I used one back in the 1970's during the 55mph days.
Then, it sat on the shelf in the garage for years, so I put in the truck a few years ago when I got the RV. I had to chuckle, because when I turned it on, it was like a step back in time....the same most useless drivel being talked about....truckers complaining about the slow cages, and not making enough money. And then I also go to be ( apparently ) entertained by some fool that keyed his mic so all could hear his favorite country western song. Yep....just like the '70s' Smokey and the Bandit all over again. Ugh..... I turned it off, and removed it again when I got home. It's back on the shelf in the garage.
