I like to smoke cigars when I cruise, and I drive gravel roads up in the country. Now that I have a full rack mount mobile setup in the car, instead of just a CB and a 2m/70cm rig, I would really like to ask the question about how much of a threat these things are to all of my equipment that I bring along. Currently my setup has my Yaesu 450d big rig in the Gator case for a good quality mobile HF unit. That and currently I've switched to my Kenwood Kenwood v71a for 2m/70cm because of its dual monitor ability. I don't worry about my Cobra 29LTD CB radio, stupid simple and road proven (and most replaceable if something goes wrong with it) but the other two units are far more expensive and higher end. With fans on them for cooling, no less. Are these radios at high risk of damage from cigar smoke and dust? To what extent are such Amateur rigs built for the rigors of the road? Are they built for nice clean new cars, or for full on semi truck or rugged small truck use and abuse? Should I not smoke in the car, should I be more concerned with sealing the car against dust? Or am I worrying about nothing? Thanks in advance.
