Anatoly Zak reports on the maneuvers of Cosmos-2504 whose signals were
detected by a Dutch amateur radio enthusiast Cees Bassa.

Cosmos-2504 was launched on March 31, 2015, at 16:47:56 Moscow Time from
Site 133 in Plesetsk. Just hours later it was noted it was transmitting
signals similar to previous maneuverable satellites Cosmos-2491 (RS-46)
and Cosmos-2499 (RS-47).

The request to power up the Ham Video system was added to the crew task
list on April 16.

That means, that crew is invited to activate Ham Video as a free time
activity. No precise day/time for this activity is fixed.

Please monitor the 2395 MHz at 2.0 Ms/s frequency and tell everyone as soon
as you observe it.

This will be a period of blank transmission for testing and calibration.
Please make maximum use of it.
