Do you guys know how the AFSPD feature works on the CR 97? I know it applies "max filtering" under a certain speed. But is this max filtering (x/k Filter 5 and Ka filter 5) and TFSR on? Or does it not alter the Ka filtering and just alter X/K filtering and not adjust TFSR? The manual does not seems super helpful in explaining this. It just says it applies the max filter but doesn't explain in detail what that entails.

The way I understand it, it does apply to all bands. However, I will call Mike b and get a solid answer

I've never even tried it! The only thing I run is the low speed auto mute function to keep the volume down a bit below 35 mph. I don't trust lockouts or low speed filtering, not that there's anything wrong with them. I want to get all of the alerts no matter how slow I'm driving and decide how to react myself! If I'm not mistaken, it applies max filtering at and below the speed you set, but I could be wrong. We'll see what @Bossdad71 finds out from Mike Batten.

I just got a reply from Mike Baton.

Having that function is like settings on 5 on all bands
That's what I thought. Now I know I ain't gonna run it! I'll never do anything to filter Ka band no matter what!

Thanks for bringing this setting up. I have never really paid much attention to or used this AFSPD (auto filter speed) setting or the AQSPD (auto quiet speed) settings although I remember seeing them in the settings menu on the CR97. I have been running TFSR off lately to improve K-band warning range as I feel TFSR on really holds the CR97 back (as others have reported too) as I see a lot of K-band police radar in my city. I do use my CR97 quite a bit in the city in my wife’s SUV when I am with her and my daughter, and they don’t like all the K-band noise from all the K-band door openers. I have other detectors with GPS lockouts, but I don’t typically use or trust GPS lockouts. Anyway, we ran a lot of errands yesterday at stores with K-band door openers, and I may give AFSPD or AQSPD a try at low speeds when I am with the family. I likely will keep these settings off when it is just me. I have also tried the city mode as well on the CR97. My “normal/typical” settings I usually run on my CR97 are X/K filter-1, Ka filter-1, TFSR-on, FDSR-off, Highway Mode. In my observation TFSR on helps the CR97 in terms of false alarms (as TSF on does with my R3), but the CR97 has more of a “performance penalty” with TFSR on vs off vs my other two detectors that I normally use (R3 TSF on vs off) and Max360c (TSR on vs off).

I use it also. I have come to the conclusion that I am in BSM hell here. (NY/Long Island). I must run my CR97 with TFSR and the speed filter on 40 to quiet it down. Lately running xk and ka at 2. Really quiet. FDSR is off. Lots of speeding traffic so range isn't an issue in this case. Also noticed that those pesky k/ka mix ups are infrequent. It seems they are driven by BSMs. If traffic opens up, I hit the menu button and TFSR is there for shutting off. I still find their interface the best. If they can just fix the k/ka mix ups I would love it. C'mon Whistler!!!

Wouldn't we all! I haven't even been able to stand running my CR97 since all of the tractors and misc. farm Eq have busted out all over this area. They are all spewing 24.150 which is dead in the sweet spot for K band police radar! No matter what settings I've tried it drives me insane! On top of all the K band falses it has added to the Ka K band mixup ten fold! I've been running my R1/ Redline "ghetto arrow'' setup instead running only Ka band segged to 5-6-8 on the Redline and K filter and city mode on the R1 along with 5-6-8 also. I try to run my 97 every day but end up throwing my kill switch over to my tag team. I sure wish Whistler would fix this damn K Ka deal!

It's funny, I never really thought about trying it with k off to see if it still mixes up k/ka. I never even shut off X. I will try shutting off X to see if maybe that is causing the mix up. Has anyone here done that? I wonder if the time it takes to scan for X is causing this. Shutting off K isn't an option when I go into upstate NY as that's the main source of income in some of those towns.

That's the problem! I've always had X band off, but if you turn K band off I'll bet money it will just still alert all the k falses as Ka band! When I shoot it with my radar guns however, it doesn't do this at all!

I have always had X-band off, with K on, and Ka Max Id on, Laser on. I still get the K/Ka mix up with a lot of the BSM offenders such as Honda/Acura and Chrysler Pacifica. Occasionally, a GM BSM may give me a K band signal, but about 90 percent of my Cr97 BSM falses are reported as generic Ka or 33.8. I don’t have 33.8 in my immediate area. One time I was using my Cr97 about 90-100 miles away in a small town, and I did pick up a 33.8 signal in a 30MPH zone. I was looking for a Honda/Acura BSM, and it was real police 33.8. Fortunately, I was near the PSL as I normally don’t travel through there, so no ticket. I have been back through that city several times, and they use 33.8 almost exclusively. I almost ignored it the first time through because of the Ka/K glitch.

Update! I turned K band off on my CR97 just for the hell of it and drove to work this morning. It's about 40 miles from my house to my job. I only had 1 Ka false and that was a semi! I might be onto something here! I had Ka filter on 0, FDSR was off, X and K band were off. I'm going to try Ka filter on 2 and see how that works. I usually would have had at least 100 falses on my way to work, both K and Ka band so this is a drastic improvement! It's also just a crutch because hardly anybody can run with K band off! I'm willing to risk it in the name of science! TFSR is also off, though it shouldn't have anything to do with it. I have low speed muting set to 35, and low speed filter is off, like always. I run Ka-Max ID also. BTW, I can't remember the last legit K band encounter that I had anyway!

Same thing here for no k hits. Maybe no K is OK :)rofl:)! I only see NY State Ka troopers for my higher speed driving. I ran with X off this morning and no difference. Still got a bsm as a ka. Switched to FSDR/xk & Ka at 1/ka max/no TFSR/City beep mode and liked knowing this is the best the 97 can do for ka. It still got a ka bsm. No eyeball on LEO. Upped it to xk 2 to see if that stops the mis ids with FSDR, I may raise xk up more or maybe even shut off K. I do find FSDR will push the ka bsms to ### after a second or 2.

You can forget about using FDSR in any form with K band turned off! I tried it on the way home and it went crazy just like always! It even shows K band even though it's off! With it off however it was as quiet as my Redline is with K band off. I made it all the way home with not even one false alert of any kind, once I turned FDSR totally off.

I don't know why it would do that with FDSR on and k off. Maybe FDSR has the priority? However if k is off I'm going for silence. FDSR will be off because of this when I try it. Thanks for that info!!! FDsR can silence a legit ka alert due to the muting so I prefer FDSR. In city mode FDSR makes it beep a bunch.

I don't know why I didn't try K band off with the 97 before now! There is no reason at all for it to still show K band with it off just because FDSR is on, but it does! It's a glitch that should not happen. X band doesn't do a damn thing whether it's off or not. I never run it, It's crazy enough without adding X band into the mix!
