I reckon there could be some value in that.
We'd just have to design the test.

Ideally park the radar gun and an operator 1.5-2.0km apart. have a man in each car, one to swap out detectors at one end, one person to fire 1 second quick shots from the other end. We could do this anywhere we have cell phone coverage for communication between both stations.

It's all do-able

Hey guys, I was thinking what about this idea.

Radar car or mounted on a tree somewhere.

Then car1 which is the kill car.

Then our car which had the RD.

The radar operator would i/o when the kill car reaches a certain spot, while the RD car maintains a distance to see if it catches the burst of activity?

A bit over complicated? I just drove 400kms, so could be hallucinating

Sounds good.

We also need to have the burst of KA band timed. With our ATR's we can lock on the transmit, then kill the power supply, then start it and it will start transmitting immediately. I've tested this.
So we plug the power supply for the gun into a timer i know of that will allow us to switch the power on for precise periods of timer, right down to one second. I will even research a millisecond timer in case we have to go shorter.

Yea, I agree. The more variables we can control the better!
I think I/O testing might be easier said than done. I think we would need to try it out and see what works best. Anything is possible ;)

Jeez, I go to Oz for a week and all hell breaks loose on our forum. It's only radar detectors guys, not religion.

Demon5, one thing I've learned in 30 years using detectors, nothing is as good as repeatable, consistent testing over a set course. I've had detections in the "real" world that made me think my detector was a POS, and others that seemed like it would detect an alien fart on Mars.
All on the same unit. That's the nature of the beast.

On another subject, sorry to be a pedant, but the V1 is not the latest, although there should not be a difference with the 3.8952 units, apart from being able to push a single Ka sweep.
Was that V1 swept, or using factory default? Was Ka guard off?

PS. Did you do any runs at illegal speeds?

Actually Lou we had two V1s, I sold one the night before flying out so the one we tested may actually be 3.8952, can verify on Monday night.

V1 was custom swept.

Ka Guard was off.

No illegal speeds.

I can't wait till we move back to the Top Island and I can come and play.
I don't mind doing illegal speeds. It'll be interesting to see any effect on range.

Just thought I'd post abit of an update/small observation...

I am finding the R3 will hold on and continue detecting 34.7 from behind after I've passed the source for alot longer than my Redline ever did..
I'd say it's almost up to how I remember my V1's being with rear detection after passing the source, which is saying something due to the V1 having a dedicated rear antenna.
Anyways, just an observation I am seeing on a very regular basis and possibly an idea for the next round of testing from NZCTG :)

and i thought i was dreaming that my r3 does exactly the same. mine is also way better than my redline once the source is passed.

@shadow69, yes quite noticeable isn't it? Redline used to fade away pretty quickly once past the source..
On a side note did you see the post I tagged you in about R3 camera alerts being directional now?

so it must comedown to the type of reflection its picking up, other cars, trees, buildings etc, in the absence of a rear antenna... certainly would be a good test a 'tiger from behind' scenario...i remember heading heading South towards Merermere for the drag racing, and a cop was hidden tucked far up on the left hand side on ramp shooting his Stalker 34.7 South, the same direction as i was travelling, but my V1 at the time alerted me to him even though i couldn't see him, until i passed and saw him in my rear vision mirror!

thanks just seen it now.

problem is i an pretty sure the the r3 alerts when im on the wrong side and dosent alert when i need it to. it may also have to do with the fact that the old removed camera is in the db and is about 300m apart. r3 alerts to old camera but not the new one.

Ok from what you originally said is that the camera is aiming south and you only get an alert while heading north. This makes sense as you would be driving into where the camera is aiming.

So I recieved a redline original I purchased off RDFORUM that was made in 2015 and having it segmented 2/5/8 yeilded exactly the same results as our redline pro a. This was tested on the same course using the same equipment as the orignal testing but performed today.

0.7km from the starting point of our test course both detectors alerted. And no we did not test them at the same time.
3 runs each, rounded to the nearest 100m.

So it appears the additional features on the pro a, if not enabled has no detrimental impact on the redlines performance.

4 lane motorway (2 north,2 south) camera on south lane facing south so appears to be targeting rear of cars. large concrete median barrier but camera may high enough to cover all 4 lanes but i reckon its only covering the 2 south lanes as is looking down the road instead of across the 4 lanes, but i could be wrong.

so the r3 alerts to new redflex camera when driving north then another camera alert 10sec later to where the old camera was years ago,

when travelling south alerts to old camera but no alert to the new camera? seems like a bug that couldbe caused from 2 spped camera alerts withing about 300m.

If that's a pole mount Redflex, it will be covering north and south lanes. The Ngauranga gorge one can monitor three or four lanes each way and identify individual vehicles.
