That was indeed a nasty spot! It would appear that he got bored shooting radar and went looking for his next victim. I suppose he could have been on a call about that semi but it seems unlikely.

Something seems to be wrong with your ramp up?

That’s what I thought at first too, but here’s what I’m thinking now. One the first pass, he let go of the trigger as I approached (no traffic behind me). On the second, it ramped down pretty normally until he turned out, causing it to alert back up again (his front antenna was now shooting me in the back). Then he turned radar off shortly after. Overall tho, it wasn’t really a confidence inspiring detection like my first one was, even though it had pretty odd ramp up too.

I know that area very well. The good news is that was C/O from his rear antenna - the ramp tells the story. While the DFR series' ramp up/down is nowhere near as good as the R series, it's still accurate and textured enough that we can solve this puzzle by rewatching the video a few times.

The driver of the truck he stopped probably figured, as you and others just have, that he was targeting cars coming over the crest. Nope; he was monitoring speeds of vehicles that had passed him. And the delay from the time the truck passed him to when he turned around, was very likely due to the fact that the LEO was happy to wait for a break in traffic to safely turn around; easy enough to chase down a big rig.

The AR Highway police will stop cars and pickups for speeding, but their main role is to focus on Semis, and in this case he didn't like that truck's speed after he'd passed.

IMO, the DFR7 would have sniffed out I/O from a mile or two further back if it the LEO was aiming at vehicles going over that crest. But it made for some adrenaline pumping haha, and a swing around for another pass I see! I see RD testing in your future. :D

This does inspire some more confidence in the DFR7. I thought my anchor saved me! The thing that made me think it was his front antenna was the fact that I never recieved another hit after I passed. On the second pass, it ramped down until he turned around with his front antenna aimed at me. Also, if he was running his rear antenna, wouldn't people just slow down on visual? If I were him, I would try to hit cars over the crest.

Yeah, if it were me, I'd be targeting vehicles coming over that crest. It's rather counter-intuitive what he was doing.

But in your two encounters, the intensity of the ramp wasn't the urgent kind that you get with a face-full of close direct-path I/O. Unless of course your unit is really sick and detection range is horrid because of it, and further encounters ought to let you know that. (speaking of that, what was your detector doing when you drove back to do a re-approach? Was it a more urgent alert/ramp up coming back the other way? Or did he have it shut off then?

Anyway, my thinking is that had you been the target coming over that crest, the initial alert/ramp up would have been immediately full-tilt the moment you had line of sight with his vehicle. But it wasn't. We only hear that full-tilt alert at the point where you got a strong reflection from vehicles literally 'behind' the LEO' (i.e. he's facing you - parked dangerously if you ask me; he has to make a full U-turn in front of approaching traffic, what a bozo). And re the slightly different ramp between your run 1&2, you were in different lanes, so the reflections were different, so maybe the DFR7 held onto it a bit longer for run 2.

He ought to be positioned so he can pull out in a safer manner when he picks his victim. He obviously wants to see the drivers faces as traffic passes for whatever reason, maybe his logic is, "Well, you should have seen me when you passed, and still decided to exceed the speed limit". He probably shows little mercy to drivers who do it.

I've only had one other encounter with this unit. Ramp up is a bit strange here too: ASP CO Ka 34.66 - Streamable

On the way back, completely silent. Basically, all the alerts I had in this encounter are included in the video.

I really hope my unit is working properly. Got it from buydig.com using Vortex's discount code.

That's another LEO front antenna encounter; he was targeting cars merging up ahead of him from I-630 onto I-430. Watching that video I hear a much stronger ramp near the end of the encounter (albeit a tad few seconds delayed actually, not the most accurate ramp up for sure) when you got strong reflection off the overpass and sign. I'm really not a fan of the DFR ramp up/down, but the general sensitivity of the series is really very good despite the less-than-ideal ramp behavior. The trick to working it out is listening for the strongest/most urgent ramp, allowing some wiggle room for lag/inaccuracy and apply that to surrounding obstacles. But there's no mistaking when you get a face-full of signal; it should be full-on urgent strength, and none of your encounters have had that yet.

I've got both a Stalker ATR 34.7 and Decatur Genesis II 35.5 if you want to meet up sometime today (or another day) to test your unit. Feel free to PM me any time.

And, @ARkaband , I've got a Decatur Scout K band as well. I've tested with. @hiddencam several times and always had a blast. I'd love to do another get together any time.

Your ramp-up's from both videos seem to be on par with what I would regularly see with my DFR6. Honestly, the ramp-up of my unit was my only real complaint. I found it much easier to follow the strength meter than listen to the ramp-up. Obviously, that's not ideal because it means taking your eyes off the road.

@NorEaster18's first video shows what a face-full of signal looks like.
