With nothing to do one afternoon I decided to make up a so-called
"interface" for my Kenwood TS-850. This would connect; my Heil
Pro Set, my footswitch and allow me to control the frequency of the
Without too much fuss (other than my usual problem viewing things

During the 2007 ARRL DX SSB contest I was using my Heil Pro Set.
While working 40m on Saturday night. Late in the evening I went to

clip leads and a VOM I determined that it was the wire between the 1/8
male connector and the mic element that had gone bad.
