Hi Stefan
which again confirms that this path is less (not?) affected by solar
activity. Same as on the path to VK..
I wouldnt quite say that :-)) the Dst was rising rapidly and was
nearer -30nT over that period. The YV route my be a little as 3 hops
with a couple of "salt water bounces", as Markus says you nearly made
in the previous night at a Dst of probably around or slightly above
-60nT. By comparison the VK route is probably at least 5 hops so you
are looking at 25dB more.....certainly need a little wind behind you
:-)) but there may be more opportunities than just at the equinox,
though the darkness period is most advantageous then.
Unfortunately Dst doesnt predict a good result, rather the better
probability a result. There are a confusingly wide range of results
even on a high Dst night.
Well done on these tests! It certainly is good to see marginal
conditions probed, and a few "urban myths" tested :-)) The deep
search has certainly enabled us to peep under the normal noise barrier
and see what is actually possible in these paths. If you dont see
anything you dont know whether the signal it is a couple of dB below
detection or -100dB in other modes.

Martin, LF,
Most amazing. There were even 7 decodes last night!!!

This is the first night and all night before produced not even a
single decode.
DST levels were arround -40 nT
(http://lasp.colorado.edu/space_weather/dsttemerin/dsttemerin.html)
which again confirms that this path is less (not?) affected by solar
activity. Same as on the path to VK..
Thanks for the receive site in Venezuela!

LF!
Just a few minutes ago i saw the first decode of DK7FC on Martin's
YV7MAE LF
OPDS monitor in FK81BD:

I've manually updated the page each few minutes and hoped for a
decode and
now here it is :-)
Hope i can do it a few times more this night :-)
This is the path:
