trantor12020 is on a distinguished road
a mic is like a speaker working in reverse. the magnet there is weak, would probably not affect the compass at the helm. the command should have both a speaker and mic built-in, or maybe the speaker/mic is same unit (dual role) since its a simplex system.

k1vsk will become famous soon enough
Didn't think of the speaker in the command mike Cam - you're right.

"a mic is like a speaker working in reverse" is true but only for the very old style carbon microphones and not for the contemporary electic type commonly used on boats.
