Two possible methods of creating a Channel 1 for your channel 1 TV set
If you have a vintage TV set with a Channel 1, you could do two things to feed it a Channel 1.
First method: Modify a TV modulator from a VCR. Depending on how it makes its channel 3 or 4, add extra capacitence to the oscillator it uses to make the video carrier. You don't need to mess with the sound carrier, as most of these things FM modulate a 4.5MHz carrier and then add it to the video to then be modulated onto the TV channel. You want to move that video modulator frequency to 45.25MHz. And the sound will appear at 49.75MHz. This is opposite of what you see on modern TV set IF strips BTW.
2nd method: Use a UHF tuner from an older TV set. But you need to shift the local oscillator from 45Mhz above the desired TV channel, to 45Mhz below the desired channel. Else the TV sound will be on the wrong side of the video carrier. But odds are that the image rejection of these things is so poor that a local strong UHF TV channel will make it thru fine. Tune it about 15 channels higher than the desired channel, like channel 46 for channel 31. Or channel 65 for 50. Or 83 for 68.
