Exactly so Stefan
 
Qrsss   would  of only  been a  trace  in the  sand (of  Mr Wolfs very  good  SL)
 
No chance to  send  qrssss  or  use data to  write   'I have 2 cats' 
 
But a beacon has decoded  in 120  seconds  , don't  forget  , not  all  of   wspr  needs  to  be  decoded  to  get a  result , you  only  need 1  sync point .  [ q is  wspr  still  using the  2  frame's  or  single  ? ] 
 
It was  all  over  in a  'flash' : )
 
Even  allowing  for  the  possibility of  a  false  decode , with the  time correlation  , I would  say , that is  a confirmed  decode , at  double the  range  of  Gu's sm6bhz,   China  decode  some time  back , which I think was  also  a  'single'  decode  , at the  time  he  was  running  100%  tx  cycle ,
 
160 in the  last 2  weeks shows 2 spots

Outstanding   results    Dale  and Andy
 
Hard  act to  follow  !

Andy, Dale, MF,

First i want to express my congratulations to this most impressing achievement! It is certainly VERY encouraging for the other WSPR transmitting stations to try what seems to be impossible.

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! :-)

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!!
