And Tony, you're sure your problem eventually goes away completely? Or is it just harder to hear because of the content at the time?

Certain. It fades in over a period of about 3-5 minutes, then fades out over a period of about 3-5 minutes. At its peak, it is ear-splittingly loud, drowning out the program content.

How quickly it fades in and out seems to be dependent upon how cold it is that day. If it's very cold outside it takes a long time to fade in and out. On a warm day it's very quick.
