[amsat-bb] revision 1 - AO-51 schedule for September through early October 2010

[Mark L. Hammond]

Hello All,

Shortly after posting this I realized I got something wrong--given the
times of passes, mode changes are going to occur late in a given day
(usually 2100-2330 UTC range), using UTC dates/times (not the very
early hours of the next UTC day).  So I have revised the schedule
information below to reflect this.  Schedule changes should happen
Sunday evenings, Eastern Time (that hasn't changed).

Another note--when the L-band uplink is active, most users report a
better experience using a frequency tuned a few kHz "higher" than the
published frequency of 1268.700 MHz.  Try something in the 1268.703 to
1268.708 MHz range...and experiement for best uplink!
________________________________
Revision 1--9/9/2010

Here is the AO-51 schedule for Sept. and early October.  Thank you for
your requests.

We'll continue the mode starting October 4 through the AMSAT Symposium
and beyond.  We'll post more information after we see how the bird
performs during the coming weeks.

Notes:

1) As always, the schedule for the 435.150 transmitter is subject to
change so that command stations can download telemetry files for
analysis.
2) "late UTC" and the mode change dates below translate into schedule
changes occurring over the eastern coast of the US on Sunday evenings.
3) the schedule is subject to change based on the real power budget we
experience.
