Lou and John,

It could very well be the wind in the trees. I am still getting used to dis=
cerning ambient resonance from artificial noise in high amplification recor=
dings. The SD702 levels were set to 60.3 leaving enough headroom in case a =
caller came in fairly close. In post I added an additional 42dB which made =
everything super noisy before my eq. My goal with eq was to make it sound n=
atural even when I considered the ambient roar to be not natural.

The mics were set up near the bottom of a steeply sloped valley and aimed u=
p toward a crown of basalt several hundred feet ahead.  Behind, the slope w=
ent much higher and was covered with juniper and may well have been a sourc=
e of ambient sound in the steady light breeze. To the left the valley conti=
nued narrow narrow and upward. To the right the valley opened up down a few=
 hundred feet, and that is where our camp was and where the owls were calli=
ng from trees surrounding the meadow.

John, as to what I did to avoid wind rumble on the NT1As:
Mostly I jumped on the opportunity of the calm night and hoped for the best=
. My main rumble problem is not from wind getting through to the diaphragms=
, but from physical vibrations of wind resistance that carry through the sh=
ock mounts on this top heavy design. My rig needs to be reworked to lower i=
ts center of gravity I think.

And Aaron, thanks for the compliment!
