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!

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... 73, Stefan/DK7FC PS: Maybe you want to join the LF reflector to announce your experiments and discuss about various RX antennas and experiences?

         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
