    My all-time high frequency readout on (LEO) K band was an unmarked pickup (with a customer) running 24.209 on Route 4 in Vermont (between Killington and Bridgewater) about 1 & 1/2 yrs ago.

    no worries. Nothing in here that needs elevation now

    I think right now radar gun company's are staying up to date with laser and newer KA band guns. Since K band is a single frequency +/- a small bit of range for error I don't see them setting guns close to the edge of where they can legally transmit. This would be a bad thing for them if units were to drift outside the FCC legal K band range. I don't see a company wanting to take that chance so they will tune as close to the correct K band frequency as possible.

    The band to take advantage of from a company stand point is KA band. If KA is divided up into 10 segments all they would have to do is change the assembly line frequency every 3 weeks jumping from segment to segment. Right now I think they pretty much use 3 set KA frequency's. See the chart below. If they mixed it up using all 10 segments that would be a real pain in the a$$ for detector users.

    Ka1 = 33.392 - 33.704
    Ka2 = 33.704 - 33.896 MPH 33.8 Ka
    Ka3 = 33.886 - 34.198
    Ka4 = 34.184 - 34.592
    Ka5 = 34.592 - 34.808 Stalker 34.7 Ka
    Ka6 = 34.806 - 35.166
    Ka7 = 35.143 - 35.383
    Ka8 = 35.378 - 35.618 Kustom / Decatur 35.5 ka
    Ka9 = 35.595 - 35.835
    Ka10 = 35.830 - 35.998

    Building on what you were saying though if for some strange reason they did want to think outside the box they might try the following.. Radar gun company's could try to market X band guns again claiming most detector users are turning X band off. They could also push K band guns claiming the signal will get lost in a sea of CAS and BSM signals. Since maybe 10% of cars on the road run a detector I don't really see any of the above happening. If anything they will jump ahead to newer technology. Heck today if I was an officer in a small town that had a large highway run past it I would have the department buy me a moving X band system with front and rear antenna. 100% legal on frequency and you would catch detector equipped cars all day long because most are running lo or no X.

    That is a very good point, and I can see that possibly being a main reason for not wanting to do it. Then again the LEO's in my town running around with K-band have yet to drift more than a few thousandths over the last couple years.

    I have to say I’m fortunate there’s no k band in my immediate area(NJ-side) anyway.

    K band is an annoying PITA. #1 because it’s usually a false, #2 if you’re in an area where it’s real, and you have to decide where it’s real.

    I hate k band.

    Unfortunately, my Benz AMG is broadcasting 24.200 all over the place and I have my ALP/STiR antenna ignoring K entirely. I use my Redline for K too so I see the freq since ALP doesn't give the freq when it's muting K.

    The few times I've seen MA troopers running K, it's usually been down pretty low. Always makes me think twice about K Narrow on road trips home.

    I think it goes Ku(nder) from 12-18 GHz, then K from 18-27 GHz, and finally Ka(bove) from 26.5 - 40 GHz, so it could be even worse o_O

    One thing I've found that's nice if you're a V1 user is setting K narrow from 24.100 - 24.200 so that most of the LEOs you come across that run K will be handled however you have your native K muting configured. The ones that run high will at least still provide a visual when running an app too. Highest LEO I've seen was 24.198 in my areas.

    Interesting! What year is your Benz? I've seen the older first-gen Distronic systems running on K band, but nothing since the mid-90s.

    I think word would eventually get out. There are some areas of New Jersey where they still run X and it's widely known about. Also, going back to X band would actually be really nice because no supermarket doors are on X band any more and none of the adaptive cruise/collision detect systems are on X-band so it would have very few falses.

    Maybe you were just putting this in a public forum to try to get some PD to implement it... perhaps I should have kept my mouth shut! :laugh:
