I get feed back with my LS-11 and ME-67 microphone when I'm running high
mic gain and aim the microphone (on a pistol grip) upwards in front of
me.  But you are correct, in my case its picking up the sound in my
headphones which causes the feedback loop...  Peter didn't mention if
headphones were in use or if recorder speaker was in monitor mode, I
assumed that like most of us he uses headphones for monitoring and you
can definitely get feedback...

However, in light of Peter's more recent reveal that he had the recorder
sitting on the array, I'm more inclined at this point to think that the
array was picking up the recorder, most likely radiated digital hash
based on the spacing of the bands up through the spectrum which would
explain the consistent level and spacing of the bands....
