Thanks, Bonnie. While I'm sure that would solve the problem with the hand-held, it only addresses half the issue. When the XYL is in the shack (her computer desk is 90 degrees and 4 feet away from mine) I use the headset mic so as to cause as little QRM to her while she works (she works from home). I guess unless someone tells me that a rotary wafer switch won't do the trick for me, I'm going to try to build one.
