Aero.Modes ?

[BOBRR]

Hello,

Sr. Citizen level questios, please.

Keeping track of "modes," has always been a problem for me.

Regarding "Aero." modes; am I correct that:

<30 MHz is USB ?

>30 MHz is AM ?

I imagine that there are lots of exceptions and caveats to this.

*If anyone could list and discuss any exceptions, would be appreciative.

Thanks, as always,
Bob

Basically yes the only exception I can think of is public safety and military aircraft they can use public safety frequencies, conventional and trunked, to communicate with other departments
