TAPR now offers its popular Raspberry Pi QRP TX Shield for WSPR in three versions: 20, 30 and 40 meters!
Nowadays, one of the most impressive QRP modes is Joe Taylor, K1JT’s WSPR (pronounced “whisper”) mode. WSPR stands for “Weak Signal Propagation Reporter.” Programs written for WSPR mode are designed for sending and receiving low-power transmissions to test propagation paths on the MF, HF and recently, UHF bands. Users with Internet access can watch results in real time at wsprnet.org.
TAPR’s QRPi board (or “shield” as referred by the community today) is an inexpensive way of turning a Raspberry Pi single-board computer into a QRP transmitter. The QRPi comes to you assembled and tested.
