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.

Similary, I have used Multipsk's packet modes on both HF and VHF with 
Success. 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?
