I have a strong feeling the Ka band on my 8500 X50 rev 5 is not working, because it never goes off. I've had this detector since September 2005, and I cannot recall a single hit on Ka band. Has anyone else experienced this?
POP, Laser, K, and X have all gone off. I drove by an accident the other day where six CHP were gathered, and the detector was silent. I find it hard to believe not one of them had their radar unit on. Last night I got on the freeway and I noticed I was 2 cars behind a CHP ... I followed him for 10 miles just to see if my detector would get a Ka hit and it never did (CHP use Ka, K, and Laser).
I emailed Escort, and they replied that their "filters are the best in the business, the unit runs a diagnostic every 8-10 minutes," etc. etc.). I've had no "self cals" or "service required" on this one, and yes, Ka is turned on. I've even reset the unit a couple of times to be sure.
I've had X50's before (this is literally my 5th since June 2004) and Ka always went off and in fact saved me from more than a few tickets. I'm starting to lose trust in this one. Thanks.
