This was a GREAT Mike reply on POP algorithms and Cobra falsing in general. It doesn't explicitly say anything about Bel and range/sensitivity changes in POP mode, though it does state some of the other changes to Bel's filtering algorithm in POP mode.

Mike Valentine reply about the J alert. Notable quote:

The common method of reducing the number of false POP alarms used by our competition is to reduce the sensitivity to POP signals (and their Junk kin) while leaving longer-lasting (over half a second) signals unmolested. This method requires reducing POP-radar range to line-of-sight-only distances in order to give enough relief from detector-generated false alarms to be worthwhile. I wasn't satisfied with only line-of-sight range for POP radar reception, so we pushed for a better solution.

"By our competition" is vague, though I think he is referring to Belscort... I doubt he'd consider Whistler, PNI, Cobra, etc as anything but jokes ;-)

I don't get it...does it limit range? I'm not THAT literate with technology...

Short story, we don't know. We do know from Mike's post that POP ON will cause increased occurrence of falsing, and also locks out (rejects) some other frequencies within police radar range as common falses in POP mode.

We really don't know much more than that definitively. Though I am reading Mike Valentine's post as an allusion to Escort/Bel.

This would explain why another forum member mentioned that before he approached a KA instant on location, he would get a POP alert...
this would be a good warning!

HMM...to turn it on or not to turn it on...
