSK31 QSOs or HF radio e-mail especially when I am on holiday and I can get all the necessary rigs with me. After all I enjoy using my radio gear more than the real Internet, especially when I am away from home and away from my ADSL or WiFi backup link. Mind you people in France and Germany and Switzerland have a marvelous PACKET RADIO NETWORK and they have upgraded to 76k8 long ago so PACKET RADIO is not DEAD in Europe. I think the Germans especially and the French have done a marvelous job in PACKET RADIO NETWORK in their countries. They do not care about Internet taking over, they just try to maintain and improve their network constantly. It is not a coincidence that SCS is a German company. Also FLEXNET and DAMA are both made by German Hams and FPAC by the French Hams. These 3 are the best Network Switching Protocols in Packet Radio. So really if we are to improve our hobby and more than anything else digital modes that we all seem to care about, we should perhaps take some lessons from these guys in Germany, France, Switzerland and also in Holland where they also still have a decent Packet Network as I read in various Radio Amateur lists. I am sure that some radio amateurs that live in these places and are also members of this list can tell us much more than I said. We can definatelly take some lessons from them. 73 de Demetre SV1UY

Don't forget that a British software writer (G4BMK) managed to implement PACTOR 1 properly using a terminal unit, not a sound card, and in a DOS computer (I have bought his program BMKmulti and it works as good as SCS's PACTOR 1 implementation). This is probably the reason why SCS decided to keep to themselves PACTOR 2 and 3 and not to license it to anyone, although I am not sure if anyone ever asked for a license of PACTOR 2 and 3 following ther failure to implement PACTOR 1. If the best companies could not implement properly PACTOR 1 can you imagine what a mess they would do with PACTOR 2, never mind 3. So I cannot see why some fellow amateurs complain against SCS keeping their code to themselves. They do not do the same with other software writers. I dare and urge the software writers if they are any good to try and contact SCS and ask if they can implement PACTOR 2 and 3. It would be great if they could offer the efficiency of PACTOR 2 even in a soundcard program, but I think they can't. If SCS is such a bad company and they will not license PACTOR 2 or 3 (and I personally do not blame them for doing so) why can't they try and write an ARQ SOundcard Program that can go as fast as even PACTOR 2? Never mind PACTOR 3, which many people class as a commercial product! At the moment I can only see PSKmail that performs only as good as PACTOR 1, thanks to Per PA0R, which is better than nothing at all. Also I saw lately NBEMS trying to do the same as PSKmail although I like PSKmail much more than NBEMS. Both can be called The poor man's Winlink2000, but really they leave a lot to be desired as far as speed and good behaviour in bad HF propagation is concerned. 73 de Demetre SV1UY

But it is not necessary to do this as long as the relationship (the shift) remains proper at 170 Hz for most cases, and with the mark tone high, as it relates to FSK. With AFSK and using a different sideband things are a bit reversed, but as I mentioned earlier, the programmers have mostly standardized on leaving the rig on USB if using AFSK and they make the tones work correctly as if you were actually transmitting FSK with mark high. 73, Rick, KV9U Sure Rick, But people should know what happened in the past, otherwise they use a soundcard mode today with their 2.4 KHZ SSB filter and they expect all the filtering to be done from the soundcard, which is impossible due to the AGC effect. Some even use the 2.4 KHZ filter to copy 20 PSK31 stations and then they complain about adjacent interference!!! Really if one wants to have a decent QSO he/she must use a marrow filter and of course must know a bit of history and how to use such a narrow filter. I think the worst thing that ever happened to digital programs was the ability to move your cursor along the waterfall and think that anyone else with a stronger signal is QRMing your QSO!!! Maybe because nobody has ever bothered to tell the newer hams how did RTTY used to be in the past. And don't forget that really it does not matter if you use USB or LSB and you can always flick the REVERSE SWITCH. This is true for all narrow digital modes with the exception of QPSK31. In spread spectrum modes only, it is important for everybody to use the same sideband, i.e. for PACTOR 3 everybody uses USB.

Zack Hi Zak, For RTTY whoever uses the American Tones (Mark 2125Hz - Space 2295Hz) always uses LSB, whereus if you used the European Tones (Space 1275Hz - Mark 1445Hz) you have to use USB so that the 2 systems are compatible to each other. All my old homemade terminal units were using the European Tones so I always used USB. I always favoured the European Tones because they were chosen more wisely to be in the center of the passband of the crystal filter of the old transceivers that only had an SSB crystal filter and also because I liked to listen to the sound around 1360 Hz (the center of the European Tones) while tuning and and afterwards during the QSO. It is a more natural sound to me. Whenever I heard the higher tones that the american terminal units used, I always ended up with a headache. Of course f you did not follow this norm, you could always switch your tones the other way around with the REVERSE SWITCH that all terminals used to have incase someone was not using the correct combination. Is you notice at the tones I described in the first paragraph, the Americans tones are Mark-Space where the Europeans always are Space-Mark. Now with the soundcard programs usually they tell you to use 1500 HZ as a center frequency and use USB. Of course if everybody follows this protocol there is no problem. Some soundcard programs have a SOFTWARE REVERSE SWITCH so that you can change it in case there is any incompatibility in the tone pairs. 73 de Demetre SV1UY

I have simply pointed out, as have others, that Winlink and Pactor stations do not listen before transmitting, unlike essentially the entire rest of the amateur community. Since the Winlink/Pactor people acknowledge the truth of this point, Well we have said that many times, Winlink-2000 clients ALWAYS listen before transmission, and PMBOs never talk to other PMBOs like other automatic systems do, just because Winlink-2000 PACTOR PMBOS are semi-automatic. If the hidden transmitter syndrome exists in some cases, the file transfer that they will do is very fast because they use PACTOR 3 and very soon the frequency will be clear again. Not a big problem. Other system sit there for hours making MAIL FORWARDING but you never complain about them. Other send LONG BEACONS without listening first but you have never complained.

If SCS actually fully licensed the mode, it would seem to me that they would insure that the memory ARQ would have been included. Only the SCS modems seemed to have this feature. That is why they worked better between SCS modems than between other manufacturers products, even between the SCS modem and other manufacturers. Hi Rick, Well my old KAM Controller with it's addon PCB for supporting PACTOR 1 definatelly has Memory ARQ. Memory ARQ is a must for PACTOR protocol. There is no PACTOR without memory ARQ. That is the main reason why PACTOR is a QRP mode!!! Especially with PACTOR 2 people have managed to access a mailbox in Germany from a mobile station in Australia on 20 meters, a short mobile aerial and only 16 mWatts of power. Some QRM they would cause to the other spectrum users! hi hi hi!!! As for licensing yes it was licensed. I do not think that any serious american company does reverse engineering. For quite some time my main software/hardware mix was an AEA CP-1 with BMKMulti. Crude by today's standards but worked well for RTTY, CW, AMTOR. Instead of upgrading when he added Pactor, I unfortunately sold all my digital equipment to buy the HAL P-38 modem which turned out to be a complete disaster. The HAL P mode (an attempt to simulate the Pactor mode) was pathetic with dropping what appeared to be a solid link, etc. They tried many software updates, but nothing improved. Pity you sold it because BMKmulti performs as good as an SCS Modem in PACTOR 1 Rick. Clover II, which was a nice mode, could not work deep into the noise and so was very limited. Even when I used to try and chat with Ray Petit, W7GHM, the inventor of CCW, Clover and Clover II, with marginal link conditions, Clover II would rarely work well. If we had had PSK31, MFSK16, FAE400, etc. like we do today, our chats would have been fine as signals were clearly copyable by ear. Well as you see in todays modes, nothing comes close to PACTOR-2 never mind PACTOR-3's performance. Not even the military modes because with a little noise they lose the link. They cannot be FAST and ROBUST like PACTOR-3. The military ones also need more than 3 KHZ bandwidth. Only perhaps PSKmail and FLARQ HF Radio e-mail Systems are getting there slowly, but their speed leaves a lot to be desired. The best they can do at the moment is perhaps 200 bps using PSK-250, which is the same as PACTOR-1, whereus PACTOR-2 can go up to 800 bps and more with realtime compression. I wouldn't even dare comparing PSKmail's PSK250 with PACTOR-3! Their next step would be PSK-500?? if there is such a beast. Also there is still no memory ARQ built in these systems, unless if this has changed by now. Anyway PSKmail has quite a few followers in USA and I hope it will have more because it is a soundcard mode and anyone can get on it very easily. That will not keep the anti semi-automatic guys happy, but such is life I'm afraid. This is one more reason for everybody to complain against RM-11392 petition to your FCC.

You know, Demetre, I am getting tired of remarks like that from you. I have attempted to reply to your posts with courtesy, but you seem bent upon returning courtesy with bad manners. Please stop that. In actual fact, I **own** a KAM unit. Used it for GTOR. It was horrible for Pactor 1 in my opinion; quite inferior to my old PK232 (my first TNC) and in no way comparable to the SCS PTC-II which I also used to own. GTOR was very unreliable, and is utterly dead and gone. Someone else on this forum has corrected my statement that the KAM units lacked memory-arq. OK, fine. My experience with the unit, as I mentioned above, was that they were buggy and did not do well for Pactor. As for reverse engineering, I do not know about that, but if they did that, this is one more reason for the failure of their product. I know that SCS did license PACTOR 1 though Actually, the only outfit they licensed it to was one American company the name of which escapes me. They were not a business success, and I think they were actually just selling re-labelled SCS modems rather than different modems using licensed Pactor protocol. I do not believe that any amateur radio manufacturer ever succeeded in negotiating a straight license with SCS for Pactor. This leads to the inference that SCS wants to sell hardware, not merely enjoy licensing fees. I may be mistaken about that, but that is not an unreasonable deduction. de Roger W6VZV Sorry if I made you upset Roger, but you insist on something you do not know very well and always try to prove that the other guy is wrong.

On the issue of AEA licensing Pactor from SCS, no, I don't believe that ever happened.

HAL did the same thing. So did Kantronics. This reverse-engineering led to some pretty lousy Pactor 1 QSOs, (incompatible protocols and poor hardware) and that is also why no TNC other than an SCS TNC could support Pactor II.

You just boot in your Windows OS and then run his Linux emulator as a Windows program where you can run PSKmail. Up to now they use PSK-250 and there are already a few experimental American servers online. This is a freeware soundcard program and I think it has the potential of reaching PACTOR-2 in a few years according to the pace they are going. Don't forget that really it is a one man's job and he gets nothing out of it, so it is marvelous what he has done, and more marvelous that he allows anyone to touch his code. Per PA0R is probably more interested in seen PSKmail progressing than his own personal glory. He is a true Radio Ham. This is unlike other code writers who although they allow everyone to use their program, they keep their code to themselves. Of course it is everyone's right to protect their code and I do not blame anyone here, I am just stating a fact. 73 de Demetre SV1UY

No one is defending W1AW or the other practices that involve transmitting without listening. I happen to think that all such practices are morally wrong and legally questionable. Regrettably, the FCC has already said that W1AW can get away with its broadcasts. A bad call, but there you are. 2. Pactor is far more ubiquitous in its transmit-without-listening practices than anything else on the air. The Pactor community flatly refuses to change its practices, and they routinely QRM innocent QSOs with impunity and indifference. Mark's superb petition will help curb this. 3. I sold my SCS modem because Pactor as a Keyboard-to-Keyboard mode is as dead as Julius Caesar. No matter what a few outliers may say, Pactor is dead as far as ordinary ham radio goes. It is now solely a mailbox mode, used mainly to provide cheap, inefficient internet service to those who are not able to hook up to the usual internet grid. Doesn't sound much like ham radio to me. Other commercial services are a better provider of this capability--it is not appropriate for amateur radio. 4. I am a yachtsman myself. I can attest that very few yachtsman use amateur radio, let alone Pactor, for even a tertiary communications system when at sea. 5. Winlink is largely irrelevant to emergency communications, propaganda to the contrary. Having operated emergency communications in numerous fires and earthquakes, I can attest that Winlink was never a resource. The simplest modes, i.e. FM and SSB, provided the bulk of amateur-supplied communications. Simpler is better. de Roger W6VZV Fine Roger, You have your opinion and I have mine. Now if you can't be bothered to look for PACTOR keyboard to keyboard QSOS this is your problem not mine. When I look I can always find some. As for Winlink not been an emergency resource, I have read and still read otherwise in the radio amateur literature around the world. It has help in numerous cases in your country and in the tsunami that hit the Indian Ocean a few years ago at Christmas and if this humanitarian reason for Winlink's existance is not enough for you then I do not know what more to tell you. But it does not stop there, it can also provide free Internet e-mail for the Radio ham on the move globally (from the open seas to the bush of Australia, to the jungles of Africa, in Asia, in South and Central America and in many other parts of the civilized world, as we all like to call our western world today) and at the moment it is the only system that has a global network on HF and this is a great help for places with no communications infrastructure. So Winlink is not only for emergency communications, although it can be a big help in emergencies where FM/SSB and all bla bla modes cannot really help, except perhaps when you want to coordinate the fire fighters or other cases where accurate contain transfer is not necessary. If you just want to spoil a Great Radio Amateur Global Communication System just because sometimes af few ,ignorant perhaps, of it's users spoil your SSB QSO then go ahead and do it. This is supposed to be a free world but in a free world we should always be a bit more tolerant, don't you think? 73 de Demetre SV1UY P.S. as for automatic operations, don't forget that it is not only Winlink2000 and W1AW who do that. There are also PACKET BBSes (the real Robots where both ends have no human operator, the have Martians, there are Propnet stations, Beacons of all sorts, APRS DIGIS and many SSTV repeaters, PSKMAIL Mboxes, just to name a few, so if you tolerate their operation PLEASE do not complain about Winlink2000.

It is easy to understand how this can happen on 20m where many use directional beam antennas. The local station does not even have to very local to the PMBO, but beaming in its direction for his QSO with a station in the direction of the PMBO, so that the client is off the side of the beam pattern. An operator at the PMBO could easily detect the beaming station, perhaps even over S9, but the client, being off the side of the beam, detects nothing and thinks the frequency is clear. This is critical to the problem of understanding how unattended stations can mix with attended stations on shared bands, and your explanation would be very much appreciated! Thanks in advance, Skip KH6TY Hi Skip, I am quoting here my reply to DAVE about his Anti-radiation missiles tuned to PACTOR PMBO frequencies for your information! That shows you exactly the attitude of some people against anything they dislike and how they act. If the Pactor PMBOs activated any DCD mechanism, people like Dave would sit there all day to deliberately cause QRM with their Anti-Radiation missiles tuned to the PACTOR PMBO frequencies, as he said, and cause havoc. Is this kind of QRM accepted by you? What about this Skip? Is this justified? Tell me what works perfectly on HF and if we manage to correct them all then PACTOR will follow and I believe the PMBOs will have no problem finding a way to implement a DCD mechanism. And just like Andy, our moderator, said previously: - Aside from Pactor, I suspect that many ALE operations are not always under full manual control. Neither are some Propnet stations that use 300 baud packet or PSK31. Many DXpeditions act like they can transmit any place they want, and then there are also the folks at W1AW who send old news automatically at predetermined times via RTTY and CW. -- And I must add, what about the numerous nets on HF that deliberately cause QRM when anyone dares to use their frequency before they start their NET? What about AX25 BBS FORWARDING that still takes place on HF? (These are really the automatic ROBOTS, not the semi-automatic PACTOR PMBOs), what about HF APRS Digis?

This argument is completely bogus - just another rationalization for continuing to generate QRM. While a few operators might QRM a few PMBOs for a few days, the effect would be minimal.

[digitalradio] Interesting article from STXARES
This is what I fished yesterday. I dedicate it to this list. == From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Sent: Friday, October 19, 2007 04:59 To: [EMAIL PROTECTED] Subject: [STXARES] Why Is a PIO Important? Posted by: Bill Rimmer [EMAIL PROTECTED] n5lyg1 Thu Oct 18, 2007 6:38 am (PST) Allen G Pitts, W1AGP ARRL Media PR Manager During the month of September 2007, there were many positive articles in the media about Amateur Radio. But, there were also a few which did major damage to the public perception of our Service. Unfortunately they were in large metropolitan newspapers and, by the time an ARRL PIO learned about them, it was too late to change things. These articles were proclaiming the death of Amateur Radio, that it was antique and an anachronism to the 21st century, full of ancient grumpy men and that the hams themselves were not friendly nor welcoming. The real tragedy of this is that the reporters were quoting their community's own local hams! None of the articles had numbers or empirical data to show the true trends underlying the present state of amateur radio. None looked beyond the personal opinions voiced by their local club or they might see the recent gains following February 2007. None of them saw the larger picture around the country or the work being done in schools, scouting, ARISS, digital work, ARES and other EmComm actions. But they had their quotes, and that was enough to hurt us. While not all areas of the country are motivated by the same approaches, there really is a lot of new growth in important areas. In some places, emergency operations and EmComm is indeed a BIG deal. We are gaining many new hams entering the field because they want to be part of a response operation. That is part of this year's PR push on EmComm. In other areas, it may not be EmComm that is the big draw. It could be the hobby side of the Service. For them, the Hello! materials are still available and timely. If that fits your area, then use them there. In some other places or situations, it will be the technical side of Amateur Radio that is of interest. The ARRL is working on a coordinated program for that to come out in 2008. It will be the hardest of the three to create, but plans are already well along. These three, Hobby, EmComm and Technical activities are the motivational keystones of the Service. No one thing is going to attract the general population. We encourage you to look at your own local situation. Which type of motivator works best in your area? Use that one. In the meantime, our importance in EmComm is a motivator in antenna issues, spectrum defense and other political situations. Are we dying out? Not really. Amateur Radio never was, nor will be, a mainstream activity. But recent numbers are up and, just as important, the percentage of hams who actually get on the air or go on to higher class licenses is up. With the 10 year license-lag, most who are dropping out seem never to have been active to begin with. We also see trends which follow the solar cycles -- currently at a low. To quote Pogo, We have met the enemy and he is us. Over the past two months the national PR Committee has seen far too many articles quoting their local hams saying we are all dying out! With attitudes like that, is it any wonder the reporters print it? It's a self-fulfilling prophecy. This is why we need informed, active PIOs and hams need to defer media responses to them. Anytime you or a ham in your area is contacted by the media, steer them to your local PIO. If you don't have one nearby, steer them to your section's PIC. These professionals are trained in showing the best that amateur radio has to offer to the public and to prospective licensees. Fifteen minutes of individual fame is not worth the damage your personal opinions could cause to us all.

[digitalradio] Re: Imitating the big guys
--- In digitalradio@yahoogroups.com, Dave Bernstein [EMAIL PROTECTED] AA6YQ comments below There are some who claim that email messages should not be conveyed by amateurs because doing so would compete with commerical operations, but the same could be said of any QSO. I don't believe there's any merit to this claim. I don't see the point of you mentioning it then. The allegation that WinLink 2000 is illegal, at least in the US, is based on the fact that its PMBOs transmit without first verifying that their frequency is not in use. This is a clear violation of 97.101(d), which states No amateur operator shall willfully or maliciously interfere with or cause interference to any radio communication or signal. A PMBO's transmission is not malicious, but its definitely willful. Again this is an old horse already beaten to death many times, but you keep coming back at it over and over. Any interference caused in Winlink2000's semi-automatic operations is not the PMBO's fault but the initiator's fault who is responsible for any QRM because he has to listen for a while before he transmits, and he should also keep listening when in session with the PMBO. Myself and many others do this i n every session, even when in QSO using PSK31. Whoever does not do this does not follow good radio amateur practices, full stop. Automatic operation is only what F6FBB BBSes do in PACKET radio when they start MAIL FORWARDING. Winlink2000 PMBOs use only the Internet for exchanging traffic among them. Winlink2000 PMBOs don't even transmit beacons on HF every so often, like other systems do on HF. They only respond if and when they are called by a client and the client is responsible for the QRM they cause. So any claims that they cause willful interference is not true. 73, Dave, AA6YQ 73 de Demetre SV1UY

Is it a thousand dollars superior to Olivia or MT63? Will I be able to have reliable QSOs where other modes fail ? -- Andy K3UK www.obriensweb.com Hi Andy, It depends what you want to do with it. For $1000 you get a very good modem that allows you to do digital filetransfers on HF up to 5200 bps when conditions are good, but still manage to keep the link when conditions are lousy, without having to revert to other modes and most important of all, filetransfers will be ERROR FREE because it uses ARQ. Not a single character will be transfered erroneous. You can also use it for picture transfer (with a free part of the program SIMPLE) that works in a way that SSTV works, but in PACTOR 3 mode. Of course you can make error free QSOS with other PACTOR users (1, 2, 3) but you will not find many on the air these days, much less than PSK31 and RTTY users anyway. Here in Europe I occasionally hit someone calling CQ on PACTOR but not very often and this might be due to it's price (600 EUR) in Europe for a PACTOR 2 SCS-PTCIIex modem, the cheapest of it's series. You need another 170 EUROS for the PACTOR 3 license. Or perhaps because of the flamewars against Winlink2000 and consequently against PACTOR because people tend to think that PACTOR is WINLINK2000 because there is a lot of misinformation on the net against PACTOR and against WINLINK2000. You also get superior PSK31, AMTOR, RTTY, 9k6 and 1k2 PACKET and NAVTEX capability by using a free terminal program or a more sophisticated but still freeware called NCWINPTC. You also get FAX but I think you must bye a program (shareware for around 50 EUROS). All the above modes, except FAX I use at least once a week and they work better than the equivalent soundcard modes. You even get analogue SSTV (but you also have to pay an extra 60 EUROs for JVcomm32 and I am not impressed with it for SSTV with the SCS-MODEM). For SSTV I use a soundcard program called ChromaPIX which according to many SSTVers is the best soundcard SSTV program. It gives you the best SSTV reception but again as many good things in this life it costs 120 dollars. So if I were you and the above description covers you I would buy an SCS-modem.

And coincidentally, mine rarely goes to 3600, usually the highest speed attained is 2700. Jose, CO2JA Hi Jose, Those were the days Jose, when we had to make our own TERMINAL UNITS for RTTY. I really started on RTTY in 1984 with my ZX-81 personal computer, G4IDE RTTY EPROM, a Homemade Terminal Unit, an 81 LED Matrix as an RTTY TUNING SCOPE where I could see the MARK and SPACE TUNING CROSS, a GREEN MONITOR and my Homemade 5 watts SSB transmitter with a YAESU FRG-7700 receiver. The aerials (20-10 meters 2 element CUBICAL QUAD and 80-10 dipole) were homemade too. I made thousands of QSOs this way. After a few years I made a better TERMINAL UNIT and used my DOS computer with the BMK-Multi program (by G4BMK) which supported RTTY, AMTOR and PACTOR 1. They used to call it PACTOR these days. Great setup. Had many QSOs with it. I still have the above TERMINAL UNITS, ZX-81, and DOS PC. Then in 1998 I got a PTC-II and shortly after a PTC-IIe for my portable HF operations. I use my PTC-IIe with my FT-817 or RACAL PRM- 4031 or FT897D. I use PLUSTERM 2.3 and a small DOS palmtop HP-200LX with my PTC-IIe and FT-817 or RACAL when I go for a mountain hike. Extremely light setup. The PTC-IIe controller in PACTOR mode keeps me in QSO even when I cannot hear the other guy's tones and error free because of the ARQ and really flies when I have good signals. I am extremely happy with the way PACTOR 2 3 operate and also with all the other modes my 2 PTC-II controllers support, being RTTY, PSK31, AMTOR, PACTOR, NAVTEX, FAX, SSTV. I can even exchange DIGITAL SSTV pictures in PACTOR 3 mode and error free. Of course I also like SSTV (I'm not mad about DXing and card collecting) and I have built my own Hardware SSTV controller, not with a P7 cathode ray tube but with TTLs, RAMS, etc, but this is analogue SSTV and I am not sure if it is in topic with this group since analogue SSTV is not a digital mode, despite of what other might say.

You seem to forget that radio amateurs should show some courtesy. It doesn't hurt you know. This is the most important aspect of Amateur Radio, at least this is what I was taught when I sat for my Radio Amateur Examination in this country. We all like to do our hobby, if you are only interested to bully people and not get on the air, it's your choice, but reverting in name calling will never resolve the busy detector issue, nor will it stop Winlink, ale or whatever you see as threatening you! You need to talk , have an open mind and try to convince the other guy with facts and not by telling him/her to medicate. Perhaps you need that. Because you hate seen messaging systems (semiautomatic) on HF does not give you the right to stop others using them. If you want to have a constructive discussion by all means you are welcome, but name calling is no good. It has a negative effect. Back to digital amateur radio now. 73 de Demetre SV1UY

Common sense prevailed (even when a few crazy contesters sometimes attempted to overpower the BBS forwarding, specially on CW and RTTY contests. Nobody even whined about it). Common sense is what seems to have being lost nowadays I'm afraid Jose. As I remember, packet BBS's were not so few. Quite a few could be found between 14090 and 14115, just to remember the 20 meters activity. I have been a BBS sysop using only radio links since 1991 (three FBB/JNOS BBS's and multiband nodes, and cooperated in setting up another three) and operated in several bands in different seasons. Indeed a big portion of 20m digital subband was full of them. There are still a few around. Jose, CO2JA PS: Doing whatever is interesting, fun or novel in ham radio since 1972. OK Jose, I have been a licensed radio ham since 1983 and an SWL since 1970. Also, hoping this day is not the start of another anti-Winlink rant flood campaign on digitalradio. Please, spare us the undeserved suffering...this is not an appropiate forum for that anti-Winlink whining. Most of us on this list are NOT Winlink 2K MBO operators. It shouldn't start anything since this is really an argument about PACTOR 2 or 3 versus soundcard modes and not about Winlink2000. If anyone wants to argue against Winlink2000, he will start arguing very soon about PSKmail, ALE or any other messaging system that might be developed because they are very similar systems. Arguing against a system one cannot understand, use or does not like, does not promote digital and amateur radio at all. There are many others who want to use messaging systems. After all amateur radio is not only about voice QSOs, RTTY, PSK and all the variants, it has many aspects, many modes and we should all be a bit more tolerant since we are only doing a hobby here and if sometimes we cannot avoid the hidden transmitter syndrome (which by the way does not cause problems all that often) and cause some QRM to each other it is not the end of the world.

If you are serious about digital filetransfer, e-mail networking etc, then PACTOR 3 is the way to go at the moment. If you want Digital QSOs then PSK31 is OK. I use both, but I never call any mode a pest. After all Pactor 3 is in the in wideband portion of the band now. PACTOR 2 is where all the other DIGITAL modes are. RFSM2400 is in the wideband portion of the band too. Is this a Pest too? Is SSTV a pest too? Is DIGSSTV a pest too? Is FAX a pest too? Is Contesting a pest too? Is SSB voice a pest too? Don't tell me about the Winlink Mboxes that do not listen before they transmit because the SCS controllers have the option to listen before transmit. It is the Winlink people that have decided not to use it. 73 de Demetre SV1UY

--- In digitalradio@yahoogroups.com, Rick [EMAIL PROTECTED] wrote: All good points, Demetre, [snip] Thank you for the information on RFSM2400, as many of us suspected that it would require a very good signal to work well. Once you reach a threshold of adequate S/N, it probably works as they claim, but that may be well above zero dB. The need we have is to send ARQ data at moderate speeds above zero dB, say 1000 wpm or so, and yet have a fall back to a 100 wpm or even a bit less as the S/N deteriorates. As we found out the hard way, it is not that easy to get even a 10 dB S/N ratio on HF bands. Many of our communications on HF are below that and are borderline for SSB. But they are good for digital/CW modes down to -15 or so. 73, Rick, KV9U OK Rick, First off PACTOR 3 supports DCD control so it can listen before it transmits. Now maybe the Winlink people have a good reason to have their automatic MBOS not support the DCD control, but the human operator that calls an automatic MBO can listen to the frequency and make sure noone else is using it before he transmits. Also this will make sure that if someone's life is in danger they can reach the autoanswering MBO no matter what. It is not the end of the world if in a rare occassion someone's QSO is ruined if it is for a good cause. Now I can hear you saying that people can abuse this. Well in this case you canreport them to FCC. I think that this is called semi-automatic operation. In the past when we had PACKET FORWARDING taking place, non stop, day and night, noone was complaining. Why was it OK then and it is not OK now? What about all the contesters that transmit wherever they want without even asking if the frequency is on use? Do they own the frequency? PACTOR MBOs and maybe ALE systems are just lurking there and if the frequency is clear and someone calls them they respond. The way I use WINLINK PACTOR MBOs is to first listen for a while, make sure the frequency is not busy and the call. If the frequency is busy I QSY and try to contact another MBO, the same way as before. If all the frequencies that PACTOR MBOs are available are busy then I wait. It is not the end of the world if I do not get through to them straight away. But if my life or someone else's life is in danger, then I will use the most available power and QRM anyone who is in the same frequency. I think this is fair. As for your last comment, I also wish there was a soundcard mode or a system of combined soundcard modes that can do what PACTOR 3 can do. There isn't any though. There isn't any soundcard mode that can do even what PACTOR 2 can do. It is either impossible to develop as a soundcard mode (which is the most likely to be true), or programmers are too lazy to do it (which I don't believe so much), or programmers want to make some money if they ever find the time to develop such a beast. SCAMP is a perfect example of what cannot happen on HF. It was good only when there was no noise. It lost the link at the slightest noise. I followed this experiment all the way until it was abandoned, and I don't believe that WINLINK people are paid agents of SCS 'cause this is a story that has been mentioned as well by ignorant people in many mailing lists. I don't think you do either. In any case I am back to PACTOR 3 any day. I am not wasting my time with PSK in a soundcard because I could be wishing and waiting until 2050 or later, if I'm still alive then! hi hi hi!!! I still like PSK31 for a QSO because this is way to make DX though but not for filetransfers, e-mail etc over HF channels. And remember PACTOR 3 is not WINLINK. Winlink uses PACTOR 3 (it is not the only system that uses it) and if some think that they do not use it correctly, well it is a matter of opinion. Life is too short man, enjoy it while you can. 73 de Demetre SV1UY

I have experienced this myself many times on 20m, and because of its great capability to keep the link, it never give up but squeeze you out. You will have this pitiful meeting with pactor almost all over the digital segment of 20m, from 14.065 to 14.120 with some small gaps.. I have no trouble understanding those who call this a pest. 73 de LA5VNA Steinar Then you can report these stations Steinar. There are lids in every mode. I always listen before I transmit, whether I use CW, SSB, SSTV, PSK31 or PACTOR. Because some PACTOR operators are lids, it does not mean that we are all like that. I can only understand the necessity to transmit without listening only in an emergency situation. This is a hobby and it should be kept like it. Let's all try and educate whoever is a lid. But let's not condemn PACTOR 3 because of some lids. I can tell you thousands of lid stories especially among contesters. This does not make contests and the rest of the contesters bad. They like contests, let them have them. We can all share our bands happily. 73 de Demetre SV1UY

ARQ FAE sends mainly 8 bits characters (8 bits to be able to manage all characters writings, as Greek). For bit transfert, you must use the TCP/IP link which is also available for FAE. This means that after the link done, you can transmit bits (put in form of characters) to Multipsk through the TCP/IP TX link. Through Multipsk and the TCP/IP RX link the other Ham will take the characters and transform back to bits. Note: ALE in general would need only 1000 Hz (to have orthogonal carriers) but 2000 Hz is better to fight against QRM QSB ... 73 Patrci Hi Patrick and group, Thanks a lot for the brief explanation. I hope your new ARQ mode will progress well and I would really love to see some comparisons vs other digital modes, especially vs Pactor 2 and 3, although I realise that it is early for this right now. BTW how can you operate your new ARQ FAE mode? Do you need USB and do you have to have your passband centered on 1500 HZ or something near there? Or will LSB do as well? I suppose it has to be USB and 1500 HZ just like other wide digital modes, or am I wrong? Keep up the good work OM. 73 de Demetre SV1UY

SCS says that Pactor III is 4 times faster than Pactor II and the code would indicate such. Thus the raw channel throughput IS faster and the BER should be better. But as far as performance goes at varying SNRs will make a difference in throughput. At a -5 dB SNR on the KC7WW channel simulator KN6KB measured the throughput of Pactor I/II/II as about the same. At a + 10 dB SNR, the maximum throughput of Pactor I was measured as ~ 100 NetBytes/minute. Pactor II measures as ~3000 NetBytes/minute and Pactor III measures as ~11,000 NetBytes/minutealmost 4 times that of Pactor II. 73, Walt/K5YFW Hi Walt, Thanks for reply. As I understand it if I need the speed it is a very good idea to upgrade to PACTOR III. I have PACTOR I and II at the moment and I am very happy with it. If the measurements are also true in real conditions too, then perhaps it is a good idea to upgrade to PACTOR III since when conditions are good the 4 times increase is great and one would hold an HF channel busy for shorter periods. 73 de Demetre SV1UY
