Hi
This is an observation on overnight TA conditions from across the pond.
There appeared to be a wipe out of TA signals around 0500 utc. I do a
plot of carriers on each frequency and nearly every frequency shows
audio disappearing at around that time ... almost as if a plug has been
pulled.
It would be interesting to learn if anyone 'on the other side' noticed this.
I'm attaching a plot of 1430 kHz, which is typical of just about every
frequency The white/blue fuzz around a carrier represents audio present
and you can see what happens at 0500.
