Deep double nulls. Occurring approximately every 4 to 5 seconds. Duration probably no more than 1.5 seconds. I do have a wave file if you want it but it is 16mB in size.

Are there any deep nulls in the fading? If so, how long are they? I designed the interleaving to tolerate deep fades of up to about 1-1.5 seconds as long as they don't occur more often than about once every 15 sec or so. Shorter fades can be tolerated more often.
