I have been following your
experiments with interest. Looking at the two grabbers, Stefan was
sometimes visible in Moonah but not (or at least not much) in Orford.
Not sure whether that's due to some intrinsic noise in the Orford setup
(then you might end up making things worse by adding in Orford data),
or Stefan being weakened by the extra distance (then Orford data would
still be useful to partially null QRN).
Weakened by the extra distance of 27
km (+ 0.16 %) ?? :-)
No i think i am weakened by some Q decrease of my loding coil and that
building,
https://dl.dropboxusercontent.com/u/19882028/20130913_161536.jpg ,
which is now built up in 30m distance to the antenna :-(
Seems i will need a 3 phase PA (already thought about a H bridge out of
STW25N95K3
:-) ) if i want to hold the level :-) Let us make a reference test
(>=! 200 uV/m) when they finished the buildings and dismantled the
cranes...
Or, it is simply a worse propagation than last year??
