Joel, this may not be what you are getting, however, last night I noticed if I set the "RF Gain" (AGC) too high, I would hear this fast pop about every 4 seconds or so. After messing with buffers and such, I discovered I could reduce the max AGC and this would go away. Is it possible this is what you are getting?
