[amsat-bb] AO-40 Update, 2003-03-09

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

AO-40 nominal ALON/ALAT is now 20 / 0.

Because of the poor squint angles early in the orbit the passband window 
now starts at MA =80.
It still ends at MA = 230 to allow time for battery charging before perigee 
eclipse.

CORRECTION:
Several weeks ago, during the testing of the S1 receiver, I indicated that 
the S2 receiver was connected to the 5-turn helix.  This is not 
correct.  Both S-band receivers are connected to the dish antenna.  Only 
the S2 transmitter is connected to the 5-turn helix.  Sorry for the mix-up.
