Gary - thanks - 
 
My tx freqs on WSPR were (Im still on till dawn AK time around 1818z for AsiaPax)  nominally 475.811 ("dial" USB 474.2kHz +1611Hz) and 137.612 (136kHz +1612Hz)
 
The 476.180 QRSS window was a suggested window for Eu operation reception over the next few days and not one Im transmitting on Im just looking between tx periods.
 
 Viz Aurora overnight so not expecting much except larger electricity bill :-)
 
Cheers
