R7 seems to be more chatty than the R3

Mazda was kind enough to start spewing at 24.160, smack dab in the middle of K band which was where we would typically see LEOs. Hondas and GM are usually 24.198 and above so it was easy to disregard them. Thanks Mazda! As always, K band came from Satan's anus.
Although the CX-5 I saw the other day was 24.123.

Yeah try TSF on. I found it more important with the R7 than with the R3.
Does TSF on slow reactivity on K band? I hope not enough to matter.

Yeah that's where I've been running it too. I did the R3 at 70% and I do the R7 at 60%. Just seat of the pants stuff, nothing super concrete with the different settings, but it does seem natively a little chattier. Maybe the rear antenna, maybe it's more sensitive, I'm not sure why.
I did definitely noticed that 80% of my K BSM or what have you falses come from K rear even with advanced at 40%.

@DrHow - Initial testing indicates K-band reactivity is fine with TSF on. Check my post in intermediate.

Just saw your earlier one referencing that. Thanks for pointing out. Heading over now.

This is probably a dumb thought, but once we have auto lockouts enabled, won’t that quiet it down? I assume it won’t help with BSM, but a lot if my R3 K band hits are related to door openers, etc..

Auto lockouts, if you choose to use this feature will just make it so you don’t have to manually lockout false alerts like door openers. You assumed correctly as far as BSM goes, auto lockouts have nothing to do with tackling BSM systems as they’re not always stationary like door openers are for example.

My R7 came in as well and I desoldered the horn. It's more chatty than the R3 because it doesn't have any additional DSP processing power but has twice the horns, it's basically literally two R3 stuck together (one of everything per horn on the circuitry). I am surprised they did it this way as it adds cost to the BOM, but probably saved engineering time as opposed to coming up with a new design to share a central DSP.

One interesting thing is that they used a slower (less powerful) dsp chip for the rear horn than they did for the front horn, which is the same one in the R3 (400mhz blackfin).
Is there any way you could share some photos of the board with the horn desoldered? This would complete the pictures @ShadowTrooper posted.

The answer is that we don't know if TSF will affect range or reactivity a lot yet since there hasn't been enough testing in this area.

I suspect you won't see much difference with a clean signal on a straight road. The devil will be in the attenuated signals. I'm basing this on testing the R1 and R3 as it follows it should be similar at the moment with little FW divergence. Reactivity needs more testing as well. Wish I had my R7 and I'd get to testing right away.
Stay tuned!

I did in post 50, that's the DSP board that was underneath the horn.

If you are planning on desoldering the horn (not really the horn, but the PCB that allows the horn to be removed), I would really recommend using kapton tape and a hot air station. I did it via a standard soldering iron (my hot air station was at home and I couldn't wait) and it's really difficult with a standard iron since you need to desolder three through the hole pins at once. I managed to lift a pad unfortunately that has K band acting wonky after I soldered it all back together again.

Snapdragons are great but they aren't powerful enough in certain ways for what we are trying to do. Hard to explain without giving too much away. I know that sounds crazy considering they are many orders of magnitudes faster than what is out there in terms of clock speed currently, but clock speed isn't everything.
Having done SOC work in the past, this is very interesting!

While it would probably be a total waste of money, I wonder what effect the Blue Raider would have on BSM systems.

My testing indicates that K Filter and TSR on for the R7 is not really a problem for K-band I/O
Awesome to hear. Police only use K in my state. I need to block as many BSM alerts as possible, but still have good reaction time to Police K

Actually, I would say that BSM's come from Satan's anus. What genius decided to put them at the same frequency as police radar? FCC regulations I assume. IIRC, Vortex posted a while back that in some very near future year, they will put BSM's on some other frequency that doesn't match police radar.

The reason they used K-band is because it's unlicensed/unregulated, so anything can operate in that frequency. Thankfully, they are moving to the 77GHz range so they can have higher resolution radar in the future. 76GHZ to 81GHz has been licensed for automotive radar among a few other things.

I have to admit, when you pass a car headed the other direction and the BSM triggers the rear antenna, it is very annoying.

Can't say it's any worse than other detectors outside of the Pro M. I run mine at k 50%

I run my R3 on Narrow, city, TSF on 1.37 Quiet Ride 45.

It is quiet as a mouse. I hope Uniden can achieve 1.37 silence on the R7.

I’m thinking Uniden should add 20% to Advanced and drop City to 10%. Especially after seeing the results K band test.
