A quick follow-up test, based on some questions in the main R7 spectre testing thread.

I tried disabling X/K/Ka band on the R7 altogether and the Spectre went totally silent.

K band on, X/Ka off and the Spectre alerts.

Ka on, X/K off, Ka 2/5/6/8 and the Spectre alerts.

Only Ka segment 5 on, the Spectre alerts.

So it looks like if there is any radar detection going on in the first place, the LO is on and the Spectre can pick it up.

I wonder what the results would be for various NetRadar units in the same test. I would imagine the results would be somewhat similar, but that is just a guess.

For states where radar detection is illegal this is where discreet profiles would rock - have one profile with it all turned off.... Then you can claim it is for Compass/Speed notification as well as red light camera notifications etc.... Effectively turn it into a glorified dash ornament with 3 clicks of the mute button or something then it could be done with a remote mute button.

My Netradar is about the same as my R3 with the Spectre III. Because it is a remote the location where it is installed could change results a little +/- depending on height the Spectre is mounted. Typically the more in line they are the better the detection.

Could tests be run with any or all of the R's with MRCD turned on and off. I don't have a Spectre but maybe going back to an older firmware without the MRCD option on the R1/3 to see if adding that affected stealth.

Yesterday I went to go finally test multiple copies of the R7 against both the Spectre III and Spectre Elite.
Yesterday I went to go finally test multiple copies of the R7 against both the Spectre III and Spectre Elite. Without further ado, here is the complete test results:


As you can see, the results are surprisingly variable. Depending on which detector and Spectre was used, things would be totally stealth, I'd get an alert only when passing, I could get an alert maybe 100 feet away, or in a few rare instances, I could get alerts several hundred feet away.

I'm going to work on updated R1/R3 testing next as well as post up some DFR7/DFR9 testing. With the other Uniden detectors, I also saw somewhat variable results.

The R7 is stealthier than the V1 and Max360c I ran, but I wouldn't call it completely stealth.

Finally a big thank you for @C2S for meeting up with me to conduct the test, to @Rossm812, @JPavilion, and @riseboi for loaning me their retail R7's, @Randy at Radenso for sending over the Spectre Elite, and Uniden for sending me the R7 beta I've been testing with! :)

My R7 has a serial number of 330. So I must light up like a beacon in a starless night :(

I read the other posts that you showed me. What if Uniden coated the chips and the entire mother board in a substance that kills RF? This way nothing will be leaked, but the R7 can still receive RF input.

Does anyone have a fix to their leaky R7 yet (maybe better shielding)? Their documentation still claims undetectable to Spectre I and IV but these videos clearly show it can be detected.

I think at this point you have to buy your own Spectre and see if the R7 you got is stealth or not.

Great video Vortex and thanks. I emailed Uniden about their stealthy claim and several internet tests showing it to be false. Hopefully, they will explain the basis for their claim. Maybe we should all do the same to show them how important it is to their market.

When i was more active 10 years ago, LO leakage was prevented using a horn filter of a specific length and diameter. The casing also had to be able to prevent leakage. My guess is that Redline is invisible because of the magnesium casing and I've seen pictures of their internal horn design. What material is the R7 casing? Assuming that the design is similar in the R7 and the shape of the narrow dispersion cone exposed in the R3, i'm guessing that the leakage is coming through the front somehow.

As i reconsider a complete replacement of my system, I was considering getting this detector but can't in its current state. Hopefully, they have some fix that is software based instead of a hardware replacement.

The magnesium case has zero impact on the RD’s stealthiness unfortunately; it would be great if it were that easy, but most of the emissions come out of the horn anyway, and the Redline casing isn’t magnesium anymore. They switched to plastic. Read Escorts patent on the M3 design, it’s not that simple of a feat. IMHO all the “stealthy” detectors besides the M3s are only less detectable because the Spectre doesn’t look for the main frequencies they emit. If Stalker ever decides to update the Spectre it’ll be game over for all those claims. That’s why the box of the R7 only says Spectre Elite immunity.

That would be a very viable idea.

I got to thinking about this a little, as I have a trip coming up through VA. I'm a radio guy, and use ferrite chokes on everything.

@Vortex Could you try a little experiment? Can you put a ferrite choke on the power lead close as possible to the R7, and see if leakage is attenuated any?

Sorry, I don’t have my Spectre on hand at the moment. @PY004 has it and did a bunch of testing. I’m sure he’ll post up his results once he’s a little less busy with forum duties.

If someone else has some detectors, a camera, and the desire and initiative to do more testing, I’d be happy to help provide some testing gear.

The LO leakage is through the antenna not the power cord, so a ferrite choke will not help. Low noise amplifiers (LNAs) are used in the RF front end to minimize LO leakage from the antenna. That is why the M3s have Spectre immunity. The Radenso Pro M also uses LNAs IIRC.

It couldn't hurt to try it. Sometimes RF radiates on leads...that act like antennas. ;)
