When attempting a connection with another station I can make a successful connection but then the next transmission keys the transceiver but there is no modulation then seconds later it disconnects.
I Don't know if we are talking about the same thing here..but...I could connect with a station but would not move on from the 'handshake' and would disconnect....solution was for me ...turn off vox delay...have to say though I am not using Cat control
I found the problem. I had an intermittent USB cable.
We can not provide any value with a very shallow description. Screenshots, rig type, settings. the more the merrier.
