One good idea would be to automatically reduce power when beaconing WSPR to avoid stress on the PA when the PA can be on continuously for almost 2 minutes.
UPDATE 1540z: Success! My first transmission with the QMX+ (10m FT8) resulted in 18 spots across Europe. This was using CAT control. I have a lot more to learn, but this is a good start.
UPDATE 1651z: 3 QSOs in quick succession! All called me on FT8. In all, spotted by 49 stations.
UPDATE 1754z: The map shows the stations spotted on 10m FT8 RX using the QMX+.
