Ka 34.7 delay. Is this normal?

[seejay1120]

Sorry for the misunderstanding, but I did not mean that. What i meant by "standby" was that the gun was on, but not transmitting. Is it is possible that some guns may "leak" just enough signal to set off a good detector? I cannot remember where i read this, but if i remember it correctly, some older Ka units had stability problems in their design and kept some of the RF transmitter section "heated" to mitigate them.

Modern radar guns do not leak. I'm not sure about guns that would be as old as what you're talking about, but any Ka band guns used today are certainly recent enough to not fall under the catergory of needing a warmup period of any kind.

I really appreciate your replies to this topic, btw. Let me see if i understand this correctly. You are saying that no components of a modern traffic radar gun are "on" in any sense of the word until the LEO pulls the trigger. If that is not the case, is it possible for a radar gun to leak if it were incorrectly maintained (shielding improperly replaced, etc.) or was damaged in some way that did not affect its basic operation?

The reason i am asking all this is to determine some explanation for the scale of the signal response of the RD under the circumstances (very rare indeed). It was barely chirping while i was not 10 feet away and the gun was pointed forward. When i moved past, into the zone of the gun horn, the signal dropped off to nothing. Five hundred feet down the road, some 40-50 seconds later, the RD maxed out and continued to do so as i was parked at the gas station, even after the LEO has passed my location, just from reflected signals.

If they leak, it's not a leakage that is detectable by a radar detector. I have four radar units, and my V1 has never picked up anything from any of them unless they were transmitting.

Thanks for all the info. At best, my explanation is insufficient, at worst it's misinformation.

Heres the stalker I believe was used, its 2 directional and can be used one direction or another or both.


Rear Traffic Alert Warns Officer
Rear Traffic Alert, a proprietary new feature of the 2X, is designed to warn the patrol officer of rapidly overtaking same-lane traffic.
Rear Traffic Alert is active when the patrol vehicle is most vulnerable to rear-end collisions--pulling into traffic from a standing start.
If the 2X senses a rapidly approaching vehicle within adjustable speed parameters, it prompts the officer with a distinctive alert tone and displays ALE rt in the strong and fast windows.
Rear Traffic Alert is only available on the 2X and is a patent pending Stalker technology.

4 Target Zones in Stationary Mode; and 2 Target Zones in Moving Mode
Conventional moving radar can only monitor traffic in one Target Zone. Now, with the introduction of the Stalker DSR 2X, two moving Target Zones or all four stationary Target Zones can be monitored simultaneously. Stalker DSR 2X is actually two independent radar units operating on a single display.
In moving mode, two Target Zones can be simultaneously monitored - one front Target Zone and one rear Target Zone. In stationary mode, all four Target Zones can be simultaneously monitored. The direction arrows indicate target direction for both the front and the rear display windows. Or, if desired, only one front Target Zone and one rear Target Zone can be simultaneously monitored.

Measure closing targets while automatically ignoring vehicles that are going away - even if a target moving away is closer than a distant closing target.

View the Strongest and Fastest Targets Simultaneously
By displaying both strongest and fastest targets simultaneously, the Stalker DSR can monitor faster vehicles passing larger vehicles and display the speed of both targets simultaneously. The Stalker DSR utilizes three colors (red, amber, and green) to differentiate between the strongest, fastest, and patrol speeds.

Small Display / Counting Unit
The compact display and counting unit is small enough to be mounted almost anywhere. If an even smaller unit is desired, the display / counting unit can be separated and then just the display can be mounted on the dash.

Waterproof Ka Band Antennas
The Stalker DSR 2X includes two O-ring sealed, ultra-high frequency, Ka band antennas. These compact, completely waterproof antennas utilize locking, waterproof connectors and can be exterior mounted with no reliability concerns.

The Best Performance in the Industry
To maximize performance and range - the Stalker DSR 2X utilizes the most sophisticated microwave system in the industry, extensive noise and interference rejection methods, and the most advanced signal processing. The result is the highest performance police radar on the market. This amazing performance means you can monitor vehicles at greater distances, which results in a superior tracking history and better target identification.

Yeah thats what the NY State Troopers use.

So say the LEO was parked there looking for speeders. Would that delay of alert cost me?

No, because it sounds like the radar (though looked like it was facing you) was facing away from you. He wouldn’t of gotten your speed till you passed and he already had a customer.

[nyjason13]

Ok thats good. Thanks for the info!

Ok, after an experience just now, I bet that the delay before was normal.

I'm sitting at an intersection when I get an alert for Ka 34.7. No cop is in sight. I make my turn, and the alert goes away. A couple moments later, it alerts me again. This time I saw the cop in the distance behind me, approaching me, and he eventually made a turn. I'd say thats a good amount of distance for a rear alert. Now if I had a V1 with arrows, I wouldn't have had to guess where he was coming from . But I suppose that doesn't matter because I've become very fond of Spec Mode on the Escort units. . Moreover, both alerts were at a location with a TrueLock. I guess I've also grown to enjoy the quietness of the 9500ix.

Pretty good without a rear antenna. It takes some time to get to know the nuances of any RD.
I know I love the quiet of the 9500ix and spec mode, plus a few other features you will find fun/useful at some point.

What features? AutoVolume has proven useless against my stereo But automatic nature of TrueLock proved itself the other day when a LEO was sitting at an area that had been struck by lightning. The leo was smack in the middle of a locked out area running K band, which was being locked out.

While on the topic of TrueLock, what does the difference in frequency for a K band to notify in an area under TrueLock?
