Coming home from work this evening, my curiousity caused me to wonder
what would happen to WSPR SNR numbers when using different antenna
configurations. I already knew that changing the input bandwidth
would change the numbers considerably, by changing the amount of
noise power going into WSPR for processing. So !! being the cat that
I am, I ran a few tests this evening, and came up with some results.

The data is too long to insert into this email, so I am going to try
it as an attachment. I hope it comes thru..

73 all, and have a great night
