Interesting. I didn't know about that. I suppose we need to develop 
our own tools from within the LF community as we are too small to 
attract attention from without.

I'm trying Windows 7 compatibility mode with WSPR-X. It has been 
running about 10 hours so far and decoding K3RWR every time.

The rain has stopped so today I can look at my antenna coil and 
maybe start transmitting again if the coil is OK. I will start on 
WSPR-2 again but might switch to WSPR-15.

73,
