Background

Insight Aviation Strike Finder 1976 very first storm detector.
YouTube: Stormscope teardown and power on - 1991 data code on ICs,

The first generation WX-7 StormScope was invented by Dr. Ryan.  3M bought the Ryan line of StormScopes.  B.F. Goodrich bought out 3M.  The current owner of them is L3 Communications.

Description

WX-110 StormScope Ground Lightening System

On the front panel it's called the WX-110, but the label on the rear panel says WX-110/220 Ground System.  What's the difference?  Let me know.

Not sure if this is a problem caused by no antenna or

No beeps were heard at power up.

may have oxidized, as described in What Goes Wrong.
Now to figure out how to disassemble it.

NY-163 Antenna

There seem to be at least two StormScope antennas.  The early one with a 10-pin connector is refereed to as the NY-163.  The later one has many more pins.

Note the voltage to the NY-163 should be within 5% of 12 Volts, so there's a problem with the WX-110 box in that it seems to be able to supply either 19 or 5 volts?  May not be the case.  Need to fully check out the voltages on the DB-25 connector.

WX-110 Indoor Console

The front panel mounts that display which has four buttons.
The rear panel has an AC line cord, On/Off switch and DB-25m connector.
Inside there's an AC to 19 VDC power supply that can be set for 110 or 220 VAC input, this one is set for 110 VAC and has an American line cord.
There is also a stack of three printed circuit boards that are about 3" x 7" and the stack is less than 2" tall, i.e. they would all fit behind the display.  Their function is both the "processor" and the display electronics.
