[MRCA] PRC-47 Video

[Ray Fantini]

I just put up a video on the AN/PRC-47 that includes the Synthesizer offset and VOX modifications, don't know why but most PRC-47 radios were modified by Collins for just VOX operation only. Makes it good maybe for fast CW but leaves a lot to be desired on voice or super slow CW. No idea why they did a PTT line that allows normal PTT operation on the radio but never connect it to J2 pin 11, maybe it was left up to unit configuration? Who knows. Have seen no documentation to support why they did it that way other than being Collins. The Synthesizer offset is biased on the "K4CHE" design with a couple small changes.
