So if we heard those relays switching then we're dangerously close to damage occurring? We found that we'd be listening and usually right in the middle of a guy giving his call you'd hear a click and a short bit of muting in the RX... Looks like swapping out for the AUX RF input isn't going to help me in that department. Perhaps I'll get greater isolation between the two receivers in that configuration though.
