Radio Nacional da Amazonia - Brazil

Radio Nacional da Amazonia in Brasilia, Brazil was logged on 28 March 2011 and monitored between 10.30 to12.00 UTC on 11.780 kHz. Programming was in the Portuguese language and entailed essentially a talk format with occasional Brazilian pop music interjected during the broadcast. 

Brochure cover
Signal (SINPO): at 10.30 UTC signal was 45344 - fair reception with some fading; at 11.00 UTC signal was 33343 - interference from nearby stations caused some modulation, but speech was still audible; at 11.30 UTC signal was 22232 - barely audible speech and a lot of modulation from nearby stations; at 11.45 signal was 11121 - too weak to discern speech; after 12.00 UTC signal was detected but just too weak and too much interference from nearby stations.

This is a rather remarkable find, considering Latin American stations are rarely heard in Malaysia. Moreover, their transmission is aimed primarily to northern Brazil. Receivers used to catch this station included a Grundig Satellit 750 (Tecsun S-2000) and Grundig Satellit 500, attached to a 1/4 wave antenna elevated at a height of 10 meters and fed through a 50 ohm coaxial cable linked to a MFJ-956 antenna tuner.

Reception report was submitted by mail and email. Letter and brochure were received on 24 June 2011 in lieu of a QSL card, which more or less confirms my reception report, I suppose.

  1. Did you send a QSL report to the listed address? I just received them and have a report to send. I am in Chicago, so its not as nice of a pickup, but still cool.

  2. Hi Stephen.

    Yes, I did submit a reception report to Radio Nacional da Amazonia at this address. I also emailed them. They have emailed me on numerous occasions since this blog posting, informing me in Portuguese to re-submit my email reception report to: centraldoouvinte@ebc.com.br. WRTH 2011 confirms the address too. As far as actually receiving a physical QSL card from them, I am still checking the mail box for it.

    I do know other short-wave listeners have received QSL cards, letters of confirmation and postcards from them.

    I can understand Radio Nacional da Amazonia is not exactly an exotic radio catch for you since it is kind of in your own back yard, so to speak.

    I used to receive many stations from Central and South America when I was growing up in the States -- Denver, Colorado is home -- and I was never too enthused to contact them. Still, you should contact Radio Nacional da Amazonia.

    Keep in mind some of these stations that you QSL now may not be around in 10 or 20 years. I have QSL cards from many now defunct stations, i.e. Radio Berlin International, Radio Tahiti, Radio New Caledonia, Swiss Radio International, Radio Italia (RAI), Radio Budapest, Radio Norway, Radio Sweden, Radio Peace & Progress (USSR).

    Worst still, some stations that once sent out QSLs may eventually refuse to issue them; BBC, Radio Exterior de Espana and Radio Riyadh are just a few who no longer acknowledge reception reports with a verification card.

    I am finding stations in Africa (Nigeria, Libya, Tunisia, Morocco and South Africa) and the Middle East (Oman, Saudi Arabia and Bahrain) are especially difficult for me to obtain QSL cards from after sending a report. Some African, Middle Eastern and Asian clandestine stations that have European or US addresses are also no shows. How about you?

    All the and 73s!
