It's based off of amateur radio yes. As a ham this is actually really really cool. A Raspberry Pi is able to transmit detectable WSPR off of it's 10dBm output from the GPIO and an antenna if you have a callsign and want to try it.
There is a database & map of current WSPR activity on all amateur bands. I frequently use it for propagation indicators.
