WD40 leaves a residue. For electrical contacts, stop by your local automotive store and ask for a spray can of electrical contact cleaner.

Noise on Comm with Bendix King 97A Radio was created by George Polos
I have a Bendix King 97A Radio in my 415-C. Receiving transmissions nearby is usually clear but often (not always) distant transmissions from ATC and other aircraft is full of noise and hard to understand. Squelch control does not help.

I have removed the radio several times to clean the contacts (using WD40) and that seems to help initially but not for long.

I am wondering if I should try to replace the radio with another 97A (used) or if the problem could be coming from wiring or the antenna.

Any advice? Thanks.
