AO-40 Schedule Change




There have been multiple requests to try the V uplink and the operations 
team would also like to determine what the V-Rx hears in the way of 
hemispheric "interference" on 145 MHz.  Therefore, as an initial test, 
from  MA = 120 to 128  on Wednesdays only, the V-Rx will be connected to 
the S2 Tx, along with both L-band receivers.   Operators with ~145 MHz IF's 
from their downconverters will experience extreme desense when trying to 
uplink on 145 MHz,  but those with 435 MHz  or other IF's should be able to 
hear themselves on the downlink.  The uplink passband should be 
approximately 145.840 - 145.990. Please post observations to the amsat-bb.

The K-Tx segment has been temporarily discontinued.  We were experiencing 
some fluctuations in power output believed related to the very cold 
temperatures.  Temperatures will begin to warm as the solar angle moves to 
the Z+ end of the satellite, and the K-Tx sessions will resume in a few weeks.
