I just picked up a new TS-480SAT yesterday, and had the Signalink USB from my previous radio. I made up the cable for the Signalink to connect up to the Data port on the 480. I tuned it up in Digipan, and it works perfectly in there, audio out and drives the transmitter. I switched over to Ham Radio Deluxe(V.5)/DM780 and it keys, but I get no audio out to the radio. I tried messing with the PTT options in the program options and neither seem to have any effect on it. I checked the soundcard settings as well, and they are correct. What else could be the problem?
