Finalizing my wiring/avionics set-up and trying to figure out where radio static noise comes from. I have GTN 650 and SV-Com 425
Noticed when I unplug GTN650 from antenna @ antenna noise disappears, when plug it back in noise comes back. I checked cable to make sure it is not shorting between pin and housing, it is all good. However, when cable plugged in to GTN it becomes shorted on the antenna end as if GTN has a short on the inside? Is it normal? Anybody knows?
