  • I’m not much of an expert but it’s basically low power UHF radios that use a particular waveform and FFT process to decode signals that are well below background noise. My radio regularly picks up messages with an SNR -10. I like it to the GPS system’s algorithms.

    The main drawback is that, because they’re low power, you have to have LOS between antennas.
