It is now 0935z. Although I have been on TX for about 20 minutes with my 500mW W5OLF beacon, no spots. I guess Es is a bit more "hit and miss" now that the season is ending.
UPDATE 1110z: So there is life! Spots by HB9TMC (905km) has spotted me, but only twice.
UPDATE 1344z: GM0UDL (659km) also spotting me. I have noticed before that more northerly stations appear more commonly later in the Es season.
