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.

|trantor12020||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.|

Why would a microphone have a magnet?
I don't think the mike in and of itself will have sufficient effect on the compass to be noticeable. The mike and wires should have no ferrous metal, however, if it has one of those metal discs on the back from which the mike hangs in a bracket, that might.
Regardless, simple enough to test before making a permanent install

Thanks to the views expressed here, I settled on an ICOM 402 with a command mike that wires to the helm. Looks to be a great radio and the command mike will give me access without leaving the helm to go below. I just have one more question....while there is clear direction about having the radio itself well away from the compass ( 3.5 ft +)...is the same true for the command mike.

|Freesail99||I suggested it's use in an energency situation. I also said that if you had the proper mmsi numbers you could call a friend. I never suggested that it be used freely.|
