After no activity overnight, I switched everything back on 10m JT65 just after 0930z. So far no spots at all again.
UPDATE 1100z: Still no spots on 10m JT65 here so far today.
UPDATE 1242z: IK8TNG (1639km) has spotted me be Es on 10m JT65.
UPDATE 1646z: Three Es spots so far on 10m JT65 (2 Italy and 1 France). No real DX seen yet. As there is no Es towards S.America, I think it is unlikely there will be any Es joining with F-layer today on 10m JT65. Let's hope I am proved wrong.
UPDATE 1912z: Well. I was wrong! I have spotted stations in Paraguay and Brazil on 10m JT65 this evening already. I do not think this was Es related.
UPDATE 2018z: With CU2ZG (2572km) in the Azores just spotted, and spotting me, I am wondering if the South Americans are a linkage of Es and F layer after all? I have recently also spotted a couple of LUs on 10m JT65, with best DX LU1ECF (11223km).
