Hi Phil,
See my other post from earlier, some screenshots demonstrating the signal fading. They are hosted here:
Will have more comprehensive shots on the next pass (AOS in 31 mins from now)
At a quick estimate on the pass I saw (0.9 degree elevation) I would say a 2 second null then 6-7 seconds of good signal repeating.

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.
