Don and I have extensively discussed the use of the microphone 5 volt
line. I fully agree with his strong suggestion to not use it. In my
case I found problems with RF Feedback that I have been able to
directly associate with my use of the power pin, even though I heavily
bypassed it in my interface box.
I solved this problem.
Instead of +5, I wired a jumper block to a piece of wire, ran it to the
+8 regulator on the RF board, ran the wire up beside the connector and
pushed the jumper wire on the microphone half of the connection. I
already had several accessories wired for a Kenwood TS-430S, which uses
+8 volts as well. Now the accessories work equally well on either
radio.
