Not all the channels were usable in one area. Tuners were not very good at rejecting harmonics back then. Today, we have phones with four or five radio receivers and three transmitters operating without interference. It's amazing that works. Receivers are far, far better than they were in the tube era.

Surprisingly, a lot of that improvement comes from miniaturization and from better capacitors. The tubes themselves weren't really bad but they were power hungry and physically large. The capacitors, however, in the 1960s were terrible.

Doesn't a more sensitive receiver make the harmonic issue worse? In one case it fades out into background in the other you precisely measure it!

tl;dr as more spectrum was used in the late 1940s a channel had to be freed up to deal with interference issues so they picked channel 1 and simply choose not to renumber. You'd think the article would explore why they didn't renumber, but nope. Legacy hardware and possible consumer confusion seem like the most likely speculation.

you tl;dr people are doing the lord's work. thank you
