Rick , Just on a side note, yep I have dabbled on HF packet, just connecting to european nodes etc. Never had much success, I'd have thought NVIS on 80m be quite good. Anyway there are some promising HF sound card ARQ modes coming out at the moment, Like psk mail and flarq for FL digi (even windoze version). Surly some of these ARQ modes could be implemented into a local BBS system somehow. Just thinking out loud. Regards Merry Xmas everyone from Dark Winter Scotland.

With the advance of technology, I moved away from packet around 15 years ago! It is just not robust enough for HF and can only go a Short distance on VHF, compared with newer modes What seems like an unfulfilled need is a framework similar to packet, With the ability to insert different modes as they are developed. You Would not have to keep inventing the wheel over and over. This would mostly have practical value for groups that want to set up a BBS system. For example, I have monitored the packets on an 80 meter BBS Here in my state where most of the transmissions are retries. And this Is during the day under NVIS conditions. A much more robust mode needs To be used. Then you would be able to send and receive direct or time Shifted messages. This is the one thing we can not do with any other System, but there does not seem to be any interest in developing such a System. At this time, it is true that a slower baud rate packet system could be Used, such as the software 110 baud speed available in Multipsk. This is Why hardware packet TNC's are a poor choice for our advancing technology And why almost no one uses them anymore. You are locked into a mode Developed over 30 years ago with no FEC or ability to be adaptive for Conditions. And yet, I admit that if you want a BBS system today, what Other choices do you have? 73, Rick, KV9U Bev & Jerry Chambers wrote: > I have used MixW for packet, both on 2 meters and on HF and found it > to work fine. > > Jerry - W6LQR > > > __________________________________________________________ > Plan ahead with a quick and convenient rental car.
