Thanks to all who sent me advice re
spectrogram.I have now solved the problem and of course it turns out to be
"finger trouble",but all the information and advice was most
valuable. I shall now be looking for qrss signals in order to check out my
equipment,before venturing on to the nezt stage.One thing is that I can use my
Racal 1792 Rx !
I am quite sure that we will need the additional
sig/noise afforded by qrss if we are to achive a transatlantic QSO. I am reading
IEE reports of long distance tests carried out in the late 1940s and will try to
sort out some figures re signal strengths to be expected on this route. 73s
