Dude, it's been feasible since the 1960's, and cheap since home video equipment became common in the 1970's. Old fashion NTSC signals are just simple AM modulators, dirt cheap and dirt simple to build. (OK, I admit that a VSB transmitter requires an interesting filter, but not out of the question, and more-or-less optional unless you are running high power.) Also, some hams have been doing NTSC over FM for quite a few years (SITN used to run over FM).
Modern digital video is also pretty much plug-and-play these days, although building a transmitter from scratch with a half dozen transistors isn't a thing.
- nickpsecurity 10y agoYeah, RF is out of my expertise a bit. I've been looking into non-digital hardware stuff for a few months to a year now. I figured I'd get some useful feedback. Let's flip it in a different direction. What have you found to be the most interesting and noteworthy applications of FPRF for a hobbyist and/or manufacturer? What examples should I pass along to people wanting to tinker with them or push the envelope?
- dbcurtis 10y agoWell, not quite FPRF, but people have been using rooted Androids to build RYO-Stingray-Detectors. I'd love to see this become ubiquitous. With a nice API and some Google map-fu you could crowd-source a real-time nationwide map of Stingrays in operation. Perhaps an FPRF board like this would simplify the RF side of that.
