Many thanks to SRAA contributor, Greg Shoom, who submits this recording: a compilation of clips from various shortwave stations, circa 1977. Greg didn't note specific dates, times, nor frequencies when he originally made the recording, but he has notes some details of the clips included:

Shortwave Compilation, Early 1977

Transworld Radio - Interval signal and ID.

Radio Veritas ID, as heard on Radio Nederland.

Radio Nederland - The story of Radio Nederland's French language service interval signal (in English).

Radio Nederland - Clip about interference in Scandinavia from Soviet over-the-horizon radar on shortwave.

Radio Santa Fe ID. Probably from Radio Santa Fe, HJAF, Bogota, Colombia, which used to operate on 4965 kHz. I don't know if this was my recording of this ID, or one I heard on a DX program.
