Hello,

Am trying to get some data bases in order, and would like to ask the
following, please. Modes, knowing the correct ones, has always been a
bit of a problem for me.

Am in my 70's now, and would appreciate any help, very much.
Still enjoy the hobby a lot, though.

My main question: are the FBI frequencies that are not encrypted
like 163.900 and 170.300 all FM ?

and,

a. Mil Air: I've been assuming AM, but are any bands or
frequencies USB ?

b.HFGCS Mode ?

c.Navy Giant Killer Mode ?

d. Air Refueling Mode ?

e.Norad Huntress Mode ?

f. FEMA Mode ?

g. LODAC (not even sure what it is; might it be LODOC ?) Mode ?

Much thanks,appreciate the help,
Bob
