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.
