[ICOM] IC-2100 audio

[w4upd]

Doesn't matter. There can be corrosion or dirt. I would back off the 
screws about 1/2 turn and re-tighten. Use the following URL to check on 
possible solution:

Also go to my FTP site:

and look at the files listed related to the 2100. Maybe they will help.

If microphone, I would try swapping cord ends and see if it persists.

>> Certain runs of the IC-2100 are known to have these problems even fresh from the factory. Usually it is the early models, but any of them can do it. I would check on line for the fixes. They usually entail opening up the unit and tightening the PC board mounting screws. Adding a ground strap to a couple of the screws and the case ground. I'd say about 90 - 95% of the time this remedies the problem. Otherwise the 2100 is not a bad rig especially for mobile and I like the old HM-98 mike with the tone button cover for mobile. Also, you might swap the RJ45 mike connectors around on the mike. Both ends of the cord are the same.
