It's basically a Cobra 25 GTL vintage , got the radio and it was a virgin , The problem is this , when you turn it on (just on with no volume) there's a static white noise if you will that will come out both ex.speak or internal speak) ? when you add volume the receive is fine but that white noise static is still there ? the noise shows nothing on the S meter at all. You can squelch it out , (but that also takes out the receive as squelchs do) using the rf gain all the way down and the static is still there. Using the PA , the static is there also ? will go away once you key and apply audio , but is there after you unkey. The same static that is there when you just turn on the radio without adding in coming volume to it. Any ideas whats going on with this one ? Thanks
