If possible, I tried to avoid that extra RF link, although not many TVs had a baseband input.
There used to be a lot that didn't have boxes, but connected directly to the TV tuner. The first cable system I knew of just had 12 channels, which were the same as the channels broadcast TV used (2-13). "Cable ready" TVs could get midband (14-22, frequencies located between 6 and
7) and newer ones also got superband (23-36). Until 2016, the cable here used those channels but you would need a box for digital (including premium channels). Then they changed to all-encrypted, so you couldn't get anything without a box.The first cable box I saw had a knob (35-position rotary switch). You had to take it in to the cable office when subscribing or unsubscribing channels.
BTW, "midband" left a gap for FM radio, which used to be common on cable. That corresponded to a few more TV channels, which were given the numbers 95-99. That is, the TV channels in order of frequency are 2-6,
95-99, 14-22, 7-13, 23-94, 100-135.
i never had that kind of cable box, although it looks a lot like a radio dial. I wish I had thought of that kind of remote.
I didn't need to hear that twice.
There's another remote I remember from the seventies that had only 3 buttons:
- channel up (there was no channel down). OK it you don't have too many channels.
- on and volume up
- volume down and off. There was no way to have the TV remember the volume setting when off
Looks like you made the mistake of assuming I was disagreeing with you.
Frequency is one of the measurements of waves, which may of may not be sound. You might notice we have frequency in AC power lines.
