I just got mine today, after messing with it it dose look like a hex screw for the antenna. Once I have a driver that can remove it I can update.
One thing that does bother me is the backlight stays on when you have signal, the backlight will not shut off at all.
But the rest of the radio so far is a solid radio, Front end programing is easy but I do have a cable that will be here tomorrow so I can get it all set up with the fine touchs.
Anything you want to know ask and ill try to answer.
