Don't blame me. It was a crappy RCA NATO radio design that required every member nation to sign off on design changes. Even as a tech, I could have made a lot of improvements starting with a better transistor in the front end. Motorola was the only source, and it had been obsolete for several years when Cincinnati Electronics took over the contract from another company. Motorola agreed to make a batch, but wouldn't guarantee that they met Mil Spec. They shipped over 11,000 transistors to be tested in house in an attempt to get 10,000 that qualified.
There were about a dozen manufacturers, including someone in Pakistan. It was early '60s germanium technology, at best. Crystal mixers to synthesize the Local Oscillators, and designed to replace the PRC-25, which replaced the PRC-10. It used the same battery, ignoring the 90 V B+ and operating the radio off what had been the filament supply. It used the same crappy Korean War carbon microphone handset and antennas. In other words, it was a low budget radio designed to replace crap that replaced crap. The only thing that it had going for it was module interchangability, implying that it could be serviced in the field by swapping modules. It was to be replaced by the PRC-70, that used modern ICs and digital synthesis to generate the Local Oscillators. They were intended for short range communications only. There were a few linear amplifiers built for them to put out something like 20 watts instead of a half watt. I saw a few at Cincinnati Electronics, along with the motorized antennas designed for tactically equipped Jeeps.
BTW, that was the same place where a security guard accused me of stealing a 'GRC-106, Complete' and carrying it out of the plant in my shirt pocket. That was about 600 pounds of electronics, cables and spare parts. The head of security got mad when I laughed in his face. then I asked who made the complaint. He refused to tell me, so I asked how many were missing, and what were the serial numbers. Finally I explained that two, 'GRC-106, Complete' filled one pallet, and required a forklift to move. He wasn't amused, but called that department for conformation. He finally apologized.
