[AMRadio] TCS-12 Receiver Pinout

[Joe Bento]

Thank you, Dennis!

That is a major help!  I might assume that since I do not have the companion 
transmitter, I can tie B+ to pin 3 of the connector as well? (And recall this switching 
in case I want to mate the receiver to a transmitter of whatever flavor at another 
time).

One more question regarding the radio is the mating female connector to build a 
cable.  Looking through the DigiKey catalog, it looks like Amphenol, AMP, and 
Cannon all make potential mates for the TCS receiver.  I always get a bit confused 
trying to sort through the connector info in the catalog though.  Does somebody 
know what series (current manufacture) of the connector I need?

Thanks again!
