Rear Intercom Squeal

[traders]

My wife and I ride a'00 gl1500. Recently I purchased a new nolan helmet for my wife with the goldwing headset built in. While all previous helmets and headsets worked fine, this one squeals like a banshee most of the time. She refuses to use it because of this. I've returned it for repair but it was returned with the comment that nothing is wrong with it. Very frustrating.

Has anyone else had this problem and know of a decent fix?

I have had that happen with my rider headset. The connectors were dirty inside the female plug and cleaning with contact cleaner spray and lubricating ended the problem.

Often a shorted (or almost shorted) mic connection can cause a squeal in mic preamps, you might want to check for dirt or a problem in the connector.

Is the headset specifically for Goldwings? If it does not use a dynamic microphone, and instead has an electret mic, that could definitely cause the squeal.
