During the activation of HB/AI-007 today, I tried some PSK31 on 20m and 40m. CQing for about half an hour got me 5 QSOs, two of which with known SOTA chasers (@HB9AGH and @SP9AMH, thanks!). One just needs to be very patient and persistent in calling CQ, compared to CW/SSB…
KX3 (5 W) with Android tablet and DroidPSK. Must get the macros set up properly for SOTA sometime…
