as easy to tune as VHF. Thats why detents got added to UHF tuners or
the set had varactor tuners with presets.

The guy I bought my VHF-only Portacolor from said they won it in 1966, so that seems to line up with your mid 60's timeline for Canada.
It turns out the lack of UHF is kind of a pain for me, since I have a handful of analog channels modulated in my house, and all but one are on UHF.
