Hi Giulio, well maybe they thought someone had annexed their frequency, a
little further north and they are laying claim to it again !!
It looks like a spider frying session again. ....a good clean out of the ATU
capacitor and the inductor turns. Maybe a little bit of corona cleaning of
the insulators as well. They have done this sporadically this year but the
last time I heard them was about May. I say this, because they are using the
old FSK format and I suspect when it is used in earnest they will be using
one of the more sophisticated mod. modes available on their new TX.
