An article from Malaymail online. I am not sure what the “FB” means in the first line, but they probably mean “Radio R double A F Butterworth”. (Or Radio RAAF Butterworth!)
SEBERANG PERAI, May 23 —
“This is Radio R double A FB!” Now, that brings back memories… to Penangites who grew up in the 1970s.
In particular, they would look forward to Saturday nights when their song dedications were played throughout the night on Radio RAAF Butterworth.
The Australians took over the air base from the British in 1958 but the 1970s were really its golden years as its personnel and dependants grew to almost 5,000 people, all living around the state in Butterworth and also on the island.
