I paid attention to FSS telemetry Counter and calculated
the spin rate of the satellite.

 60 / (173 - 156) = 3.53 rpm
 60 / (189 - 173) = 3.75 rpm

I calculated where of the FSS data which I received and
generally became from 3.5 to 4.0 rpm. I compared it several
months ago, and it was numerical value of half. It was a
little less than 4 rounds per one minute, so one round turns
considerably slowly in 15 - 17 seconds.
