Hello
I am part way through my RV7 build and have just about finished installing my Garmin suite, including a GTR200 Comm.
The issue I am having is that from the moment the GTR200 is powered on, it is stuck in RX mode. I have tried a variety of things including:
- Removing either end of the antenna cable (either at the antenna or radio) and this instantly causes RX to turn off
- Pushing the volume button for manual squelch which doesn't help, but I am unsure how to actually increase the squelch after doing this
- Tested continuity on my antenna cable (RG400) and confirmed that I have a good connection between the centre pin to centre pin, and then shield to shield
- My RAMI AV-17 whip antenna is mounted on the belly and I am reasonably sure has a decent termination to the airframe via the 4 mounting bolts for a ground plane
Running out of ideas to work out what my issue is. Any suggestions would be appreciated.
Thanks,
Jonathan
