[amsat-bb] WISP replacement?

[Edson W. R. Pereira]

The Linux version of PB and PG talks to a pseudo TNC using the native Linux
AX.25 sockets. It has been more than two decades since I have last used the
native AX.25 sockets and, as far as I can remember, it was not trivial. I
suggest modifying the PB and PB software to speak the AX.25 KISS over TCP
protocol and talk with DireWolf, a software TNC that implements the G3RUH
GFSK 9600 bps modem. DireWolf can be found here:

https://github.com/wb2osz/direwolf

I will try modifying PB and PG to use the KISS protocol as soon as I can
spare some time.

DireWolf could be used with a classic transceiver via soundcard and also to
a SDR receiver such as GQRX or GNURadio and a classic (or SDR) transmitter.
The software modem could also be implemented directly in GNUradio as well.

It will be a blast to operate a PACSAT BBS again.
