BRAZIL Brazil Launches DRM Shortwave Test.
Brazilian public broadcaster EBC-Radio Nacional da Amazonia recently began
a shortwave (9750 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.

BRAZIL First DRM mode test for a SW station in Brazil.
The article is in Portuguese:
<http://www.drm-brasil.org/content/primeiro-teste-de-emissora-brasileira-
em-drm-na-faixa-de-ondas-curtas-acontece-com-sucesso>
In a rough translation it reads that on May 28, 2015 occurred this first
transmission.
EBC <http://www.ebc.com.br/>
operated with the collaboration of a number of partners in the afternoon
of that day with 130W on DRM on 9755 kHz. The DRM signal was successfully
received in part of the country. In Limeira, a city in Sao Paulo state,
780 km far from the transmitter site, Mr. Claudio del Bianco, member of
DRM-Brasil, received the signal and could hear to the audio from Radio
Nacional da Amazonia with digital quality.
The set-up of the system used for the test, had the support of DRM-Brazil,
and a joint effort was made. The software was provided by Content Server
and the modulator was provided by Michael Feilen. Rafael Diniz, a DRM-
Brazil member and researcher at PUC-Rio, released the DRM driver and the
first amplification stage. Members of the EBC and the Ministry of
Comunicacoes have provided two stages of amplification and all the
required connection with the radiant system at Rodeador Park (High Power
Shortwave Broadcast Centre of EBC).
The antenna used has a 16db gain factor and the pattern of radiation was
North-South.
On this Monday, June 1, new DRM SW tests will take place.

EBC Rodeador Park.
Laut Glenn bei dxld hat man mal wieder DRM Testsendungen mit verschiedenen
Antennen(-winkeln) in Richtung riesiges Amazonasgebiet vorzunehmen. Dazu
nutzt man einen der dortigen Continental Sender mit 4 bis 10 kW
variierend, teilweise auch mit halber/reduzierter Leistung 125 kW -
tagsueber.
Passend laesst man dann (in unserer Nacht) den Sender auf 6000v zugange -
aber in AM Modus 'on air'. Antennenwinkel ist dann 344 Grad, nicht gerade
"unsere Vorzugsrichtung" ... - Hier alles schoen zu sehen, downzuladen und
nachzulesen:

Geliefert wurden einst mal 6 Schweizer Produkte:
6 x 250 kW Kurzwellensender, delivered by Swiss BBC-Turgi Switzerland,
model SK53F3 from 1974-1976y.

WTFK? Nowhere in the English or original Portuguese article is there
anything about the frequency! Maybe known channels 11780, 6180 or 5990.
And 2.5 kW doesn`t cut it as anyone who has tried DRM would know,
reception iffy even with much more international power. Probably will not
be solid even into Amazon target. 7 million river-dwellers and indigenous
to be served? Wait, are they all going to be given DRM radios??? The video
of test in Porto Alegre shows a DRM radio but can`t see what frequency
it`s tuned to; local lab range anyway. Pipe dream? They ought to fix the
awful modulation on high-power AM 11780; and what`s wrong with 6180 as is?
