Hi all,
Murphy paid a visit at last moonrise, in form of wind, clouds andfinaly a
dead LNA.
I could not see any traces on the waterfall, but at first I blamed the
windy conditions that made tracking difficult, the dish was very shaky, and
I coudn't see the moon, so no aiming reference at all. After the moon came
out of the clouds I could finally verify the pointing, and it was fairly
good, so I started to look at the rest. Found the LNA not working properly,
but replace it in the dark with wind gusts peaking at 30+ knots was quite
difficult.
After the change everything was back to normal and I've completed several
QSOs.
The first stage of the LNA is indeed dead. No clues about the cause since
everything is well sequenced. Maybe static charge by the wind?
I will be back with JT65 at moonrise but give some time to CW requests too.
Let's hope that Mr. Murphy stays clear, no more spare LNAs.
Best 73. Giulio
