Re: LF: Wasilla Alaska VLF - offline

Hi Laurence,

 

if I had only one to choose from, I'd definitely opt for the slowest "60000" window at 47 uHz. Depending on antenna orientation, this would definitely give Scott a chance, or perhaps one of us over here. Would an onnidirectional E-field work as well for you as the RX loops?

 

Running the second FFT for the Alphas nearly doubles the CPU load, so you may want to skip that.

 

Thanks for the great work!

 

Best 73, 

Markus

VLF pre Eu dawn signals are way down from mid winter Stefan, but that signature increase on DHO38 signal between 0500 and 0700Z is still there. Looks to me like a mid winter opportunity only on this 2 x Auroral oval path at this range, but I could be mistaken. The loop is tensioned from movement by an ice screw in the lake and given the increasing temps Im sure it will come dislodged sooner than later - the other side is tensioned to a Birch tree so I dont think it will move. If Scott warms up his #2 Ill have to get someone to turn the array as hes in a Cosine null at the moment.
 
Ill take a look at the processor and see what gives but welcome any direction on speeds/fft longterm so I can leave one or two screens up longer term without frying the proc..
 
Not sure if Ill be in the same location by next winter :-(( Your going to have to work out how to get an antennae up and stable in the latter part of the of the Eu night for this path to work me thinks :-)))

Hello Laurence,

No hope for the end of the season? Maybe you are right, unfortunately. But you'll come back in the next season, isn't it? :-) Or maybe just reducing to wideband and 6000 or so? A pity...
But thanks for the service and the intersting location to watch and sharing the optimism!!
Maybe we'll see what can be done in Greenland, that's a next step into your direction, about...

73 and good luck,

Stefan/ EI/DK7FC
