By coincidence, the same signal ('VLF6'
from Spenge near Bielefeld) was analysed here before the
Ogg/Vorbis compression / decompression.... directly tapped off the
local FM link... result: With a ~ 1 mHz, also no trace of Henny's
signal. I may have been a bit too optimistic by selecting this FFT
resolution..
All the best and thanks for supplying the test signal - will try
again on the next occasion with a longer FFT window.

Btw, site of the 'natural radio' receiver ('VLF6') which streams
to the internet via Paul Nicholson's server since a couple of
years:

Henny,
thanks for leaving the power up
this afternoon. I am quite aware of the acoustical noise
problem, the situation is very much the same here. I have
tried to cover the coil but the high voltage uplead to the
antenna seems to be beeping as well.
This afternoon I ran the 0.477
mHz VLF grabber here in Nuernberg, unfortunately no trace
here, maybe I started too late when the qrn was already coming
up.
In addition, I made an experiment
to extract 0.477 mHz spectrograms from Paul
Nicholson's timestamped Ogg/Vorbis streams, fed by Paul in
Todmorden and Wolf in Spenge (rawtcp://67.207.139.49:4416 in
stereo). Their
GPS-derived timing and samplerate are very accurate. Sharp
spectral lines could be obtained from the Alpha stations on
11.905 kHz, so phase coherence miraculously seems to be
preserved through the audio compression process. Then today I
tried to pick up your carrier in both feeders but
unfortunately no joy here either, yet.
However I have to say listening
to the streams is well worth it anyway, you'll be rewarded by
numerous tweeks and occasional whistlers tonight.
Best 73,
Markus (DF6NM)

Hello Marcus,
I have to make an appointment
with the neighbours,they can here the 8.270 khz tone ,so
transmit maybee once in a month or so,now i will transmit till

Time to QRP 50% Henny.
Lets see if that works to!
Daily visible here, also rightnow.
