Narrative:

During descent into sbgr we experienced a loud squeal on brazilia center frequency 133.45 making communication unreliable. I advised center of the situation and was told they had no other frequency available. Lucky for us; the WX was good and we were cleared to descend via the STAR with no other communication needed. We landed uneventfully at sbgr. This is a common occurrence arriving at sbgr and feel that someone should investigate before an accident occurs due to missed radio calls.
