Bands, Haha, I did a search and found it was from 1985. Back in 1985 I would be willing to bet it was still X Band, maybe, but I doubt it K band.
Back then the radar unit used to hang outside the patrol car so it didn't cook the operator.
So in this search I found a great article about how people felt about Radar and Detectors in 1985 as well as this ad.. http://www.nytimes.com/1985/08/24/business/the-boom-in-radar-detectors.html
