This depends on distance, frequency and the
diurnal variation of ionospheric height (the ceiling of the
waveguide), resulting in constructive or destructive superposition of groundwave
and one-hop skywave. 9 kHz propagation between Stefan and myself
(also about 180 km) exhibited the same minimum at noon. On the
other hand, 400 km to OK or OE were usually best
around midday.

Hello Uwe, VLF
I did try to find the signal maximums since ~3
Feb.
Here they are...
06h17 15h40
????? 16h20
0730 17h38
????? 16h00
The ???? are because there was interference or sort
of.
Looks like there are some maximums around sunrise and
sunset.
Around 12 h UTC the signal is the weakest in my
oppinion.

Hi dreamers,
the TX was off from abt
1230UTC until 1440UTC today
because
1)
my XYL was working in the greenhouses (metal framed)
and
2)
I took the advantage repairing the aerial (one of the
anchorage ropes didn’t stand the sparks).
