I have a Honda line CB with a quality J&M open face headset on my 05 Wing. The CB has not had that much use yet fellow riders say I'm not clear on transmission. :croc: SWR's are a ratio of 1 1/4 to 1 I have plenty of carrier. I don't have a problem talking to truckers. However, their cab environment is somewhat better for listening to radios. My hand held mic with the bigger capsule comes through better. I have all the filters installed and don't have a problem with noise. Have run out of ideas with this darn plug and play setup. :rain1: It seems like I need to add some preamp power to the mic. Any ideas?
