Hi Stefan yes it looks like that was the case. As to the Iceland grabber it
is only one hop from you I guess so it always receives a good night-time
signal. One must remember that the display of grabbers is very non-linear
there is only about a 3dB change in signal strength to go from T to O and
then little obvious change until it "dog-bones", so they are not ideal for
seeing the detail of fading on a signal which it at least O, except when it
drops right out. You are also seeing not a real signal strength but more a
S/N display which depends very much on local noise conditions.

Great work keep it up!

Best Wishes

Hi Alan,

Yes, ther is strong QSB at W1VD. I was watching his grabber in the last
hour but my signal was lost then. Anyway i saved the cpature i saw when
i first saw my signal. Now the capture is here too:
http://dl.dropbox.com/u/19882028/LF/grabupload1.jpg
QRSS-10 is relatively fast and it would be interesting to have a beacon
running in that speed. Will first have a look on the TX system since
there have been strong winds here.
I hope for better propagation soon.
TF3HZ seems not to care about propagation ;-) His grabber always shows
very good signals.
