Extremely happy - Running WSPR on a Raspberry Pi 4 driving an FT-817 with Yaesu SCU-17 sound card interface, I have been heard in Australia! (Anyone else getting spurious decodes with a similar setup ?)
Although I reported 5 Watts (37 dBm) in the transmission, the AGC was backed off and I have since measured the output power with an RMS meter at just under 2 Watts. I think it's time to build the QRP Labs Ultimate WSPR/QRSS kit or even a Raspberry Pi transmitter!
