Hi Laurence,
This looks very interesting. I have never seen such a wideband window
(as i call it) from across the pond. You can even see DHO38 at good
strength, interesting!
Could you change the scroll interval to 1 minute per pixel? You have to
disable 'one pixel per FFT bin' for this. This would show us the daily
change of the signals just as on the lower picture on my VLF grabber
(http://www.iup.uni-heidelberg.de/schaefer_vlf/DK7FC_VLF_Grabber.html)
and would be even more interesting :-)
Will you run this RX as a grabber as long as you are not present in AK,
so as an automatic updating website?
I wonder that you can cover up to 26 kHz. Is your sample rate 52 kS/s??
So, thanks for all the infos and your interest. Beeing visible in AK is
a very big challenge but who knows... ;-)

heres a quick snap shot of what it looks like at 0225Z (thats still
daylight in AK) - you can see its pretty quiet now and Im yearning to
return home with my Loop antennae and M0BMU preamp, but as it is the
L400B LF Engineering probe is doing a good job up the now leaf less
Silver Birch trees -
Theres lots (lots!) of short term CW and MSFSK sigs that appear at some
strength (and we are close to HAARP!) and of course Ill try to do a
looksee during night time for Eu (which this one equates to but not
mutual darkness) and another one later when Asia Pacific/Alaska is in
the dark.
Hope this link works as its a new server http://kl7uk.com/AlaskaVLF0225z.jpg
