An article from another Blog about BBC Radio 4.
BBC Radio 4 can be traced back to experimental Mediumwave Radio Station 2LO. 2LO is the cornerstone on which the BBC was founded on, in 1922.
2LO, in its original incarnation; would remain on the air until March, 1930.
The Studios and Transmitter Site of 2LO were located inside of, and atop Marconi House; located at 335 Strand Street in the London city proper.
