I had an impression that these LP stations cannot go other way, but via satellite, to be received in very remote rural areas. Also, if you check an article in Wikipedia about RTN, it's RTN who provides a programming (very similar BTW) for all these local stations from the SAME UPLINK FACILITY.
Say, one station is OR, another in NY, but both receive same "Unreliable Sources" from AR.
Edit: sorry, it's not RTN, it's Equity Broadcasting, who is a provider, RTN is just a chennal name.
Quote:
"A trait unique to Equity Broadcasting is their usage of a centralized groupwide hub (called by Equity the Central Automated Satellite Hub, or
C.A.S.H, system) where all production, programming, and master control is handled from a facility adjacent to the company's headquarters."
That's not very expensive for them, I think
