This past weekend I decided to see whether the "cheap Cobras setting off other detectors" thing was accurate...
So w/my family's mini-van parked next to my car, I plugged their $30 Cobra ESD7000 in while my Whistler 1793SE was running. With both vehicles parked side-by-side, and both detectors pointing straight ahead, both detectors remained silent. Then I rotated the Cobra... and suddenly my Whistler comes to life. When the Cobra was turned completely in the direction of my Whistler (so at about 45 degrees off a direct face-to-face setup), the Whistler reported full strength K-band. As I turned the Cobra toward straight ahead again, the signal strength dropped and then went silent.
Next I'll have to test the range at which I can pick up the Cobra head on, but I'm figuring it will only be a couple of car lengths at most. Hopefully that'll be good enough though for testing where good mounting locations are and how things like the tint strip affect detected strength (if at all).
