@overther166 You must check your SWR this can cause a problem if it is not set correctly. You can also try an external speaker to see if it is a speaker issue.
ive bought one of these and installed it using a gutter mount on a land rover but seem to receive only very people so im guessing the aeriel needs to be earthed out , whats best way to do this
@overther166 if you purchased this radio through BuyReliant website our tech department will be happy to assist you in trouble shooting your problem. If not you need to contact either Cobra support or the company you purchased the radio from for more information.
my swr is really high, i cant seem to lower it no matter what. I moved my attenna to different locations on the truck but it still stays really high. I have it hooked up to the truck battery
