Is there anything worth monitoring above 1300 MHz? Just
wondering.

Depends where you are at: Have a friend , has a
10 GHz beacon, in Puget Sound, as well as a 1296
Beacon ( W7HR) and gets copied out to couple
hundred miles (or so), and occasionally, much
further away (these, as he described, are aimed
at Mt. Rainier). Long haul by Tropo ducting, ect.
Mighrt have others running by now! Jim NN7K


Ah, ham beacons/MW activity ... an exception I hadn't considered for
scanner usage. But the discone that guy bought wouldn't be more useful
than the Diamond for activity at 10GHz, I'd think.
