Darryl,
Please explain these terms. I always thought aviation used the
outdated AM because that's what they started with many years ago.
After having used 2 meter FM radios for many years I find them to be
vastly superior to aircraft band AM radios.

The advantage of AM is that when two people talk at once you hear them
both. With FM, you get the strongest signal or, when both signals are
nearly equal in strength, you hear neither. I'll take AM for aviation
radio. For ham VHF/UHF, it's FM/SSB/digital. :-)
