It struck me as a little ironic that radio designers had put a lot of maths, headscratching and mechanical design into getting away from the embryonic 1920s superhets with an array of individual variable capacitors and with arbitrary scaling to the sophisticated, civilised ganged-and-tracked superhet with a single tuning knob and tuning dial that anyone could go to and easily find a station with. Then the RA17 came along.... and both hands needed to dart around again. I wonder what US oppoes who were accustomed to the contemporaneous R390 with its complex but thorough ganging arrangements thought of it.
