Stacey Mills, W4SM, provided the following update regarding AO-40's
telemetry beacon. Stacey says, "FEC is turned on as for as many orbits as
possible, working around the need for pictures and other command functions.
FEC mode requires loading the IHU-2 each orbit and this is not always
possible; however most orbits have FEC active. The FEC routine has been
modified to allow the option of cycling between normal mode telemetry
including message blocks and event blocks, and FEC mode telemetry (A-blocks
only). With this option, the normal mode is currently active from 0 to 16
minutes of the hour, and the FEC mode is active for the remainder of the
hour. This allows time for users to read the message blocks and for event
blocks to be collected. During transition between these two modes, up to 1
minute of beacon "idling" (hex50) may be heard before the new mode starts."
The AO-40 team would like your telemetry files!
Please "zip" compress your daily telemetry files and e-mail to:
ao40-archive@amsat.org
[ANS thanks Stacey, W4SM, for the above information]
