On 6m JT65 I have been spotted in Poland several times. On 6m JT65 RX my best DX so far is Crete SV9CVY (2729km). On 10m WSPR I have been widely spotted in Europe since the early hours of the night. This is all Es. In my experience there is often Es at night. People wrongly assume this is mainly a daytime propagation mode. On 10m, WSPR can help "smoke out" short night-time Es openings.
UPDATE 1135z: A couple of spots recently from Finland of my 1W ERP 6m JT65 signals.
