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:

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