               TELEMETRY OF "RADIO-M1"
               -----------------------

Radio-M1 transmits Morse code (CW) and digital telemetry.

CW telemetry will start as soon as the bird separates from
the launch vehicle and Radio-M1 equipment will be powered by
main satellite power system.

CW Morse-Code telemetry frame consists of the registration
call RS14 and  8 four-digit lines in the following format:

     RS14  1A 1B 1C 1D
           2A 2B 2C 2D
           3A 3B 3C 3D
           4A 4B 4C 4D
           5A 5B 5C 5D
           6A 6B 6C 6D
           7A 7B 7C 7D
           8A 8B 8C 8D

The 1A to 7A lines are analog telemetry data. Line 8A is
calibration engineering parameter.

The first digits from 1A to 8A are system status data:
figure 6 means general operating status
figure 2 means command operating status.

The second digits from 1B to 8B (0 to 7) are numbers of
line (channel).

The third and fourth digits from 1C to 8D are analog
telemetry datas.
