[amsat-bb:64805] AO-40 Update, 2003-01-01

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

The AO-40 schedule has been modified to activate the 24 GHz K-band 
transmitter.  From MA 126 to 128 both the S2 and K middle beacons only will 
be active.  From MA 128 to 132 both the S2 & K transmitters will be active 
on the U/L uplink passbands.  The last time the K-Tx was active, it was 
noted to have suffered a partial power loss suggesting that one of the 
output transistors may have failed.  We will monitor its function to see if 
this condition has changed.  Please report your successes/failures to the 
amsat-bb.  We are holding ALON/ALAT at nominal 0/0, but ALAT has been 
drifting slightly positive (~1 deg), which will slightly favor northern 
hemisphere users.
