I don’t know I’m just surprised that there’s a station like that out there and how it’s not really regulated
It's regulated more than you'd think. There are certain lines that don't seem to be crossed, and try as you might, there doesn't seem to be any rule in Part 97 that disallows much of what goes on there.
Yeah, they could get nabbed for not ID'ing or playing music, but how do you know who's not ID'ing or playing music unless they ID. DF them? Who's got the time? Profanity? Well, that's a tough one to pit against the first amendment. Probably not the hill the local FCC field engineers want to die on.
Let it leak onto other channels and generate complaints, well, then you're more likely to see some action.
The FCC considers "community standards" in defining what's profanity and what's not. In THAT particular community, the definition is pretty loose. So they don't chase after every "F" bomb that emanates from the repeater.
So, the above is all my opinion, based on 40+ years of activity in the Southern California FM "scene", discussions with OO's and FCC field personnel, and personal acquaintance of some of the players on the channel in past years.
Actually, many of those guys are quite intelligent and accomplished, and .435 is where they let their hair down, so to speak. They know it shocks people, so that 'feeds the need". It's (usually) self contained, doesn't cause problems (much) elsewhere, so it's allowed to carry on.
I don't care to listen to it, so I don't. I make that suggestion to everyone else who's offended. It's easy to not be offended by what's on the radio. Just turn it off.
