... It's clearly visible on Google maps satellite view, but the images have been airbrushed from Streetview. Suggests that somebody in the military is a bit...
Hi John, I agree with Alan's opinion that sky and ground wave signals will be nearly equal in strengths at ~1000km of distance. That's not always a bad thing...
Hi Peter I have wondered about the effect of tilting the loop. I know that works close to (100 to 150km) but I claculated that the arrival angle of daytime...
Hi Santo, ... Will be considered in one of the next versions: A simple readout cursor following the mouse when hovering over the plotter's graph area. ... ...
If you read my original post I asked what happened to NML's signal on 25.2 kHz., not the location. I know where NML is physically located. I used to be able...
Peter: Unfortunately at my location I have a horrific amount of constant background noise. The loop orientation that I use is the one that minimizes the noise...
Alan: Yes, I suspect you're quite right. I may be just a wee bit too close. However group 1476 hasn't thrown up any X class flares yet so I've yet to see how...
Here are the coordinates to NML; copy-and-paste these into Google maps and you'll find it with no problem. 46.365993,-98.335627 Â However, I don't think the...
Our old friend ZEVS on 82Hz has been extra active this week with Data transmissions more often than the previous 0800 UTC and 1700 UTC which were the reliable,...
What is the big circle on the map? A fence??! 73, Bill, WA2DVU From: VLF_Group@yahoogroups.com [mailto:VLF_Group@yahoogroups.com] On Behalf Of Ken Sejkora ...
If still of interest, NML (25.2 kHz, La Moure, ND) was not heard this morning at 7AM (local) at my QTH (Central NJ, grid sq FN20sd). Normally this station,...
Hi John, ... Yes, it's down. I can see NML, 25.2 kHz, well during late evenings until next early mornings around 6-8 utc. Sometimes weak over the whole day. No...
Eddie, thanks for setting up your grabber again. My other source is Renato's grabber which has to struggle with a much longer signal path. Your analysis of...
I took a look at the street view and you can clearly see the tower from the road to the south (Hwy 13?). The Google images are not clear but you can make out...
Bill: I'll take a stab at your question. I don't think it's a fence. The antenna is an insulated vertical with a huge capacity hat. The capacity hat wires...
NML seems to be back on the air on 25.2 kHz. As of yet it is only a carrier with a couple of constant sidebands. No keying of the signal. They came back on...
Hello Manfred I will keep My Grabber on ZEVS for as long as possible. I do tend to vary the active windows at times. I have added zevs 1205_2012 to my G3ZJO...
What a pair of beauties, Eddie. Impressing the four-message one. Couldn't be cleaner. I've uploaded a gif file to the beauties folder showing the enormous...
Hello people, getting some weak whistlers this evening, but this time on my VLF loop. Not sure if they are really weak or is it my loop antenna that is merely...

... Recent activity has been better (as usual) at more easterly longitudes. In last 36 hours, about 3800 whistlers at Bielefeld (52N,8.5E), about 750 in UK...
Paul, there seems to be cutoff with my receiving loop but I'm not sure if it's ionosphere or my loop/preamp characteristic... it looks ionospheric cause, ...

Greetings list, When I transform my registrated data of SID-recordings into Excel-graphics, I do encounter a annoying problem: The value shown on time-axis is...
Hi Robert this may not be the right answer but I had great difficulty at one time getting Excel to plot the actual data. When doing a time or XY plot it seems...

... Hi there, it's not exactly what you are asking but I'd suggest using gnuplot instead od MS Excel. You'll have to learn how to define a plot with what you...
Hi Guys, here's a man-made signal that has intrigued me because there's probably a fairly complex means by which a central air conditioner would produce such...

I think such a frequency modulated signal could come from a motor which drives a non-uniform load, eg something reciprocating like a piston. The period is very...
