Wonder if - lacking an order top stop from the FCC - I could occupy a frequency and ultimately claim squatters rights or adverse posession on the frequency if someone eventually licenses it.
Adverse possession traces its roots back to the Homestead Act of 1862. I'm not sure how exactly you'd claim you were making a residence out of a radio frequency.
adverse possession is quite a bit older than 01862, kid
No. The airwaves belong to the public, as licensed by the FCC. You don’t have any squatters rights to the airwaves.
I'm not talking about durable squatters right. More akin swimming in the ocean or hiking a cross a field
The FCC hasn’t historically supported that. One of the early FM pioneers was ruined when Sarnoff lobbied to allocate his frequencies for another purpose, for example.
The spectrum is pretty much regulated all the way up to microwave bands and beyond.
