Does anyone out there happen to know the pinout of the power connector
on a Motorola TK-690H transceiver? Also, does it a require that a mic
be connected to receive? I picked one up at a surplus auction in
unknown condition with no power cable, and I'm trying to find out if it
works before I go and spend money on a cable & mic.

Thanks!

You should ask a dealer. It is a recent model. Mic is not required to
receive. The squelch is set in menu. It is a 45 or 110 watt 30-50Mhz
model.

My recollection is that you could open the PA section and power it with
clipleads but that is 5 years old in my memory.

The unit can be wired for an external speaker though, with the internal
speaker disabled (because there is enough audio power in the radio to blow
the internal speaker). You would need a Detailed Service Manual to do the
mods. There are also options to remote the head and do various other wiring
options like ignition sense.
