Hey everybody so it is my understanding that having POP on will increase the sensitivity to instant on radar guns is this correct? my second question is does turning on the new junk-k fighter decrease the sensitivity? I want it the be the most sensitive as possible, would that be POP on and junk k fighter off? or does the junk k fighter use software that doesn't effect the sensitivity to actual radar guns? thanks
With most detectors it's been my understanding that enabling POP can actually decrease performance to IO as counterintuitive as that may sound. The exception may be the V1 as its enabled by default but I haven't specifically tested it.Quote:

A comment Mike Valentine made a long time that has proven correct is when triggering radar guns at point blank range or otherwise extremely close to an RD, it can "overwhelm" the circuitry with too strong a signal strength and cause the RD to not alert consistently.
We have also seen other examples that if a radar guns transmitting antenna is pointed directly at a receiving horn of an RD that the RD can actually get "cooked" and damaged as a result.
Interesting video, though. Thanks for posting it, I hadn't seen it before. Sitting on the side of the road doesn't exactly count as "risking" one's life. ;)

I agree with the risking life comment haha. What about this:
POP ON
K -121 Responded 100% at time intervals above 100ms
33.8 -112 80% at 67ms, 100% from 100 to 200ms, 20 to 80% from 300ms to 600ms, 100% above 700ms
34.3 -115 0% below 500ms, 50% from 500 to 600ms, 100% above 700ms.
34.7 -115 0% below 300ms, 50% from 300 to 600ms, 100% above 700ms
35.5 -113 0% below 300ms, 50% from 300 to 700ms, 100% above 800ms.
These times were based upon 10 tries at each interval of 100ms from 100ms up thru 1 sec.
POP OFF
K -121 Responded 100% above 200ms.
33.8 -112 Responded 100% above 600ms.
34.3 -115 Responded 100% above 700ms.
34.7 -115 Responded 100% above 400ms.
35.5 -113 Responded 100% above 400ms.
Unit would sometimes alert at bursts less than the above during POP OFF mode but not consistently enough.
POP attempts with POP ON. 10 random tries at intervals of 10 seconds or more
33.8
67ms 80%
100ms 100%
200ms 100%
300ms 70%
400ms 50%
500ms 20%
600ms 80%
700ms 100%
800ms 100%
900ms 100%
1 sec 100%
or this:
"I have not noticed a difference vs. 34.7 Ka by running with POP off, but K-band seems to be more consistent with POP on.
In POP mode, the V1 is sweeping 33.8 Ka and K band at 5 times the normal rate which gives it a better chance of seeing a weak signal (and in the case of 33.8.......verifying it) before it disappears. I think that at fringe detection range the signal is unstable with irradic peaks above the noise floor.......and so this increased sweep rate can improve detection range.
So I would say POP on should theoretically improve 33.8 Ka and K-Band range. Turning POP off would have a much smaller positive effect on 34.7 and 35.5.
I'd attach the document but the upload takes an error on this forum.......like everything else.http://www.radardetector.net/forums/...s/rolleyes.png

Check out Figure #6. That is the basic V1 LO Sweep scheme.
Figures 2 & 3 are normal sweep without POP activated and figures 4 & 5 show the sweep pattern with POP active. You will note the (5) mini sweeps for 33.8 and 24.15 (as well as an oversweep looking for LO harmonics) with POP active."
I would turn Pop off. Leaving it on gives lots of false alerts. At night I love pop corn.
Its been tested extensively using my unit on www.radardetectorfourm.orgQuote:

I dunno...from that video the only thing I took away was that if you have POP on, and it alerts, it is telling you that you have been busted.Quote:

Authors note: I am in no way holding out that I know what the heck I'm talkin' 'bout. I'm new, and a little knowledge is a dangerous thing. But still...I haven't seen any practical examples of how POP might actually facilitate a successful ticket avoidance. Coupled with (it's my understanding, I stand ready to be corrected) it's somewhat limited use by LEO in general, I don't see how the positives outweigh the negatives.
Ride safe,

what about what I noted in post #5 ?
This looks like M. B.'s lab data that was done years ago. The newer software of the V1 is in a different world. This data is good reading but of no use.......Quote:
