Definitely would have been a ticket. PSL: 50 MPH. I was traveling 80 MPH at initial alert. Nice save by the R7!

Nice!
I just got R7 yesterday, and running same settings as you, except TSF is ON.
Only couple of hours driving so far with it, but absolutely loving it...

50 MPH on such a straight stretch? Pure revenue collection.

I don't have a R7, but I do use a R3. If TSF is the same between the two models, you can turn it OFF unless you're in an area that uses K-band traffic monitoring devices (not the occasional "YOUR SPEED IS" sign, but an actual traffic monitoring system. Otherwise, TSF ON slows down your K-band detection time without providing any benefit.

Yeah 50 MPH is a joke. The road does have some curves to it at times, but the limit should be at least 65.

As far as TSF On/Off on the R7, it doesn’t seem to have much penalty with it on, but I think it also depends on what type of terrain you deal with and for the majority, my terrain is tough, so I always keep it off.

@LeftLaneInPA,
Thank you for the tip about TSF. For what I have read so far, my understanding is that it does not really affect performance of the R7 (as compared to the R3), and the benefit is that it actually helps reducing BSM falses - which is the reason I have it on. But I would definitely turn it off and see how it goes. I also drive in area with hills and curves, so detection range and off-axis are important to me.
@mattguy10, I also agree that 50 mph is artificially set that low. How many people would actually resist and drive as slow on such a road? Have you noticed if the TFS ON helps reducing BSM alerts?

Yeah 50 MPH feels like you’re standing still on this particular road, which is why I’m at 70-80 quite frequently. TBH, I have never experimented with TSF on. Above when I mentioned it not having much of a penalty with it on, I was going by what I’ve read here on the forum. BSM falses aren’t really an issue for me as I don’t mind a little chatter (it lets me know my detector is working) and I’m not located in an infested BSM area. On an 80 mile drive, I might pass by one CX5 and one CRV, and now with K Block, only the the CX5 would be the issue.

Sounds good, thanks for the info. I will definitely try the TSF OFF...

Let me know how that works out. Since I posted that, I see that @Vortex recommends keeping TSF ON for the R7 since it doesn't seem to impact performance. And he definitely knows much better than I.

Very nice save!

Yeah as for TSF, I remember it being helpful for filtering out BSM's when first starting to run the R7. IIRC, @Brainstorm69 did some testing with TSF on and off and didn't notice much of a delay or impact to performance.

I did a test with TSF On and Off and it didn't affect the Ka band performance.

TSF only affects K-band.

I can’t speak for the R7, but I normally run TSF on in my R3 as I think it helps with BSM filtering, and my R3 is still a beast on K-band. I don’t think it has any affect on Ka band, because my R3 is just incredible on Ka band with TSF on. I ran my R3 today, and it is an absolute beast. I had a few Honda/Acura BSM false alarms on my trip today, but it was quiet other than some real 34.7 Ka encounters. I wish I would have had those R7 arrows today....lol . I had TSF off for a while, and I noticed an increase (not a huge increase) in K-band false alarms (I had forgotten I had turned it off), and I turned it back on, and my R3 went back to “normal”. I would try TSF On vs Off and see what works best for you. Enjoy your new R7!!

Exactly, but I felt it was important to mention the extra filtering seems to not affect the scan cycle times, which would affect the performance on Ka band.
That’s fair, but the reason TSR typically affects performance is specifically because it filters out brief signals. This makes it more vulnerable to QT. It also means that it will not alert to weak sporadic signals at a distance and will only alert when the signal gets stronger and more consistent. This you’ll see it impact ultimate detection range too, but that only applies to K band.

@OBeerWANKenobi testing here showed a small penalty with TSF enabled on the R7 on this particular course. The terrain on this course is what I’m used to and can be much worse than this at times. The brief and weaker signals are the ones I’d prefer not to miss, but I’ll enable TSF and keep my speed lower for a while to see if I notice any difference and if not, I’ll consider keeping it enabled full time.

@LeftLaneInPA,
Yesterday, I drove with TSF ON in the morning (30 miles), no BSM alerts at all. I turn it OFF on my way back (30 miles), and had only 1 BSM alert (alerted twice, for a couple of seconds each time) at 24.160 and 24.163. Too many vehicles around, could not tell which one was to blame...

Thanks for the info, @RoadDogg! I did turn it OFF yesterday for my way back home (30 mile drive), and had only 1 false. I will keep it off for some time to gather more stats. One thing I do is to log the frequencies I encounter on K band, so I can have a reference of the local environment...

@LeftLaneInPA,
After few days driving with TSF OFF - One thing that is for sure is the BSM falses: I do get more of those. As far as range, I cannot yet say. I only had one real K band encounter (I/O at half a mile, with slight bend and dip between). I've been keeping track on the frequencies I get from BSMs:
24.069 and 24.073 - Cadillac Escalade (front, when oncoming)
24.081 - Chevy SUV (front, when oncoming) - not sure of model, possibly new Tahoe / Suburban
24.123 - Mazda CX-5 (rear, when oncoming and passed by)
24.160, .162, .163 - could not confirm the vehicles (front, when behind them)
24.165 - automatic doors at a supermarket
24.168 - Chrysler Pacifica (rear, when oncoming and passed by)

The LEO was 24.121

Settings: K wide, K filter ON, K Block ON

Very interesting, @Marty K . Thanks for experimenting and sharing with the forum!

Just an FYI, and I'm not nit-picking, but stationary K-band falses from stationary sources like automatic door openers aren't considered "BSM". "BSM" is short for Blind Spot Monitoring. Essentially the systems in cars to prevent people from making lane-changes into occupied travel lanes.

Automatic door openers use what is essentially miniature police K-band radar emitters and can't be filtered out like BSM systems. Under most circumstances, you'll have to lock them out using the GPS function of your radar detector, or narrow your K-band detection range (i.e. "K-band Narrow/Wide") to filter them out.

That being said, great job!
