OK from my understanding of what a Decca Tree is it is essentially
three omnis placed at the end points of two back to back right angles
http://tinyurl.com/5qz88d

so for example, the distance of A & B & C from x is '1 unit' distance
thus the distance between A&B would be '2*unit' distance

             C
             |
A--------x--------B


all three mics are omni's in a Decca Tree but there has been  
experimentation
with mics other than omni's being used in the middle position such as  
an M-S mic

so I'm wondering if anyone has taken an actual Decca Tree rig out  
into nature and made recordings?
