Interesting result Jim / Jay.
I assume that the figure that varies between -17 and -23 is the
receive value in dB.
Given the observation about local noise then it may be the case that
UK - USA could be achieved with 6 to 9dB less power.
This is a very efficient mode. The magazine 'Dubus' this quarter has
an article on communicating over the horizon with light by reflecting
light modulated by JT65 off the clouds.
Clearly various JT modes are being used at both extremes of the EM
Spectrum. No wonder it's creator also holds a Nobel prize for Physics.
Happy new year everyone.

The total number of decodes at this QTH was 14. Most occured
between 2348
and 0012, when there were 10 decodes out of a possible 13. The
first decode
occured at 2300 and the last at 0102. So these are over a similar
period of
time to G3XVL's reception, although differently distributed.
I think more decodes would have occured if the level of mains
noise here
last night had been lower.
