From Michael Shoshani: "...San Francisco could receive programming from the
east for circulating on
this loop, and could originate both for the loop and for the east coast
(but not the latter while receiving programming), but other stations on
this loop could not feed back to San Francisco..."
My understanding is that programs to and from the east traveled by train in
the form of transcriptions because there were no high fidelity phone lines
across the Rockies until the 1940s.
