I recently got an Alinco DX-SR8 (HF only transciever [USB, LSB, CWU, CWL, AM, FM] with an 8-pin mic), and I was wondering how I'd be abl to send digital (PSK, RTTY, Packet) with it, as it doesn't have a radio to computer cable. Is there any possible way to feed signals from my sound card into the 8-pin mic jack? If so, how would I build a cable for this? Which program should I use? Thanks!
