[PSUBS-MAILIST] OTS comms headset.

I just realized I gave bad advice to David about latching the PTT, because I wasn't thinking straight. SSB-2010, or in fact any acoustic unit, will be PTT only. Only 4-wire hardwire systems can run full duplex, so you never want to latch / switch your PTT in the sub to be always on, lest you not be able to receive any transmissions.

Nyutco modified his headset to use two boom mics, one for VHF the other for UWC. I don't remember how we switched between the two transceivers though. Maybe someone else does.
