TXCTG - Mt Calm Ka 35.5 Testing 02-12-2017

[HR][/HR]INTRO

Well, after last week’s testing in Waco, @Jag42 and I decided just one testing event was not enough. So we met again in Waco last Sunday to put these detectors through their paces some more. We had a new entrant this week, as Vortex sent me his Whistler CR93 to test. This time we decided to try a new course that we’ve never tested on before. New courses are always exciting, but fraught with the possibility of things not working out quite like you hope or expect.

[HR][/HR]THE DETECTORS

[HR][/HR]COURSES

As I mentioned, we decide to try something different. Searching Google Map for potential courses around the Waco area, we ultimately settled on a stretch of TX31 east of Waco, heading toward the town of Mt Calm, TX. As we did a few test runs, it became apparent that pretty much all the detectors were going to alert at same place. So we decided to do a stew test (results below) on this course. Here’s a Google Maps overhead and some pictures from the radar source point of view, as well as a course run at 2X speed.

We also ended up testing on TX31 closer to Waco proper. We parked Jag42’s car up on a hill next to the highway to use as the radar vehicle. The spot was good for parking the car, but was just southwest of an overpass where US84 crosses over and merges with TX31. We thought it would be interesting to see how the overpass in the way would affect detections. Here’s a Google Maps overhead and some pictures from the radar source point of view.

[HR][/HR]RESULTS



  • We were able to test 35.5 on-axis (more or less), 35.5 forward facing, and 35.5 from the rear.
  • We did do 34.7 forward facing, but were using Vortex’s Stalker 2 gun, and it may have been running out of juice towards the end. We got some anomalous results, so since we can’t be certain it the battery wasn’t running low, we decided not to post those 34.7 FF results.
  • First table for each test is sorted by detector so you can quickly zero in on a specific detector if you so desire.
  • Second table for each test is ranked ordered from first to last with range, delta from the leader and percentage of the leader.
  • Graph for each test is ranked ordered from first to last with range, delta from the leader and percentage of the leader.
  • All tables and graphs are color coded by detector.
  • Unfortunately, we only had time for one run for each detector (although we had more than one unit of some detectors), so if a detector got bit by a bad run, well that’s the real world sometimes.

Ka 35.5 Stew Test

No charts or graphs here. All the detectors alerted (and quickly) at the stew zone that was 6.2 miles from the radar source, except for the CR93, Rad 450 and American Radar. We drove towards the source with each of them and they all alerted within a 100 meters of each other at the 4 mile mark. [EDIT: I forgot to mention that because the 3 lower tier detectors were not alerting, we also pulled out my Uniden LRD450 - it passed the stew test unlike the CR93, Rad 450 and American Radar]

Ka 35.5 On-Axis Detection Commentary

  • As you can see from the pictures and the course run video, we had a nice high spot for the radar gun, but had an overpass blocking the signal. We were interested to see whether that might help separate the men from the boys.
  • Turns out the gun wasn’t really angled directly on axis. It was probably at least 10 degrees of to the right.
  • We were somewhat range bound by the course, but still managed some separation
  • Jag42’s Redline took the prize. My Redline had an unusual sub-par run.
  • The Magnums were right up there.
  • The V1 had a good showing.
  • The 9200BT also did well. Had have seen previous indications of its relative strength on 35.5 from @Vortex’s testing.
  • The RPSE didn’t do quite as well as we were expecting
  • The LRD950s were middle of the pack, which is fairly usual for 35.5
  • The XPs were close behind the Unidens, which wasn’t particularly surprising, although the XP’s have beaten the Unidens before.
  • The DFR6 with Ka filter on seemed to slip a little.
  • The Max 360 wasn’t particularly anything to write home about.
  • The CR93 and Rad 450 brought up the rear.
  • Unfortunately, we somehow forgot to test the American Radar detector.

Ka 35.5 Forward Facing Detection Commentary

  • Jag’s Redline was again on top. My Redline was ok (by Redline standards a bit weak). It has performed well on 35.5 before, so not quite sure what happened.
  • Magnums did well, except for my WB which had a bad run which placed it in the middle of the pack.
  • Again, the 9200BT turned in a really good detection for a detector you can pick up for $100 right now.
  • The LRD950’s were somewhat inconsistent, with one pretty good run and one middle of the pack.
  • RPSE again only managed middle of the pack. Not sure what was up with that.
  • The V1 was also in the middle of the pack.
  • The XPs disappointed a bit in this test.
  • The DFR 6 was not very good on this test.
  • The Max 360 also did poorly.
  • The CR93 and the Rad 450 failed to alert at all.


Ka 35.5 Rear

Ka 35.5 Rear Detection Commentary

  • This test needs some explanation. First, it was driving away from the source, with a large obstacle in the way – the overpass. So in general, it was a tough test to begin with.
  • In addition, the top 5 finishers were able to catch a brief reflection off a sign at the top of a hill and make their performance look considerably better than the others. The rest of the detectors failed to catch that reflection, and suffered accordingly.
  • The Redlines both caught the reflection, and that, along with their notable latch time, gave them the win.
  • Bith LRD950s manage to also catch a reflection, but their latch time wasn’t up to Redline standards ;)
  • Jag42’s WB Magnum also was able to catch a brief reflection and make it into the top group. My Magnums missed on the reflection, but their detection abilities, as well as a relatively long latch time vaulted them to the top of the lower tier.
  • The V1 and the Max 360 did very similarly with their rear antennas
  • The 9200BT did not do quite so well on this test, but still not bad.
  • The DFR6 did poorly in comparison to its siblings, the LRD950s.
  • The RPSE again did worse than we expected for some reason.
  • The XPs would have brought up the rear, but for the Rad 450, and CR93, which didn’t manage to detect at all from the rear.

[HR][/HR]
FINAL THOUGHTS

Another good day of testing. @Jag42 and I always have a great time doing testing, and checking out new courses is always interesting. I think the next time we come back here, we'll put the radar vehicle on the other side of the gravel pile and aim it a bit left to get it more directly on axis. Also, Looking at the overhead, I think we might be able to get some interesting results using the same source spot, but shooting the radar down US84, and using it as a course.

I will end with my usual admonishment: This is just one test. And in this case, it was only one run per detector, so no detector got the chance to show that its results might have been different on a second run. You need to look at various tests, by various people, at various times, on various courses to try to get to a complete picture of a detector. So make sure to do your research, look at as many tests as you can, and find out as much information as you can.

Nice presentation buddy ! This course was very hard for most detectors. FF was a tough challenge,and being Ka 35.5 too. As we do more challenges like this,we can determine the detector's weak points. Ka 34.7 was all over the place with the assumed low power Stalker II battery issue. We later switched to the Stalker ATR,right before dark. Most detectors redeemed themselves on a few runs like the RPSE,XP and others followed. We did not have time to re-run everything.We decided not to use battery handled guns anymore. Corded 12v guns are the way to go.Next testing will be with the Spectre Elite RDD and K band. Look for that in 2-3 weeks.


We have a good idea the American Radar performance is with in the low end class range. More testing will need to be done. We are really not impressed about it. The 9200bt is a steal for $100.

Looks like you finally found something that the WB Magnums can outperform their Packaged brothers on! :p

AWESOME testing guys and, once again, THANK YOU!!!

I don't run into 35.5 very often, but it's good to know my HD+ (remote version of the RPSE) may not excel in detecting it. Man, I hope it's not a hardware limitation... :eek:

The CR93 and Rad 450 brought up the rear.

The CR93 and the Rad 450 failed to alert at all.

The XPs would have brought up the rear, but for the Rad 450, and CR93, which didn’t manage to detect at all from the rear.

[MENTION=9768]Brainstorm69[/MENTION] , thank you for your efforts and thank you for permitting us to conserve our dollars on DNS (did not start) entries :)

[MENTION=201]Jag42[/MENTION] , is this a detector that one can live with on a daily basis when driving mostly in an urban setting?

Yeah, Jag42's WB seemed particularly strong on 35.5. Near the top on all the tests.

Yeah, I was surprised at the failure of the CR93 and Rad 450 to alert at all, although I guess if they missed alerting on the FF, then with the overpass in the way after that to start the rear test, it isn't that surprising that they didn't alert on that test either.

The 9200BT is interesting. For $100, I'm tempted myself. Although it doesn't have GPS for urban driving. And Vortex has posted some of its other limitations in the 9200BT thread in the Cobra forum.

The 360 has un-balanced performance. The 9200 is fairly quiet,but not as good as the XP.

If I may ask....why do you think the 360 did so poorly on this 35.5 test vs the last set of 35.5 testing where it did fairly strong?..... https://www.rdforum.org/showthread.php?t=56036
This was a different and harder course for the head-on test. And the 360 hasn't shown itself to be particularly good at FF tests in the past, for whatever reason. It did do pretty much the same on the rear test as the V1. And remember, this was only one test and only one run.

this last test made me snag the Spitting Cobra on ebay which is on sale for $98. Let's just say a post Valentines toy for me from me. Going to use this when I am on a passenger seat of a friends car on some trips, lol.

Best deal of a good DSP RD ! We will find out if the 9200 leaks on the Spectre Elite.

Given the fact that they both have rear antennas, the V1 and Max 360 didn't do all that great in the rear test, where they still got spanked by the M3 and Unidens.

seriously, for $100 you can't go wrong. i haven't driven with it long enough to say i would trust it in any situation, but i have had some nice detections. the laser falsing with the ALPS isn't a problem for highway use unless you are stuck in traffic. GPS lockouts would be nice though, but the DFR6 is twice as much and doesn't have them. either way, it's a cheap way to make testing even more well rounded.

Man, i didn't think humans were supposed to merge with machines for a few more years. looks like TXCTG got a head start!

I really don't need lockouts since I haven't been using it with my LRD950 and XP.

Thanks for doing 35.5. These tests seem to be similar to the performance I've been experiencing around here with the RPSE on 35.5, which is sad. Yesterday the WB Magnum I'm running picked up a 35.5 signal that I am almost positive the RPSE would not have seen at the same point/location. Unfortunately, I was just running up the street and didn't have my dash cam on to catch the detection.

Thanks! Doing some more digging (and understanding) I think I am grasping it better. What exactly is a 'stew' test? Could not find it defined anywhere on here?

These test will certainly help me pick out my next detector for the second car. :) Thanks.
