10m and 6m Es

The sporadic-E (Es) season will soon be with us in the northern hemisphere. This usually peaks May to July, although there are openings less frequently outside these times. I shall probably return to 6m WSPR soon in the hope of catching some short-skip DX on the band. If I go on 6m, I shall return to the W5OLF beacon on 10m. This stand alone 500mW WSPR beacon runs 100% TX but randomises the TX frequency within the WSPR window. In previous summers I have been copied by 4X1RF (3519km) on 6m WSPR. Although the conventional wisdom is that this is multi-hop Es, I have my doubts. Es yes, probably, but some sort of chordal hop?
