We went into the field again yesterday AM and found the same pop and
click issue with the same
device that introduced it a few weeks ago. While I believe now that
the problem is internal, the pops are not equal level across both
channels. I. e. one channel contains a "click" at a higher level than
the other. So it's probably not the (internal) mics.
Also, yesterday, we got a serious sampling error (loud electronic
noise overload across both channels) that lasted about 2 seconds. This
is all very curious. Olympus tech support has offered to change out
the unit so we hope that will eliminate the problem. Stay tuned...
