Jim and Ed: Jim's information is spot on, and no matter what the situation,
there is a lot of useful information. However, one of the things Ed needs
the transformers for is to soften the DC switching pops that occur when he
switches microphones between radios. While there may be better and more
elegant methods to solve this, the transformers work. .--73, Mike WV2ZOW
