[amsat-bb:65528] AO-40 Update, 2003-01-26

["Stacey E. Mills" <w4sm@xxxxxxxxxx>]

At MA 2, Orbit 1028, AO-40's middle beacon came on only very weakly until 
MA 55 when the S2 Tx was manually cycled off/on by a command station and 
came back on at full power.  This has happened several times in the past 
and appears to be due to the S2 ALC.   In this particular case, it may be 
related to the fact that the beacon was cycled back on only shortly after 
eclipse when the batteries were still relatively low and the temperature 
was still cold.  We have modified the schedule to not turn the beacon back 
on until MA=10.
