There were 3 LEOs (all back to back, no other vehicles between them). I believe it was the 2nd one that flipped the switch, but I am not sure if I was the target or the vehicle in front of me...
I did not look to see the frequency, as I was looking ahead and trying to see how many they were.

Good morning.

Here's another encounter I had this morning. I believe this is the kind I have not had so far - an I/O that was not at my face, but rather away and off-axis. Ka 35.5. Unmarked SUV at 0:39 (end) of video:

That was the only source I saw. I did look all around, and there weren't any BSM sources either. Also, as confirmation of the source, see this video (same unmarked vehicle at 0:19) - this one I am not sure if it was C/O or I/O for the traffic ahead of me, given the terrain:

Here it is.
Ka 34.7 C/O - around a curve and couple of dips. LEO was on the red traffic signal when I had the visual:

I have been keeping TFSR off, xk at 4, ka at 2, ka id on, ka norm, voice off, FDSr on, AUTOFILTER at 40, and Hiway mode. I feel that its really sensitive but not annoying because it goes silent if FDSr gets a BSM. This is for urban type highway use at 65 to 70 while 55 is the psl. I keep the volume at 1 or sometimes 2. It took awhile to sort it out but I like it this way. The k/ ka mixup seems way less with TFSR off. I do notice that if FDSr is not engaged, it has a tendency to hold on to a signal and not let go for awhile. I don't see that that with FDSr on. It is pretty sensitive and the FDSr silent feature makes it not too annoying in traffic.

I haven’t been using my CR97 too much over the last five weeks or so, but I have been using the CR97 the last two days. I don’t like the FDSr feature, and I normally leave it off because on my CR97 it causes a huge and significant increase in false alarms. But to get back on point, I did have an encounter yesterday where I had to “power cycle” my CR97 because it kept alerting way past the radar source, and it seemed like it “latched on and wouldn’t let go on the alert”. I haven’t really had an issue with this in the past. It was strange. After I power cycled it, it went back to silent, and it worked properly. My “normal” settings I run are FDSr off, TFSR on, XK filter at 1, Ka filter at 1. I may turn TFSR off for a while to see how that affects performance/false alarms.

My settings are almost the same, just one lower on the filters (XK=3, Ka=1). And I ,too, have found this to be the "best" compromise between reactivity and false alerts. This setup is great for urban environment, as you said. But if you are on a major Interstate, or on a road with dense traffic, then this becomes annoying pretty soon...

I have had the "lock-up" bug few times, and it has happened with both FDSr ON and OFF. All of them were caused by BSM sources to best of my awareness. Something to do with overdriving due to very strong signal (and very close by)...

That (BSM) is what caused my issue yesterday. I passed a new Honda Accord that gave me a generic Ka signal, and it was still giving me that signal long after I could not see the Accord. Once I turned the CR97 off and then on, all was good and no more Ka signal. Thanks for that information. If that happens again near a BSM source, I will power cycle the detector sooner.

You are welcome.
In addition, it's good to do a factory reset from time to time and have a fresh start. Normally, we shouldn't need to do so, but it seems like when the unit starts acting up, a reset takes care of it...

I have done the factory reset at least once. I likely will go ahead and try another factory reset. I haven’t been using my CR97 too much lately, and the issue of latching on to a signal hasn’t been an issue for me.

I haven't had any issue with any type of lockup with my CR95 or 97. I try to remember to do a factory rest about once a month or so. For some reason my Whistlers seem to work better if you reset them from time to time. It doesn't seem to matter on any of my other detectors. The only time I had a lockup was in my CR95 when we were testing it and I turned off FDSR. It locked it up and it wouldn't pick up any radar or let me do a reset till the next day. It made one half @ss pass that day, but the range dropped off to next to nothing. Once it let me reset it, it has worked great since!

Hi all.
This is the 2nd time I encounter K band in my area. Makes me a bit worry. I have XK filter 3, because I have TFSR OFF (it's my way to deal with false alerts while trying to get better reactivity). LEO was the 3rd vehicle in the oncoming traffic (0:17 of video). At first I thought it was a BSM alert (the 2nd vehicle you see on video), but in fact it was a real one. Range was almost non-existent, but it was around a bend and out of sight...

Range was almost non-existent, but it was around a bend and out of sight...

That looked to be a fairly sharp bend/curve. I watched the video several times. I personally wouldn’t be too worried because of the terrain, but I know we all want the most warning and range possible. I did several runs against a K-band trailer (not solar powered) with the CR97 a while back that is positioned several tenths of a mile around a sharp curve, and I changed the X/K filters on each run (TFSR was on), and changing from filter 1 to setting 3 almost reduced the range in half (from around .6 of a mile to around .3 of a mile). Changing the X/K filter to 4, I was reading my speed on the K-band trailer before the CR97 alerted. Whistler hasn’t been known for being a K-band range and sensitivity King. I have had quite a few K-band encounters with the CR97 that were very good, and I have had a few that had me a little worried. I know changing the X/K filter isn’t supposed to delay things much in theory, but I cannot bring myself to go past 1 after playing with many different combinations, but I also normally run TFSR on which I think most everyone else on here keeps TFSR off which is the default setting. By the way, great video!!

@RoadDogg,
Thank you for the feedback! Yes, I have TFSR off. I have never had a chance to experiment with TFSR ON and different XK filter levels, as I know it does affect Ka, and I try to avoid that at all costs. With XK filter 3 I had a 1.5 mile detection on a solar powered K band speed sign, but it was on a straight and flat road. The most I have had on Ka (34.7) is 1.7 miles, and about a mile on 35.5.
And by the way, @Vortex's test results are up on his website (latest posts)...

I did see Vortex’s test results. Thanks for the heads up on that! I normally run my R3 with TSF on and my Max 360c with the TSR on, but it sounds like the CR97 does take a “performance penalty” with the TFSR on based on other’s experiences. Next time I get on the interstate, I will try the TFSR off to see how it performs in terms of performance vs false alarms. I have tried TFSR off before, but it has been a while. On a side note, it is hard for me to remember the different acronyms that each manufacturer uses for TSR, TSF, TFSR, etc. Hopefully I got it correctly above.

I just think that Whistler's settings (TFSR, FDSr, etc) are not as quite fine-tuned as other brands. Thus, the different outcome. I know (from reading the forum, not from my experience) that other brands are still performing very good with TFS / TSR being ON. Whistler does show quite a difference there. That is (probably) why the filter levels from 0 to 5, where other detectors just have band filters ON or OFF.
If you try the TFSR OFF, most likely you will have to adjust XK and K filters to avoid too many falses...
No problem on the acronyms - as long as there are T, S, R letters put together, we all know what that stands for...

Here's what I got this morning:

Video 1: FF 34.7 C/O in dense fog from 1.7 miles. Initially displayed as 34.7, then (when passing the semi) displayed as 34.0. At the end of last alert - brief 35.5, just before locking out a BSM false (K band ####):

Video 2: Not about a range here, but picking up reflections, at about 70-80 degree angle. LEO was parked at the pump (gas station is to my right, as I am turning left at the intersection - 1:34 on video):

That very well may be the case. My R3 and Max360c don’t seem to be adversely affected by running TSF/TSR on, and I leave it on to help reduce false alarms. That is also why I keep the TFSR on my CR97. I normally run both the X/K and Ka filters at 1 with TFSR on, so I will keep that in mind (increasing the filter settings) if the false alarms increase too much with TFSR off. On a side note, I did a factory reset a week ago on my CR97, and I had another continuous K-band “latched on” signal two days ago. My CR97 picked up a K-band speed sign, and keep alerting long after we were way out of its alerting zone. No BSM cars or Police with k-band around. I power cycled the CR97, and the detector was quiet.

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.
