I have been a Technician at a casino for 20+years. I set up machines from scratch using mostly Linux systems and also maintain and repair electronics to the board level. And YET-- Have never been so frustrated in an electronic device in my life. Strange menus and sub categories abound. And that seems just the start. I need information to put into every little area and sub area that usually only a few numbers are provided. THEN when I get all the frequencies put in and think it is scanning,, not a PEEP. I hear more from my Analog scanner. Why does it have to be so hard? I spent hours for nothing so far. I have a $300 paperweight. UGH.
