Hello:

New at this.

Have a large listing of airline freq's used at Logan in Boston.

They are generally:

a. 450.xxx - 470.xxx

b. 897.xxx

c. 936.xxx

d. and ARINC freq's around 130.xxx

Not at all sure if these are air to ground, or just ground handling freq's.
What do you think ?

For (a), (b), (c), and (d), what modes should I program my
780 for ?

My Butel software automatically pegged them
all as NFM, but if they are (?) air to ground, wouldn't they be AM ?

Much thanks,
Bob
