Other than FLDIGI, which swamps the RPi processor, does anybody have or know of a *WORKING* PSK-31 program? I have tried twpsk, gpsk31, phaseshift, linpsk, gmpsk, and of course FLDIGI. Other than FLDIGI, they don't load, abort with all sorts of errors, etc., etc.
FLDIGI does recognize my SignaLink USB interface that I have connected to my Yaesu FT-817ND.
I to am interested, after a few years recovering from illness, the RPi has pulled me up by the bootstraps! and I would like to use all or at least psk in the "sound card modes" but being very new to linux I cant seem to setup the progam with the correct sound card info, the default on the program refers to "/dev/dsp, dsp 0 1..2..none of which work
I can see the other devices, also see the external sound device but dont seem to having much luck.
Using fldigi, I have been able to send a transmission that was copied on 40 meters. The send part works. What doesn't work is the receive portion of the program. I use the Signalink USB sound card. I can see the waterfall. All I get is gibberish on the screen.
I certainly would love to help work on solving this problem if somebody would point me in the right direction.
