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 tomonitor the tests. Normal passband operation should resume after MA 170.
If weather or technicalproblems are prohibitive, we will
reschedule. Because this is a single event test, the N-blk will not be modified to reflect this test.
