A Transmitter Park In Brazil Is Celebrating its 50th Birthday!

The facility 40km northwest of Brasilia originally cost $15 Million USD to build and will turn 50 years old on March 11, 2024. It’s home to several SW, AM and FM transmitters , including Radio Nacional de Amazonias on 6180 and 11780khz. The stations owner, Empresa Brasil de Comunicação , a government owned agency plans to recognize the facility’s Gold anniversary.

University of Brasilia and the Ministry of Science, Technology and Innovation to experiment with 2.5 kW DRM transmitter

(Source: DRM Consortium)

A new era begins for Brazilian radio broadcasting with the arrival and installation of a first shortwave digital radio DRM transmitter developed and manufactured in the city of Porto Alegre by BT Transmitters. The transmitter will be sited at the public broadcaster (EBC) Rodeador Park, near the capital Brasilia, to be connected to one of the huge HF antennas of EBC (National Amazon Radio is transmitted from there).

The equipment (a transmitter of 2.5 kW) will be tested on an experimental and scientific basis with the help of the University of Brasilia (UnB) and the Ministry of Science, Technology and Innovation.

The National Radio of the Amazon broadcasts from Brasilia especially to the Northern, Amazonian region of Brazil. The signal will be also available in the neighbouring countries to the north of Brazil. This is primarily a domestic shortwave digital project aimed at the Amazon where about 7 million riverside and indigenous people live. They are far from any other means of communication as there is no mobile phone or internet coverage.

Rafael Diniz, the Chair of the DRM Brazilian Platform, thinks that: “Shortwave digital radio (DRM) for the Amazon region will ensure a new level of communication and information as Nacional’s programming is both popular and educational. It brings audio and much more at low energy cost to whole communities there. With the adoption of digital radio, one of the major problems, that of poor sound quality affecting at times shortwave, will end. Listeners will be able to enjoy DRM broadcasts in short wave with a quality similar to that of a local FM station together with textual and visual multimedia content.”

“This is a huge step forward, says Ruxandra Obreja, DRM Consortium Chair, “not just for Brazil but for the whole of Latin America. When everything else fails or does not exist, DRM will provide information, education, emergency warning and entertainment at reduced energy costs.”

As a side note, I do hope the DRM Consortium or the University of Brasilia and the Ministry of Science, Technology and Innovation somehow make DRM receivers available to the “7 million riverside and indigenous people” they hope will eventually benefit from their broadcasts. At this point, however, this sounds more like a university experiment similar to those conducted at the Budapest University of Technology in Hungary.

Brazil proposes end of all amateur radio exams (Southgate ARC)

ANATEL, the Brazilian National Telecommunications Agency, recently published a public consultation, CP65, which is available at this link:

In their website, LABRE, the Brazilian Amateur Radio League, was surprised by the CP65 proposal that proposes, among other topics, the extinction of the COER (amateur radio certificate) exam for all classes and replacement by free access to initial class C, as is done today with the Citizen’s Band, as well as access to subsequent classes B and A upon presentation of the Certificate of Technical Course and Graduation in Telecommunications, respectively, or minimum stay of 3 years in each class.

In addition, the aforementioned proposal suggests ending the rules of different prefixes for each of the States of the Federation, remaining only the prefix per class and there would no longer be any special callsigns.

The proposal, in addition to going against what is consensus in the international regulation related to the Amateur Radio Service, is absolutely contrary to the LABRE’s thinking with regard to the minimum requirements to be a radio amateur and also does not match ANATEL’s request for support from LABRE in the revision of amateur radio regulations in Brazil.

For further clarification on the subject, LABRE has already requested a meeting with ANATEL, which will be scheduled soon.

Radio Engineer Files Objection to WIPE (DRMNA.info)

Story by Bennett Kobb:
On September 3, radio engineer Alex Pilosov of Shortwave Solutions filed with the FCC an objection to WIPE, the DRM-based HF station of Turms Tech of New York, presumed to be ready to broadcast from the Armstrong Tower in Alpine, NJ.

WIPE is suspected to be intended mainly for secret, non-broadcast message transmission for private trading clients while broadcasting financial and economic news for the public.

WIPE is not yet operational. The station is waiting on its FCC license, but Pilosov took aim at possible glitches in its license application. He also raises the issue of whether U.S. shortwave stations can legally conduct non-public telecommunications in the broadcast bands in a service limited to broadcasting.

Pilosov is a consultant to HF stations in the Experimental Radio Service, which are not constrained by the broadcast rules; thus he or his clients are prospective competitors to WIPE. This is Pilosov’s second FCC objection. He also filed against the application of Parable Broadcasting for WPBC, a DRM HF station proposed for Batavia, IL.[]

Radio in the Malvinas War (RAE)

In 2020 we celebrate the centenary of radio in Argentina. Such an event can be approached in various ways, since there are several milestones along this century of radio in our country. There are some events that are marked by fire in collective memory.

It is our intention to approach the celebration focusing on an event in which radio was in the spotlight: the 1982 Malvinas War, a conflict waged on various fields: military, economic, diplomatic and, of course, communications, mainly as a means of propaganda.

Most countries over time have recognised the great potential of radio as an effective instrument both in times of war and peace. Historically, Germany was the first country to use this for purely political purposes.

During WWII the broadcasts of Radio Tokyo, Radio Germany, the BBC in London and other stations were used for propaganda and military purposes by combatant nations.

The post-war period and the subsequent Cold War brought along a “war of the airwaves”. During these years, countless stations emerged with their own propaganda styles, looking to advance their social, political and economic systems.

An example of this are the broadcasts of Radio Moscow, Voice of America or Radio Beijing. Along with these stations, others of a clearly political nature emerged, such as Radio Free Europe and Radio Liberty, that targeted countries in Eastern Europe, as well as nations that became independent after the collapse of the Soviet Union. This group also includes the so-called clandestine stations, which generally broadcast secretly from conflict zones or from nearby regions or using rented transmission sites.

Before April 2, 1982, the Malvinas Islands had one radio station: the Falkland Islands Radio Service (FIBS) – with broadcasts in English. Content aired included locally-produced programs as well as news services of BBC London. It broadcast on 536 khz and 2370 khz.

The AM frequency was intended to cover the Port Stanley area, reaching a little further with SW transmissions.[]

Guest Post: Brazil’s newly-formed “15.61 Crew”

Many thanks to SWLing Post contributor, Martin Butera, who shares the following announcement for a new radio enthusiast group in Brazil:


The new 15 point 61 Crew

São Paulo is the largest city in Brazil, the Americas, and the seventh largest in the world, with a population of 11,300,000.

 

This was the stage for the meeting between Ivan Dias da Silva Junior (a recognized Brazilian radio listener with more than 27 years of experience and founder of the Regional DX) and his colleague, Martin Butera (a renowned amateur radio operator (LU9EFO – PT2ZDX), with 29 years of experience and currently a correspondent journalist for the British Dx Club, covering information from South America for the radio newsletter “Communication”).

The place of the meeting was not an accidental: we met in a noted coffee bar in the Republic Square–an iconic meeting point in São Paulo. Republic Square is located in the city center and is one of the most visited places in Brazil.

We founded the 15 point  61 Crew in São Paulo, on September 3, 2019.

The 15 point  61 Crew is not a DX club, nor a formal registered organization. We are just an informal group who like DXing.

What is the meaning behind our name? The number 15 is the dialing code of Sorocaba and  61 is the Brasília code, joining the two cities where the Crew founders are based–a distance of more than 900 km (Brazil is a huge country!).

The 15.61 Crew doesn’t have political or religious objectives. Our main objective is DXing, with an emphasis on organizing related activities: mainly DXcamps to be held in distant and exotic places, and bringing a new panorama of what is shared about DXing in our country.

We don’t have any kind of administration positions. The 15.61 Crew members are and always will be in equals.

To be a member of 15.61 Crew you just need to be active in our hobby, share information, write items, go with us to DXcamps, develop technical projects, etc.

As we aren’t a DXing club or organization, we will not have a website nor social media. We will share micro-books, especially about our activities through existing media, like the SWLing Post by our friend, Thomas Witherspoon, and by ourselves, because at the moment we are members of other radio related bulletin boards.

Our communication will be through an email address and a Paypal account for those who want to help us to continue developing our activities and also provide feedback on other projects (such as sharing content with other websites, thus creating a virtual collaboration for all).

For this purpose, we are currently developing several projects, such as a 15.61 Crew certificate program and different materials, such as caps, shirts, mugs, etc.

The 15.61 Crew members believe that there are so much things to be heard in the ether and we are prepared for it.

Ivan Dias da Silva Junior & Martin Butera

(15.61 Crew founders)

São Paulo, September 3, 2019


Thank you for sharing this Martin! I hope the 15.61 Crew enjoys some great success and champions a dynamic DX community! If you’re interested in joining this South American crew, contact Martin Butera.

Oxford Shortwave Log: DXing in the tropical rainforest of Pará, Brazil – part 2

img_9956pl-680

Hi there, here is part 2 of my reception videos taken in the tropical rainforest of Pará, Northern Brazil. As I mentioned in my previous post, I took a Tecsun PL-680 with me on the trip because I didn’t want to risk losing or trashing one of my precious vintage portables but also because of the following:

  • It can handle a longwire very well without overloading (I actually only used a 5 metre wire)
  • An excellent synchronous detection circuit and audio bandwidth filtering options
  • Excellent sensitivity, as demonstrated by the many DX reception videos on YouTube
  • If it got lost or damaged it would be a pain, but not difficult to replace

So, what can you hear in the jungle? Part 2 of my group of reception videos follow below – I hope you enjoy them.

Brazilian DX heard in Oxford UK, with venerable Sony ICF-2001D

Hi there, I thought I would share some Brazilian shortwave catches with you, obtained using my Sony ICF-2001D receiver and 200 metre experimental longwire. The first is Radio Bandeirantes, Sao Paolo on 9645.4 kHz. This is a station that I’ve only heard once or twice previously, but was received with excellent signal clarity and strength recently, using my deployable longwire antenna. I would rate this station as moderately difficult to receive with reasonable discernibility. The second is Radio Novo Tempo from Campo Grande, on 4894.9 kHz. This station I would rate as difficult to hear with discernible audio. The key is always signal-to-noise, thus moving yourself out of the ubiquitous blanket of QRM most modern environments endure will usually achieve this and of course coupled with sufficient space outdoors to erect a larger antenna will hopefully also improve signal strength. My final video on this post is Radio Nacional Brazilia on 6180 kHz. I would regard this station as quite easy to hear well; their effective TX power towards Europe is around 2 MW, however, outdoors, this station can literally boom in, with what might be perceived as local-AM signal strength. I hope you enjoy watching the videos and seeing/ hearing what’s possible with a modest set-up. As for the Sony ICF-2001D? Well the design is more than 30 years old, but in my opinion at least, still one of the very best portable shortwave receivers ever manufactured. Thanks and 73.

Shortwave Radio Recordings: Rádio Nacional da Amazônia

Rio_de_JaneiroLast night, Rádio Nacional da Amazônia had a booming signal into North America on 11,780 kHz. Rádio Nacional’s AM signal was very wide; I actually opened up the filter on my SDR to 16 kHz to record this broadcast. In truth, that’s probably too wide, but it certainly made for great audio fidelity.

So, if you’re in the mood for some Brazilian music and commentary today, this 168 minute recording of Rádio Nacional da Amazônia should satisfy.

This was recorded on Sunday, April 28–starting around 22:15 UTC–on 11.78 MHz. Click here to download the full recording as an MP3 file, or listen in the embedded player below:
