[ICOM] IC-2100 audio

[w4upd]

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.
