[amsat-bb] COSMOS2499 (RS-47?)

[Jean-Pierre Godet]

   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 !
