All that you say is most likely true but would have Britton survived long enough to develop a better VHF transceiver in the 1940s?See: https://www.psychologytoday.com/us/blog/am-i-right/201411/the-cult-of-the-imperfectThe B-17G was equipped with the SCR-522, don't know if VHF was even on the B-24. You are correct, the ARC-3 served a long time. The MPN-13 RAPCON (radar approach control) had three ARC-3s and three ARC-27s. They are the only avionics sets I ever saw as a Ground Radio Tech in the Philippines, circa 1969.

That radio may have provided happiness or pleasure for you but I will stand by my original comments, poor or no high level injection on the first mixer, tuning too touchy and a mechanical monster! That is why radios like the ARC-1 and 4 served decades beyond WW2 with later designs like the ARC-3 serving well into the seventies but the SCR-522 was dumped in mass at the end of WW2
Think if your doing a WW2 ETO B-17 the SCR-522 has to be included, but a B-24 used in the North African theater or a B-29 in the Pacific theater would have the newer sets and not that first generation radio.
But, that’s what I think.

In my opinion, the SCR-522 design was highly utilitaristic to fit its mission.
It was simple to put together, easy to maintain, fairly reliable, cost effective and easy to use. I believe that the SCR-522 perfectly fit its initial application (single pilot fighter).
Its good performance made the SCR-522 a stable cornerstone for aero VHF communication. From an ham point of view, its crystal control and rudimentary tuning made it a unusual set to work with. I played with them in the early 70s, and in a moment of nostalgia, I did acquire a brand new 522 a few years ago.

Well, IMHO, it is a typically British design: not particularly ergonomically arranged and too spread out.
It is just plain ugly.
However, as you say, it was very important.
The ARC-3 and its later developments were better rigs, but, again, IMHO, the 522 started the process.
