The CRT enthusiasts on Reddit would love something like this, but for analog TV channels.
Something that people ask occasionally is how to use their vintage TV's tuner to receive digital TV. But they don't want to tune it to channel 3 and then change the channel with a digital TV box; they actually want to change the channel with the old tuner. The current advice seems to be to spend $hundreds to get an analog CATV head-end, and a separate digital tuner for each channel, but I've never heard of anyone actually following through and doing that.
- brk 2y agoIt’s not that hard or expensive. CATV analog modulators were common in the past. I had 8 in-home TV channels until our cable company went digital.
- jes5199 2y agothere are cheap, new analog TV modulators/broadcasters available on ebay now
- argilo 2y agoIt's definitely possible to transmit multiple TV channels at once, and I have experimented with that in the past. Since TV channels are 6 to 8 MHz wide (depending on what part of the world you're in) there are practical limits to how many channels can be transmitted at once. Consumer-grade SDR boards are limited to about 56 MHz total bandwidth, which would be enough for 7-9 channels.
