*AO-51
update

Hello All,

According to projections, the next 100%
illumination period for AO-51 has begun. Hopefully for the next week or two
we can run both transmitters ON at reasonable power. The PL tone isn’t
needed (and hasn’t been for the last few weeks).

FM Digital PBBS,
U
Uplink: N/A
Downlink: 435.150 Mhz FM

FM Repeater, V/U
Uplink:
145.920 Mhz FM
Downlink: 435.300 Mhz FM

Even though AO-51 “sees
sunlight” all the time, it doesn’t “see” the sun equally throughout an
orbit. So, we are going to keep the power management software running in
hopes that we can optimize the transmitter power output and keep the battery
temperatures down.

The way it is currently configured, AO-51 can run in
one of three states, depending on available battery power:
1) HIGH
435.300 at 550 mW and 435.150 at 420 mW
2) MEDIUM 435.300 at 420 mW and
435.150 at 300 mW
3) LOW which currently sets both transmitters effectively
to OFF

Activity reports over the next few weeks to http://oscar.dcarr.org/ (or to me at n8mh
AT amsat.org if Ao-51 appears to be OFF) will be very much
appreciated.

And finally–telemetry files (KISS format preferred)
from around the world will be greatly appreciated for the next few
weeks!
