Dave,

I did some tests today with Alan G3NYK at about 220km distance, to compare
the performance of different QRSS speeds under real band conditions. How
much better is QRSS60 than QRSS10 or QRSS3... or CW?
Find out our findings at http://www.wireless.org.uk/signoise.htm

Quite close to the results I got on a "closed circuit" test with a small
xmit loop at my own site:

Nice to know that these things work out in the real world.
