CB or antenna problem
 

Been noticing that it appears i'm not getting out recently on the CB, checked the SWR's and they are good (Cobra 29LTD NW, has built in SWR cal and meter)... Tuesday a driver was calling me and when I answered him someone else stated that I was keying but no modulation... the antenna's are old cobra's that were on the truck when I got it... could this be a radio, antenna or mike problem?

Thanks

Take the radio and the mike into a cb shop to have them test it. Shouldn't cost much, if anything at all. It's probably the mic though.

check the mike gain

I would check the antenna(s). Check for cracks, breaks, and look at the base. Some fiberglass antennas break loose at the base. You also might want to stop by a CB shop, and have them check your radio, and mic. Also, check the nut on the mic cord, where it screws into the radio. It that nut isnt tight, it wont work well, either.

Had the mike gain almost all the way up.. at times I'm able to talk and at times not.. I'm leaning towards a mike problem, but will have it all checked out..

Thanks :D
