The reciever I had was a Hitec 4 channel HS148. Yes when someone turned on the frequency next to mine (I was 68 he was on 67) I did experience very minor glitching but it disappeared. The moisture could have been there before or after the Bonanaza crash let me explain.

When the Bonanaza crashed it survived very well. It had a hollow plastic structure and thus the radio gear was fine When I did get to the plane, the rear receiver casing had popped off. Now it was hot summers day and had it had been hot for quite a while. I checked out everything at home and replaced the casing (I had replaced it at the field before but had inspected at home). Now I very breifly looked at it so the rust could has been missed. So I cant be 100 percent sure about wether it was damaged before or after. I had new crystals after the Bonanza crash. Although if the receiver was damaged before it would ecplain the Bonanza crash. Both Travel Air and Bonanza went into left had spirals by the way. I know somebody who uses Webra recievers and has no probs.
