I hate sending my radio in for repair. I noticed that the SMA loosened on my original unit. So, someone suggested that I purchase a span wrench to tighten the SMA. After buying this wrench, I am having second thoughts. Reportedly, there is another portion of the SMA assembly inside the radio that might get screwed up. I fried the circuit board of my AR1000 with a soldering iron. I think I'm going to send this one in to Uniden and pay the money for my peace of mind.
