An easy test for you. If you take an ohmeter from the shield of the
mike cable at the base of the mike or where ever you can access it,
and then touch the other probe to the chassis of the radio, do you get
zero ohms? If your ohm meter has a "Lo Ohms" scale use that one.
IF the continuity is there, that should eliminate the "pin 1 question".
NOT TRUE -- depending on the sensitivity of the Low Ohms scale on your
VOM, it is VERY unlikely that your VOM can tell the difference between a
connection direct to the chassis and a connection via the circuit board
to the chassis. My Fluke, carefully calibrated and with compensation for
the test leads can, but most VOMs cannot.
