Many thanks to SRAA contributor David Goren, who shares the following recording and notes.
This recording captures Radio Macapá, Brazil, clearly identified several times on the air. David discovered it on a cassette tape.

While the exact date is uncertain, David believes it could be from 1988, though he notes he was still recording to cassette into the early 2000s. The absence of CODAR interference—common on the bands starting in the early 1990s—suggests the recording likely predates that period.

Though not as unusual as some of David’s other finds, this recording remains a fine example of Brazilian shortwave broadcasting and a valuable slice of radio history. Enjoy and feel free to comment with any other details that may help date this recording.
