So I bought the cables I need for my Yaesu FTDX-1200 and have been trying for months to get this thing to work. I then put it off for a few months as life got pretty busy and I’m back at it trying to get it to work but no matter I do nothing is going to the radio. I’ve tried to get this to work on WSJT-X and CAT control just fails each time. I have the pads in the Digirig soldered for RS232 as this radio uses RS232 for CAT control. So finally I decided to do a loopback test and followed the instructions provided on the troubleshooting page here on the Digirig website. Now my issue is all I have connected to the digirig is the USB-C cable from Digirig to the Digirig itself and I’m getting character output in PuTTY without even connecting the TRRS to DB9 cable. Am I looking at a defective Digirig board? Or is there something that I’m missing here? Any feedback to help solve this issue would be awesome.
