This is an older side mic cobra. 1997. Do I need to go older than that? I bought this radio new. I used it for a number of years. then I stored it in the original box for close to ten years before I dragged it out and set it up in my p/u. Running it with a roof mounted Wilson 1000. Apparently the palomar 225 isn"t helping it any. I was talking to a local who is maybe a mile away and he said he could barely hear me.
