[VHFcontesting] The digital modes and the Sept contest

[Mark Spencer]

I don't believe I have ever used WSJT-x with my FT736.   I have however used the same interface hardware with WSJT-x and another radio and I don't recall any issues.

In this scheme, WSJT-x just sees a serial port that it uses for PTT along with sending and receiving audio via sound card built into a laptop.  

Most of the time for WSJT-x I just use the USB interface on another radio for MF, HF and 50 MHz.   

All the best
