Ok please don't make fun of me. I have been using scanners since 1970. Crystals were so easy. I am putting together an unmarked car for a small agency that I work with. I want to add a scanner with an external antenna. I have limited space due to 2 Motorola radio heads. I have nothing but headaches attempting to program my bcd396t (I think that's my portable number). I am considering purchasing a home patrol. Does anyone have any experience with it mounted in a vehicle with external antenna? Does the dc cable work ok? Thanks
