If it would just stay broken for a couple hours, I'd love to do that.
Sadly, this problem usually just shows up for a minute or two at a time,
and never more than about fifteen minutes.
The boss and I have tried that before, and the problem is just too
intermittent for us to be able to narrow down that way. Of course, our
spectrum-fu is not that strong.

David,
We have a similar situation happening mainly on one tower of ours.
Basicially it is a StarOS V2 on WRAP boards setup using Prism cards
for the AP's. We have 4 90* horizontal sectors. Everyones's signals
are great and it runs fine most of the time. Occassionaly we see times
where people have 10-20% packet loss. We look at the traffic on the
tower for abuse and/or virus and don't really find anything. We've
tried different channels and it doesn't seem to help. Other times
there is no loss at all.
Most of our clients on CB3's but we do have some Orinoco based
clients. The Orinoco based clients don't seem to have the problem as
much as the CB3's do however. I have not really pinned down what the
difference between them would be that would cause the Orinoco's not to
show this behaviour even though their signal may be somewhat lower.
We've taken a spectrum analyzer up the tower and don't really see any
other signals that are really "hot" out there but it feels like an
interefernce problem. Unfortunately, the tower is about an hour drive
so catching this while it happens has proved somewhat problematic.
In anycase, "I feel your pain". I'll let you know if we figure out
what this issue is.
