Works A brief video to show how Multipsk can decode NAVTEX transmission on MW bandReceiver SDR AFEDRI+ Magnetic Loop Antenna An SDR is a radio that sends that raw signals to the computer without doing any sort of demodulation and (if it transmits at all) generates signals by taking discrete signal levels from the SDR Rx/Tx software for Airspy, Airspy HF+, BladeRF, HackRF, LimeSDR, PlutoSDR, RTL-SDR, SDRplay and FunCube - f4exb/sdrangel. Stuff for RF applications are usually super expensive but with SDR you get very sophisticated solutions for little money. Board index. With these tools you can schedule running commands, but that's not really a RTL-SDR problem then, more a sysadmin problem.
