Outer Rim - Hiding from 35.5 I/O
As for the ramp, I have only seen it on what I suspect was a Ka IO in the field. I haven't seen it on the bench, but I may not have driven it high enough to see it. I only drove it to just solid tone.
Without overdriving the detector, hit it with Ka signal strength that simulates being in or near the kill zone and see how many seconds it takes to go to six bars.

The issue is more that you have to drop anchor all the time because you don't know if you just got hit point blank or if you're only picking up distant Ka.

It's not about berating, and I love the technical bits! But this is a very simple matter to me.

It's that there are conflicting testing results. That's not s trigger for a warning or this is how it is, rather a call for more testing!

You're a knowledgeable person, do you have any thoughts as to why there are conflicting testing results with lab vs. real world?

Not in a manner to defend the V1G2, but to learn about such things! that is unless you disagree with the results I posted. There could be very legitimate reasons for why you see one thing versus another!

it seemed that you personally drew heavy conclusions from your testing results, and so could others. I'm not trying to be rude, but I am saying that maybe there's more info out there to also consider!
Like I said, when you pull the trigger, the radar transmits immediately. The reading doesn't appear until ~1 sec later if the speed is repeatable within a tolerance. To the operator, it would appear that the 1sec V1G2 delay is matched to the reading of the radar. When in actuality, if the V1G2 responded like the V1G1, it would alert 1 sec before the readout of speed.

I'll try it, but I trust you. I can understand how that occurs. I know there was an RD years ago that had the same issue when I tested it in K band(before Ka). Ignoring the K filter, you basically have to bypass your signal integration and just 'or' in the detection on the pre integration filter.

BTW, I usually at least lift if not brake for all Ka..... I used to do that with K...... but I understand the dilemma

Read the OP and explain to me how that doesn't apply to him as well?

It's interesting to disregard those results which are posted here by the testers. I am simply referencing it.
What? It does, at least until I see evidence, but that doesn't change the fact that the OP is right about the delay, we know he's right from other data points and sources.

Whether or not the delay matters in a real word situation could be up for debate however.

Obeer, thank you for the acknowledgement first, before the rest.

So it sounds like more real world testing is ahead of us, hopefully! Glad I think we all came to that same conclusion.

Op, I do find your testing very interesting and would love to see more! Videos are fun too but I understand because they are a burden to put together sometimes! Thanks for your time, and I hope you consider what I shared as well!

Many of us here own radar guns, even multiple radar guns and Lidar guns, myself included. We have a pretty good idea of how they work and experience actually using them.

Also, you may have noticed that some of us have tags next to our names like beginner intermediate and advanced. That's not just for post count but for different areas of the forum.

As far as the issues with the V1G2, there are two basic issues that are affecting what you see. One is the delay on K band as it's filtering. The second is the lazy ramp. They compound each other on K but if you've noticed, even though Ka band alerts immediately the lazy ramp is actually worse on Ka band than on K band.

The lazy ramp issue is that it takes a while to ramp up to a full alert urgency when presented with a strong signal. It's a problem against I/O and if you do some searching around here you should find mention of it.

VR is aware of both issues and is working on them.

Own or have access to through other members, which is what makes this place so awesome!

No problem, I didn't take it the wrong way.
When I talked to the tech, it seemed that he only knew of the ramp. He thought the delay was the ramp. The POP did concern me though as I have not seen it mentioned anywhere else. Do you or someone else have a K POP? I'm only simulating what I understand their waveform does. I may be wrong, but probably not, as the V1G1 responds and the Ka on both Gen1 & 2 respond.

As for the ramp, I have only seen it on what I suspect was a Ka IO in the field. I haven't seen it on the bench, but I may not have driven it high enough to see it. I only drove it to just solid tone.
The likelihood of facing POP is small (no totally zero, but small).


Even in MPH Industries manuals, they say not to use POP since it isn't entirely accurate.

So my (collecting dust) V1G1 handles this properly? I was unaware- until looking through this thread- my V1G2 is (currently) deficient in this area.

Lab testing if done correctly, will show the theoretical performance of the unit. It will only degrade in the field.

So true. Do you have access to a 35 GHZ spectrum analyzer? If so, could you, by chance, measure the forward, rearward, and side emissions of a G2 and post the analysis? There is a debate here about whether the G2 emits enough RF and relevant frequencies to impact another detector.

No, unfortunate;y my specan only goes up to 22GHz. I have synthesizers that go to 26 directly and up to 40 with a doubler.

I have been running my G2 right next to my G1 and there is no pickup by either as far as I know. Running an old G1(90's) against my old escort(80's) showed definite coupling that was unique to 2 detectors seeing each other.

VR claims that there is very, very low emission and I would tend to agree that it would be very hard with an LNA as the first component to have significant leakage. There may be some leakage right at the case, but by the time your 3 ft away, it should be undetectable.

I ran my latest Rev G1 and my latest Rev G2 side by side for 2,400 miles


but was unable to detect any cross-talk or degradation in detection performance. Thus **suggests** to me that whatever the emissions are, they are not material to performance. (Suggesting that side by side performance testing is doable). However, there are some that **believe** that the emissions from the current generation of high end detectors **might** impact performance. So far, I'm not finding any evidence that the G2's emissions are material to RD performance. I'm not saying it can't. I'm just saying that so far, I'm not seeing it.

Obviously, a side by side testing challenges some "conventional" wisdom. But then again, so did theories that the "world was round" and that the "earth revolved around the sun". Now my test was just one test. It would be interesting to see more - especially with the latest generation of high end, low emission detectors.

In the real world I picked up Ka I/O shots slightly off axis at 5km's. Then I was getting his front antenna (facing away from me) at 2 km's.
That's good enough for me.

Yes, Ka is awesome! It is as fast as the old Gen1, but much more sensitive. I'm picking up Ka IOa over a mile away through dense woods. It is almost so far I want to forget about it!
I can't wait for them to fix K to get back to Ka's level of performance. Just be careful before that...

Totally agree, ka 33.8 I/O is amazing, had a save around a curve at 1.2 miles over the weekend. But tonight I ran into k band I/O, watched the rabbit in front of me save me and eat the ticket instead of the V1G2 doing the saving.... I miss my V1G1

I run with k verifier off at all times but still believe I’ll be burned on k band before ka
