Some details pique my interest. The article repeatedly refers to it's connections to WFIL and Havertown. WFIL had given them a $50,000 grant to develop and run a broadcasting curriculum. So they remained tightly tied. "WRTI will have wires to the Cedarbrook and Havertown units and one to the master control room of WFIL" Cedarbrook and Havertown were remote facilities of Temple University, that were closed in 1951. It's just a coincidence that in the late 1940s that two of the very few non-commercial radio facilities in the US were in the same zipcode: WRTI and WHHS. Temple didn't get an FM transmitter until 1952. The rest is history.
