In the 1950s and early 1960s 5CK Crystal Brook used the "experimental" FM broadcast as backup programme source for its physical line. The PMG was in a cleft stick: they were obliged to discontinue the (beloved of HiFi enthusiasts) FM service but needed a reliable 5CK, which serviced the whole mid-north. The solution, worthy of Gilbert and Sullivan or Monty Python, was to scramble the audio with a pair of locally-engineered frequency inversion boxes. Transmission continued but was useless to audiophiles. Problem Solvered! Doug butler (talk) 22:49, 19 July 2025 (UTC)[reply]
