    Default Idea for radar detector...

    I had an idea that would eliminate false alerts completly. On the escort you can see what freq is being detected... so why no have an "setup" mode where you can drive around your city, get the falses, and then set it to ignore those freqs!

    Nice idea, but not possible, since a lot of devices are on the same frequency as police radar. If the Escort (or any other detector) alerts, it is alerting because the received signal is potentially police radar. If it was possible to differentiate between police radar and non-police radar based on the frequency, then detector makers would have implemented this long ago, and they simply wouldn't report any alert on a non-police frequency.

    Now, what you can sometimes figure out from the SpecDisplay, is the model of radar unit being used by certain police agencies:

    33.3 GHz Genesis II
    33.4 GHz photo radar
    33.8 GHz BEE 36
    34.3 GHz TMT-6F photo radar/Multanova 6F photo radar
    34.6 GHz PR-100 photo radar
    34.70 or 34.94 GHz Stalker ATR
    34.2 - 35.2 GHz Stalker ATR (freq hopper)

    It is possible that the detector will detect radar a little outside of the normal band limits. If so, this is likely a fail-safe in case you get targeted by a poorly calibrated unit that has drifted a ways off freq. Although you might be able to challenge the calibration of the unit later in court, an alert would be good in this case since you would still get a ticket...

    I know that my police station uses the frq 24.150

    I tried the frequency display around here and I didn't find it to be of any use at all. I have a better chance of spotting a false by signal strength. There's door openers and police radar both on 24.150 here so it doesnt' tell you anything.

    Uniden tried something sort of simlar to what you are describing on their GPSRD detector model. It combined a radar detector with GPS reciever. You could drive around and mark the falses and it would mark them by strength, frequency, and physical location. Would have been awesome but the radar sensitivity of the unit just wasn't that good. Good news is, cobra is working on something like that now, so may see the idea coming back soon.

    Cobra, coming out with a good detector? lol. I have had their 9600 version and it was alright. It was a good bang for the buck the fact you can get it for about 100$ on buy.com The pop was a joke, it went off all the time.

    I am really wanting to know why the radar companies have not thought more about this "marking of the false frequencies" I mean, if you know the band of the police radar, then dont block any of those bands- but you can block everything else and that would mean 100% no falses...

    Ummmm, the detectors only receive the bands with police radar in the first place, so there isn't anything else that can be blocked...

    X-Band Police radar=10.525 GHz +/- 25MHz (10.500 to 10.550)
    X-Band Motion Sensors=10.525 GHz +/- 25MHz (10.500 to 10.550)

    K-Band Police radar=24.150 +/- 100MHz (24.050 to 24.250)
    K-Band Motion Sensors=24.150 +/- 100MHz (24.050 to 24.250)
    (Sometimes 24.125)

    Understand?
    You should really be worried if your detector doesn't "false". If it can't detect motion sensors on the same frequency, then just how much early warning to police radar do you have? There's no magic technique they can use to completely get rid of falses, they can only delay alerts, not report potential alerts, cut sensitivity, etc.

    Yeah, I used cobra ESD9210, ESD9870, and XRS9700. Odd scenarios like around corners and radar from behind gave pretty short warnings, but for people that occasionally drift 5-10MPH over the limit, they'd be just fine. Sad thing was that in a quest to cut false alerts, they cut sensitivity on K band. They all had better KA range than K. The city mode on the 9700 was pretty nice. selectable K band squelch, high sensitivity when you need it, lower falses when you don't. They've got some good ideas and I think if they start to target the higher price ranges some again like they did with the XR series (XR1010 and XR1050) they could come out with some nide stuff.

    Yea but thats not true in all the cases. My town uses a 24.150 K band freq, I have yet to see anything else set it off on this frequency. If there is a door or somthing that runs on that band, then dont block it. Find out what radar freq your local police use. I mean cmon what would be wrong with this?

    My town also uses the 24.150 K freq on automatic door openers
