just as an update... i have recorded a couple of additional times with the same set up and no problems...
my guess, the phish environment caused the problem... i know - it's not scientific... but my reasoning is that:
a) there was a lot of traffic on that aisle maybe something happened in the traffic (bag kicked, mic cable pulled),
b) there was a lot of cell phone use around me (including me) - but it didn't sound like traditional cell phone interference,
c) it was the phish... and if there is ever a sport taping environment that is the place... a shit ton of variables.
i will be using the mp2 again this weekend, although this time with the ho's in front of it... hopefully it has all worked itself out.
