I have been away from the scanning community for a long time. I last owned a 536. Loved the unit even with all its short comings. Any way, I recently scored what looks like an almost brand new unit for 25 bucks. I do think the guy had any clue as to what he had because he said it was 40 channel. I laughed hard on the inside. It did not have any power cables. Can someone point me to where I can get some for house and car?
