I thought I would separate this video from the others. It was a look into CB radio in the UK circa 1981. I'm not any kind of expert on CB across the pond but I seem to recall they didn't officially get legal CB frequencies until much later.
The current channels mimic the US by having 40, but that's where the similarity ends. In the UK the 40 channels are up in the high 27 MHz range [27.60125 MHz - 27.99125 MHz], just below the 10 meter Ham band using FM mode.
