RF & Software Defined Radio
Scan the entire RF spectrum. Build mesh networks. Intercept the invisible.
Software Defined Radio turns a $30 USB dongle into a receiver covering 1 MHz to 6 GHz — AM radio, aircraft transponders, weather satellites, trunked police comms, and signals you didn't know existed. Add Meshtastic and LoRa hardware and you can build off-grid communications networks with no internet, no towers, and no monthly fees. This is the technology used by radio astronomers, security researchers, ham radio operators, and serious RF engineers.
Every purchase directly funds independent physics research at the Golden Physics Project.
