Just curious about this. You say "positions" so I presume you're setting up some kind of multi-op station. If that's the case, then I presume each op will be wearing headphones instead of using loudspeakers to copy the received signals. What made you decide to use boom microphones instead of a headset/mic combination?
The N2MO station has seven operating positions. We are still working out the kinks on antenna feeds, amplifiers and switching (including the speaker/headphones)
Anyway, here's a photo of the tech and HF positions at N2MO The QRP position and other QRO position are out of frame: http://sarex.us/n2mo/temp/radio_room_one.jpg
Re the booms - it was not a decision. We were loaned a pair of RE-20's and the booms came with them. It' should be a huge improvement over the stock handheld microphones.
