IDEFIX on 145 MHz



For a few orbits now, the 145 MHz TLM data are all set to zero.
This means that something is going wrong on the analog/digital conversion
part of the system.
We suspect the - 23°C / + 35°C temperature cycles to be a possible reason of
the defect.
The temperature should decrease again now, so watch the 145 MHz TLM data to
see if it works OK again.
The CPU is OK, the voice storage device also.
The 435 MHz payload is OK.
Yesterday night, we had a very clear sky and IDEFIX passed just over Paris
(Elevation 90°!)at midnight.
Several people in France (including Paris downtown, with its intense lights)
were able to hear and to see IDEFIX/ARIANE 42P at the same time.
