My parents had one pre-scrambling. Late 70's. Power arm to tune it all the satellites. It was very high tech for the era.
Playboy Channel on sat F4 transponder 7 I believe. Good times for a 16 year old. I'd have parties at my parent's house when they'd leave town, and everybody would watch the thing in awe. It was hilarious, seeing girls react to seeing porn for the first time. Cable TV was in it's infancy back then in CR...they couldn't believe someone could get a hundred channels free, let alone porn.
I remember the US Festival, I found a live feed of it in the clear. Every band, every song. Canadian TV. Every pro and college sport broadcast there was. Wildcat feeds of satellite remotes from TV stations across America...crazy. Then there were west coast feeds of pretty much everything, so when I got home from work, I could still catch what was on 3 hours earlier...never missed anything.
My parents had a Zenith projection set back then...probably a 50" set that would rise out of it's cabinet. We'd stay up until dawn watching it. Mesmerizing.
The dish itself is still in my parents' backyard of the house I grew up at. Once scrambling came into play, my dad didn't want to pony up the bill to get a descrambler, so it slowly but surely dropped off to nothing free and clear by the late 80's.
