Hi Gary,
Well, i see an offset of the Alpha trace by about 20 mHz, so your SL
session is not locked to a reference signal. Furthermore the Alpha
trace is suddenly disappearing. Why? There was no temporarely shut down
of the Alphas tonight. The two dashes in the frequency range of
interest disappear at about the same time when the Alpha trace
disappears. I would assume the dashes are local noise but i cannot be
sure of course.
Officially, just OE5ODL is transmitting on the Dreamers Band today. You
can check his and my grabber ( http://www.langwelle.at/ ) to compare
times and frequencies. My grabber is locked to GPS if the displayed
Alpha trace appears at 11904.7619 Hz.
Especially on 1 mHz and below it is recommended to have a stable RX. So
you may control if your SL session is locked to the choosen reference,
e.g. GQD/22.1 kHz (see attachment).

Hi All,
Last night I changed my SpecLab configuration to a version of
narrow 1mHz. I had a couple of traces on the screen when I checked this
morning. Comparing with the other grabbers they don't seem to match a
time-scale for visible traces there but are very close to the announced
frequencies of the Austrian operators.
Would you please look at my 9kHz grabber & tell me if they
are genuine traces from a known 8.970kHz test or otherwise.
I note that the traces appear at the same time as an increase in
noise & a peak in the Alpha signal.
I will appreciate any comment please. Please look at my grabber

Hi,
any chance from here (JN53EM) in your opinion? May be I could
have a try on next transmission (possibly during w.e.).
Regards
D.

Jacek, Ossi, VLF,
Congratulations! 699km in 3.8 mHz (suitable for DFCW-600) is surely a
new record for a fixed installed antenna on VLF by amateurs! Maybe
4X1RF could try to receive in "6000" as well?:-)

In 179uHz bandwidth the signal has abt. 12dB S/N! This signal has a
nice stable frequency.
