Hi Markus,
its true, this moment our cat is terrorizing his neighbor fellows.

Snatches of sunshine here around.

GL, Uwe/dj8wx

Cat alarm!

 

Today noise and QRM is very low here, and now there's a clear trace on my grabber

http://df6nm.darc.de/vlf/vlfgrabber.htm

... about 13 dB SNR in 0.47 mHz, and even faintly visible in "600" 3.8 mHz. Better than ever!

 

May well show up on Eddie's grabber again

Best 73,

Hi Jim,

 

didn't see the cat myself, he was betrayed to me by others

Apparently Uwe's cat's carrier was on air today from 17 to 21 UT, but not this morning. Unfortunately my own grabber is too noisy to catch much of it, except for the odd bright pixel.

 

73 and good luck,

Markus (DF6NM)

Uwe and Markus,

 

Was he out from about 02:15 to 03:15? I?m trying to interpret using Markus? grabber.

 

Hope springs eternal here that with management of natural noise, continuous monitoring and luck I might detect TA signals. I was making receiver modifications for noise mitigation (i.e. receiver off) approximately 01:00 ? 10:00. If I had known that it wasn?t raining at 0200 I would postponed my receiver noise modifications.

 

I am running multiple windows at different bandwidths (thanks everyone for your previous advice on this) to enhance the chance of detection with arbitrary on/off (rain/dry) periods.

 

73, Jim AA5BW
