Correct - I noticed a few weeks later when I saw the same car number that the unit was replaced with a new DSR2x. I think there was something really wrong with that unit that drifted so high.

I am still thinking that it is possible someone at the state is tuning these radar guns to some of those frequencies. NYS has its own department that services and certifies the radar units (which I think is a conflict of interest, should be an independent 3rd party)
So is Seg 7 still valid for NY or has the "bad radar gun" been replaced?

I'm sure there is more than one "bad radar gun" in NY :p

At this point, I have NY as 1/2/4/5/6/7/8 which covers just over 75% of the Ka Band (only missing segments 3/9/10). At that point, does segmentation matter? Are you losing any response time to filtering/segmentation vs just running the full Ka Band?

You are loosing a miniscule amount of the percentage of time spent scanning all "ON" segments as you add. The greatest advantage to segmenting is eliminating falses in the "OFF" segments

I run 2/4/5/6/7/8 1/3/9/10 off.

The only real benefit I find now for running segments is to get rid of some of the falses you may find in segments 1 and 10.

I dont suggest anyone run 2 detectors, but my remote detector runs segment 5 only - no K. So if I note the windshield mount alerts, while the remote does not - it is an out of spec signal -(or the R3/R7 tells me the frequency)

I have noted 2 alerts out of spec this week (same car I think), both in segment 6, but who knows what others you may encounter.

The R7 does not have segment 10, just 1-9. Anyhow, I thought this other post was interesting when talking about segments.

There's some really good threads where people are talking about needing extra segments or wider sweeps, typically for Stalkers that transmit at 34.8xx or even 34.9xx.


It'd be handy to have a quick reference guide for the locations where people have seen confirmed radar guns that would require additional segments. Running 2/5/8 is the norm, of course, but let's cover the exceptions.

If there's anything funky that people have seen in a particular location which requires additional segments, it'll be listed below. (Read through the thread for more details and specifics.) Otherwise the standard 2/5/8 sweeps will be fine.

Alabama: 2/5/6/8: Segment 6
Alaska: 2/5/8
Arizona: 2/5/6/7/8: Segments 6 & 7 for reservation police with older ATR's
Arkansas: 2/5/6/8: Segment 6 around Omaha
California: 5/8: 2 not needed, 5 very common, 8 rare and almost unnecessary
Colorado: 2/5/8
Connecticut: 2/5/8
Delaware: 2/5/8
Florida: 2/5/6/8: Segment 6
Georgia: 2/5/6/8: Segment 6
Hawaii: 2/5/8
Idaho: 2/5/8
Illinois: 2/5/6/8: Segment 6
Indiana: 2/5/6/8/9: Segment 6 & 9
Iowa: 2/5/8
Kansas: 2/5/8
Kentucky: 1/2/4/5/8: Segments 1 & 4
Louisiana: 2/5/8
Maine: 5/8: Segment 2 not needed
Maryland: 2/5/6/8: Traffic cameras may need segment 6
Massachusetts: 2/5/6/8: Segment 6
Michigan: 2/5/6/8: Segment 6
Minnesota: 2/5/8
Mississippi: 2/5/8
Missouri: 2/5/8
Montana: 2/5/6/8: Segment 6
Nebraska: 2/5/8
Nevada: 2/5/8: Segment 9 in Caliente
New Hampshire: 5/6/8: Segment 2 not needed, add Segment 6 for 95
New Jersey: 2/4/5/6/8: Segments 4 & 6 for drifting Stalkers around 34.5 & 34.8
New Mexico: 2/5/6/8: Segment 6 for 34.8
New York: 2/4/5/6/8: Segments 4 & 6 for drifting Stalkers around 34.5, 34.8, & 34.9
North Carolina: 2/5/8
North Dakota: 2/5/8
Ohio: 2/5/8
Oklahoma: 2/5/8
Oregon: 2/5/8
Pennsylvania: 2/5/8
Rhode Island: 2/5/8
South Carolina: 2/5/8
South Dakota: 2/5/8
Tennessee: 2/5/8
Texas: 2/4/5/6/8: Segment 4 in Carthage, Segment 6 in Dallas
Utah: 2/5/8
Vermont: 2/5/8
Virginia: 2/5/8
Washington: 2/5/8: Segment 7 in Pierce County for a 35.2 Stalker ATR
West Virginia: 2/5/8
Wisconsin: 2/5/8
Wyoming: 2/5/8

Alberta: 2/4/5/6/8: Segment 4 & 6
British Columbia: 2/5/8
Manitoba: 2/5/8
New Brunswick: 2/5/8
Newfoundland and Labrador: 2/5/8
Northwest Territories: 2/5/8
Nova Scotia: 2/5/8
Nunavut: 2/5/8
Ontario: 2/5/6/8: Segment 6
Prince Edward Island: 2/5/8
Quebec: 2/5/8
Saskatchewan: 2/5/8
Yukon: 2/5/8

Note: False alerts on other segments can happen, especially with the Ka filters disabled. When reporting weird frequency alerts that you see, please confirm that it's actually coming from a police officer, not just that your radar detector displayed an unusual frequency.

For reference, here are the frequency ranges for each segment:
  • Ka1 = 33.392 – 33.704
  • Ka2 = 33.704 – 33.896 (33.8)
  • Ka3 = 33.886 – 34.198
  • Ka4 = 34.184 – 34.592
  • Ka5 = 34.592 – 34.808 (34.7)
  • Ka6 = 34.806 – 35.166
  • Ka7 = 35.143 – 35.383
  • Ka8 = 35.378 – 35.618 (35.5)
  • Ka9 = 35.595 – 35.835
  • Ka10 = 35.830 – 35.998
and here's an explanation about band segmentation in general.

Thank you! Added.

Mods feel free to keep updating the OP as well should you see additional suggestions or changes as well. Thanks for the last update you made that I just noticed! ;)

If you live in West TN and get out much you could easily be in KY, AR, MS, AL, GA and if you plan to scan for each just to be ready you are only left with 3 bands not scanned. (3/7/9) Is that still better than Ka Wide? I assume since its still a filter but thought I would ask.

True this ^ ^ ^ the real benefit is turning RDR OFF and leaving it off. Its simply NOT needed. I still run 2/5/8 ON; RDR OFF and have never had an issue in the near 20 years that I've run segmented detectors (Stir-O, RX65 S7 and Redline).......

Just turn 2/5/8 ON and leave the rest OFF. Turn RDR off and you'll be fine.

I was the same way @PointerCone ! I finally bit the bullet on a recent trip to Pa. when we got smacked with several Stalkers above 34.850! I know that they were legit because I saw each of the cops in northern Va. Two of them hit me with I/O shots and the other one was sitting in a parking lot with both his antennas running and both of them were above 34.850! I'm running "ghetto arrows" so I looked at my Redline-O in the back and it matched my R1's reading in the front almost exactly! This trip was the first time I've ever ran 2-4-5-6-8. I did it just for the hell of it. I've since left all of my detectors set up like this and haven't noticed any drop off on range or speed, but I still don't like it! Just for the record, all of the Stalkers in NC that I get hit with are spot on perfect! None of them are low and the highest I've seen here is around 34.74, and that's usually a rear antenna.
