    My Samsung A900 phone keeps setting off my Valentine One radar detector. I
    had one other Sprint phone do the same. Valentine says the phone is spewing
    out something it shouldn't and this is common on CMDA phones. I do believe
    it is the phone as my work phone is an LG CMDA phone on Verizon and it does
    not set off the detector. One or the other has to go as it is getting to be
    quite annoying. Anyone else have this issue?

    Thanks,
    Stu

    speed and cellphones KILL.
    slow down and no need for the radar detector.

    Re: Samsung A900 sets off radar detector

    I hear ya bro but I'm not talking on the phone while hauling ass down the
    road. This crappy phone is on though and most likely throwing something out
    that interferes. Prior LG PM-325 didn't do it, Samsung SCH-8500? didn't
    either but had an earlier Samsung that did. With one bar max of signal
    strength at home and now this, Sprint may be a thing of the past for me. The
    V1 will always be with me though.
    Thanks anyway,
    Stu

    Interesting. I have the A900 but no radar detector. But I'm curious. Does
    the radar warning go off all the time every time? What is the range? Have
    you experimented by walking toward the car to see when the alarm would
    sound? Do you have the GPS function turned off?
    What if your phone is jamming the police radar. You would be invisible.

    As long as speed limits are set for the worst idiots on the road, there are
    going to be speeders. I suggest you refrain from being such a sanctimonious
    asshole.

    I would suggest getting an Escort Radar Detector and dumping the old
    inferior Radar Detector on Ebay. Escort Radar Detectors have the best
    rejection of non-radar sources and other interference. I used to have an
    Escort back in the days when I liked to speed and they rule!

    Re: Samsung A900 sets off radar detector

    The detector seems to go off when the phone's signal is weak and looking for
    another is my guess. In a urban area where coverage is good it hardly ever
    sets of the detector. But on my drive home though a more rural area it goes
    off like every few seconds. The closer the phone is placed to the detector,
    the more it will set it off. I've seen it go off as I'm walking to my truck
    at home from about 10 feet away. I have not tried turning the GPS off but
    it's a good idea and certainly worth a try. I'm not lucky enough to have it
    jam police radar

    After many, many Google searches I'm finding others report that their PCS
    phones are seeting off various brands of radar detectors. Seems to be a CDMA
    issue for some reason.

    Probably not a CDMA thing so much as a PCS thing.

    13th harmonic (odd harmonics probably much stronger than even) of 1857.7
    MHz is 24.15 GHz which is the middle of the allocated radar band. PCS A
    channel handset transmissions are at 1850-1865 MHz. It's just about a
    perfect (mis)match. Look in your area and see whether your provider has
    A or B channels. I bet it's A.

    When signals are weak and coverage poor, the handset is running maximum
    power and has the most distortion along with the strongest signal. These
    are the conditions for maximum harmonic generation.

    I've had several CDMA phones in my car and I don't believe they have ever
    set off my V1.

    I would get the phone replaced.

    I highly doubt that Sprint would replace the phone due to its (possible)
    interference with a radar detector.

    The problem would most likely be inadequate image rejection by the Radar
    Detector.

    Probably not an image since most detectors are single conversion
    straight to a baseband detector. However, it wouldn't take much 13th
    harmonic power to set the thing off and an A channel PCS handset is
    definitely generating some harmonic energy, particularly in a poor
    coverage region where the final stages are likely to be saturating and
    into maximum distortion. The only thing saving harmonic energy coming
    out of the antenna is probably low-microwave filtering which very likely
    isn't doing very well that far away from it's design corner frequency.
    The characteristic could easily vary from phone to phone too.

    (PCS A Channel 25 = 1850.75 MHz)*13 = 24.060 is probably in the of
    range of most 24.15 GHz center radar detectors. Most of them are pretty
    wide and/or search to allow for radar gun frequency variations.

    I think it might be an interesting test for people in PCS-A coverage
    areas (a good portion of Sprint, I think) to try holding their phones
    out in front of their 24 GHz radar detectors while in poor coverage
    areas. I wouldn't be surprised if quite a few phones do cause a false
    detection.

    Valentine, sad to say, is full of it.

    The A900 "spews" out things only in the 800MHz, 1.9GHz and 2.4GHz bands.
    Police radar operates in the following bands:

    X-Band: 10.525 GHz
    K-Band: 24.150 GHz
    KaBand: 33.4GHz - 36.0GHz

    and Superwide Ka: 34.3 GHz 34.2-35.2 GHz, and 33.4-34.4 GHz.

    None of these bands are anywhere NEAR the emissions of a CDMA handset.

    Not to mention, I use a ESCORT S3 Radar detector and it has never been
    set off by any of the CDMA or GSM phones I've used. Likewise, I have
    friends with PassPort, Cobra and BELTronics detectors who have also
    never had any issues. Seems like valentine is the only company having
    problems with this.
