Hello all , I’m new to the radio hobby so go ahead and bust my chops, I have big shoulders. I recently purchased the Mxt500 to use as a base station but I don’t understand why I don’t get any traffic on any channels even repeater channels. I’m using the antenna that came with it and I set it up on a galvanized garbage can in my yard on top of a table to basically simulate a car roof . I believe the repeater channels are open, I followed the book . But I get no traffic on any channel at all . Could it be the way my antenna is setup ??
