IFC Battery Control

Also see Part of the digital modernization (about 1980)

This is where the Battery Commander (or Battery Control Officer) and the Acquisition Operator sat. This was the central command place of the battery. Summations of the status of other places of the battery arrived here, and commands to battery components went out from here.

Visitors could view this area, but only after various charts and documents were covered, such as:

- A pie diagram showing the azmuths and elevations below which our radars could not see.
Near by big buildings, trees, etc. had a large effect on this
- Various other commands, codes, and materials regarded as classified.
- The main plotting boards often contained diagrams of safe zones, ... visible under the thin transluctent plotting paper.

John Porter, manager of SF-88, reports that
"The Battery Control Van is 20.5 ft long, 8 ft wide, 7 ft high, with a 6.5 ft tongue."

From Ted Willes
I was looking at the picture of the Battery Control Van. Didn't the computer operator sit just to the right of the BCO? I recall that he was there to relay azimuth data to the LCT for emergency procedures purposes. The s/w operator was to his right. (Or is my memory even worse than I thought?) As I recall, the BCO was on the MM circut, the ACQ operator on the Command loop, and the computer operator on the tech loop. The BCO had a switch that allowed him to talk on any loop.

Now for a little embarrassment - I forgot where I got these images, or who to give credit to -

a clue might be ImageDeposit_dot_com_FREE_Hosting_BIG_UserID_1596_Image_number_2DEEBA8F2B.jpg
This is an upgrade modification from the Hercules equipment at SF-88.

More embarrasment - maybe confession is good for the soul, my soul.
I figured I was a hot shot on almost everything in the IFC - EXCEPT -

So guess what shows up in the e-mail from Michael Keller - mike _ os @ web . de

More Plan Position Indicator (PPI) ("radar scope"),
This is not a "study" of the PPI, just some more images taken during removal of fan noise from a failed bearing.
