I recently received a Digirig and cables for my Yaesu FT-8100.
- USB-C from Digirig to USB-C on laptop
- Audio cable out of Digirig to DATA port on back of Yaesu FT-8100
- Winlink Express set to Peer-2-peer and attempt to Direct Connect to fellow operator.
Three tries, and failure to connect is reported. I never saw the PTT light come on, nor hear on another radio monitoring the same frequency anything broadcast.
When the fellow operator tries to connect to me, I hear and see data (as I should) on the VARA FM window with the correct call signs, yet again - no PTT action and connection fails.
Is it the Digirig or is it the cable? How do I trouble shoot this?
This is a frustrating start. Since you are monitoring locally, you have a great tool for troubleshooting.
Denis K0TX has a troubleshooting guide:
Troubleshooting Digital Modes – digirig
which presents methods to check audio out of the Digirig and check PTT being pulled on the connector to your radio.
I google’d a bunch of videos to watch. The one that shows how to test the cable for PTT activation was helpful, as mine proved to be functional. Also, I noted that the cable to the DATA port on my radio was not quite seated. I checked for bent pins, all was well, but this time when I plugged it back in it sort-a clicked, so I felt better about that.
I also made sure the Windows driver was correct and updated - then WAH-LA! everything began working!
Chalk this one up to loose cables and an old driver. Problem is resolved!
Congratulations and thanks for following up with the details of your troubleshooting!
