Hi Stefan,
Really impressing! Rather interesting than "real" radio! :-) I'm
listensing since your mail appeared :-)
Wolf, is it your remote RX via VHF?
UHF - see previous post. In the 70 cm band.
As long as i don't go out of the city by at least 2 km i do not think
i would get such a clean spectrum...
Guess how far it is from the remote receiver (@DF0WD) to my home...
thus the yagis ;-)
Do you use SpecLab as a part of this system? Is the "Paul Nicholson's
hum filter" in use?
Yes and no. The hum is removed by the FFT-based filter, operating in
automatic multi-notch mode. All "stable carriers" (mains harmonics)
which exceed a certain (variable) threshold are removed, nothing else.
The older multi-stage comb filter sounded a bit too hollow because it
removed *any* harmonic of 50 (or 60) Hz, even if there was no unwanted
noise.
Unfortunately this cannot defeat the static rain (popping noise) which
is just beginning as I write this :o(
73,
Wolf .
