Hey Tony!

Don't have an answer for you but I'm really glad to see your message.  I 
have been experimenting offline with TX through the UZ7HO high-speed 
soundmodem using recorded FalconSat-3 9k6 data for my RX stream.  However, I 
hit a roadblock with the DCD... I could only transmit when there was no 
incoming data detected, which is very rare!

As for your live, on-air testing, have you tried any APRS messaging 
transmissions instead of attempting to access the BBS?

I tried accessing Falconsat-3's BBS via PFS3-12 this afternoon, but I
wasn't able to connect. I'm using Easyterm with an experimental
full-duplex sound card modem by UZ7HO. This version has it's DCD
disabled to allow full-duplex operation.

Assuming the BBS is turned on, are there any special parameters needed
when using a simple terminal program? It would be nice to use Wisp
again, but I don't see a way to use a sound card modem with this program.
