I'm new here searching the web for help. Maybe yall can lead me in the right direction. I have a 98vhp and just recently took a new job. It was set up in my peterbilt and worked great. Now I have a Mack CH600 and the SWRs are high, I can't turn the power up at all or the radio starts pulsing and the lights start getting bright and dim bright and dim. The mic shocks me. Anyone ever experienced these problems before? What did you do to fix it. Thanks in advance.
