Several months ago I purchased a FT-60 and have read everything that I can get my hands on and have watched every video and still can't do anything except listen to the weather.? This is my first radio and I am brand new to the hobby.? Several local repeaters are loaded on the radio but when I hit the PPT I get a red light.? What am I doing wrong.? I figure after reading comments from others that I must be missing something simple.? Thanks in advance for any assistance offered.
