Well..................................................... I tried the KPSK but as far as I can see it has some problems that go a ways back with no support showing from the developers. SO, I decided to blow it off. Did find a TWPSK for Linux and installed it. I have to run it from CLI, but I can live with that if I have to. When I try to start it I get this: ***************************************************************** Compiled with @(#)Motif Version 2.2.3 Running with @(#)Motif Version 2.2.3 Using full duplex mode! Cannot open PTT device /dev/ttyS1: Permission denied Can't open code table file 'psk31.cod' **************************************************************** I'm thinking the error message is because there is no radio hooked up to the computer. I do have my backup computer dual booted with Win98 [ the last version you could make a functional start up disk from ] so I downloaded and installed digipan. I think someone mentioned they had a schematic for a simple interface unit. Would it be possible for them to send it to me. If I can get things working, what the heck give it a shot. -- (o:]>HUGGLES*<[:o)<br> Billie Walsh<br> The three best words in the English Language:<br> "I LOVE YOU"<br> Pass them on!
