Hello i have a Uniden GMR-325 (7 Channels) Two Way Radio that....

Hi Zachary
I predict that you have trouble with only one unit.
Try to find some one with either the same units ( on same Frequency of course) or a receiver that also covers same Frequency and transmit on one GMR then the other to esablish which unit is faulty!
The faulty unit should then become apparent, the buzzing could be caused by transmisson of the faulty unit, check all Antenna connections, even change antennas over on testing as prescribed above,
good luck John.

It sounds to me like there might be a video processing problem in the scanner radome, or a break in the interconnect cable that runs from your screen to the radome.

If you did any work onboard recently that might have disturbed the interconnect cable please revisit the scene. If there was any kind of splice in the cable something may have come loose.

If the normal checks of tight, clean connections, adequate power to the display (which feeds the radome) don't revel anything, you may wish to call Raymarine or a local service dealer.
