Hi Markus and Alberto, yup my ball-park figure was a bit out....the old
mental arithmetic was not working too well then. My empirical tests showed
an approximately 10dB per decade improvement i.e. 3 sec to 30 sec is 10 dB,
which would tie in with your figures I think. Lyle Kohler's tests seemed to
show this line going close to the theoretical up to 120 sec dots. I guess
when it gets there the important thing is stability so you dont "shower" the
power into adjacent "boxes" so it gets lost in the noise.

This cold East wind we have been having recently really seems to have
produced a lot of noise. The lightning map shows that the only storms are
down in the central Med around Italy, but I have had to reduce the
sensitivity on my capture screen so that I dont think I will see John and
Warren it they active. May be we are getting noise from Jay's storm off the
Carolina coast

The swap from QRSS3 to QRSS10
is an advantage of about 3dB also. It does point to picking the right mode
for the path, and the conditions.
