Poor Transmission (Garbled)

31, hi, is this some sort of a business band radio or a CB radio? Make sure your power wires are large enough to carry the amperage the radio needs. Have you done any kind of SWR check on the antenna system? Make sure the coax does not have a short in it. Make sure you did not splice the power wires with a "scotchlock", those thing do not make a good quality connection. Hope this helps you, and if not reply back here with some more info for me to help you. Thanks Mechanic
