This document was originally obtained from the Pennsylvania State Police Department’s Web site, which surprise, is no longer available or listed on their site. I have archived it to PDF for others to use. This document states that in September 2003, the Pennsylvania State Police Department temporarily suspended the use of all Genesis Handheld Stationary (GHS) radar units in in its 2003 and 2004 model Crown Victoria police cruisers after learning that numbers were being displayed on the units’ readouts that did not correspond to measuring a vehicle’s speed.

Tests conducted by State Police, by an independent, certified facility, and by the manufacturer determined that the isolated readings were caused by frequency noise produced by the alternators in the 2003 and 2004 model Crown Victoria cruisers. The alternators in those vehicles produce a different frequency noise than alternators in the Department’s other vehicles.

Funny thing is that this original testing report was never released to the public, Decatur Electronics offered free battery packs to correct the problem (don’t need to plug in to cigarette lighter which was causing RF) and the Pennsylvania State Police, for unknown reasons (really they didn’t want the public to contend the 26 million/year they were making), declined to have the battery packs installed FOR FREE and continued to use the faulty radar guns.
