and in particular your AGC settings (SLP, THR) and if there was a loud 
signal, or loud high-pitched signal that was suddenly in the opened-up 
passband, and your NR settings in effect at the time.

Also, was the blast a loud burst of noise (like the gain was suddenlky 
turned up momentarily), or was it more like a shriek (a high pitched, 
perhaps unstable, tone)?
