    So I bought one of these today hoping to use it for my own testing.

    Brain fart, I knew that. What I should have asked is if it is FM capable.

    According to this thread www.rdforum.org: Filtering FMCW

    “There's only two police radar guns that I know of that also use FMCW, and that's the MPH Ranger EZ and Stalker DSR 2X. The Ranger uses it to help you identify how far away the target vehicle is and the Stalker uses it to give you an OMG Panic! alarm when someone is rapidly closing in on your rear while you're parked on the side of the road. “

    I think you misunderstood what he was saying. We ran the R3 on 1.40 with MRCD detection turned off and later with it turned on, just to see if it made any difference with the Falcon HR, which is only low power, vertically polarized K. Results go up tomorrow, but no, not shocking differences.

    PS Turn K Filter to off on any detector only if you want to throw the thing out the window in short order.

    I got an idea, let's get back on topic. Starting with this. what do you think this guy could be doing. He rolled in from the neighborhood across the street then turned my direction

    be careful i clipped out audio until the second R3 got an alert to try and avoid the copyright issue

    How in the actual hell do you know where that is.

    I’m guessing this was just an uncommon thing or is off axis really that bad?

    If that’s over in Caldwell, I’m not familiar with that area. The only legit 33.8 I’ve personally run into is in Liberty Hill, far northwest Austin, one of their local PD cruisers (an Explorer, if I recall correctly).

    I'm starting to think my R3 may be defective. Earlier today while driving the back roads with hills I had an encounter with a LEO. While making my way over there hill the R3 instantly went off with 34.7. I was going slightly over the limit and would have had 5 seconds to slow down. Fortunately for me the LEO flashed his lights while I slowed down. He never turned around.

    I'm not completely sure but I think the LEO was running c/o. He was driving north going up the hill (4° slope gradient) I was driving south.

    Our 2nd R3 arrived so I'll be testing it out over the next few days and hopefully have a fair comparison of how each unit performs against each other.

    Also, I'm in Tennessee (near Nashville) would I see any performance difference in running Ka wide, narrow, or seg 2/5/8?

    Of course they all have hand held remotes. They can clock you in milleseconds.

    I am from TN as well (Memphis). TSP (state trooper, ford explorer, 34.7 KA) run instant on in my area on interstates and loops. When I tested the R3 on Ka 2/5/8 segmentation, it gave me much more time. When I run KA wide, the instant on is exactly as you described.

    Side note from some testing this morning: I run waze simultaneously, and I knew the LEO was there a few minutes ahead of time. It allowed me to test Narrow v Wide. I will definitely be running Narrow only in my area as it gives me the buffer. I did a couple runs back and forth (there was a lot of traffic so it wasn't obvious) between Narrow / Wide.

    For those of you in middle Tennessee who are interested, I have a Stalker II SDR and would love to do a shootout in the next several weeks. I run a R3 and a V1.
