Could you trigger them in an interleave-like sequence? Seems that would
reduce interference to just about zero. If you number 1-2-3 starting at
zero degrees and going clockwise, you could set up the following firing
order:
1, 5, 9, 13, 2, 6, 10, 14, 3, 7, 11, 15, 4, 8, 12, 16
that way every transmission would be 90 degrees from the last and not
likelt to receive anything from the previous transmission.
