Oscar-10 Beacons and Transponders
---------------------------------
Beacons
-------
Mode B General Beacon - 145.810 Mhz.
Mode B Engineering Beacon - 145.987 Mhz.
Mode L General Beacon - 436.04 Mhz.
Mode L Engineering Beacon - 436.02 Mhz.

Telemetry
---------
Formats Available: Any digital code (Morse code, radio-teletype, ASCII, etc.)
can be employed since the format is controlled by software residing in the
spacecraft computer which can be altered via the command links.
General: Plans are to have the general beacons carry morse code to provide
updated messages and selected telemetry channels. Engineering beacons
will ude 400 baud PSK/PCM. Decoding the Engineering beacon will require
a microcomputer and an AFDEM (Audio Frequency DEModulator) that is
connected between the ground station receiver audio output and the computer.
