Laurence, Daniele and other Low watchers
I can confirm the reliable daily transmissions from ZEVS are at 0800
UTC and 1700 UTC. Others have been seen and occasionally the
breakfast and tea time transmissions have been missing.
I recently have had high noise levels causing problems with seeing
ZEVS on my Grabber http://g3zjo.bplaced.net I will take a look at
the filtering again to see if I can improve it, although it may be
summer noise levels. It is a bit bizarre looking at signals which
are deliberately well down the skirts of the high pass filter in
the E probe I admit.
I had a few of days at a remote site last weekend and found it
interesting.
Firstly the carriers on 16Hz, 32Hz and 64Hz and some others which
are obviously not mains related, and I suspect Daniele's 11.7Hz
nasal cilia resonant frequency do seem to be from local sources,
they were non existent at the remote site.
Secondly I looked at the stripes of enhanced noise which cause
problems when trying to identify Schumann Resonances on our urban
set ups and did some further tests back at the home QTH. They seem
to be caused by ringing in the 600 Ohm transformers we need to
isolate the Desktop computers we tend to use. I tried cheap
transformers and Mil Spec and they are the same.
At the remote site it was such a pleasure not to have to peer
through these to see look for resonances and have them ruin
captures.
