Thanks guys.

Some things I would be testing out in Danville would be the reception range in a 2.4gHz-noisy environment. One of the guys back home couldn't get a pairing on his setup (not a Brookstone) when six different 2.4 radios were active at the same time.

Another thing I'll be testing is whether the night vision IR emitter beam interferes with battle unit IR reception. You can see it is a very wide beam covering the entire frontal hemisphere - I don't know enough about IR beams to know if that becomes a form of "IR jammer" like the AN/ALQ-144 "disco ball" you find on the spine of a Blackhawk helicopter. It is unlikely the night vision beam kills enemy tanks, though, because there's no coding in the IR beam. Nevertheless, it would not be fair at all to hamper the sensitivity of my IR apple.
