Two faulty/missing fans in the 6-fan rack between Rx 1 and Rx2 were replaced
so that all 6 now work. (J.-B.H.)
PC clock still OK, to within ca. 1 sec.
09:20 UT, power-line glitch (lights blinked) and HV off. HV fuse still OK, restarted.
Did notice that the fwd and rev power meters no longer show anything.
Checked +24V and +5V supplies at rear- OK.
Noticed PC clock 4min 19sec slow ! at 09:32:41 UT.
Corrected at 09:42 UT.
Various tests of spare SKY boards in our PC- OK, they work.
Spare ADC does not work in our PC.
After having HV and Fils off during ADC/SKY tests, I tried to switch them on again.
Got Iav 200-300 mA and relay clicking. HV fuse still OK (0.7 Ohm).
Switched off and run on A300 only while
I leave for Svalbard. (MTR).
ca. 08:00 UT Moved PRE/digisonde interference out of our rec window.
(CH was at PRE yesterday- maybe something there was reset).
