Thank you for the information, Pete,
I noticed that the COSMOS-2499 (and the COSMOS-2491), like was the
Yubileiny-2, are transmitting ONLY when in sight of the Russian
Federation.
In western Europe, we have a pass East begining in about 45 mn and the
two frequencies will be on. Nothing will be heard on the next one over
North Antlantic.
Best 73 !

Many thanks, Jan,
I was afraid that this was a coincidence, another bird in the vicinity.

Hi Jean Pierre,
I did receive RS-47 CW Look at
http://www.dk3wn.info/p/?p=52752
But this was the only time, after that I didn't receive any CW
from RS-47.

Hi my friends !
I'm listening the passes over western Europe of the COSMOS-2499,
but there is no CW telemetry nor callsign, never, only the usual
russian DOKA-B telemetry on 435.465 and 435.565 MHz . Perhaps an error
?
Then, again this morning, I watched carefully the R4UAB blog video,
especially the frequency vs time, then I "replayed" the november 30th
day as seen from Dmitry/R4UAB location (Ruzaevka, Republic of
Mordovia, Russian Federation) with the keplerian of COSMOS-2499, the
fresh good ones of NORAD :
The Doppler frequency shift crossed 435.465 at about 23:15:48 on
the video. At the moment, the bird was not over Russia but near the
East coast of Australy. I thought, maybe the clock is not UTC but
adjusted with the time zone of Mordovia (time is MSK (Moscow), UTC +
3)... So I tried 19:15:48 UTC but, yet, the bird was then not over
Russia but the Pacific Ocean.
Any ideas ? The tle are the correct ones, sure, and you may verify
yourself. I'm using them without problem and all the visible passes of
the 2499 are received just in time, exactly, since saturday november
30th.
Have a nice week-end, 73 !
