Andre: Just to add to the confusion (?) let me add the followiing,
based on extensive daily monitoring of AMRAD WA2XTF/12 at Front Royal
Virginia, a distance of 324 mi ( 520 kM). The WA2XTF signal appears
with great rugularity before local sunrise and is solid copy with no
QSB noticed through the observation period. At present ( 1545 EST)
(2045Z) the signal is audible and solid trace at the same time using
ARGO and Spectrogram. QSB has not been a problem, and the signal is a
steady and solid reference as I experiment throughout the winter with
different antenna configurations / preamps.
I believe you use a 1500 foot ( ~500m ) longwire - so I can certainly
guarantee I will receive your signal over a 12 hour period, well past
sunset. Later ( 2100 EST) 02Z ) the signal is very weak and disappears
normally until re-appearing with the sun !
For your information.

Have heard OK1DTN for the last 2 weeks several times with good signals,
from 559 up to 589. But so far I always called him in vain.
Most of the time he has a fair amount of QSB on his signal (compared to
others at the same distance).
I wouldn't be surprised if he was running a long wire antenna, I getting
the impression that stations with relatively long wire antennas have more
QSB than those with small toploads or pure verticals.
Could it be that long wires radiate at steeper angles and thus produce more
skywave ?
