    Default Hello!

    Hi everyone. I found this forum today and it looks like a ton of great information and a place to share experiences and stories. I'm actually trying to decide between a V1 and 9500xi (leaning towards V1 for better range + arrows).

    Info about me:

    I'm a radar technician for Stalker Radar. I mainly do radar repairs (all units, including the Spectre RDD), phone support, certifications, and officer and service center training. I don't get to mess with the Lidar much but they're definitely fun to play with, especially the new LR.

    Glad to be with you guys and hopefully get a decent radar detector soon!

    Welcome to the forum! I'm sure you will get lots of questions. Is it still possible to get
    an ATR that transmits on 34.2 and/or 35.2 GHz?

    All of the gunn source assemblies we have are 34.7GHz. From what I recall there were only a few that were off that frequency and should be pretty rare. I haven't seen anything but 34.7GHz ATR units in the 3 years I've been here. Did radar detectors have a problem picking those particular models up?

    Here's another question that only an insider might be able to answer. Evidently, at some point there was a version of the Stalker ATR that was a "frequency hopper" or "spread spectrum".

    There's a reference to it on CopRadar.com:

    http://copradar.com/preview/chapt11/ch11d1.html


    And here's an old post from rec.autos.driving back in 1992 that referenced the unit:

    |> at a ham newsletter (sorry, but I didn't write down the name). One
    |> small article concerned a radar gun manufacturer who was seeking FCC
    |> permission to develop (and presumably sell) a spread-spectrum radar
    |> gun.
    |>

    Sounds like The Stalker, made by Applied Concepts, Richardson, TX. They
    had to get special FCC dispensation to go multi-frequency up in the
    Ka wideband. Been around a little over a year here, but more in
    beta-testing than in real use - partly because of price. Last we
    knew, the frequency was set/changed manually - but that was a year or
    so ago and A.C. *was* saying that an auto-hop rig was in the works.
    Not saying what change algorithm they were planning...
    What's the real story on this gun? How did the "hopping" work: did it hop between several freqs between 34.2 and 35.2, or between specific frequencies? Did it simply have a different freq every time you transmit, or did it actually hop during transmission? Did they sell a lot of units? Why did the model get scrapped?

    I'm sure you probably don't have the answer since you weren't there back around 1992 But if you could talk to some of the old-timers and get back to us, that would be great!

    I haven't heard of anything as far as auto-hopping. I had our senior tech look at your post (he's been here at least 15 years) but doesn't recall anything like that. I could mention it to one of the original engineers here but I think I know the answer. It was probably dumped because I'd imagine anything we or anyone would do in the Ka spectrum a detector could be made for it. So, it would be waste of money in the end I would imagine. Design radar "a". Design radar detector for radar "a". Design radar "b". Design detector for radar "b", etc.

    I did play with throwing the frequency off one of our DSR microwaves but my little Whistler 1778 detected it anyway, so I kind of gave up on the idea of being able to run radar and a radar detector at the same time.

    If a BEL radar detector was operated in Accusweep or USA mode, which blocked out parts of Ka band outside of 33.8, 34.7, or 35.5 GHz (plus/minus 100 MHz) yes it would miss that particular ATR. I was operating my BEL 985 in Accusweep mode and it totally missed the ATR, while my V1 picked it up. Once I turned Accusweep off it did pick up the ATR.
