“Due to the numerous requests from his Build-a-radio-in-5-minutes, radio amateur Tommy Helgevold OZ4KID decided to make a better video with explanations on how to make a radio like this

He also decided to beat his old challenge as well…

…so without further ado, I present to you – How to build a radio in less than 1 minute, can you build it?

There’s even a schematic in the end of the video + an animated version of the entire breadboard setup.

Thanks for watching, & enjoy.

HFCC Conference: “Shortwave remains essential”

ABU-logo(Source: Asia-Pacific Broadcasting Union)

“Short wave will continue to be an important part of broadcasting, a coordinating conference hosted by the ABU in Kuala Lumpur has been told.

The 10th Global Shortwave Co-ordination Conference of the High Frequency Coordination Conference (HFCC) with the ABU and the Arab States Broadcasting Union (ASBU) from 20-24 January 2014 is part of the regular twice-yearly seasonal management of shortwave frequencies around the globe to coordinate usage and minimise interference.

Mr Bassil Zoubi, Head of Transmission at ASBU, said: “Shortwave programs will continue to be vital in addressing and communicating with some important parts of the world, especially with Internet penetration in the Arab countries around 34% while in some other parts of the worlds it is less than 10%.”

He said the ASBU had adopted T-DAB+ as a delivery platform for regional audio broadcasting, though the union continued to support [shortwave] DRM as a important delivery medium for international as well as national coverage, which was why the ASBU was calling for a universal radio chipset.

HFCC Chairman Mr Oldrich Cip said shortwave radio was important for travellers and isolated people, and it reached across the digital divide to the most disadvantaged and marginalised societies.

The International Federation of Red Cross and Red Crescent Societies had underlined this role of wireless radio in the 2013 World Disaster Report.

“It said that marginalised populations may not have the money or the knowledge to take advantage of the digital revolution,” Mr Cip said. “The report has noted that with only six per cent of people in low-income countries using the Internet in 2011, the digital divide was still stark and therefore access to low cost media technology was really the key.”

He also urged the conference that effort was needed to ensure that terrestrial broadcasting was part of the framework of the Global Strategy for Disaster Risk Reduction.

ABU Director of technology Dr Amal Punchihewa reiterated the importance of ensuring there were mechanisms in place to deliver information technology to the most needy and vulnerable populations around the globe.

“The ABU will continue to work with our partners to ensure this technology will survive and thrive for the benefit of the population, in times of crisis, in areas of isolation and at the most vulnerable times,’ he said.

Mr Gary Stanley, Rapporteur of the HFCC Steering Board, thanked the ABU for hosting the conference and said shortwave radio was still very important for disseminating news and information to regions where Internet penetration was low and other ways of receiving international media were limited.”

(Source: NASWA press release)

NASWA, the North American Shortwave Association, has announced preliminary program details for its 27th Annual Winter SWL Festival to be held at the Doubletree Suites Hotel in Plymouth Meeting, Pennsylvania on March 14 and 15, 2014.

The Winter SWL Fest is the largest and longest-running annual meeting of shortwave radio enthusiasts and hobbyists in the Western Hemisphere. Beyond the opportunity to renew old friendships and make new contacts, the conference serves as a forum for discussion of radio-related matters of interest and import to the attendees, which have numbered in excess of 200 in some recent years.

This year’s program of forums features two presentations by Australian Mark Fahey, who has travelled North Korea extensively in recent years. Over four successive trips to each province of the country, he has smuggled in and out monitoring and recording equipment enabling the capture and analysis of hundreds of hours of domestic radio and television broadcasting.

Scheduled for successive afternoons on Friday and Saturday, Behind the Curtain: North Korean Broadcasting and Propaganda, will extensively discuss and feature audio and video examples of North Korean internal and external broadcasting, international and clandestine broadcasters that manage to penetrate through the regime’s jamming, as well as descriptions and photographs of the media infrastructure used by the North Korean regime as the prime instrument of control over the population.

In addition to the ever-popular annual forums on scanning and unlicensed broadcasting (otherwise known as pirate radio), the 2014 Fest program also will feature the following sessions and presenters (subject to revision):

Radio Broadcasting: The Earliest Years – Dr. Harold Cones
Navigating a Future for the Radio Hobby – Sheldon Harvey, President of the Canadian International DX Club
Internet Radio 2.0 – Rob DeSantos
A Practical Guide to Loop Antennas – Jef Eichner
Developing a Shortwave Radio Archive – Thomas Witherspoon, President of Ears to Our World
Whatever Happened to Digital Radio? – Mark Phillips
Ionosounders and Other Real Time Propagation Aids – Tracy Wood
Ham Radio Tools for SWLs – Skip Arey

There’s also David Goren’s Friday night Shortwave Shindig radio studio party, as well as brief talks by Paul Ladd on World Christian Broadcasting’s shortwave transmitter projects, Allen Loudell of WDEL radio on trends in U.S. commercial radio, especially news/talk radio; and Sheldon Harvey’s annual tribute to those who departed us for a “higher station” over the last year. Not to mention: the Saturday night banquet and Grande Raffle!

The CBC: A truly “wireless” transfer of money

On The Morning Edition, CBC Kitchener-Waterloo was able to successfully transmit bitcoin over radio waves.

This makes what is believed to be the first known transmission of the digital currency by a public radio station.

A series of beeps were played over the air, and listeners were asked to use an app known as chirp.io to decipher a code produced by the sound.

Chris Skory of Rockland County, New York was the winning recipient, and unlocked 0.05 bitcoin worth about $40. The bitcoin was donated by Waterloo start-up Tinkercoin and a local bitcoin enthusiast.

“I did not think that I was going to get it at all,” said Skory. “I figured there was going to be some pretty stiff competition out there.”

Perhaps we should challenge VOA Radiogram‘s Kim Elliott to perform an international wireless transfer via shortwave?  🙂 Certainly be a great plot to attract listeners!

Video: Build your own SDR

(Source: HamRadioNow via the Southgate ARC)

“Need that title decoded? MDSR = Modulator/Demodulator Software Radio. DIY = Do It Yourself (DOH! I knew that), and SDR… can you guess? Yes! Software Defined Radio. OK?

So, in this episode, Alex Schwarz VE7DXW will tell you about doing SDR on the cheap, using stuff you already have (a conventional SSB radio and your computer), plus their inexpensive interface. You pull RF out of your radio’s IF (some are easier to get into than others), run it thru their board, and into your computer for demodulation, filters… all the usual SDR stuff. And they’re just introducing the Transmit side of the equation.
