[amsat-bb] Re: Help please from folks with soundcard "TNCs"

[Joe Veldhuis]

All of my home computers run Linux. On that platform I use soundmodem as the packet modem, the AX.25 utilities suite for BBS connections and whatnot, Xastir for APRS data plotting, and a mess of little apps I wrote myself UI messaging via the birds.

My laptop dual-boots win2000, and on that I use AGW Packet Engine as the packet modem, WinPack for connected stuff, and Xastir and the aforementioned homebrew apps (running under Cygwin) for UI/APRS.

I use Predict for satellite tracking on both.

By the way, for anyone who might have experience in the matter, I have had trouble getting soundmodem to decode anything other than 1200 baud AFSK. 300 baud seems to work via FM but not SSB; 9600 baud FSK and 1200 baud PSK don't work at all. Oddly enough, however, they all (seem to) transmit perfectly. Has anyone run into a problem like this? Is there a solution?
