Is there a way to make the two receivers in the radio act independently? I know I had this working before where I was scanning one set of preferred channels (public safety) on the left side and ham repeaters on the right side. Now, what ever I do on one side duplicates on the other1. If I skip a channel on the right side, it automatically sets it as skipped on the left. If I set a channel as preferred on the right, it changes on the left to preferred. What am I doing wrong? Is there a setting I am missing?
