I'm back for an update with my station. Just tonight during a live broadcast on WHAR, I sent out an SSTV (slow scan television) image on 92.9 FM. I have never heard of anyone else doing this before so I said why not? And it worked beautifully.
Experimenting with radio is what we all love to do. You should try it!
Come to think of it, I'm not aware of any SSTV activity in the Longwave and Mediumwave bands either. Maybe for giggles I'll start sending a daily SSTV transmission late at night.
I also wonder if the FM band is capable of more than SSTV, I would imagine the SSTV picture came out near flawless.
Yes, the audio bandwidth of SSTV signals is such that SSTV works with any system that will pass communications grade audio.
I'd think that beyond part 15 levels the FCC would have a COW if some station even tried that (With their knowledge). Then again their was that commercial station that recorded Emergency Tones for some type of skit and it caused all sorts of issues. Hopefully their would be no EAS systems set off by the SSTV tones. Some of the older models who knows.
An SSTV transmission will not trigger any EAS box. As far as I know licensed broadcasters cannot transmit FAX or SSTV, though overnight FAX broadcasts used to be very common waaaaaay back in the day.
For a short time you could receive newspaper articles by fax over your AM radio. And yes, way back when...
