Re: [digitalradio] The Basics On WINMOR
The beta and software being developed in the foreseeable future will be focused on Winlink 2000. It won't have a peer to peer function, unless it is temporarily put there as we had with the SCAMP protocol some years ago. Even then, they planned to remove PtoP once the software was made available for general use. Eventually the protocol will be tested and deployed and as Rick has pointed out: "Remember that WINMOR was not designed to be just another sound card mode like PSK31 or Domino. It is designed for binary message forwarding and is part of an entire email system (WL2K) and for it to work and be properly evaluated all the parts that integrate the new mode must also be built and tested." Also, he says he will "probably make a DLL of WINMOR available for others to use." Of course all software developed by the Winlink team has been Windows centric and will continue to be. There has been work done by a Linux developer who has been able to provide Telpac and now RMSpacket clients for Winlink 2000 and perhaps he will be able to make an open source Linux version of WINMOR. The final design won't be ready until real world beta testing is done. The thing that struck me the most is that he sees Pactor becoming obsolete since it is not that good of a mode compared with WINMOR. Of course Pactor 2 and Pactor 3 are much more competitive with any sound card mode for the forseeable future. So the beta testing will be operating the Winlink 2000 system as you normally would, but using a sound card mode in place of P2 or P3. Ideally, everything else will be about the same. It should be similar to how SCAMP was beta tested, except when conditions go near to zero dB and maybe even a bit below zero dB SNR, the mode will continue working. SCAMP failed much below +8 or +10 dB SNR. The 4 FSK mode intrigues me the most as having a robust mode that can handle at least moderate ISI and Doppler along with the 15 or so dB capabilities for weaker signals. As a comparison, the RFSM sound card modems, although they are based on MIL-STD-188-110A, did not implement the more robust modes, particularly the 75 bps mode designed for the worst conditions. It would have been fascinating to see how well (or not) that mode works. A friend of mine who uses this stuff regularly for military applications says that these "ALE" type systems are not that great. But he also does not have any experience with ham HF modes. If anyone else does have the experience with both it would be appreciated if they would share what they have found, especially in terms of robustness and throughput. 73, Rick, KV9U Andrew O'Brien wrote: > I am a member of the WINMOR reflector and I am encouraged by the > author's intentions.

RE: [digitalradio] Using CTSS on a digipeater?
I'm with Vince on a number of points. If there's really a serious emergency, that will benefit from packet radio, chances are that the hobbiest hams are not going to be on the air, unless it's in support of your goals. I think it's far better to have the local community exercising your digipeater for you, so you know if it fails. If you're truly insistent on having the ability to lock out stations, it'd be better to do a couple of things to achieve that: 1) Use a TNC that allows performing over-the-air settings modifications 2) When an event happens, and you determine that the level of emcomm traffic vs. regular user traffic requires it, set up a beacon that frequently (every minute or two) informs all users that the digipeater has been configured for emcomm operations, and create a buddy list of stations that are allowed to connect and digipeat via the digipeater, and implement it. Another alternative that can be done remotely is to change the "MYDIGI" setting to respond to something else, but that's only a short-term fix, since anyone that's monitoring can see the digipeater callsign. Perhaps the most important thing, is if the operation is of a limited period, remember to set operations back to normal operations before shutting operations down, or when the emcomm traffic volume is reduced enough to support normal operations. >From a technical perspective, using CTCSS as an operational modifier is a poor solution, for the reason Vince mentioned, and additionally, depending on the TNC and radio combination, having the the CTCSS tone present at the input to the TNC may cause it to make more reception errors than if it's not present. Also, anything that delays the digipeater (especially) from being able to tell that the channel is busy, and that to wait for the channel to clear before transmitting, is going to kill performance and require many more retries than leaving the digipeater open.

Re: [digitalradio] SCS PTC with P3 Uses ?
To quote from a response given by Rick Muething on a different group: "WINMOR sound card mode. Probably shareware model. Will require a decent sound card and isolated sound card interface ... WINMOR should give better performance than P1 but probably not as good as P2/P3. This is very complex software so I would not bet on it being stable for at least 6 months." Not sure how much to read into use of term 'shareware' versus freeware or open source. Also, considering developers are major forces in Winlink, I would not be surprised if WINMOR is rolled out initially as a Winlink HF comms package developed using Windows Net software.

RE: [digitalradio] on another note
"I don't think it would be technically very difficult to do something equivalent to P3 with sound cards. I think that it would even possible to do much better with, for example, multi-users protocol." RFSM8000 has come as close as anything so far, but it's weakness was operating well under poor conditions (read normally poor these days) "The problem is the time necessary to do this. An amateur can work (with pleasure and passion of course), let's say a day per week, when a company can make work a small team 5 days a week. Now an amateur project must be short in time (several months at a maximum) as it is done for fun. Working on the same project during years seems very difficult (and surely boring) for amateurs." No kidding.. it is amazing and very appreciated with what you and other software authors have done, and is especially important when it is done as a hobby. "Another point is that the number of Hams really interested in ARQ modes is very weak..." I can't answer that , outside of the fact there are a pile of winlink users. Think you might underestimate the number of folks interested in ARQ soundcard modes, and maybe this is an opportunity for Andy to do a survey on his website? "Note: have tests on the minimum S/N versus the data rate done, for pactot P2 and P3? (as it is difficult to trust commercial data) " don't know, but think so . but my ear tells me it works better than OLIVIA, which is about the top of the heap right now. I cannot hear the other station and yet the connect runs at fast speed. John VE5MU

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 gleefully participated in some of the lively debates on these posts and have come awfully close to being punted by moderator Andy. So you are asking yourself by now, where is this crazy Cannuck going with all this?? Simply put, ladies and gentlemen, I have seen the light ( actually a whole mess of little ones but who is counting) Over the past couple of weeks I have been testing a SCS PTC2 usb modem with a pactor3 license, and have come away amazed and humbled by what this thing can do. It is faster than ANYTHING else I have tried, including RFSM8000, and works further into the weeds than anything else I have tried. I have connected to a RMS station midday close to 1000 miles away on what I would call a "dead" band. I have connected to RMS stations at least 500 miles from me on 80M well into mid morning, and resumed these connections by about 3PM , still when nothing else could be heard on the band. I had in the past heard the claims that this modem would work 10db into the noise. At the time my reactions was "yah,right!!!" but it really does. If you have a chance, try it out . So my thinking has undergone an abrupt change of direction, from using soundcard modes with internet access, to using P3 for primary links and sound card modes for the last mile or so.. and would like to hear other opinions. we all know the givens about pactor: the modems are expensive, the operators insensitive, proprietary hardware and software etc etc. but how could this mode be incorporated with current soundcard software?

I have to agree with John. During the flooding along the Mississippi river last spring 2M was just about useless. Since I had a HF set up in my pickup with a VX1700 mounted all I had to do was set up the laptop and SCS modem.
