One solution there is to pick a frequency(cell/military bands) where the FCC really comes down on transmissions that aren't authorized.
Or you could randomize it, the RTL has a pretty wide receive range.
- ladberg 9y agoIt's still always possible to just generate any radio signal close to the SDR at a low enough power that no one else can pick it up. Also, it would require special SDR transmitters, but you could in theory transmit on every frequency that an RTL-SDR could pick up (again, close by at a low power so you don't disturb other stuff).
- snops 9y agoA simple comb generator would fill all the frequencies nicely, and is very cheap compared to an SDR transmitter. I have no idea how useful the comb waveform is to "break" the RNG output though. Here is one for $99, I'm sure you could DIY one for less with reduced output power: https://www.tekbox.net/test-equipment/comb-generators/tbcg1-radiating-comb-generator https://www.tekbox.net/test-equipment/comb-generators/tbcg1-...
