Ok I really need a cb expert here.So heres my problem.ON ptt transmit mode I hear alot of engine noise.When bike is off there is no noise.Heard lots of solutions but every one is guessing.Dont need that.It cost to much money to guess.Also today I thought of trying to hook up to the rear port to see if it is the same and to my supprise I can see the cb light up but cant hear the transmission. related hum maybe. But I do need someone who really knows about these systems. thanks
