Many tnx for info and update (SM2CEW) .
My personal QSO-quote was 93:7 (random:sked), of which random was much more
effective. Sometimes I worked someone ramdomly after many unsuccessful skeds
Ok, one may say, this is (was!) done by a 8-yagi station.
However, when I was QRV portable-EME in several different places then
my quote was still 90:10 (random:sked) on successful QSOs.
My last p-activity (SV8/DL5MAE , 1 yagi, no elevation, new-moon +/- ,
not more than 400W, no rx-filters , local_QRM ) resulted 9 random
QSOs in 1,5hrs operating time.
So I dont know how someone can say, that CW OPs are cheating, although the
majority of QSOs is done randomly.
If I watch the loggers (N0UK/ON4KST) I may get the feeling the opposite is
the case...
