Many thanks to SRAA contributor, Manfred Reiff, who shares the following recording and notes:
This second [Radio Afghanistan] recording was made at the end of the 1970s during the soviet occupation of Afghanistan when RA programmes were rebroadcasted via Soviet transmitters. In this case it is the english service beamed to several parts of Asia.
The recording was made one some day at 0900 GMT on 15435 kHz. It was a relay via Soviet transmitter.
