For my reception report to email@example.com I received a friendly email announcing that a QSL card was to be sent. And indeed a few weeks later I received a traditional and beautiful QSL card by mail.
The station is also referred to as Madagascar World Voice and operated by World Christian Broadcasting. They are also the organisation behind KNLS from Alaska. Because of their extremely northern location in Alaska they sought a second transmitter site in the southern hemispere. Construction started as early as 2006 but was delayed due to cyclones and national political issues in Madagascar. Broadcasts started in 2016. Palavra Alegre is the name of their Portugese programme directed to Brasil, but note there are also 6 African countries with Portugese as the official language.
