Brazil DRM Shortwave Test

Radio World report Brazilian public broadcaster EBC–Radio Nacional da
Amazônia recently began a shortwave (9.750 kHz) Digital Radio Mondiale
test, transmitting DRM30. The test is being organized by the Brazilian
Digital Radio Association (ABRADIG) and EBC with support from the DRM
Consortium.

A low-power transmitter (150 W) has been installed at the Rodeador
site in Brasilia with the goal of assessing the behavior of the
equipment, signal quality and system stability. Thus far, reports
indicate that the signal has been detected all around Brazil and some
intermittent signals were received in New Zealand.

The trial began on Oct. 28 and the plan is to keep the signal on air
permanently throughout the trial; there is currently no set end date.
Tests are being conducted using different antenna patterns and
directions. According to DRM, the receivers used in the trial are
spread across the country and are owned by ABRADIG. It also said that
EBC stated it plans to acquire a more powerful transmitter as soon as
possible.
