I have determined that there is a distortion problem with some of the O2's
effecting the audio quality. Like yours, mine is excellent, but I have
heard at least two O2's on the air that were tested in a variety of
situations including different microphones, antennas, amps, power levels,
grounding schemes, etc., and the audio problem was still there. One unit
with a similar problem was sent back to TT more than a month ago and was
still there as of the week before last.
My website, www.ronc.users.sonic.net documents a 6 dB loss in response at
100 Hz from the factory spec. The rest of the audio spectrum looks fine and
with fairly low distortion. The low-end loss can't be fixed with the
internal equalizer without making the lower mid-range to strong, but an
external graphic or parametric EQ can do the job.
There is nothing wrong with Heil mics, it's probably a coincidence because
there are so many out there.
