OK, I was given a new cobra 18 WX ST for my birthday. Is this a good one? It has 3 weather channels, sound tracker, and instant chnl. 9. It seems nice. I also got a 82" stainless ant. I will be running it for a trail unit in Colorado, and Utah mostly. What type of upgrades should I do to this thing? Any info would be helpful. Like I said I am an idiot when it comes to CB`s.
