[amsat-bb:66293] AO-40 Update, 2003-02-21

S-band Receiver Test
---------------------
The AO-40 team plans to test the S1 and S2 receivers with the K-band 
downlink on Sunday, February 23rd from MA 162 to 170 ( UTC ~19:26 to ~20:01 
).  This will necessitate switching OFF the S2 Tx during this time.  As is 
currently scheduled each orbit, the S2 Tx will be on, beacon only, along 
with the K-Tx during the 160 to 162 window.  However, from 162 to 170, the 
S2 Tx will be off and only the S1 and S2 receivers, plus beacon, will be 
connected to the K-Tx.  Stations with K-band reception are invited to 
monitor the tests.  Normal passband operation should resume after MA 
170.  If weather or technical problems are prohibitive, we will 
reschedule.   Because this is a single event test, the N-blk will not be 
modified to reflect this test.
