- 60: PAM3/3 Tue 25-Jul-1995 21:49:22 GMT Lightning hit on 7/22/95 knocked out the station
Station 3 took a nice lightning hit on 7/22. Visitations on 7/23 required the
electronics box to be returned to the base for work. The VME power supply
took a hit on the +5V standby power. This bit of circuitry was not protected
by tranzorbs or a fuse. Locating the problem with the station was exacerbated
because the fuse on the power supply did not blow. After burning out three
fuses on the battery, enough smoke was generated on the power supply to "see
the problem".
On Monday 7/24, after reinstalling the electonics box, found the Freewave, the
GOES transmitter, the bandpass hygrometer, the RS232 to 485 converter, and the
data logger were out. The data logger problem turned out to be simply the
SC32A opto-isolator. Returned both radios to their manufacturers for repair
or burial as requiered. The Freewave was hit on an 8V regulator and some
associated analog circuitry. The GOES radio was hit in its self sacrificing
tranzorbs and associated circuitry.
The front panel connector on station 3 is the the one with the bad power input
trace. The bypassed trace may have weakened the lightning protection for the
power input to the station. Redesign of the front panel power section is in
order.
The station is currently limping along with local data storage only. The prop
vane, the Trh sensor and the barometer are OK. The ATI sonic is giving spikes
on the V component at the very least.

Was put back on the station after being taken off on

repaired.
GOES Xmtr:
Was put back on the station after being repaired by
Signal Engineering. It had been taken out by the
lightning strike on 7/22 and sent to SE on the 25th;
good turn-around.

A number of jobs were done at PAM 3 yesterday. These included
installation of the bandpass hygro, leveling the tower, and putting
one of the batteries on a charger located in the ISS trailer. We still
need to add new desccant to the net rad sensor and download the new
configuration that has the new BPH coefficients.

Net Radiation:
Leveled sensor using the electronic device to within 1 degree or
better. The sensor was probably within 2 degrees before.
Power:
Put 3rd battery back on the station after charging it on AC in
the ISS van. It was still pulling quite a bit of juice even
at that.
BandPass-Hygrothermometer / EVE:
Downloaded a New Configuration that has the correct coefficients
for the bphygrometer. Was Coef for sn25, Now is Coef for sn27.
Data looks OK.
- 91: PAM3/3 Sun 06-Aug-1995 15:44:53 GMT Visit station 3
I took a trip out to station 3 to do intercomparisons. The
station is ok however we do have some problems with the code
on the compaq. Whenever you leave an intercomparison check the system
refuses to reload the station script. I had to 'alt x' to get out.
The log files about the visit were saved. Below are the results
of the intercomparison.

- 97: PAM3/3 Tue 08-Aug-1995 13:14:58 GMT Visit to station 3 yesterday
Went to station 3 to backup local data and work on the
rain gauges. The switch in the MRI gauge was bad. We will replace
it with the MRI from station 2. There was not response out of the
ETI gauge. We will have to hookup the compaq to the processor and
see what happens.
One final tidbit, I saw a snake out there near the station.
