How to take a NATO Radar station off the air, without really trying.

 



Back in 1962, as a newly trained electronics technician, I was posted to a Radar station in the Norwegian arctic to look after radar transmitters and receivers and signal processing equipment.

The station was part of a chain of similar installations providing radar coverage of the boundaries of the Soviet Empire of the day, from well north of Norway to Turkey in the south.

The idea was to be able to intercept Soviet aircraft intruding into NATO air space and monitor all air traffic as well.


For science fiction buffs, the station would have been a marvel to behold: A zig zagging road, going up the side of a steep mountain and disappearing into a hole in the mountain side part of the way up.

Going into the tunnel, a huge cavity opened up, containing a large concrete building.

Inside that building things got even weirder: Several levels and one large room like a cinema with a big screen in front and multiple radar screens with rotating beams and an operator at each one.

A crew of plotters worked behind the big screen, manually moving images of aircraft being tracked across the screen.

Almost one thousand meters above this bunker, on top of the mountain, were multiple radar transmitters and receivers, with huge rotating antennas emitting radar impulses of some 5 million watts each, reaching into space for the bodies of any aircraft, and being reflected back, to end up as an echo on the radar screens.

And, between the bunker inside the mountain and the top of the mountain was a railway tunnel, ascending at an angle of about 45 degrees for 1,5 kilometers with a rail car pulled by a cable.


The station was operating 24/7/365 with several shift crews alternating. It was a big operation with a military camp in the valley below the mountain housing all operational personnel.

As a rookie technician, one of my early duties was to change out an oscilloscope mounted in one of the signal processing racks in the bunker. It was plugged into a power socket, behind the scope, inside the rack.

So I had to feel my way, while stabilizing the replacement scope in one hand and the power plug in the other, to plug it in.


That when shit happened: I found myself having suddenly moved two feet across the aisle between signal processing racks with a rather blurry view of reality.


As I came to my senses, reports came in that the whole radar station had gone off the air all of a sudden.


It didn’t take too long to figure out what had happened: I had blown the breaker in the instrument rack containing the oscilloscope, which rack contained the master oscillators for all the equipment in the station.


For want of timing pulses, the transmitters on top of the mountain powered down automatically and the place just went dead.

This was immediately reported to NATO headquarters in Paris, France, so as prevent them from assuming that an air attack had happened during those volatile days of the cold war.

As for me? Nothing was ever said about the incident. They probably figured that I had learnt my lesson.

I have a hunch

Russian progress in the invasion of Ukraine is not going to plan. That is evident from negotiations between the warring parties as I write this piece. I have seen photos of burned out military vehicles and speculate that they are Russian. Back during the end days of WWII when Soviet armour invaded Germany from the east, Germans were issued with large numbers of shoulder mounted anti tank weapons to help slow down the onslaught: Strategically positioned, one man could take out a Soviet tank in short order. And that happened. Fast forward to Ukraine, shoulder mounted missile launchers are an order of magnitude more effective than in WWII with smart missiles actively seeking their targets over the course of their trajectory. Sitting inside a tank these days, is sort of like being a knight in shiny armour, in the face of a lead ball from a musket. The tank becomes your coffin.

Metaphysical speculation

. George Orwell (Eric Blair), the famous author of "Animal Farm" and "1984", among other works, used to work in the British Imperial Civil Service during his early years, as a policeman in Burma, as I recall. A statement he made in reflecting upon that time in his life, when a local person was executed for something he had done, has stuck with me: "A universe ceased to exist" Over the years, that statement has given me pause for reflection on many a time, especially following a car accident in 2011 when I was knocked out cold for about half an hour and took some time to realize where I was and what had happened. One way to 'look' at things is as follows: What we perceive, feel and understand is a product of our material bodily structure and the many forces acting upon same. 'The Universe' is an aggregate of the above and give us a sense of who and what we are within the grander scheme of things. Now, let's put ourselves into the shell

Smelly cities

Watching a video of Imperial Rome reminded me of an experience I had visiting Singapore in 1971. Staying overnight in a modern hotel on the outskirts of the downtown, I ventured into the heart of the old city where narrow cobblestone streets had an open sewer running down the middle. In fact, if you approached the downtown from downwind, you could smell it a mile away. Eventually you get used to it but the initial impact is quite powerful. And so it was in Imperial Rome, a city with some 1 million people, many of whom lived in poverty and squalor. A hive of activity and breeding ground for all manner of infectious diseases. On the other side of the ledger, I lived in the City of Baghdad in 1961 where dry heat day temperatures in the summer ranged between 40 and 50 degrees Celsius. It did not have open sewers (the water would likely have evaporated) but the smell was so different, and not unpleasant, that I experienced it in my dreams long after having returned to Norway.
