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.

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:

Shortwave Radio Recordings: Rádio Nacional da Amazônia

RadioNacionalDaAmazoniaThis past weekend, Radio Nacional da Amazonia had a booming signal into North America on 11,780 kHz. I recorded their broadcast throughout the night, assuming it would eventually fade; however, it did not.

So, if you’re in the mood for some Brazilian music and commentary today, this eight-hour recording of Radio Nacional da Amazonia should satisfy.

This was recorded on Sunday, January 6th–starting around 02:30 UTC–on 11.78 MHz. Click here to download the full recording as an MP3 file (276 MB!), or listen in the embedded player below:

Note to those subscribed to our podcast:
I was a bit reluctant to include a link to the podcast feed as this file is so large; I rarely make eight-hour recordings. I did offer it up, however, based on the fact that there are so many other podcasters who regularly serve up files in excess of 250 MB. If you believe this file is too large to be included as a podcast, please comment; I certainly don’t want to choke up your bandwidth or overwhelm your iPod!  But it’s wonderful listening.
