Question, what is keeping police from using something like mrcd in place of traditional radar guns? Does the weaker signal of mrcd also equate to limited speed detection range?
These units are made for Europe mainly because we don't have huge distances to cover. They usually put them at the entrance of a village or at various difficult places around towns and cities but they are also used as mobile units (onboard or tripods). In the US the distances that an LEO covers are huge and these tactics are not adequate. So the more powerful units are prefered and MR/Gatso units are rare. If we consider the cost that's huge, the habits all LEOs have and the effort to keep US-based companies as providers of equipment, we can understand why there is a lack of this equipment.

I've also requested they give Multaradar alerts priority over speed camera and redlight camera alerts. Right now (and I'm pretty sure its the same with the R3) if you are getting a speed or red light camera alert it will not alert you to MRCD until the speed or red light camera alert is done. This can create issues with mobile units as they aren't always there and it's important to know when they are there. Easy fix though so no worries.
It's something that should be fixed ASAP. If it leaks in the LEO community it will be the new tactic used to catch RD users.

Good post.

Our MRCD units are not run by true police officers. They use special constables. They make about $20.00 to 23.00 per hour.

A normal police officer makes double, or more plus all sorts of benefits and retirement pension plans. We do not use the police force for Photo radar.

Thanks for the explanation! And on your second point, I agree completely.

Ok, 3 more runs from this morning. All of them had issues and alerted as K band rather than MRCD. Firmware 1.22


These two runs were especially dangerous as the K band signal was "mute memoried" from a previous false I had encountered.

Considering LEOs lurk here I'd venture to say that the cat's out of the bag.

@Dukes Thanks for sharing your testing!

Thanks @Dukes.
Kind of reminds me of the R3 when we were messing with the early beta FW leading up 1.46.

So they just mail you a ticket? Do you get points on your license? What if it wasn't you driving the car? How can you defend against an anonymous accusation days or weeks after the fact?

In the USA we're supposed to have "face your accuser" laws that have been used to challenge some of the automated law enforcement tactics, but I'm not that well informed on the current state of these laws.

Wow that’s scary. Question. What k band false are u getting in that area. I know there is a speed sign by the school there on 132ave and like 69st Is the rear horn picking that and auto muting it?


With my settings. My pro M doesn’t pickup any k band signals until I turn onto 132ave

It's like a parking ticket. They just charge the registered owner, no points on your license and your insurance is not impacted. Just a fine or "speed tax".

Yea... I think its a great example of why the MRCD issue needs to be corrected ASAP as clearly this scenario could have lead to a ticket. I do know Uniden has mentioned they are working hard to correct this and I've forwarded my findings to them. Both my R1 and R7 false there every time but I didn't look too far into where it was coming from TBH.

I think that's how our red light cameras are done in USA. Better chance of the accused just sucking it up and paying the fine.

That's what makes MRCD's and other similar low powered K band photo radars so deadly. Even more so in an urban environment where there are plenty of non LE sources spewing out K band. The second and third videos highlight the issue of where locking out/muting a spot can cost you a ticket. Even if you don't lock it out you don't have much time to decide if it's a false or real alert. Yeah, MRCD sucks.

Very true. At least with MRCD it’s a unique alert (unlike Redflex) so this lockout issue will be resolved once they fix how the R7 alerts to MRCD.

This is never an issue with the Pro M, Redline EX or Stinger VIP. No actual k band within my city limits so I just smash the mute/lockout button every time it goes off lol.

Does turning off k band also prevent mrcd alerts since it's technically part of k band?

They separate it even though it’s technically the same band (just FMCW). You can disable K band and enable MRCD to get alerts. I did see a slight increase in detection with K band disabled but the ones that are detected as k band are “invisible” when you disable k band. At least for now until we see the firmware fix.

Thanks! So the mrcd cutoff frequency is 24.100? If the cammer was picking up 24.086 with mrcd on and k band off the r7 would be silent, I'd assume, because it alerted to k band in those videos. Seems silly that we would need a firmware update for something so obvious. Is the r3 doing this?

No the there is no cut off. They analyze the signal and if it matches the MRCD signature then it alerts to MRCD instead of k band. I can only speculate but I assume it’s being over filtered and they may need to reduce it a tad so we can detect the other trucks currently alerting as K band. Again I’m just speculating.

R3 is good to go (apart from the hardware restriction) on firmware 1.46. Firmware 1.48 acts similar to how the R7 is currently alerting to MRCD.

If you go to the testing section, you can see the results of FW 1.46 and the other test with 1.48 against MRCD.

The 1.48 test is more telling of what your looking for in relation to what @Dukes is getting across. It’s kind of eye opening on what 1.48 did and why we do not recommend that FW for MRCD detection.

I get the same on the R3 with1.48 vs MRCT based photo radars- it initially alerts to K band, switches to MRCD, back to K, and finally back to MRCD. This did not happen on 1.46, which alerts initially and correctly to MRCD
