ARLA/CLUSTER: Raspberry Pi com WSPR transmite até 250 MHz

[João Gonçalves Costa]

Raspberry Pi as WSPR transmitter up to 250 MHz

Guido PE1NNZ has released code that he says enables the Raspberry Pi to operate as a WSPR transmitter at HF and VHF.

Guido has modified the WsprryPi code originally developed by Dan Ankers MD1CLV. He says the Raspberry Pi requires just a Low Pass Filter (LPF) and antenna connected to the GPIO4 pin in order to function as a WSPR transmitter.

The PE1NNZ code and binary is available at
