Hello, new to the forum here. A lot of great information and I appreciate you all having me. Here is my issue. I have a Galaxy dx959b. Everything appears to work fine but when the radio is turned on, there is a high frequency noise, almost like the ringing in your ears. Not very loud, just loud enough to annoy me. It is always audible, during transmit or receive, when the radio is quiet or noisy. RF up or down, Squelch up or down. When its in the truck or on the bench. It is not engine noise but sounds like it is a component that is putting the noise out. I cracked the case and looked inside and everything appears to be stock. All of the solder joints look stock, everything appears to be tight. An insight would be helpful. Thanks for you time.
