Re: ELF: Recent ZEVS activity

Hi Eddie,

yes I recall that many of your images were not visible, showing some upgrade advertisement instead. Now with the g3zjo.files.wordpress.com domain all look fine. 

ZEVS is slightly stronger before midday here, which seems consistent with the notion of more effective coupling to a shallower waveguide. Not sure if there's a summer/winter effect; at DL0AO we simply haven't been looking long enough yet, and I also suspect there may be a 6 or 10 dB TX power switching.

Best 73,

Was there a ZEVS capture in the blog post in the link above or was it
missing ?
Trying it locally I had a message about updating my Photobox account to
include third party images. Another demand for money after 10years of
free hosting I suspect. This could cause multiple losses of links in my
blog, there are hundreds of photos in that account.
I could spend hours mending holes. On this occasion I have located the
file and loaded it directly into Wordpress, all is well now.

The ZEVS signal in that capture can be compared with the live signal on
my Grabber today, a strength comparison with the 80Hz signal of unknown
origin can be made also, if it is indeed the same signal, now 0.1Hz
higher. In the post I talk of my suspicion that at this QTH the ZEVS
signal is much weaker in the winter months, the comparisons seem to
indicate that this is so. I will find out in 4 or 5 months time.
