Do broadcast guys regularly use their IFB or other frequencies for general chit chat like a couple of hams like that? Genuinely curious as this sounds like two guys who just put a frequency into their baofeng or similar Chinese radio and went with it.
They use them for regular two way use yes sometimes, but for station related ops and usually onsite simplex. But there's none of those out here though, all the OTA TV stations are satellite/microwave fed from the nearby by out of town affiliates in Phoenix and the cable channels as come from elsewhere too. As for our local Cameron AM/FM stations all those shows are phoned/VOIPed in for any local programs with the rest being satellite fed from FOX, if you go downtown on the east end of Beale Street you will see their dishes on their building next to the new Daily Miner offices.
I did extensive FCC digging all over this state and neighboring just to be sure before posting the video and your BaoFeng theory seems the most correct. That kind of use is pretty popular out here among the radio interested people including myself. I've been doing that for over 10 years now on out of the way empty frequencies to avoid the butt-ins spinning the dial on the HAM simplex ranges when chatting with friends. I've even seen some railfan kids doing it too.
Oh and also one of our local Taxi companies I'm pretty sure was doing that as well when they still used to use mobile radios on 451.925, they tried to employ scrambling then eventually just abandoned the whole repeater a year later after noticing me monitoring in public a lot
I haven't checked whether the repeater hardware is still there and turned on still yet.
