MRCD Radar Speed Cameras in NSW - really?

The AU/NZ distributor of Escort Redline EX International recommends MRCD and MRCT to be turned "on" in NSW and QLD--academically speaking of course.

Is there actually any Jenoptik MRCD Mobile Radar Speed Cameras operating in these jurisdictions? Has any Forum member ever detected one and had a MRCD alert (Audible and Visual)? Do any Vids (DashCam recordings) exist on YouTube?

QLD: The Stealth "Camera Trailers" are the only Mobile stationary Radar in QLD. They are Redflex slant radars using the British AGD340 Doppler Radar. The speed-reading frequency is 24.087 GHz which confirms its identity with certainty.

NSW: The "tracking radar" Speed Cameras used in NSW for many years (originally installed in Ford Territory SUVs) are Redflex. There could also be MRCDs as a supplement to Redflex. Proof is required!

Turning on MRCD and MRCT reduces sensitivity on the conventional Radar Bands such as Ka6. Why do that if there is no need for dedicated "resource-hog" scanning of FMCW Radars -- Jenoptik MRCDs?

@winterbrew can answer this for sure. Pretty sure there are MRCD based cameras around Perth.

There is no MRCD/MRCT I am aware of in Queensland or NSW...

NSW used to have a multi vendor approach to speed cameras, they used to use Redflex and Jenoptik however no longer use Jenoptik.

Queensland has some Redflex (NK7) on trailers that get moved after 2-3 weeks, though Poliscan and Jenoptik S350 lasers are used in typical mobile speed cameras.
The Redflex Wall-E looking trailers can vary from 24.087 to 24.105, they employ frequency hopping.

Cairns was the last region to use the old wet film Gatso's, as far as I am now aware Poliscan and S350 are used state wide.

To expound on that a little further it also seems the firmware used in S350's now matches that used in WA, I get pretty decent range on them now with my Stinger and ALP.

The Redflex (NK7) is the AGD340 Phased array - patch antenna "doppler" RADAR that is horizontally polarized. It's not a FMCW RADAR sweeping several frequencies very quickly.

Is the Redflex NK7 really "frequency-hopping"? This AGD 340 RADAR detects speed at the lower frequency and then (if the speed does not vary by more than up to 3KPH) tracks the vehicle at the higher frequency. The RADAR is designed to detect many vehicles in close proximity over several lanes. It's hard to believe that the lower microwave frequency would be sometimes "off" when that part of the RADAR detects the speed of all vehicles across the beam area?

It seems that the NK7 (actually AGD340) is difficult to detect due to three (3) factors: 1. Low power output; 2. Angled away from the traffic flow (rather than towards); 3. Horizontally polarized (when most Radar Detector antenna horns are vertically polarized).

Yeah I believe it does frequency hop, so I'm told by someone I would consider an expert on the matter.

I suppose he could have been wrong, but I doubt it.

In regards to detection, placing horn horizontal or vertical seems to make no difference, especially with my Stinger, I've spent quite a bit of time working with Stinger devs on that.

We showed in NZ against redflex we consistently get about double detection range by mounting vertically. This can also be demonstrated by parking outside the range of horizontal and picking detection and/or loosing it again as the orientation of the detector is changed.

Here is an early example...


In this case the radar is facing towards the car.

It is harder to pick up redflex when the radar is facing the other direction. However, we also tend to find the detection is also better for that direction also [when mounted sideways].

@dudeinnz has shown me similar videos in the past too, my R3 shows no difference horizontal or vertical, neither does my Stinger.
They typically are used on 4 lane motorways here too, so I guess the other thing at play for us is how it is aimed across 4 lanes rather than two.
They are mounted more how you would expect to see a Poliscan 35-45 degrees depending on placement., I fully concede if it was aimed more directly down the road as yours appear to be results on my end would probably be much different.

Ultimately running a window mount RD here is asking for trouble, so now and then I do for testing.

Interesting. Perhaps I'll do more testing. However, for us, the R3 is useless against redflex. Almost all our vans operate below 24.05. Even the latest R3 firmware cannot fix this limitation which by all accounts seems to be on the hardware.

Like yours, usually the beam is off axis. Most of the time we get really good range is when it's pointing more down the highway, or (like in the video) you have a location where the road passes closer or through the beam in the distance.

Therefore, I'll run some more tests on the DFR9 and R7 comparing horizontally and vertically. As you'll see in this next video, I'm also impressed with the detection even where there is a decent chunk of scenery blocking at least part of the beam:

Oops, sorry I see we're going a bit off topic.

Turning on MRCD and MRCT reduces sensitivity on the conventional Radar Bands such as Ka6. Why do that if there is no need for dedicated "resource-hog" scanning of FMCW Radars -- Jenoptik MRCDs?

I used to have a Redline 2015 Intl aka Pro A with MRCD and MRCT detection, and I know it was said then that switching these on was a major resource hog.

Is this still the same however with the newer gen Escort detectors such as the Max 360c Intl and Redline EX Intl which use much more powerful processors than in the original Redline-O.

I remember seeing claims that the Redline-O Intl / Pro A had different hardware to the North American model, but when people disassembled them both, there didn't seem to be any physical difference on the circuit boards?
