RS-13 telemetry



RS-13 (Radio Sputnik)
Linear Transponder RS-13 Non-Inverting (CW/SSB):

  Mode KT Uplink     :  21.260 -  21.300 MHz
  Mode A Uplink      : 145.960 - 146.000 MHz
  Mode KA Downlink   :  29.460 -  29.500 MHz
  Mode T Downlink    : 145.960 - 146.000 MHz
  Robot Uplink       :  21.139 , 145.840 MHz
  Robot Downlink     :  29.458 ,  29.504 MHz
  Beacon frequencies : 145.862 , 145.908 MHz


I received RS-13 CW telemetry at 23:08:20z Feb 21, 2002,
with 145.862MHz, 1200bps.

  RS13 IIW81 INU08 IAW00 IMW45
       NIS45 NNR00 NAR00 NMW00
       AIR24 ANR30 AAR32 AMR30
       MIW47 MNW45 MAR00 MMR00 RS13


And I analyzed each channels as follows.

  1. Telemetry sampling period, 10 min.  ; power supply  81/4  = 20.3 V
  2. 2 mtr RX , 0 dB attenuator ON;  power output 2m TX  08/10 =  0.8 W
  3. 15 mtr RX, 0 dB attenuator ON; power output 10m TX  00/10 =  0.0 W
  4. 15 mtr uplink, ON            ;          15m RX-AGC  45/5  =  9.0 V
  5. 2 mtr RX, OFF                ;           2m RX-AGC  45/5  =  9.0 V
  6. special command station channel, OFF ; command AGC  00/5  =  0.0 V
  7. output power 10 mtr beacon no. 1, MAXIMUM; parame.  00/3  =  0
  8. output power 10 mtr beacon no. 2, MINIMUM; parame.  00/3  =  0
  9. status of first memory board, OFF        ;  10m TX  24-10 = 14.0 C
 10. status of second memory board, OFF       ;   2m TX  30-10 = 20.0 C
 11. there is infos in memory no. 1 ; 20 V power supply  32-10 = 22.0 C
 12. there is infos in memory no. 2 ;  9 V power supply  30-10 = 20.0 C
 13. memory data send via beacon 1  ;  9 V power supply  47/5  =  9.4 V
 14. 15 mtr robot RX attenuator, 0dB ; 15m robot RX AGC  45/5  =  9.0 V
 15. 2 mtr robot RX attenuator,-10dB ;  2m robot RX AGC  00/5  =  0.0 V
 16. output power special cmd channel, MAXIMUM; less than 32QSOs in log
