WSPR on 30m to California

One of the best features of using WSPR is that you don't have to be present for it to work ;o)
It's just a case of setting it up late at night, head off to bed and then when you wake up in the morning, you just look at the WSPR website and check out the fancy maps to see what you heard.

I've listened a few nights recently on 30m but last night seems like it was good for California and the west coast of the USA. I heard 4 stations in total....
K9JM.....5w......I was the only European station to hear him.
AF6ZO...5w.....I was one of 4 in Europe to hear him.
KC6KGE.....5w......I was one of 4 in Europe but seemed to be the most consistent
K7LG......1w........I was the only European to hear him. This was the same as back in 2009.

Considering that I am just using a doublet antenna for receive which is just 4 metres above ground, it's not like I have a better antenna than anyone else in Europe. I presume it must be the location........i.e. the North West of Europe.
