Yes I had read about the change in frequencies and the “lost” channel 1 to accommodate the 40 odd MHz IF whereas Europe went for 30 odd MHz and kept the Ch 1 freq.

UK UHF valve (tube) tuners were not very sensitive circa 1964/65 when UHF TV started in the UK, quickly changed to transistor which were much better.

USA started with UHF in the early to middle 50’s, how good was the UHF performance of those early tuners?
