STL/ RPU FREQs

[W4AQQ]

Is it legal to use VHF RPU freqs as STL freqs?
I have been hearing a station continously on 161 mhz on my VHF 2 meter rig.
WHat got me curious is the fact that they have a VHF yagi on top of their building pointed in the direction of their Transmitter/ tower
is this normal or better yet legal?
I have scoured the rules and could not find anything specifically allowing vhf 161 mhz as a STL freq
any Comments here?

You can use RPU frequencies as temporary STLs if necessary under 47 CFR 74.431(h).

It might be being used as an IFB frequency for remotes/live shots. Listen to it if the station is doing a live event and see if you hear mix-minus. I've heard that a number of times in the past.

\No....I am hearing the 161 mhz active anytime im in that town.they hav e live music shows in studio.that is on 161 mhz as well

It still could be an IFB link that the station just leaves up all the time. You are not suppose to just let it run even when not in use. Technically the 161 MHz RPU frequencies are not coordinated in the same way STL frequencies are, but then some stations......

exactly.I was beating around the bush but this station has been cited for other things in the past, here is why I suspect the RPU freq on 161 mhz is being used as a stl..they have a live in house program with bands ....they have bands into the studio to perform live....what I am hearing on 161 megs is the same exact stuff I am hearing on the am broadcast freq, ALL the programming I hear on the Air any time of the day is also being heard on 161 megs.......and point number 2.yagi is pointed toward the transmitter/ tower location, this station was perviously at another location and yagi atthat location was pointed toward the tower........but my question is.......escept for the situation preveiosuly pointed out by DEEP IN THOUGHT, is it legal to use 161 megs rpu freq as a daily STL freq?

No. But you'll probably never see enforcement unless someone in the area complains. Are they licensed to use that frequency for RPU?

Ah Ha, I know what station this is!

I wonder if their Cable TV operations are in the same building, I suspect their AM studio and cable tv stuff is in the same building....... thought maybe for a minute this could be a way to get audio from the tv studio to the radio station.

Kinda on topic, sorta... how does a LOCAL cable tv channel, say one owned by a radio station, get it's signal to the cable company's head end?

dang You Paul...You are right on Target.plumb across ths country

LOL Roy... I hadn't known you wer eon this board, but I recognized your call sign, looked up where that call sign belonged. .and when you mentioned live band performances, I knew it could only be one local station!

In many places, a simple dedicated wireline (either copper or fibre) to a headend is used (either pre- or post- final modulation). In others, the signal is modulated back onto the local circuit at a frequency allocated for return traffic on the closed system and demodulated and remodulated to the proper channel at a local/regional/master head-end. I'm sure there's other ways of doing it, but these are the ones that I've seen.
