LO-19 status Sep 19



I received LO-19 CW telemetry on Sep 19, 2000, with 437.125MHz.
The followings are some nominal data on 01:30 UTC, Sep 19.
One frame contains eight numbers data of three figures as below.

First line is the actual received data and second line is the 
replaced data with real number by the next transformation. And
I analyzed these data by the equations in [SpaceNews 27-Dec-99].

For the above data :  5 LUSAT HI HI 60 129 179 139 178 133 160 154 156

  The number of Eprom program version : 6, and RAM is OK.

  CH 1 : +5 voltage                     636/129 =  4.9    V
  CH 2 : +10 battery voltage          0.064*179 = 11.5    V
  CH 3 : CW transmitter temp  0.354*(134.7-139) = -1.5    C
  CH 4 : TX Output power      (10.9+178)^2/40.1 =890.0   mW
  CH 5 : Box#4 temperature      0.356*(133-129) =  1.4    C
  CH 6 : +10v current                   0.7*160 =112.0   mA
  CH 7 : +Z panel voltage              0.15*154 = 23.1    V
  CH 8 : +8.5 voltage                 0.056*156 =  8.7    V
