Can you tell me whether the red is TX or RX?
Red is TX. PTT connects red to shield during TX and Black to shield for RX.
A closer look at the diagram on the mike's bottom cover reveals that it has *NO* receive-side switch contact. Only transmit.
It should work on any radio that receives without a mike attached.
And if unplugging the mike kills your receiver audio, this mike is not compatible with it.
The cartridge is a high-impedance type. Compatible with tube-type radios, and a very-few solid-state models.
But not all.
Thanks Guys! That helps a lot.
