I have a 2005 Harley Ultra Classic. I bought a Hand held Harley CB Mic. to use instead of the Head set. When I use the PTT button to talk on the CB through my Harley Head set. Everything works fine. But when I key the Hand held MIC. No one can hear me. Trying to figure out what the problem is. The radio dies down as when pushing the PTT button when using the Head set. But no one can hear a thing I'm saying when I depress the Hand Held Mic Button. Any clues how to fix the problem.
