sorry, but after four or five purshases from Airtronics,, and dealing with there customer sevice,,(and I'm talking from 1982-1985 to the recent) Iwont buy from them . I hope youfolks don't have a problem with your radios. I knowthat most of you that post here are probably working for Airtronics. Let it be known, I don't work for anyone in the modeling biz. I'm just posting so the other folk out there know that before you buy a radio, look it up online and go to the customer service.
