I lived in Arizona for a while and had a Henry SS750 that ran more than a KW out on 40 and 80. Whenever I used it on 40m and a 90's Cadillac was within eyesight it would die. They always restarted but would have to pull over on the interstate. I had to be careful to scan ahead and behind and not transmit if I could see one. It also caused quite a traffic stir if it rained while I was transmitting. Big fire on the Hustler resonators. Larry Pace replaced every one that smoked and there were several. That Henry was a hell of a mobile amp!
