Revolutionizing Radio Communication: Pico-WSPR-tx Transmits Solely Through Software
The pico-WSPR-tx, developed by RPiks, is a low-cost radio transmitter that utilizes a Raspberry Pi Pico and a GPS receiver to encode and transmit data to the Weak Signal Propagation Reporter Network (WSPR). By using the Pico's GPIO pins for transmission, the beacon design eliminates the need for additional hardware, making it an affordable option for testing radio propagation conditions.
