In theory having the filters on are not suppose to affect range, but as we are seeing this is not the case. After seeing more testing and that of my own. The cr97 is a good flat ground detector, and of they can get some lockouts on there an ok city detector as long as the filters are on. It cant hang with the big dogs as votex put it, but at 250 I dont think that is what Mike's intent was/is. It's a step up from precious models. and hope to see it improve over time.
I actually think the CR97 is a very good city detector even without lockouts. I personally don’t like auto or manual lockouts because I have had both my R3 and my Escort products lockout real police K-band in lockout areas. I prefer manual lockouts over auto if I had to choose. I run my CR97 in Highway mode 100% of the time normally with both filters at 1 and TFSR on and FDSr off. My city’s and the neighboring city’s PD to the east normally use constant on K and Ka Band, and my CR97 normally gives me adequate warning with minimal false alarms in the city. I am going to turn TFSR off for a while and see how that affects the performance and false alarm “balance”.

I agree with you 100% I will NEVER use ANY type of lockout! The way these NC state troopers, deputy sheriffs and even town cops hide and shoot nothing but I/O in all flavors 34.7, 35.5, and K band in all sorts of different frequencies there's no way I'll even try running lockouts! These cops know about door openers and false alarms and hide right in the middle of all of it! They also love to hide just around the corner after a K band trailer and pop your @ss with a point blank I/O shot!

@Kennyc56, Where I live, almost all of my city’s PD and the neighboring city’s department, they normally just use C/O vs I/O. The Tennessee Highway Patrol is mostly I/O with some occasional C/O. Most of my city’s radar guns are permanently mounted, but they still have a few hand held K-band guns. After having real police radar being locked out several times (with Escort and Uniden products almost 10 times), I am done using auto lockouts on my Escort products, but I may still occasionally (and cautiously) manually lock out a signal here or there, but it just isn’t worth risk to me doing numerous and widespread lockouts. I personally don’t mind a little noise with my detectors in the city. I like running the CR97 in the city. I have turned off TFSR in my CR97, and I have noticed a positive difference on several K-band encounters this weekend. I will keep TFSR off for a while. I may just leave it off if I see a noticeable and positive difference in the performance as has been reported here in the Whistler threads by you and others.

No lockouts for me on the '97 isn't a problem. The way to mark a location works easy on the '97, so that's good to have. I never see LEO's on my local streets, but I stopped using the lockouts on my Redline EX when I noticed it was locking out areas on the highways! I realized it was picking up junk on overpasses and such. Scared me when I realized it. It would be cool if lockouts would engage at low speeds. Going 65 or 70 in a 55 with a lockout is really just asking for it.

Really? Jane and I love driving through Tenn.! When we go on vacation on our way to Az. I've gotten monster alerts on I-40 every time we drive on it! I've never been hit even once with I/O in Tenn.! Every alert has been mind blowing crazy @ss C/O, some of them up to 8 miles long! My Redline and R1 eat it up and get every alert in unison! It's a blast watching them fight it out over all of that C/O 34.7! And no, I haven't had even a hint of interference between the 2 of them! As soon as you cross those mountains and get back in NC however, it's back to a war zone! No C/O ANYWHERE!

They (THP) used to use a lot of C/O particularly in West Tennessee, but I have seen more I/O lately in West Tennessee. I did encounter a THP trooper last week using C/O. I definitely prefer the C/O versus I/O. I also see a lot of local drug task force Sheriff Departments working I-40 using a mix of C/O and I/O. I made a few trips to NC last year, and you aren’t kidding about the I/O used by the NC State Troopers. I encountered a lot of I/O in the Mountains.

My personal experience with my CR97 is that with the TFSR on, adjusting the filters higher has a more incremental (more drastic) adverse affect on sensitivity and warning range. With the TFSR off, I can adjust the filters higher, and I can still get good warning range, and I feel more comfortable with the higher filter levels.

@RoadDogg,
That is quite true for the rest of us as well.
One minor technical correction though - the quote in your post has my username as the source, but in fact that is a @Bossdad71's posting...

I actually had a multi quote with both you and @Bossdad71, but your quote disappeared when I posted. I edited the post before I posted it, and maybe I accidentally deleted your post before I posted it. I am not sure what happened, but thanks for the heads up on that.

No worries. I used common sense and figured what you meant. I just don't want to take credit for posts from other people. All is good.

I like the sensitivity with TFSR off from everyone's experiences & the videos (thank you all!) here. Still running it with TFSR off/FDsR on/all X/K/Ka filters at 1/Ka Max not engaged/City Mode/volume 1 or 2. If I am in a herd of fast moving traffic I don't think I'm a target. I get the beep, look up - see the ####'s & I know that it's a false. However, if I am on the open road without cars around & it beeps I slow down without even checking the display which was a hard habit to develop. As a side note, the laser detection works, but like I learned on RDF, it won't really save you. I had a Ka alert going into a curve with sparse traffic, I immediately slowed to 55 from 60 & then the laser alert screamed off. Immediately (I mean really immediately!) I saw was a NY Trooper who was oddly sitting perpendicular to the roadway. In City mode the ' 97 gives a full on laser alert. It grabbed my attention. I could have been toast if I was hauling. I now remember how deadly laser is. I wonder if he was testing out his new toys or the CR97 picked up a laser false. Either way, it's good to know that the laser detection is functioning.

Hi, all.
Just another "casual" 34.7 encounter with local PD. LEO is oncoming, at 0:19 of video, around a bend and downhill. Initial alert at half a mile. Judging by the sudden end of alerting after passing each other, I would believe it was an I/O, targeting the traffic ahead of me. With similar C/O encounters, I usually get longer alert with low signal after I have passed the source...
Either way, enough time to slow down if I was in a hurry.

I agree @Marty K, I think he decided to pop the beginning of that pack of cars ahead of you and dropped it as soon as he passed by you. Looks like they are beginning to learn how to use I/O in your area! Uh oh! That sucks! Welcome to my world! Your CR97 will serve you well against all the I/O they can throw at you, unless you're the first in line! learn to love rabbits!

Thanks for the feedback, @Kennyc56! You are correct, lately the HPs in the area are doing I/O, especially when moving. Also, if no one is ahead of me, I always slow down on curves, before overpasses, and when cresting hills - I know those spots are the where the LEOs hide...

On a recent trip, I took my R3 and CR97 with me. I used the CR97 about 75 % of the time and did “a false alarm experiment” with my CR97 by playing around with the settings in 20 minute increments on the interstate. This wasn’t scientific as I didn’t travel the same stretch of interstate for each segment, and I had different vehicles around me (this is just a real world experiment). This is what I experienced:

1) FDSr - On, TFSR - off, XK filter - 3, Ka filter - 2.
- 21.8 miles traveled in about 20 minutes.
- 12 total false alarms as follows:
2 false alarms were generic Ka (with one of the two showing FDSr #s)
1 K to Ka false alarm (FDSr #’s)
9 K band false alarms (with 6 showing FDSr #s)
- No visible BSM offenders or vehicles
- One real Radar encounter - 34.7 constant on - 1.1 miles - very good IMO given the terrain.

2) FDSr - off, TFSR - off, XK filter - 3, Ka filter - 2.
- 23.3 miles traveled in about 20 minutes.
- 2 total false alarms as follows:
The 2 false alarms were K-band
- No visible BSM offenders or vehicles
- No real radar encounters

3) FDSr - off, TFSR - off, XK filter- 4, Ka-filter - 1.
- 22.7 miles traveled in about 20 minutes.
- 4 total false alarms as follows:
1 long 5.9 mile K-band false alarm. I was just about to power cycle it when it finally stopped alerting.
3 generic Ka Band false alarms
- No visible BSM offenders or vehicles
- No real radar encounters

4) FDSr - off, TFSR- off, XK filter - 5, Ka filter - 2.
- 27.8 miles in about 25 minutes (I extended this segment about 5 minutes as I had a previous model, not the newest design, GMC Yukon XL with BSM set my CR97 off for about 3.7 miles with a K-band alert. The K-band alert ended when I passed the Yukon XL).
- 1 total false alarm which was attributable to the Yukon XL BSM.
- I had zero “unexplained” false alarms with these settings.
- The CR97 also successfully filtered a new Chevrolet Tahoe BSM, a new Ford F350 BSM, a newer Mazda CX series BSM (I could not see the number, maybe a CX-5), a newer Hyundai Accent, and a different previous model Yukon XL BSM.
- I encountered a lot of BSM vehicles in this stretch of Interstate versus very few (if any) in my other segments.
- No real radar encounters.

5) FDSr - off, TFSR - On, XK filter - 1, Ka filter - 1. These are my “typical” settings I normally use with my CR97.
- 23.0 miles traveled in about 20 minutes
- No false alarms
- The CR97 successfully filtered a newer Lexus RX350 BSM.
- No real radar encounters.

My takeaways from this brief and unscientific experiment in regards to my CR97 with filtering and false alarms :

1). With the TFSR on, TFSR does quiet my CR97 down in regards to false alarms. Although I didn’t have any visible BSM vehicles on this trip with the typical BSM offenders (Honda/Acura, Chrysler Pacifica, etc) with TFSR on, those offenders will typically give me a generic Ka or 33.8 false alarm.

2). With the TFSR off, increasing the Ka filter from 1 to 2 seems to keep the CR97 quiet relative to Ka false alarms.

3). With TFSR off, I prefer to have the X/K filter with a setting of 3 or higher to keep the K band false alarms to a minimum versus my “typical” filter settings of XK - 1 and Ka - 1 with TFSR on

4). My CR97 continues to give me a significant increase in false alarms with FDSr on. I know it is supposed to notify the user when it is being “interfered” with, but my experience with the FDSr on is just not positive. I am starting to think my CR97 FDSr feature is not working properly, but I really don’t need it, so it is not a big deal. As long as I keep FDSr off, I am good. I do know that most CR97 folks on here are running FDSr on which leads me to believe the FDSr feature on my CR97 isn’t working properly, but I may be wrong.

I need to get some more radar guns, and do some tests to compare range with different levels of filtering and TFSR on vs off. I also have noticed that keeping TFSR off over the last week or two does appear to make my CR97 more sensitive giving me increased warning range which a lot of people have been reporting.

@RoadDogg,
I don't think there is anything wrong with your FDSr feature. I believe it is buggy in general. It does provide extra info, but also does increase sensitivity - that's what I think is the bug. Extra info should not rely on extra sensitivity. That leads to the increased falses. I run this feature ON because my commute is usually on rural area, where too many falses are not a real problem. The only reason I use it is to confirm in a way that it is a false (by displaying the changing digits shortly after initial alert), and not a distant or brief I/O. If I am driving on any Interstate with heavy traffic and many semi trucks around, the FDSr ON is just not good at all - too many false alerts. Also, in such conditions I would have TFSR ON. It's the only way to keep it quiet.

@Marty K, That has been my experience too. With FDSr on in Interstate driving, there is quite a lot of falsing for me. I have had better success (in my limited use) with FDSr engaged on smaller rural highways. My CR97 is also quite “chatty” with false alarms when I run FDSr on in the city in more of an urban environment. I have had success running the TFSR off, but (as you suggested in a prior post), I have notched up the XK filter some and the Ka filter as well to keep the false alarms to a minimum. I am still playing around with the settings some to figure out my “preferred” settings in different driving environments. I have running my CR97 in the city the past day with FDSr - off, TFSR - on, XK filter - 5, Ka - filter 5. Just about as filtered as you can get. These settings are likely NOT endorsed by @Kennyc56...lol. I am just curious to see how it performs in “tricky” radar situations with it filtered to the Max. Most of my local city’s officers are normally always using C/O. I did get a .6 of a mile K-band warning with these settings. Just about as soon as I was about to crest a “hill” in rolling terrain, I received a K-band warning, and an officer was on a traffic stop in a Ford Explorer police interceptor with an older BMW 3 series pulled over in front of his Police SUV about .6 in the “valley” of the rolling terrain.

That is still good. Most of my real encounters in curves and hills are at about 0.5 - 0.7 mile range, and all of them are before I have visual. So it gives me enough warning to slow down. And that is what I care about.

I agree. Terrain often is a huge factor when it comes to warning range, and as long as I have enough warning to slow down, I am good. I had another solid K band detection in the city last night. 1.0 mile C/O detection in rolling terrain. I had FDSr off, TFSR on, XK filter - 4, Ka filter- 4, and the City Mode engaged. On the first leg of our 25 minute drive to meet some friends, I had both filters at 5 (and in Highway mode), and the CR97 was super quiet for the entire trip in the city with the exception on one generic Ka warning directly behind a newer Honda Pilot Elite with BSM. I switched the filters to 4 for the ride home, and I also put the CR97 in city mode. Again, super quiet. It responded to one K-band door opener, and the one officer’s radar referenced above.

On a side note, my display got “stuck” in dim mode. It would change to dark, but it wouldn’t stay in the brightest mode. I power cycled it several times, and I did a factory reset. Still no luck. I tried it again this morning, and the bright mode is now working. I thought I was going to have to send my CR97 back to Whistler, but my display seems to be working now. My warranty is good through September, so I am going to wait and see if that happens again before I send it back.

That is an odd glitch (about the dim). Couple of things I do not like about Whistler are the customer service and product development. I don't think they really care about customer feedback or improving what is already out there. One firmware update since the CR97 was introduced, with next to no info about what it fixed. I truly doubt it is so perfect that it does not need update. It's a good detector with few quirks, but worse is the lack of involvement from the vendor - at least to acknowledge the shortcomings of it and say yes or no if any of the bugs can be fixed...
I got used to mine CR97, but one thing is for sure - my next detector will NOT be from the same brand...
