I recently installed a vhf marine radio and am having some problems with static, noise, or interference. When I power the radio on, it is fine. When someone talks or I talk static will follow and continue. Sometimes turning the squelch will make it go away sometimes it won’t. Other times the static will start on its own and continue. Sometimes turning the squelch will make it go away sometimes it wont. Also, when the static occurs sometimes keying the mic will make it go away sometimes it wont.
As far as interference there isn’t rally anything to interfere with he radio. I have even wired the radio to its own battery with no improvements.
Anybody out there have any ideas, do I have a bad radio, antenna, ground inside the radio, ground for the radio, ground for the antenna?
