The performance of this intercom continues to deteriorate.
It was unusable in the ICS position on my recent trip because of background static. Could only be used in the isolate position, which greatly diminished my daughter's enjoyment of the trip since we couldn't carry on a conversation. Even in the isolate position the amount of noise in my headset is increasing.
Is there an inexpensive way to determine whether the cause is external or internal to the intercom? DC gaussmeters are tremendously expensive.
The only external change I made was to move the co-pilot PTT switch from the stick to the instrument panel (so I could make the co-pilot stick removable). I didn't realize it was becoming so bad because I rarely have passengers.
