sure it doesn't have two of those reed contacts?
That looks exactly like the piece I pried out of the chassis and there was only one magnetic reed contact soldered to the center pin of the SO-239. I have another Syntor I'll be tearing down so I can double check.>>> If it helps anyone, this is the model I'm working with <<<
Still can't imagine why the radio would want to open circuit the center conductor to the antenna jack. Kinda' hard to be a radio with no RX or TX.....
Of course, that never stopped Heath
but this is a Motorola.
