Hello again. I opologize in advance for posting similar posts.as i am unfamiliar with the motorola gp68 and the manual is very confusing. I have programed all of the frequencies and pls correctly, but when i am in scan mode, i know i receive a signal because i see the bars on the screen but i get no audio until i hit the monitor button or the sig button (button a). When i monitor a single channel it will pick up the audio automatically. What am i doing wrong please help.
