I met up with @NPark yesterday to do some testing at a course he had scouted out in NNJ. This was the first NNJCTG test of the season, and we certainly learned a lot that will help in future tests. Nothing earth-shattering here, but we would appreciate any feedback.

Actually pulling off even a short test like this is quite a bit of work, and it really makes you appreciate the sheer amount of time and effort that has gone into all of the RDF testing over the years. Big shout out to the TXCTG, @Jag42 @Brainstorm69 @Deacon @hiddencam @studio1930 @Dukes @Vortex and all of the other members that take the time to put together the amazing tests in this subforum and provide us with the valuable information we all use to compare detectors and decide on what to get.

The Detectors
Uniden R3 (1.37) - X off, K off, Ka on, Ka 2/5/8. (For X band testing: X on, K off, Ka on, Adv, X 100%, Ka 100%). @InsipidMonkey
Escort Redline - X off, K off, Ka on, Ka 2/5/8. @NPark
Beltronics Magnum WB - X off, K off, Ka on, Ka 2/5/8. @NPark
Radenso Pro M (US9) - X off, K off, Ka on, Ka Narrow. @InsipidMonkey
Valentine 1 (3.8952) - X on, K off, Ka on, custom sweeps. @InsipidMonkey
Escort Max 360c (latest fw) - X off, K off, Ka on, Ka 2/5/8, Highway. @Vortex

Thanks to @Vortex for sending us a brand-new Max360c for this test! It was still sealed in plastic when we received it, and was updated to the latest firmware in the parking lot right before testing.

The Course
@NPark picked out a course lined with shopping centers where we could leave the radar car parked for extended periods without drawing any attention. The course also allowed for an easy U-turn at one end, and multiple options for U-turns at the other end depending on detection range. Unfortunately, traffic and traffic lights were a bit of an issue, and slowed things down a bit. In the future we will probably look for a course with minimal traffic lights, and less traffic :)

Map of the Course
One goal of this test was to compare front and rear detections between detectors with front horns only to those with both front and rear horns. Thus we recorded detection distances for the four "detection zones" indicated in the map below. Zone 1 was driving away from the radar car (in the direction of the radar) to see how long a detector would hold a rear signal. Zone 2 was the standard test driving toward the radar source. We also noted detection behavior after passing the radar car, heading into the U-turn (Zone 3), and when the detector picked up the FF signal again after the U-turn (Zone 4). We didn't record Zone 3 and Zone 4 measurements for every detector/run, as most lost the detection between the light and the U-turn (around the Zone 3 arrow), and picked it up again as you made the left turn on-axis to Zone 4.

The Results
Test #1 - Kustom Golden Eagle Ka 35.5 GHz
We started with 35.5 testing, setup roughly on-axis. It quickly became apparent the course was probably terrain limited, however, as the R3 and M3s all turned in almost identical forward detection distances. Most detectors alerted just before the Jackson Ave light, just as before you crest a slight hill leading to the detection zone, with some alerting just over the hill. Traffic conditions were certainly a factor, however, and one Pro M run was likely somewhat obstructed by a large truck.

35.5Zone 1 (Rear Detection)Zone 2 (Front Detection)Zone 3Zone 4 (FF Detection)
R30.56 / 0.540.77 / 0.750.20-
RL0.500.77 / 0.750.210.20
Mag0.540.77--
Pro M (GPS off)0.510.64 (partially obstructed)--
Pro M (GPS on)0.550.67--
V10.600.700.270.19
360c0.40, dropped, then full alert 0.48 dropped again @ 0.550.68, went full alert @ 0.51 miles with no ramp-up / 0.570.19 (intermittent alert)-

Test #2 - MPH Python II FS X band 10.550 GHz
Next we wanted to get in a few runs on X band to see how the R3 without an LNA compared to the V1 with an X band LNA. X band was turned on for this test (obviously), and the R3 was running Advanced mode with X at 100%. Here, the V1 picked up the longest run of the day, with a rear detection of 0.85 miles. The officially recorded forward detections were the same, but after reviewing the video it looks like the V1 alerted a few times before it was called out (around 0.80 miles). Again, nothing earth shattering, but it's good to see the R3 X band detection has been restored after seeing the poor results with an early firmware version.

X BandZone 1 (Rear Detection)Zone 2 (Front Detection)Zone 3Zone 4 (FF Detection)
R30.73 - 0.740.75Held to U-turn-
V10.850.75 (0.80+?)Held to U-turn-

X band Testing____________Distances in miles__________Run 1/Run 2__________"-" = N/A

Some notes:
The DTR radios performed quite well, with a maximum range of about 1.3 miles in this terrain.
Interestingly, when transmitting near the Golden Eagle 35.5 unit, an RFI error would pop up on the counting unit. The Python X band unit didn't show any errors.

Videos for all runs will be posted in Intermediate once I figure out how to access-restrict the RDF media player will be posted in this thread soon.
The cheap $27 Cobra dashcam (with built-in GPS) I used here worked really well, and it was nice to have a video record of all runs as well as GPS coordinates for every alert. Since this test had so many confounding variables, distances were reported to the hundredth of a mile. However, using the GPS coordinates from the video in future tests should give us very accurate results.

Edit: @NPark's notes:

Firstly, before you knock me too hard, up here in NNJ, *during the day* it is hard to find a course without traffic. I, also am still in finals. So we had to deal with it.
Not as much separation as we would've liked to see, but the results are what they are.
When we get these videos up, you'll see what it really looks like in a real world sense. Hilly, and obstructed kill-zone.
The x-band gun puts out ALOT of juice. Even in the U-turns we were till getting alerts(after zone 3- into U-turn).
Next tests will be down by him, and on a more open course.
The M3's held right with the R's.
The others weren't super-far behind either. Way way enough for a save. But as noted, the ramp-ups on the 360c, and the M were almost non-existent.
V1 and the M3's had nice ramp-ups.

As for the Radios, those we also have clips of.
The range was around 1 mile. We actually were out of range on the course in some far spots(and the radio bonked out).
Great, crystal clear audio, and very easy to use. A plus for these 900mhz, UNMONITORABLE(thats right, no eavesdroppers) digital radios.

Please leave us some *friendly* criticism/comments.

Oh! Almost forgot! As for the arrows.....BIG HELP.
The V1 has an incredible rear antenna. Over a hill(opposite side) still detecting. It certainly can and would help on rear rolling radar.
Sometimes as we all know that 1-2 seconds is enough to be/not be a ticket.

Imagine pulling out of one of those shopping centers and getting the alert regardless which way you turn. V1 SA esé !

Correct me if I am wrong......the R3 beat the M360 with the source behind it even though it does not have a dedicated rear ant like the M360?!

On one run, yes. The other was pretty similar. Keep in mind traffic was highly variable during this testing, and likely impacted the results. The 360c was also oddly dropping alerts completely then picking them up again at full strength at times. I believe we had all quiet ride settings disabled, but maybe @NPark can check the detector and confirm? When the videos are up you'll be able to see exactly what we're talking about.

Agreed. I can check that.

Also since time was short we didn’t have a chance to do the usual 3 runs each.

Too many variables to make this a “perfect test.”

The V1 did pretty good on this test!

Also when you can run the K band off on the Redline it is something else.

Awesome that guys, great work! Always nice to see that the V1 is far from obsolete.

Did you happen to run the Pro M against X band? Curious how it performed as I made some assumptions it would have trouble on that band and got poopoo'd by some.

Thanks.

Ran out of time.

That’ll have to be next time.

While in the radar car checking speeds, there were a ton of cars that floored it from that traffic light you can see in the distance and passed by at >>PSL. Clearly not a lot of RD users in the area.

Very nice job,and presentation ! I should have sent Godzilla to play, if i had known. V1 is very lethal on X band with it's LNA. It can beat the R1/R3 in TXCTG testing.Thanks for your time !

@InsipidMonkey and others wondering this course is in Wayne NJ.

This is Hamburg TPKE. Not to be confused with Hamburg NJ. Lol.

Could this be a future test challenge? Having a K band (only) test site set up in a busy, commercial area satured with K band signals? Which device can successfully show a source that's of a most immediate concern...
