Hey, guys, Someone here already said it, but nobody else got it, so I'll repeat it: SSB, or Single Sideband. It's commercial ham radio, if you will, and all the ships use it. I expect that you can shove anything down an SSB set that you want, including encrypted traffic. Ham radio is a government nerd subsidy, and as such, doesn't do much but make more government funded/sactioned/approved/whatever nerds. :-). SSB would do just fine. It's an international standard, after all, and probably not under the control of any one government, even.e Cheers, Bob Hettinga ----------------- Robert A.
