AO-40 telemetry Orbit 87



Hello,

I observed today (January 9th) morning S2 MB from AO-40 between MA 16
and MA 20.
I´ve received 35 A-Blocks, all with CRC ok.

VHF transmitter temperature and power shows following:

19,3                       75
19,3                       73
18,6                       61
18,6                       60

The VHF TX was switched off.
I think, the VHF TX was on a few MA´s before MA 16, that´s
possible the reason for the falling temperature from the TX.
But why is the power display falling so slowly?
Any idea?

73´s
