- Yes, it is a receiver. No, it is NOT totally passive.
- Superhetrodyne receivers have a local oscillator.
- It tranamits a very weak signal, but it's very real and detectable.

- This is starting to sound like a "Get Smart" episode
- with the anti-anti-anti missle missle.
- I believe that the cost of each level of counter measure is higher
- than the level it's detecting, and its accuracy is lower.
- Each detector radiates less power, requiring a more sensitive
- detector to detect it. There is a point of diminishing returns.

- Football strategists understand this.
- You have somebody with the ball.
- There are opponents trying to tackle him.
- You thwart the offense
- 1) indirectly: fake or deceive the offense to out their effort elsewhere
- 2) directly: block the offense
- Try to take it a level beyond that and you have to take manpower
- away from the direct objective into purely support roles.
- That's why there's a limit on the number of players on the field
- at any time.
-
- Military thinking doesn't understand such things as limits on
- manpower, supplies or money, but that's another story.
- So don't declare electronic warfare on the traffic radars.
-
- Why I don't enjoy speed traps, I feel that it is very wasteful to
- wage war on police radar. The radar is only a tool for law enforcement.
- If the countermeasures get sophistocated (detectors, jammers, stealth)
- then the police will up the ante and spend megabucks
- on more equipment and specialists.
- I'd much rather the police put their efforts into crime prevention,
- but if radar is rendered effectiveless they will try other methods
- of enforcing the speeding laws. Please don't bring this upon yourself.

- Ah yes, Western Union.
- I recently worked across the street from their building in lower Manhattan.
- The building speaks of a spendor and elegance that's long past.
- My grandfather was a Western Union telegraph operator so there's
- some affection for the company that didn't see the handwriting on the wall...
