Graham I rx too mny false and fantoms in OPERA for long 3 years.

As usual this is not real calls.

That's  interesting  Luis ..one  those  . the  kings  not  wearing  anything   moment's  jiji

 

By the  qrg 400k  , this  was a  wspr  2  TX ?

 

So the  only  way  Stefan's  call  sign  could be  recovered   is from the  look  up  table as  part of a  correlation  process [ see other  linking posts]

 

Its  IMPOSSIBLE   for  Opera  to  produce  such false  Decode 

 

But if you  mean  DYNAMIC Detection  , has  Ghosts ,  that's  true for  any  correlation  system   and the  ghosts always  take on real life  forms 

 

However the  Phantom , has  provided  a  Time  stamp   Ghost  Buster  validation  system  . something  wspr cannot as it  already uses the  web  for  time  locking , oddly , accurate  time is required for  a  correlation  system ...

 

People  are  not  too  sure  of the  difference  between  Decode  and Detection  ,    but those  who do , like the  extra  dB's one  gives  over the  other 

 

As I  noted  previously 

 

''no  one minds a  bit of the   'Old Jaspers'  as  long as its not take too  seriously''

 

6 meters  is  known as the  Magic  band ,  may be  wspr  should be   the  'Magic'   Mode

Hi Mike, MF

 

From my records last night, DK7FC was transmiting in 06-16-26-36 ... periods, but not at 23:04

The locator shown in your decode is also wrong

 

The closest frame to the time you decoded was at 23:06

2306 -21 -1.2 0.475684 0 DK7FC JN49 30

 

Not only Opera has its ghost ! ;-)

 

PS: I'm QRV again. Back from a 15 days vacation trip

Hi All: I'm not sure what to think of this....

 

https://www.dropbox.com/s/xwnopmbl2fz5ye5/IMG_4537.JPG?dl=0

 

I have been experimenting with IF shifting my radio to get WG2XJM very strong signal 10 to 13 dB down the IF bandpass

 

curve to improve weak signal reception of other stations when Eric is transmitting.  Odd sunset partial captures appear

 

to be transatlantic, but I am not sure about reality with this data. My EWE antenna was configured to favor a SE direction, but with

 

120 degree 3dB beam width pattern it covers the NE as well.   Long distance transition zone propagation is a possibility, but I

 

would be hesitant to claim it not having received correct grid square information......
