Thank you again VW'er,

Unfortunately, all talks of electronics fly right over my head.

Off on a slight tangent, I purchased two old military headsets that
have helicopter type plugs many years back. What do I need to get
these working (being compatible with civil radios)? Something about
the mic not being compatible was what I remembered, but I really need a
layman's term to understand. I fly choppers, so the one plug thingy
fits fine, no need to change to airplane's two plug type, just the mics
I think something with impedence?
