Hi Michel, Markus, MF,
Michel, nice to meet you here via email. Thanks for your efforts to
listen on 630m. My congrats to your/our success. RXwise and TXwise,
your location is the best antenna! There is no amateur radio band in
which a location close to the sea is so important than 630m i think.
Anyway i did not expect that this path is possible regularly for radio
amateurs. Many years we saw now that good results can be obtained
arround Europe. But it becomes very hard to cross 2000km on a land path
(seen by detections from Russian stations beeing close to Moscow).
Transatlantic detections between EU and NA are highly affected by
geomagnetic activity. But the TA path is possible in winter and in June
(along the greyline). This is what i learned and observed since 2012 on
that band.
Then there have been very rare events (constructive QSB) where
detections above 8000km have been made, maybe 1 in 2 years, the most
popular is VK1DSH -> F6CNI/BOG.
Obviously it is just to a lack of stations in certain locations why my
impression of what is possible on that band is so limited (ok, there
are NDBs but that's not my world). So now it's good that we both and
others can try that path!
The best is: We managed a 2nd decode this night!

So it is not soooooo rare, it rather looks like the path is possible
regularly ??
At least it is worth to try regularly now to learn more about the
availability of that path!!!
It is worth for you to build a directional antenna and worth for me/us
to stay up arround 0...1 UTC and run a higher power and transmit
intervals to see what is possible. I was TXing each 10 minutes (20%).
Maybe i'll try with 50% this night arround that time if you are QRV.
If THIS is possible, now even with -26 dB SNR, what else could be
possible on this planet and frequency? :-) A south path (not to close
to the polar region(s)) seems to promise many surprises...
Let's see what's possible tonite...
What are your plans to improve the performance of your station? Do you
have any? I can recommend to try a simple resonated toop as an
alternative antenna. I have very good results with loops. And the null
of the loop will point to Africa, which is most probably an advantage...

PS: Maybe you want to join the LF reflector to announce your
experiments and discuss about various RX antennas and experiences?
Informations on how to subscribe can be found on my qrz.com page and
maybe somewhere else. There are several French stations here as well :-)

HI MARKUS I am realy FR5ZX.
Thanks you very much for all informations Last night, I spot
again DK7FC on 630 m with miniwhip and RX winradio G313E. but one
time only for all the night.
Last week I heard SAQ on 17.2KHz above noise with the same
equipment.
I will active on 630M with TS590S + 100w home made AMP (Not
enough power I think) But the real problem is to put an
effective antenna in the garden.
I am often listening low bands and had some hope to test with
South Africa, but nobody. I never heard Australia.
The first station I receive here is DK7FC THANKS TO HIM
Neverless MARKUS and be sure I am really
FR5ZX ex F6AAO at Valbonne on the french RIVIERA.
73'S for all
Regards MICHEL FR5ZX
