In Spain in 'ancient' times it used to be UHF/VHF channels. Two of them. First, THe only channel, a la BBC, but from a dictatorship, TVE, Television Española, and later, TVE2, in a different band (I think it requiered a separate antenna and/or tuner) which was depicted as more culture bound (the regime opened up a little in the early 70's) and with less hour per day that the main channels.

The new channel appeared when my parents were kids, around the late 60's.

But, for incredible stuff happening in the 90's, I remember watching the MTV illegally in very early 00's due to a semi-pirate really local TV channel. They used to broadcast chiptune videos at late night too, it was really weird. Even some early Flash videos and animations too.

Good times to own a TV tuner in your PC among the teletext when you had to go to a cybercafé to basically work offline and batch-send/downloaded everything within an hour while you chatted with your friends and some potential GF. If you knew how to pirate the Nagravision cypher from paid TV channels (something lame to decode with an Athlon in real time) you often could watch (and dump) movies with, well, VHS quality (MPEG2 was just a thing for cable TV and DVDs) but at least after the long rip (13h per hour, and then the encoding to XVID/DIVx) you could watch a good movie months after being displayed in the theaters.

Here in the UK, TV was broadcast on UHF and VHF up until the mid-80s. Where I grew up in the north-west of Scotland it was pretty much only ever UHF - salt spray and 140mph winds tended to take out the long dangly "Band I" VHF aerials for 50MHz-ish.

But over here in the drier and less windy north-east, there are still combination Band I/III aerials on a lot of houses. They must be at least 40 years old now, and mostly still hold up. The UHF aerials you buy today last a couple of years before the plastic bits go brittle and they fall apart.

Oh, and I know where there are at least three places that still have BSB Squarial.

Just as a slight extension to this, in the UK VHF was used for the original 405 line (~376i) analogue TV system used for 1936-39 and then 1946 until it turned off in the 1980s, so any ariels still up probably haven't been used for decades.

UHF was used for the newer 625 line (576i) PAL colour TV system, starting in 1964 with the launch of BBC2 (colour in 1967) and then BBC1 and ITV in 1969 when they went into colour. Analogue TV was switched off in 2012, and digital TV is only UHF only.

BSB (British Satellite Broadcasting) was a failed satellite TV service notably using a smaller square dish compared to their rival Sky (old Sky analogue dishes were quite bigger than the "minidish" used for digital, and you don't see them around much either). They also used the fairly obscure DMAC TV system, whilst Sky used standard PAL. The pretty quickly "merged" with Sky, hence Sky's legal name for a long time was British Sky Broadcasting (BSkyB).

There are actually existing copies of 405-line TV programmes on tape, because domestic VCRs would quite happily record it. Each "stripe" of a head rotation is a complete field, and as long as they're coming every 1/50th of a second it doesn't really care what if any line sync pulses you want to feed it.

I don't remember us having 405-line TV because by the time they built out transmitters that far north in the early 70s there was no point, but I remember going round to a neighbour's house down south with my dad in the late 70s when they asked him to repair their TV. I remember the objectionably loud 10kHz line whistle which my elderly neighbours just couldn't hear :-)

It was fun when the weather was good (some high clouds, no rain, no fog, preferably warmer weather) to receive the BBC across the north sea on the higher channels, quite fun to watch when there was nothing in the Dutch channels (we had no cable connection, physically none). The french1 was only possible with reflections so very noisy. Canal+ was also sometimes interesting but that was scrambled.

Dutch VHF was patchy due some kind of interference I recall, but the channels were mirrored in UHF.

That web site is focused on analogue-era UHF-band TV in the U.S.A. with rare mentions of the many Canadian UHF-band channels that were receivable along the northern border back then.

I immediately looked for any channel 37 assignments and found just one, which was assigned but never used. 37 was intentionally kept clear by international convention as a safe band for radio astronomy.

When were you watching? The US All Channel Receiver Act was passed in 1962. Prior to that UHF stations did struggle in the first decade of UHF TV in the US as few TVs had UHF tuners. The situation improved after that as they became standard and more and more people could actually watch the extra channels.

Late '70s through the '80s, which is consistent with your citation here.
