Hello:

New athis hobby.

The following, I think, but am not sure, are Coast Guard Aero frequencies.

Can anyone perhaps verify that for me, and irrespective of whether they
are, or not, please tell me whether they are AM or FM:

123.100 - U.S. Coast Guard - VHF S.A.R. Primary
122.900 - U.S. Coast Guard - VHF S.A.R. Secondary
381.800- U.S. Coast Guard - UHF S.A.R.
282.800- U.S. Coast Guard - UHF S.A.R.
126.200- U.S. Coast Guard - Ground-to-Air Operations

Are "all" aero related freq's over 30 MHz always AM ?

Thank you,
B.
