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...

73, Stefan/DK7FC

PS: I cannot remember a power outage here, is must be many years ago...
