You guys know your stuff so i hope you can shed some light on this for me. I just bought a 955 after having a 940 for a year and a half. The 955 seems like a crapra compared to my 940. I work right next to my local police dept so my RD gets a good test everyday. (They run constant on Ka and K). My 940 seemed like it would alert sooner coming up to work. Also once it got a Ka alert it would hold the alert and ramp up the closer i got to the police station. The 955 gives me the Ka alert with one bar then goes away, then come back again with one bar even though im right on top of the radar source. Even tho it worked fine with the usual false X band spots aound my house I returned it to CC and got another figuring i got a bad one. Well no difference with the next one. I passed a trooper on the highway with this one. They sit in the medians with constant on Ka. The 955 alerted Ka with one bar AFTER i saw the trooper. His car was pointing right at me. It held the Ka alert at one bar until i got right up on him then it went back to Highway. never ramped up. He was sitting there on the phone so i know it wasnt instant on. Was frustrated after that so i went back home and got the 940 and drove by the same spot. 940 worked fine. alereted me almost a mile in advance and ramped up as i got closer to him. so i brought the 955 back to CC again and got another one. Try it one more time. Any ideas from anyone? I'm sure the 955 has newer firmware than the 940. The 955 has 6.3. i checked it. POP, SWS off. I run it in highway mode all the time. Is this normal with the new firmware? Did i get two bad RDs? Just got the third so i havent tested it out yet.
