"L" Advanced Logic Mode Filtering?

I told you guys I wasn't Mike Valentine... and I am not employed by VR.

Now, my backup has arrived. :twisted: Let's Dance.

Hmm. About how long do these take to get a reading and are they at a frequency that's likely to be detected by my RX65? After JTW's tests of the X50, i'm just a tad concerned about the instant-on performance of my RX.

Also, correct me if i'm wrong on this, but none of the DSP of the Belscort units shouldn't be in effect if the unit is in highway mode, right?

Well, I believe I've heard of units like that before, but I think if anything it was an obscure feature, and I dont think any of the newer, current radar models have this (the closest thing is POP). Pretty much all of the units nowdays have the RF Hold or Standby that can be flipped on or off at will, or tied to the trigger.

I wouldn't be all too concerned just yet, maybe just a little bit

IMHO the verdict is still out on this. It has been suggested that the BEL and Escort sometimes overload at close range and won't alert at all. I don't remember where I heard this though. Actually I thought that I saw a post where Mike V told this to someone, but I can't find the post now? (If anyone knows where I saw this, let me know!!!)

I know in my own testing of the RX-65 with an MPH K-15 K-band radar unit at close range, I can quick-trigger the gun so fast that the RX-65 doesn't alert (and V1 alerts every time) But, this test might not be accurate. I've seen enough inconsistent behavior by the BEL at close range to make me think that the close-range testing is a problem and might not be accurate.

Radar units nowdays can acquire a speed vetry fast: just as fast or faster than they can be switched from standby to transmit and back to standby again.

I would say that the DSP is "on" all of the time as part of the way the unit works, and the detector just changes the algorithm it uses to evaluate the signal in the different modes. But I doubt that the DSP is necessarily causing a slower reaction time, if indeed there IS a problem with this in the BEL.

Thanks professor Jim. The reason I asked about the DSP wasn't so much that I was concerned with the delay, as that I was wondering if the signal strength was such that it was ignoring it. Might you mind trying a few quick trigger tests with your K-15 at a little longer range if you have some spare time one day? Maybe have your wife drive the car with the RX in at towards you and quick trigger the radar? When you say that the RX65 didn't alert, did it never alert or was it an intermittant thing?

I assume the RX is running some frequencies (33.800) as priorities since it seems to do an excelent job of POP detection, but seems to fall behind with fast signals from other areas of the bands. I know it can handle POP pretty well, as I loaned it to a friend to use on a two day trip once. He was headed to Indiana from Illinois. Came up on a big hill with one car a decent way in front of him. The officer POP'ed the car ahead of him before my friend crested the hill, and saved said friend from what would have been one nasty ticket (I won't even tell the speed, i'll just say he was 'rockin')

While it's not something that's going to cause a great loss of sleep for me, I do just like to know what the limitations of my equipment is before i'm informed of them by an officer. I drive with the RX65 all the time, but I still drive as if I didn't have it. I know my eyes are the best weapon of all, and besides, if i'm pushing a speed, I should be looking farther down the road anyways!

The above statement my friends is the key to an enjoyable ticket free driving.

I just might have to do that

It was intermittant...
I actually did a video, but there was a lot wrong with it: it ended up being 7 minutes long, the lighting was bad, and the RX-65 was too quiet. But, if you want to see a short clip, I uploaded it here:

I planned to re-do it, but after hearing about "overloading at close range" thing with the Belscorts, I figured the setup wasn't good for testing anyway...
