I understand the X band could be store door sensors etc.. but every once in awhile I'll get a K or Ka band when I know there's no cops around.

I hear some domestic SUVs with back up sensors are using K bands? Any ideas of what trips K band other than a speed gun?

 

Some banks use these bands for their automatic door openers or security systems.

Also, there are radar "drones", which are radar guns that sit on signs or poles that emit radar waves to trick people with radar detectors to slow down.

There are also some radar-based devices that are used to trigger traffic webcams to take pictures.

We have about 8 of these things here in Raleigh, NC on I-40. I haven't determined if they are drones or acting as a trigger for the webcams I see mounted above them, but they sure **** off my x50 no matter what mode I put it in.

 

yeah i've started to realize my detector goes off at the same points on 40..... i used to always be like "where is HE???" and then be confused

haha

 

Be careful on 540. Cops know that around 6 forks, and falls of the neuse rd there are enough x band signals to set off detectors. So they will sit right there waiting for the people who ignore the detector.

Maybe I have a cheap *** detector, but it seems Hwy patrol always registers x band, Raleigh cops K, unmarked raleigh pd X band.

They were out in force today counted 5 on the way to work this am. 2 at falls, 1 at leesville, 2 at 70 interchange.

Highway patrol uses K also. Raleigh PD uses KA as well.

 

I've noticed that certain radar detectors set off my V1 (K, and Ka), maybe its time for an upgrade.

 

just got mine yesterday and i have the latest update and it does it on mine too.

 

there are certain taillight lenses that can trigger the radar...gm and ford's especially

 

I used to have the problem with radar detectors setting off my old Cobra piece of crap $75 detector I got for a christmas present. ever since I got my x50 I cannot remember one time when this happened (although it could have happened and I didn't identify the situation as such).

 

there are drones on freeways which measure the flow of traffic. these use ka band. usually itll be a very strong signal out of nowhere and then itll disappear.

 

how can u guys see the ka k x L at night? i can only see the red dot and i kinda have to look close if it's a x k ka i wish the letter lit up.. N how do u adjust the lighting or can u?

ive seen this done, but if you just listen to the tones, its not needed.

 

I have an x50 and the tones are distinctive to where I don't even look anymore. At night I turn the display off completely.

 

I'm pretty sure some construction signs and equipment put out a warning on one of the bands.
