[MilCom] USN Digital LMR's Other Than A/C Carriers?

[Greg Brazil]

Ken & all.  When I was a two way tech the beep meant you were using a 
encrypted radio in the clear.  Also have sold & serviced many systems on 
ships and UHF freqs. bounce around all that steel great.  At one point 
American President Lines had about 100 1 watt portables for the ships in 
the 457.xxx range with a 4 watt base & had full coverage of their ships.
