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 !
