Gus, Your WSPR signal peaked at 0dB S/N just now, suggesting 2mW ERP could have been copied here.

Gus,

You 1W ERP WSPR signal is now up to -7dB with me, implying it could be some 20dB weaker and I'd still be able to copy you i.e. 10mW ERP. Remarkable on my system which is just 15m of untuned endfed wire into the standard FT817 RX.

With the WSPR log tonight I can see exactly how propagation has been changing every few minutes between UK and Sweden.The power of WSPR well demonstrated for any doubters here.

Am listening for your 504.5kHz WSPR now Gus. Will continue all evening. Just a hint of a trace on the screen but, if this is you, too weak to decode yet but it is getting stronger - a few minutes time maybe.
