The electronic equipment room consisted of NAVAID monitoring and air-ground radio communications systems, composing of transmitter and receiver selector relay panels, regulated output amplifiers, dual channel audio amplifiers, power supplies, VHF and UHF transmitters and receivers, and voice frequency signaling equipment.  Most, if not all, of the equipment were a carry over from CAA days and were still in service well into the 1970's and even 1980's.
