As I understand it, the latest is voice capable, but not duplex. Not sure if the website is up to date, or if my brother is working with the newer prototype models(?). While I was a radio operator in the past, that was many moons ago, so you guys are probably (Likely) much more up to speed on this sort of thing. Hell, I was still humping a PRC-77 and KY-57 back then, the highest speed, lowest drag thing we had was a LST-4 (SATCOM) and PSC-3 antenna...and we thought we were the shit back then.
Curious as to what else you guys are thinking wrt this type of setup, and other options. Comms have certainly come a long ways...
