Receive works just fine. If I select the PTT button from soundmodemconfig, it makes a lot of 'noise' but this sounds to me to be quite a bit higher frequency that the 'hiss' sound of normal 1200baud AFSK. If I use the beacon command, or some other AX.25 commandline tool to 'send' a packet, the speaker just makes a clicking sound. If I stop soundmodem, and use the linux play command to play a simple music wave file, all sounds well. Any ideas? I'm in the process of building a soundmodem system on a desktop PC (as opposed to the laptop). I just want to check whether I get different results on a full PC than I do on the laptop. My /etc/ax25/soundmodem.conf is included below. thanks - jim
