Oh my ! 2E0ILY is making improvements, I best set to work building 
that attenuator to protect my receiver... ;-)

I realize one cannot directly compare S/N reported by different 
modes in different software but I had Chris up to -24 on WSPR2 mode 
during the quiet winter months. I have reason to believe we missed 
the best of season when it could have been a few dB more. I suspect 
we won't see those numbers now due to increased QRN and less 'deep' 
common darkness at this time of year but who knows.

I really appreciate the effort put forth by all who are transmitting 
on LF. I am having much fun receiving signals from across the pond !

I wish I had some competition over here in the receiving department. 
I have no idea how I'm really doing as there is no one to compare 
against. :-)

I've got a full summer's work to do on the TX side but if I get a 
chance I will put up some more RX antennas too...
