Nope, nope, nope ...
Exciter: frequency 1 select wire from the Channel Element on the
circuit board goes to P-902, pin 15.
Receiver: frequency 1 select wire from the Channel Element on the
circuit board goes to P-904, pin 2.
Those specific pin numbers must be grounded for the receiver or
exciter to operate properly. The usual policy was to ground the
frequency 1 select on the center board (Control Board) at the
factory on all one frequency radios prior to shipment.
