For all of you Whistler owners out there and even some of the other brands this might give you some insight into why your unit may false.
After seeing the test results from my PRO58 on POP Mike from Whistler contacted me and wanted me to send in my detector to make sure everything was in spec.
Heard from Mike today and he said it was in spec and gave me some insight as to why these units may false
Here is what he had to say:
The falsing problem is unfortunately due to the 9,
10, and 11 band Cobra models and other models built around the 9 band
platform by BG Tech including come Uniden, Radio Shack, Early Warning, and PNI units built a few years ago.
The issue is the frequency plan they use and the sweep and park rates.
The 9 band models park at 12.180 for 120ms every 240ms. The 2nd
harmonic of this is at the upper edge of K band.
The 10 model parks at 11.350 for 50ms every 350ms and causes Ka alerts as the 3rd harmonic is 34Ghz.
The 11 band model does not park unless you engage Spectre and or VG2. When you engage Spectre the unit parks for 60ms at 11.1 every 428ms.
This can cause Ka at 33.3Ghz and our unit detects Kafrom 33.2 to 36Ghz. When you engage VG2 on the 11 band unit, thefrequency parks at 10.950 for 35ms or more every 260ms. The 2nd harmonic of this is 21.9Ghz and falls into our low side image during our K band.
Our K band is 24.0 -24.275 with a low side image of 21.9-22.24 We use a fast scan during POP on and a slower scan during POP off.
When the unit is in POP on and running the fast scan it is eligible for POP, but if the unit sees a signal it will go to the slower scan to get a better look at it. During the slow scan, the POP% is around 50%.
As you can see if another radar detector was around that was left on during our test this could have affected the POP results we got as well.
Just thought I would share this information with you.
