ATV is a cool thing! And, thanks to you, I discovered there's more to it than I remembered from when I last read about it. The more common form of Amateur TV is SSTV[0] - Slow-scan TV. This runs in 3kHz (!!!) of bandwidth and typically gets transmitted on voice frequencies, since it can fit inside the max occupied bandwidth there. People transmit this on the HF bands, which can go world-wide! But... for FPV-purposes, it's pretty much useless. You're looking at something like 8-114 seconds/frame. But I had no idea that there's people doing Amateur fast-scan TV[1]. That's pretty cool too! I have no idea how readily available light and portable equipment would be for the 70cm or 33cm bands, but there is a bunch of equipment available for the 23cm (1.2GHz) band. As mentioned in my sibling comment... it's not necessarily legal equipment, and it's kind of just... available... from random distributors in China, but it works OK and you're not all that likely to have someone complain about it in that band, unless you happen to be interfering with their attempts to do the same thing :) [0] https://en.wikipedia.org/wiki/Slow-scan_television https://en.wikipedia.org/wiki/Slow-scan_television [1] https://en.wikipedia.org/wiki/Amateur_television https://en.wikipedia.org/wiki/Amateur_television
