What is a Full Power FM Experimental STA?

[stlouisx50]

I was wondering why some stations such as FM and AM radio, get classified as "

Full Power FM Experimental STA "​

What does this even mean?

The odd thing is the statuons are registered as St. Louis FCC License Sub, LLC.

Is this a government station owned by the FCC?

STA = Special Temporary Authorization.
The licensee is probably some shell company. Using the "FCC" doesn't mean it's part of the Federal Communications Commission.

It means that they are doing some sort of temporary experiment. Might be for any number of reasons. Can you send the call sign for said station?

There is
KPNT 105.7 The point
KSHE 94.7
WIL-FM 92.3

Some of the OG radio stations that haven't really changed.

Do you have a link to where you are seeing the STA's for these specific stations?

The FCC has been more generous in allowing FM translators to AM stations who have trouble penetrating buildings in the central business district. Usually FM translators are low power (less than 100 watts)+ low antenna but I have noticed some are high power/high antenna translators by special temporary authority (i.e. STA). By FCC rules the translator cannot be licensed by the owner of the AM station it repeats.

The noise level is becoming so high from DC to 150 MHZ that once 50 KW boomer AM stations are now dead in the business district.
