I have an Anytone 878, a baofeng Uv 5R and they work fine with sending email on winlink.
I connect up the 50x2 using the same cable via the rj45 adapter and get and get the reply but no connection. I read somewhere the radio is not switching over quick enough?
Can you share your audio level settings for digirig and volume knob on the radio? I can not get the VU level for vara fm correct. i can connect to station but it will not acknowledge. but my crappy little HT connects no problem. very finicky radio this 50x2
