If M42Duster had an issue with his Optima I am sure Dave at Yeticom offered to take care of it. To be bashing a company that makes a great product is just not nice. I do NOT work for Yeticom or sell their radios I am a customer like the rest of you guys, why M42 Duster would bash Yeticom just does not make sense to me. My MKII had that same problem all you have to do is turn it off and back on the display works fine again, why did M42Duster make a big deal out of that?? Mine did it if I left it on for like a day or longer, not sure about you guys but I turn my radio off at night, it's not a Galaxy that needs to be on all the time to work right. One night I did leave my Optima on by accident, went to work the next day and didn't get in front of the radio until dinner time and the display was weird looking. I turned it off, turned it back on right away and used it the rest of the night with no issues. I don't feel that is a reason to talk bad about anything electronic.
