Any fool  can repeat  what  others  say  , but a lesser one  might  repeat the  whole  text  
 
So  , as  I posted ,
 
''Problem is  you  cannot  up the  time  to  down the  s/n as  you can  on 136
 
I have seen  MW  UK/VK  dx using  carrier  detection  just  behind the  gray  line , that  would  need  a  100%  carrier running  for  may  be  2  hours  round  that  time  , but the  window is  not too  big , may be  , 15/ 30 mins ?  
no chance  for  any qrss/data   , just a trace in the  sand  ? ''
 
 
 
Problem is  you  cannot  up the  time  to  down the  s/n as  you can  on 136 , >>> True ?
Its possible to   observe  signals   from  VK on MF   >>.. Ture ?
time  window  small   >> ture ?
Special  set up long carrier   (rx)  ? >>  ture  ?
Observed signal  very low out side  data >>  true ?
 
so  what  particular point  is  worth    repeating concern ?

Hi Stefan,

 

in 1923 wrote Paul Godley (call 2ZE): The amateur is a fool: ignoring that something is impossible, he makes it happen.

 

Maybe little has changed since then ;-)

BTW i want to remember what was written here last tuesday:

G..

Your results demonstrate once again that it is always worth to try what seems to be impossible! :-)


Am 17.02.2013 13:08, schrieb André Guyé:
What about the use of long period of TXing, as WSPR15 or QRSS ? For this very long path, I think that the opening duration time is too short for that use ?

Well first it would be interesting to get some informatiuons about Dale's TX system. And if normal WSPR-2 decoded, then QRSS-10 should be possible as well
WSPR-15 may take to long, the opening times are quite short, as you say. But anyway, this opens a new field for experiments. Of course it is worth to transmit during the time that path is open! And it is good that the WSPR "dial" frequency in VK is different to ours, so we already have splitted bands for RXing and TXing here in EU and VK.

 

Now, as Dale said to me in a mail, one spot is not sufficient to valid that.

Why not? If you say that you didn't use a WEBSDR or other tricks, and got a decode. Where should the information in the WSPR window come from, if not trough the RF radiated in VK?



Again, my best congratulations to this impressing result!!
