I have purchased a cable for this radio - and would like to verify my setup. I have it plugged into the Digirig mobile - and a usb cable to my computer. Does that sound correct?
I seem to be having a problem getting the transceiver to key up on transmit - have I missed something obvious?
Probably not, but we need more information. Are you testing the PTT by shorting pins on the TRRS connector, or using software on the computer? Do you have a software TNC/modem like soundmodem or Vara FM installed? That software has settings for the COM port which corresponds to the Digirig.
