Dear friends,

Thanks to Jean-Louis Rault F6AGR who quickly informed me, I heard my

first signal from Yubileiny-2 RS-40 on monday July 30th afternoon. The signal of the 435.365 MHz beacon was fairly strong regarding my poor receiving devices and aerials. After that, the beacon was heard on 435.265, but more often on 435.365 MHz, sometime none of these two frequencies. I am using the 2012-041D NORAD elements. I am not sure it is the good one, but for the moment A, B, and C, the three others payloads launched with the same Rockot vehicle are not too far away.

Trying to get information about the Yubileiny-2 satellite, I sent

inquiries about the telemetry and the possibility that may be one of the beacons will move to CW as it was done with the previous Yubileiny-1 RS-30 and Mozhayets-4 RS-22, but I received no reply till now : three mails in russian, to the Siberian State Aerospace University (RS-40 instruments and research mission, Rrasnoyarsk), to ISS Reshetnev (company manufacturing the RS-40 satellite, Krasnoyarsk), and to A. P. Papkov (Laboratory of Astronotical technology, Kaluga, who published the telemetry decoding of RS-22 and RS-30). We are waiting with hope but, may be I am wrong, looks like the university and the ISS company are not very interested by a collaboration with the radioamateur community, only by their frequencies around 435 MHz.

73 !

Hello Jean-Pierre

You are right, they have absolute no interest for us radio amateurs. And this could be a problem, if this Russian satellites flies over Europe and transmits their DOKA-B signals in FM (!) in the 435 MHz frequency range.

Look for first hand infos in this PDF-document: http://home.datacomm.ch/th.frey/Yubileiny-2.pdf

MiR(Yubileiny-2) is active in DOKA-B only in range of a control station in Russia, e.g. Moscow.
