Actually, if the radio has been disconnected from the antenna and he tried to transmit, he probably blew the finals in the amplifier section of his CB. If he is getting a signal out, although a poor one, the comment about tuning the antenna for SWR is correct. The meters are inexpensive at a Radio Shack or one of those truck stops that sells CB stuff and they come with instructions on how to use them.. A properly tuned antenna is absolutely essential with these low watt units, especially with the antenna mounted to one side of the bike as they all are. If he has a high SWR, he might only be getting out a watt or so and a quarter of an inch or so out of tune will make a huge difference.
