Yeah stalker I meant Round Rock. When they use their unit it is always front and I can sense their KA at 1/2 mile or more. The other day I picked it up two streets over. Today I was driving and KA was going very low, come to find out two units were parked on a side street doing laser and left their KA on! 90* off axis detection, but there was a lot to bounce off and at angles conducive to me. Of course SA saved me, this area is notorious for Laser hits, I think they use it to train the new guys. The street is very long and wide with several side streets very low PSL given the conditions, so its easy to creep to 5+ on it.
Yet when I pass a DPS unit that is running the sensitivity seems much less (in the two instances). Also of note my windows - side and rear are metallic so I have to rely on frontal object bounce and do not get interior bounce from rear hits. Found this out in Milam (also a well known trap). Constable using K IO, saw him setup and he immediately proceeded to hit me. Passed him no more alerts yet in my rear view mirror saw him pull out to get a hog twenty seconds after I passed him.
I am very good at figuring which antenna is in use so the original post I still believe was his rear given the signal charactestics of when I passed him. But in retrospect he may have been slightly off angle, a maneuver they use on highways to buffer them from getting hit. So it is possible that played a part into this particular instance. I am still trying to get more hits before being concerned, its been difficult because the IX is more of a LEO repellant
jimbonzzz: You are correct by suggesting that transmission power is the same on all settings for the Stalker Dual. I had a chance to test this out - setting my Stalker from it's lowest sensitivity setting to it's highest setting. Detection range was very similar at all the settings for my 9500i so much so, that I would consider the differences insignificant.
However, the detection range for the Stalker unit did increase quite dramatically at the higher sensitivity setting. Again, providing credence to your comments. Thank you!

I've noticed a very low level Ka constant-on from some of the NYSP SUVs lately, mostly traveling in the opposite direction. They are typically equipped with Stalkers, but seem to emit about 34.9 GHz rather than 34.7. Normally, I'll pick up a stonger constant-on from 1/4-1/2 mile away, but a few times this past weekend it was a much lower level from only a couple of hundred feet. Interestingly, I paid attention the last time and the V1 rear antenna saw nothing as they passed -- so it's unlikely that they simply had the antenna aimed backwards. The level never rose above about 2-3 bars (less than half), and there were no other cars. I'm at a loss right now, but would love to solve the riddle. Can't wait to get my STi back so I can verify the frequencies.
o2bad455 - I thought I was crazy and have noticed this also. These new vehicles (Less than a month old) do not have the older Stalker Duals. they have the new DSR 2x from what I was told. At first I thought the gun on the first Suv was out of calibration because my STi-R did not alert to it, but the STi did. I was running my STi -R with band 5 only enabled and it did not alert (range is only to 34.808). The Sti reports the freq at 34.818 and another at 34.830. These results are constant and two SUVs I see a lot report these frequencies. I have since enabled segment 6 and the STi-R reports the same frequencies, but the alert time seems less with these SUVs, even on the STi-R. Because of this I have also shut off USA mode on the RX-65. I have yet to see them sitting and hitting people with I/O (just laser once). Mostly just see them driving around.
I wonder if the change in frequencies are due to the new Rear Traffic Alert on these systems? Perhaps the traffice alert is not designed to give tickets and is at a diferent frequency? Does anyone know anything about this?
Rear Traffic Alert is active when the patrol vehicle is most vulnerable to rear-end collisions--pulling into traffic from a standing start. If the Stalker DSR 2X Radar senses a rapidly approaching vehicle within adjustable speed parameters, it prompts the officer with a distinctive alert tone and displays ALERT in the strong and fast windows.
The Price on these things seems quite a bit, especially when compared to the Truspeed.

I . . . have noticed this also. These new vehicles . . . have the new DSR 2x from what I was told. At first I thought the gun on the first Suv was out of calibration . . .

Ditto. I've also seen a couple that my old STi actually reported over 34.9 (34.91X and 34.94X, to be more specific).

That's an interesting theory that the STi readings might support, but my V1 encounter (where new V1 rear antenna didn't see it after I passed opposite direction LEO) tends to disprove. I need more V1 encounters to be sure, though.

Today I was able to exercise my sensitivity with a K band mobile speed sign.
Approaching the sign from back (not facing K band antenna) 2/10 mile (poor)
Traveling away from sign (antenna) - 4/10 mile (acceptable)
Towards antenna, with a slight curve - 5/10 of mile - 1/2 a freakin mile (poor)
Is it just me or does it seem like I may need my new detector tuned? I mean this is a K band blasting away c/o. I would expect much better detection even with a slight curve. I also noted that even though it had only "seen" the sign twice it autolocked it out which scares me that it did so, so quickly. I even tried a reset and it kept the autolock setting. Thoughts? Are my expectations too high? I could swear when I had my 9500i I had insane sensitivity now I feel like at times I am driving around with a fancy brick.

Like Jim stated, it is the reception that makes the difference when adjusting sensitivity level with no difference in power output. This is the same thing with range setting.

Never argue with an idiot. They'll just drag you down to their level and beat you with experience!

No. Rear traffic alert is just a feature. The DSR 2X are 2 active radars in one single unit which can operate either the front or rear antenna's or can use both antenna's at the same time. This is the only radar unit that have this capability. All other radar units as of this date will only operate one antenna at a time. Although it has a spec frequency of 34.7, one can be off a little bit in frequency. If you look at the specs for the unit, they are stable at +/-100 mhz.
Here's a video of how it looks when you operate one.

No comment about AutoLock - I have not used that feature, since I've stuck with my i.
As for sensitivity.....that's hard to say.
What mode was your detector set in?
Also, are you absolutely positive that the sign is C/O? Many of the units I've seen, locally, are I/O in terms of operation. That, combined with their relatively low power (<--- this, though, is just from what I've read here and elsewhere, and may not be accurate; one of the other RADAR heavies here should be able to either confirm this or be able to correct me), may cause some reception/detection issues.

Thanks for taking the time to confirm. Hopefully, this will help to convince "non-believers", since I'm sure this will come up again in the future...
Highway mode. I reset it after a few runs to verify that there were no "glitches" with memory. Range and sensitivity remained the same. Mem-Tek do you think I need to send it in per your PM?
I have one more decent ride this weekend and should see some activity as I will be traveling through several small Texas towns and one very active DPS district around Milano.
