The report on the successful trail of shortwave in DRM for domestic use
in Brazil was recently published. The trial at the end of 2020 and
beginning of 2021 was a joint effort between The Ministry of Science,
Technology, Innovation and Communications in Brasilia, the University of
Brasilia, EBC – the public broadcaster, the DRM Brazil Platform, and
other commercial enterprises and interested parties. The aim was to get
extensive coverage in DRM SW especially over the wide and sparsely
populated of the Brazilian northern areas, the rich Amazonian region.The
report gives a detailed report on the set up and results of the DRM
trial and demo. It concludes that: "...the successful realization of
Phase 1 of the project necessarily implies continuity, with the
development and dissemination of national low-cost DRM receivers in
Phase 2. One cannot lose the "savoir faire" or knowledge acquired so far
and thus condemning isolated populations to ignorance due to lack of
information. This opens up a new perspective for quality communication
over long distances, integrating the most distant regions of Brazil."
