for more effectiveness, wrap the wire several times in (and around) the ferret core
instead of a wire like this: _____
wrap the wire like this: __O__
the O goes inside and around the ferret
Huh? Wrap the wire in/around a ferret? :shock:Originally Posted by ahmadr
One of these?

Is that ferret named ferrite??Originally Posted by kpatz
This is so funny. What a great ferret picture. Who the hell would mess with his core, or try to put a ferret choke on him? I wouldn't try to wrap anything in or around him! :shock:
I just don't think these type of ferrets are going to work for this project.

I took off from a stop light on wet pavement last night and got on it really hard (let the WRX STi spin all four for a while!). Got me the first false laser alert I've had in over a week. Then another. Then a strange one that was sorta delayed from the high tach reading. I think the (now newly named) Ferret Choke is working, but not quite enough. The delayed alert makes me think there is some sort of harmonic thing going on with the inductance that maybe overloads it or passes thru it. I'll study up on adding the capacitor and probably go for that next. I'll try to place it in my patch cord arrangement so it can still be removed without problem or damage.
Did you simply snap the "ferret" over the wire, or did you wrap the wire around it once or twice? The more times you can wrap the wire, the better.

I'm guessing no one ever found a permanent fix for this? I found this topic through a quick search.
I drive a 2007 Subaru WRX-STI also (same type as Original poster), and have been getting these false laser alerts on hard acceleration...
I pretty much narrowed it down last night. I went on a backroad in WV. It was dark out, so no sun light reflection. No houses around. Cruise control was off. And no other cars on the road at all.
I'm wondering if this could these falses could be a result of some sort of knock sensor? Maybe some sort of feedback as the engine pulls timing?
Laser falses caused by acceleration or honking your horn are due to electrical noise in your car's wiring. The very first thing to check is that the RJ-11 plug on the end of the power cord is crimped on well. Most Radio Shacks keep a RJ-11 crimper handy for quick fixes for customers. Be sure that the Smartcord is unplugged from the cigarette lighter socket or that the inline fuse is removed from the straight hardwire cord before using a crimper! If you are using a cigarette lighter power cord, the problem could be due to corrosion on the cigarette lighter contacts or poor electrical flow through the stamped together connections within the cigarette lighter. A hard wired power cord, wired to your car's fuse box, usually fixes this. If you still have problems then a snap-on choke or noise filter might help, but the ideal solution is to use an audio RC noise filter that consists of both a filtering choke and capacitor. They are cheap and you can even salvage one off of an old car stereo. It is the stuff which is inside the small black box on part of the stereo's power and ground wires. Even a cheap or salvaged RC noise filter will attenuate electrical noise by about 45dB and should completely solve the problem. If, after all of this, you still have a laser falsing problem which isn't caused by the sun or other IR sources, then the issue is the shield around the laser detection amplifier circuitry within the radar detector. That is a fairly easy fix too, but it is best to have the RD manufacturer fix that.Originally Posted by GHott
