Did you see the LEO, was it a legit KA alert?
Yes the KA was a Local LEO and the K was the false I previously locked out.Originally Posted by brian1972ct
My whole town is KA, So I have the best area to use TrueLock ("No Risk").
Even when you are in spec mode, it will still tell you the same info as far as alert is concerned with a new Ka threat. If you'll notice, the 9500i will not lockout Ka band.
Correct, but in spec mode it won’t say "Multiple frequencies detected" or show you how many frequencies are being detected. Only in Expert mode will it verbally tell you "Multiple frequencies detected" and show you how many. 8)
Re: I see
Just lock them both out. Only lock out those locations that you absolutely know are false alerting the detector. After a couple alerts, it will be silent. Most of the falses are going to be on X band anyway, so good luck bumping into a LEO tagging you with the X band signal.
Don't bleed until you're shot.
About the multiple bogeys only displaying one on the escort expert mode:
I am not saying that is not a possibility, but it should still show a relatively strong signal for the second bogey if it is still close or approaching in which case you should not speed up anyhow. Also, I have noticed a lot in NC the Hway Patrol when hauling *ss will run with their KA on full blast and it always shows two separate bogeys from the one car in expert mode - So does this necessarily mean (based on what you said) that they have to radars in two completely separate frequency blocks?
Thanks
Expert mode is smart but not that smart. Some K & KA guns will give 2 separate bogeys (Ghosting) when the signal is strong enough. It’s like an over flow of radar.
When ever I get multiple bogey alerts I just slow down too. :wink:
Description of the 9500I’s sensitivity & filtering system:
As we all know the 9500I has some unbelievable filtering of false alerts, and some people find Highway mode to be Farley quiet as well, even though Highway mode has full sensitivity.
In "H" mode there is no filtering.
In "C" mode there is strong filtering of X and weak K band signals.
In "A" mode at 15mph and less there is strong filtering of X & K band, and at 15mph to 55 there is a brief delay (less than a second) to see if there are any matching/pairs radar, like in/out door falsies. At approximately 55 and above there is no filtering/sampling at all.
The end result would be under 15mph strong filtering of X & K band, 16-55mph approximately 1/10 second delay if a paired signal is found, and 55 and above no filtering at all.
In a nut shell "A" mode works just like the "A" mode in the 8500x50 from 16mph trough 55mph.
The one big addition that i beleve Escort did to inhance the above is the horn on the 9500I is designed to help filter out those useless off axis falses “Detection range” verses “Sensitivity”. The 9500I has very good sensitivity but on signals passed 35 degrees the sensitivity starts to decrease(detection range is not affected and that’s also why “H” mode is still quiet). The horn actually takes into account for “Cosine error/effect” any radar more than 40 degrees off axis will show less than 80% of your speed so this is considered a low threat. For example if you are going 70 in a 55 zone and the LEO’s radar is 40 degrees off axis, his radar will show only 56mph. This dramatically reduces the falses from automatic doors without sacrificing real threat detection range.
I figured the angle of the walls on the horn at 15 degrees would equate to the off axis decrease. Because 15 degrees times 2 (each side at 15 degrees) plus add the antenna width so the total equals 35 degrees and that’s where the off axis starts to decrease (all horns seem to be similar).
For example:
Signals from motion sensors are, in most cases off axis from the side of the road, not sitting in the middle of the road facing you or very strong. So by just shaving a little off axis you maintain detection range with creating less falses.
Most falses will alert your RD for a couple hundred feet when you are near them because they are usually over 40 degrees shooting across the road. Now if theirs a LEO off axis down the road you will pick up his signal much, much farther. Even if he’s 40 degrees off axis he’s so far down the road when you receive his signal he's essentially only 10 degrees off axis. Because of this, detection range would be maintaned for around-the-curve or over-the-hill encounters.
A discussion of the M4 horn: http://www.radardetector.net/forums/...ns-please.html
Just some notes and observations.
Radar from a gun can acquire your speed in most conditions at approximately a maximum of 3000ft in moving mode, and a maximum 5500ft in stationary mode, how much more sensitivity do you really need? An extra 500, 1000ft, 3000ft? It only takes a few seconds to slow down. Besides the fact that the LEO needs to be able to make out who is speeding and 3000ft would be difficult to see.
If I pick up a real threat with 10 seconds to react on a less "sensitive" RD, and 13 seconds to react with a more "sensitive" RD, does it really matter when it only takes 4 seconds to slow down?
Sensitivity doesn’t equate to not getting a ticket, the ability to communicate a real threat and the driver’s reaction to that threat equates to not getting a ticket. Its ½ driver ½ the RD responsibility to prevent a ticket. The most sensitive RD in the world won’t prevent a ticket if it doesn’t communicate the real threat clearly and the driver doesn’t react correctly.

What evidence does anyone have that ESCORT designed the 9500i horn to have a limited off-axis view. Specifically how is the 9500i horn any different than the X50 horn?
The GOL off axis test showed limited off axis on the 9500I M4 horn. The 9500I and the X50 use the same M4 horn, im not sure of any specific differences. The M4 horn also seems narrower than the old S7 horn used in the original 8500's.
Actually it appears most RD's are designed to have a decrease in detection on extreme off axis. Its the 9500I's filtering and horn design combo that I feel makes it work so well.
