Loud Buzz end of Transmission

I have a 996XT and when listening to Redondo Beach there is a loud buzz at the end of the transmission. Sometimes this buzz will last for up to 2 to 3 seconds. Other stations don’t have this loud buzz only the usual noise that comes with un-keying a microphone. I’m wondering if this buzz is unique to the Redondo beach radio system and I just need to learn to live with it or is there a setting on the radio I can set to eliminate the buzz.


Thank you.
