Escort 8500 X50 question

[Jonathan19]

I just bought my Escort 8500 x50 about a month ago and had an encounter the other night that had me begging for more. I encountered a ka band on the highway and about .5 after the detector went off i saw the leo facing the same direction i was traveling. then, after another .5 mile it dropped out. all the while i was still able to see the leo right behind me.... :cry: is this normal? i know ka is hard to detect but....

[crazyVOLVOrob]

yeah thats 100% normal and how most constant on encounters occur

[Orbital75]

Yeah, this is true...... In fact I just had a KA encounter tonight and
just as you said .5 and this was even contant on. It was around a
small curve so that could have decrease the range a good but this
is normal for the X50......

Another thing you may want to look at is the freq your local
LEO's use. Our LEO's here in Charlotte use 35.5 and the
X50 doesn't do that well on that freq.

ya, I get that everyonce and a while too...like everyone else said, its normal

Very smart man there orbital75 you know your stuff. Yes this is very true some detectors are better on some frequencies than others. This is shown in alot of the guys of lidar testing results on their page this is why they show the frequency results even for ka band. To show you which detector would be better for your area because some detectors scan differently and pick up certain frequenies alot quicker than the next. In the end you are gaining ft on the enemy which is always a plus!

Also i firmly beleive that 35.5 mhz is one of the hardest frequencies to beat. Due to the fact that it is right in the middle of any bandwith scan figureing your working like a scanner starting at the top or bottom and working your way through the frequencies. The other one that im noticeing by testing results that is hard is 33.8 because it is on the lowest side. And from what it seems most detectors start on the high side and scan through you can see this by looking at the testing results on GOL and visually seeing that the detectors are picking up higher frequencies first! Meaning they are scanning from top to bottom! The gun manufactures are taking all the advantage of this they can by running 33.8 which is almost the lowest you can go within the allowed bandwith of police radar for ka with the lowest allowed being 33.4 ghz. This is just one more tactic the radar gun companies are using to make their guns even more deadly and effective on the ka band as if they need to be they are already making some not get alerts till its almost too late.

cobras suck harder than a playmate!

hmmm, I always though 35.5 was harder to detect because it is usualy found on the lower power output guns like decature and such. The scan you are talking about probably would make too much of a difference alpine, considerign to catch pop it has to complete a scan every 67ms, blink and youve missed it so I have a feeling it has more to do with the power output of the gun and scenario of the encounter and less to do with the scan of the detector. Just a hunch though. Otherwise most detectotrs would suck on 34.7 because thats in between the 35.5 and 33.8 which you say is towards the bottom of the scan and as we all know most detectors own stalker's frq.

But you certainly have an interesting theory, I would be interested in what Jim has to say about this matter.

Your answer is more logical.

If you look at the lab sensitivity results, sensitivity on 35.5 GHz isn't generally a whole lot different than it is for the other Ka freqs:

The scenario of the encounter makes the most difference with the range you get. The different power outputs (or other design differences) of the guns do matter, but to a much lower extent.

As for the sweep: Most detectors can sweep all freqs between 250ms-950ms depending on the detector. To catch POP, they'll generally do a "priority sweep" on 33.8 (some on K-Band), hitting it at least once every 67ms.

The frequency's place in the band doesn't make any difference as far as what is detected "first" or "last", since you could first encounter the radar when the detector is at any point during the sweep.

250ms-950ms depending on the detector

That's nearly a full second! :shock:

I have looked and can't really find any good info on how exactly RD's "scan" frequencies. Any good references you know about?
