Uwe, Peter and other VLFers -
I ve shoved the very slow 8970 on the following snappers.
http://kl7uk.com/VLFAlaska.html VLF only
http://kl7uk.com/Alaska.html MF LF HF and VLF dependant on my viewing/requests
I see some odd goings on over the past 24hours around 19k, looks like some stepping stones going on - and it looks like the Alphas are doing some strange stuff too. I am on my standby soundcard which has a little more roll off at HF after my Realtek died.
No signs yet Uwe but over the Pole hasnt been good on any band for a couple of weeks.
I still need to figure out the best FFT size and "decimete"r ratio as Im still a bit clueless there - I need to do some more reading -
Is it better to have a longer FFT input size and smaller decimate or say smaller input size and larger decimate :-) ?

O.K. thanks for info Uwe.
You don't have to say sorry :-)
It learns us again that a stable signal is very- very-
veryyyyy importand.
My 424 uHz grabber shows your signal and
drift clear with connected pixels
My 47 uHz grabber shows no connected
line/trace anymore.
Nice to see that the Frequency Error callibration
works so well in Spectum Lab.
It seems that the Soundcard here is also rock stable
with help of that SR cal function.

No, Peter, my control capture shows the
same.
Sri for that.
Seems the GPS ant got
wet.
I have to find
out.

Hello Uwe,
I'm not sure, but it looks like your
generator is not rock stable anymore since 19h45 UTC yesterday (1 Feb
13)
It did drift down about 0.003
Hz. (Ha ha.... 0.003 Hz)
Also possible that the trouble is here
ofcourse...
Now (09h48) drifting back up to
8970.022 Hz
