Hi David, Markus, LF,
Thanks for the information about Bob's capture.
I forward this capture to the group, if we (Bob and me) want to have a
official confirmation that these traces are accepted as a valid
detection. We have to check if the transmit times are matching.
Of course a bit clearer detection would be wishful but we are on the
limit of what is possible with a non-commercial setup, far away from
QSO mode and full call reception. Most odd for HF amateurs, probably
;-) Anyway an amateur generated signal that changed the brightness of a
few pixels in a spectrogram on the right frequency and time :-)
VK7ZL to DK7FC is a path of 16784 km,
http://no.nonsense.ee/qthmap/?qth=QE37MF&from=jn49ik00wd,
unbelivable.
I hope there are some days left to see further traces
which confirms things.
Now i hope for Markus' detective help ;-)
My grabber archive captures from yesterday, 20. March 2012, shows a C
at 17:00 UTC, here discribed as a K in Bob's spectrogram. Actually i
think there seem to be some bright pixels where one expects them if it
would be a C. http://dl.dropbox.com/u/19882028/LF/EU60_53273.jpg
At ~19:25 UTC (the 7) i was actually transmitting a 7, see
http://dl.dropbox.com/u/19882028/LF/EU60_53318.jpg
For me that is convincing and so i would like to congratulate Bob/VK7ZL.
Comments welcome.
73, Stefan/DK7FC

Hi Stefan,
Looks like Bob (QE37mf) had success last night. Nil from here.
Regards,
David.

Hi David
I think I may have copied part of DK7FC

snipped.

(size to large for the reflector)
Or perhaps it is just wishful thinking.
PS I notice your grabber clock is incorrect.
Bob
