Hello Gerhard,
I've already seen that your LF grabber was OFF and is on now again.
About VLF: The Drain-Source voltage across the first FET should be
arround 5.3 V if your supply voltage is about 13V. So you check easily
if something is wrong. Hope you can fix the problem soon although
activity is low these days on VLF.
Very noisy time! My "60000" window is now almost complete filled and
shows time back to March, 12th. One can clearly see the QRN change now
since middle of April. The noisy part becomes broader and stronger :-(
Anyway there is a minimum in the morning and sometimes at low levels...

PS: I cannot remember a power outage here, is must be many years ago...

Hello LF/VLF!
Unfortunately there was a power outage here today and my grabbers went
down around noon. Luckily this really only happens very rarely in
Austria.
When I came home about 2 hours ago, I thought it wouldn't be a big deal
to restart the computer and bring the grabbers online again.
This was true for the LF-grabbers, they are working as usual as far as I
can tell now but the VLF E-probe doesn't deliver any output signal
anymore. Obviously this is a Hardware-Problem caused by the power outage
or the thunderstorms we had here recently.
So VLF portion of grabbers will be down for a while until I will have
the time to repair the E-probe.
