Stefan, I have been monitoring the ZEV´s just for fun. The current status is a steady carrier on 82Hz so a good chance to test your equipment Two transmissions a day, morning and evening You can watc
Carrier comes on and off at irregular times each day. Here is a plot of 82Hz over the last three days http://abelian.org/vlf/tmp/zevs-140829a.gif (1.67mHz bandwidth, 10 minute samples) It's a strong
Thanks Paul, Yes, it should be easy to copy ZEVS in a quiet location. But in urban locations there is no chance. So i'm looking forward to play a bit in the garden this weekend :-) I will also get a
As part of my checking that everything is OK and ready for the next tests on ELF/ULF/SLF ? I have my Grabber http://www.g3zjo.talktalk.net/vlfgrabber.htm Live on Wide and ZEVS. ZEVS is showing a good
Hi Eddie, LF group, it looks like despite very strong 50 Hz and 16.7 Hz harmonics, I can still receive useful ELF signals from my Marconi (currently only 3 m above the roof) with a simple BF245 sourc
Hi VLF friends, Nice to see there is some interest again in the very low frequencies :-) Yesterday i checked the VLF spectrum in my graden for the first time. I tried to detect ZEVS and took a 2 hour
Hi Makus, Stefan, All Very jealous here of Markus' Schumann resonances, the response of my E-Probe filter necessarily cuts off at that end. I did try different responses a while ago and if I let much
Eddie, Stefan, yes I was surprised and exhilarated to find the Schumann humps along with the 82 Hz signal. The quest to see those always seemed like some kind of holy grail regarding low frequency wo
... been scratching my head about that 10 dB deficit. Errors in the scope measurement, or in the effective height estimate? There are uncertainties but it seems hard to explain a factor of three. Or
