I have installed the OEM CB radio and antenna. When I try to set the SWR with the meter, I get a reading above 3.0 on channel 1 and above 2.5 on channel 40. I cannot get the reading on either channel to drop to the acceptable level of 1-1.5. I have tried to lengthen with washers, but the needle reads the same. I have removed the OEM antenna and installed the antenna from my car (which I know I get an SWR reading of 1.2) but I get the same SWR reading from both channel 1 and channel 40 (above3.0 and 2.5) Does anyone know if there is an adjustment within the radio that could help solve this problem. These readings will damage the CB if it is used.

Thanks for any comments or assistance.
