I am working on a TS2000. I set it up for WL2K and had it working yesterday. I wired the ACC2 cable to work on the SUB input/output. I am using a KPC-3+ TNC.
Now when I send a message to it from Winpak it keeps transmitting on the Main side. It receives on Sub and transmitts on Main. I pressed the split key and it did not help. I did a full reset and it did not help.
It was working yesterday. Receive and Transmit on Sub and sending the signals through the ACC2 port. The TNC was happy.
If I use the mic, it transmitts and receives on the Sub side.
