FYI and preaching to the choir:
I think I have talked about all of the pieces but it is now put
together and working in the rain and wind.
125kb photo download showing setup. Second mic was not used for a
stereo image this time out, rather it was set at 20 db less volume
should I be priveledged to have had a bird displaying from on top of
the mic.

Discussion:
Set out the sound trap at dark 4:30. Timed record to capture grouse on
a lek from 5:30 to 8:30. Winds 10 to 20 mph and gusting to 30mph.
You have heard me talk about wind whistles from cables now you can
hear them. I need to find a right angle xlr connector for the mic
cables to add alittle more room for the recorder but Neutrix ones are
too wide to plug into the 722 properly. Temp was 34 degrees F and the
recorder case still felt 34 F after 3 hours of recording.
Next test project is to make current drain observations of the
recorder in Record , Playback, and waiting for timed record for both
hdd and cf card.

PS the Grouse did not dance in the rain and wind this morning but it
is still early season.
