Any updates by the owners of the M4 Rev. 2.9? Does the new antenna allow for better laser detection? Better range?

I have a 1994 Toyota seq. which my wife drives. I have also have 2005 Toyota Seq. which I mainly drive. I have had all the top detectors since the orginal escort. I still have an Escort DSP and CM passport in other cars. I tired the the latest V1 and returned it after two weeks. It was going off all the time. With so much noise I can go with out the arrows. Everytime a Mercedes with the blue white lights drove by theLaser would go off. I learned this from before that the wider range of the RD has many signals that it picks up that are worthless. I bought another RX65 which we had in our other 2004 Seq. It was version 2.9. I was upset when I got it but tried it. It is great. The second day I received a laser warning with all the family in the truck from over 3/4 of a mile when the LEO hit the car in front of me. I was shocked. My wife said wow that works well. I thought it was because of us being on hill and the far distance he has hitting the car. That is the longest I have ever got Laser reading on any dector ever. I was pleased. Have not had another alert since. So no falsing like the V1. I do have it low mounted about three inches off the hood. The unit seems to be about the same as our RX65 version 4.5 on all other radar ranges maybe a 200 feet better. I have had some good Ka range on two LEO's with this unit. I use motion doors to test the range that I know exactly where it sets off my other detectors. However, I have it on POP and not one false in two months. The main thing I can tell it has better sheilding. My GSM cell phones will not cause an alert like on our version 4.5. That is huge for me since I use a GSM phone both a Nokia and Motorola alot while driving. I have X off, SWS on, POP on, Laser On, K on and KA USA on. I love the RD. The perfect RD however is still not out. I wish it had a city mode for K. We live in a new area and every motion door uses k. I get alot of 1 and a rare 2 reading on the RD while driving. Wish the software would show these alerts on the visual but not with sound. This would stop it 95% while driving in the city. When on the Highway all three of the top dectectors work very well. I have heard on new antenna is coming on the x50. Anyone see their FCC filing? I will let you my experience going forward. The Rx65 remains top notch and just got better.

i got hit twice tonight mine is the m4 2.9 first hit was ka picked him up 1.7 miles away thier were a couple small curves in the road it wasnt straight second was ka again this time i only got .7 when i first picked him up i came around a curve and it started at ka2 from when i picked him up and where we met was .7 miles but he was coming at me speed limit was 60 so not really sure how far he was when i picked him up from how far his headlight looked it deafinatly looked like over a mile the first time the cop was sitting still a whlie back i had another ka it was 1.2 miles on that one

I have the M4 2.9 purchased 29 days ago from RR. I have noted in several posts that I have grave concerns about K-band performance. Over hills and around curves I am seeing Passport 7500 level performance, which is nothing to write home about.

Two days ago on the way home, I arrived in a town village and made a turn onto the main drag traveling approx 300ft around a slight curve. At this point 700ft ahead I noticed about a dozen emergency vehicles at a fire scene, with a cruiser parked at a 45deg angle blocking both lanes with the front of the cruiser closest to me, and with several hundred feet of open space in front of it before any buildings. I continued to travel forward looking to turn around in a parking lot, when at 500ft the RX65 alerted K-band. I had to travel another 100ft or so, and the signal level climbed so the cruiser was obviously sitting their with constant on. I was flabbergasted, the original Escort CM would have ripped itself off the visor, wrapped it's power cord around my neck and poked me in the eyes with it's toggle switch to alert me as soon as I turned onto the main drag.

Yesterday on a flat and straight roadway I recv'd a momentary K-band alert and them seconds later another, so instant on sampling was underway. I finally spotted the cruiser trailing behind a small box truck and playing peek-a-boo. Distance to closing at 60mph was a half-mile, so figure about 1 mile warning. That's Ok considering he was using the box truck for cover.

But I am starting to get a bad feeling that the new antenna setup has a very narrow beamwidth on K-band. This would lead to less falsing in cities from door openers, and on interstates fewer problems with other noisy detectors. It would also allow you to have increased sensitivty straight forward, because you are looking at less of the landscape, which will lower your overall background noise level.

So one thing all the M4 owners should keep an eye on is straight ahead versus curve/hill sensitivity on K-band. I am gonna guess that even a slight curve is going to reduce K-band distance substantially. Those M4 owners who travel interstates daily are probably going to have the more easily verfied data, as they can watch what effect slight roadbed changes have.

And it may turn out that the new X50 antenna is being carried over from the M4, makes economic sense.

yea ive been hit by k band a couple of times it was the sheriff coming at me doing at least 70 mph with a descent size median and slight curves on i75 and i only get about .7 of a mile but when you figuire in the moving part its probaly over a mile definatly get more distance from ka then k which is ok because the state troopers use ka here and they will write you a ticket before the sheriff will they normally give you a break

I had one K concern, it was instant on, but have been happy so far. I will watch.

Good post microbb

It would be interesting to have the original RX65 and the new M4 RX65 for side-by-side comparison (preferably one at a time, of course).
