The season came off to a slow start, as I was late erecting the FM antennas. Also, it wasn't anywhere near as productive as the 2020 season, except maybe the last part of July and the beginning of August. And I must admit there were openings I didn't bother to check since it appeared quite predictable which stations would be heard.
I did hear a new country though. Iceland was heard several times, although limited to the northeastern part of the country.
Next year I think I will change tactics a bit. To the south, the one-hop Es possibilities are more or less explored the last 3 years. So it may be more interesting to point the antennas to the west-northwest, and to the east. Iceland (and beyond) may be interesting, as would Siberia, Kazakhstan and Xinjiang.
The SDRPlay RSPdx SDRs work well, although my PCs limit effective sampling rate to 6 MHz each. For the same reason, the Elad FDM-S3 can't sample more than 12 MHz. So I decided to focus on the lower part of the FM band.
The SDRs made 24/7 IQ recordings, and I spotted openings by examining continuosly saved waterfall images. HDSDR and SDR Console were my tools, together with two 8-element antennas from InnovAntennas, and splitters/preamps from Cross Country Wireless. And a number of 8-TB hard drives.
