Narrative:
When communicating with ground personnel over headsets after pushback but before they disconnect a local radio station interferes so loudly that I cannot understand what the ground personnel is saying. I have to have him repeat many times and speak very loudly to be understood. This has been a problem before but was so extreme on this flight and my previous one as to render communications over the plugged-in headset nearly impossible. The ground personnel did not seem to be having any trouble hearing me.

Title: A B777 CAPT COMMENTS THAT A LCL SEA RADIO STATION'S SIGNAL IS SO LOUD IN THE GND-FLT INTERPHONE THAT HE COULD NOT UNDERSTAND THE GND CREW.
Narrative: WHEN COMMUNICATING WITH GND PERSONNEL OVER HEADSETS AFTER PUSHBACK BUT BEFORE THEY DISCONNECT A LCL RADIO STATION INTERFERES SO LOUDLY THAT I CANNOT UNDERSTAND WHAT THE GND PERSONNEL IS SAYING. I HAVE TO HAVE HIM REPEAT MANY TIMES AND SPEAK VERY LOUDLY TO BE UNDERSTOOD. THIS HAS BEEN A PROB BEFORE BUT WAS SO EXTREME ON THIS FLT AND MY PREVIOUS ONE AS TO RENDER COMS OVER THE PLUGGED-IN HEADSET NEARLY IMPOSSIBLE. THE GND PERSONNEL DID NOT SEEM TO BE HAVING ANY TROUBLE HEARING ME.
