[ARC5] SCR-522: Rethinking The Old Gal

[D C _Mac_ Macdonald]

I never had the 522 receiver, but still have the 522 transmitter I fitted to a 19" rack panel.  I also converted an ARC-1 to VFO but never finished it and it went to landfill after the 3 May 1999 tornado here in OKC.

In the memoir "MIG-15 To Freedom", 1996, No Kum-sok says the KW MIG he flew had a HF radio, unlike U.S. fighter aircraft. He clearly thought the NK aircraft communications inferior.

There was a later book, 2015, and it's stated to have more information from released intelligence. I have not read the later book.

This pilot settled in the U.S., took the name Kenneth Rowe, had a career as engineer in the aviation industry, and is retired in Florida.

>Some years ago someone was selling the original VHF radio out of a Mig-15 on ebay.  It was recognizably a Soviet version of the SCR-522.  So Korea probably was the first war where both sides were talking on basically the same radio.  Most USAF aircraft in Korea used the ARC-3 but there were still plenty of SCR-522 in use there.



The ARC-3 was based on the SCR-522, but had the advantage from the US viewpoint of using what we would later call "Line Replaceable Units" so you could easily yank just the receiver or transmitter and swap it out rather than pulling the whole big box.  And you could distribute the weight around the aircraft more easily.



As for a genuine WWII set, while ARC Type 12 are a lot easier to get running, the VHF ARC-5 crystal controlled receiver can just use the set's built in VFO and ignore the crystals.  You don't have rip all the crystal sockets and relays out despite the fact the conversion articles told you to just that - as was done with the example I have.



In any case, Dave is to congratulated.  I don't know of anyone ever using the SCR-522 for amateur use "as is."
