Back on 6m - missing out on DX with WSPR?

Since around 1500z I QSYed back to 6m from 10m. 6m activity levels from DX stations are still disappointingly low: only last evening PE4BAS was working WP4 (Caribbean) with just an FT817ND (QRP) and V2000 vertical using JT65 digital mode.  See http://pe4bas.blogspot.co.uk/2014/06/magic-on-magic-band.html .

At the moment WSPR is not the best mode to get DX, which is a great pity, as it is probably the mode that works best with very weak signals.

Since 1500z only G4IKZ (18km) and G0OQK (98km) spotting me on 6m WSPR. No sign of any Es.

UPDATE 1855z:  a short while ago G6AVK was spotting me at -26dB S/N at 78km. Still no Es here.

UPDATE 1900z:   Sunspot count is 87 and 20-30MHz propagation forecast now only "fair". It was "normal" earlier in the day, so conditions for HF F2-layer propagation have deteriorated.
