Really? How were we coordinating and licensing ACM well before that?

Licensing adaptive modulation has only been legal (in the US) since Oct 2012,
so the vast majority of licensed paths will be licensed for one fixed

There are a lot of old telco paths licensed with fixed 30MHz and 128QAM.
They usually have large antennas and lots of Tx power. You'll see their receive
power in the -20's. I guess they don't want fade. :)

I can't imagine why anyone would have licensed this path this way.
Oh well.

Yup, fixed.

I'm looking at a path in ULS that only shows one modulation type.
I've seen others in the past that will list several modulations.
Is this path ONLY allowed to use 16QAM? No ACM permitted?
