Of course Roman , can have funny wrong call's any data
mode will make those , more funny is people compare
data decoding with correlation detection and not realise
why correlation has lower s/n , and particularly
hilarious is those who know what's happening and don't
tell anyone .
Opera only deploys dynamic on 477/136 , the HF to SHF
are all simply data decodes, where as the Magic Mode has
mixed correlation and decoding on all bands , which
explains how it survives Doppler spreads 3 times its b/w
on 10 MHZ and even works , some times on vhf .. mfsk can be
correlated , just the same as ook , the time locking
has more to do with pattern matching, than decoding data .
As some one pointed out , 'What ever colour the cat , as
long as it catches the mouse' just in this case , the
cat's out of the bag and it turns out , there are more
than one in there .
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 ! ;-)

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