Many thanks to SRAA contributor, Dan Greenall, who shares the following recording and notes:

Broadcaster: Radio Malaysia, Kuala Lumpur 1971 (interval signal)

Date of recording: 1971

Frequency: 6.175

Reception location: Ancaster, Ontario, Canada

Receiver and antenna: Hallicrafters S-52 using a longwire antenna

Notes: Southeast Asia was one of the toughest areas to DX in my early years of SWLing from my receiving post in southern Ontario, Canada. Radio Malaysia from Kuala Lumpur on 6175 kHz made it through one morning in 1971 with their interval signal, then a very lengthy pause (about 35 seconds) before announcement in an Asian dialect. The lack of QRM and QRN helped to make this reception possible. For this, I was rewarded with their very attractive QSL card.
