I had to look up the 83, but I knew it was way more than 45. When I lived in NYC in the early 1980s, I watched wrestling on 9 and 47, and music video programming that was simulcast on channels 67 & 68. They later changed their format to home shopping.
Thats cool.
I had 4 stations. All of them VHF. 2,6,8 and 10.
2 was PBS. the others were the majors.
I was much better off back then. :^)
