New updates for SDR#, libairspyhf and Airspy HF+ (Discovery) Firmware

Airspy has announced the latest releases of SDR# r1702, libairspyhf r1.5.0 and Airspy HF+ Firmware r2.4.0. 

Here's a summary of the changes:

The FM Stereo flag was added in the SDR# API: FmPilotIsDetected.

A new experimental Low-IF mode at a lower sample rate (256ksps IQ) was added across the chain to allow portable devices to operate smoothly without requiring further DC/IQ correction or frequency translation. This mode is considered "experimental" because the AGC has yet to be optimized to accommodate for the smaller bandwidth, but it is already usable as-is with the AGC always on. 

For the curious types, 256ksps Low-IF was obtained by shifting the IF, adding a narrower channel filter and decimating 768ksps by 3. This gives a wonderful number that is a multiple of a known sound card standard rate: 32kHz.

The IQ streaming and command handling were optimized to allow all of this processing to happen. A positive side effect is that the streaming is no longer interrupted by the commands (set frequency, gain, etc.) - and this one is not experimental.

Emergency Warning Functionality on DRM Digital Radio for Saving Lives

Six-hundred-and-seventeen (617) lakh people in the world were impacted by disasters in 2018. Extreme weather conditions accounted for majority of people affected by these disasters. Unfortunately, India is also being affected by disasters a number of times. But extreme weather conditions often come with a pre-warning phase. The questions is – Are we getting the most out of this time window to warn the public and save lives?

USAGM networks recognized for excellence with Edward R. Murrow Awards

WASHINGTON, D.C. - Two U.S. Agency for Global Media (USAGM) networks-Radio Free Europe/Radio Liberty (RFE/RL) and Radio Free Asia (RFA)-have been named winners of the prestigious 2019 National Murrow Awards. This is the first time the two networks have received this honor, presented by the Radio Television Digital News Association (RTDNA) for excellence in electronic journalism.

"I am thrilled that the RTDNA's Edward R. Murrow Awards have recognized the high-caliber reporting that RFE/RL and RFA produce," said USAGM CEO John F. Lansing. "My heartfelt congratulations go to the skillful journalists and storytellers who offer our global audiences accurate and professional journalism-the bedrock of what we do at USAGM."

CEO Lansing added, "Edward R. Murrow, who in the early 1960s led the U.S. Information Agency, a predecessor to USAGM, would be proud of our modern media organization's wide-reaching impact."

Daisy Sindelar, Acting President of RFE/RL, and Libby Liu, President of RFA, offered praise for their award-winning networks, which provide compelling, uncensored and locally-oriented news and information to audiences in some of the harshest media environments around the world.

"We are honored to receive this recognition for providing our audiences with unique stories, powerfully told, on the most influential formats in our coverage area," said Sindelar.

RFE/RL received the National Murrow Awards' top honor for Multimedia in the Television Network category. Judges reviewed eleven examples of RFE/RL's impressive domestic news coverage ranging from Armenia to Uzbekistan.

RFA Mandarin's "The Women Against the State" won in the juried contest's Excellence in Video category. The piece focuses on the aftermath of China's "709 crackdown"- a nationwide roundup of lawyers and legal activists that began in July 2015 - and the wives of those still held in custody today.

"RFA Mandarin's digital team deserves full credit for this prestigious award. Their hard work to spotlight these brave individuals and share their stories speaks to Radio Free Asia's critical journalistic mission," said Liu.

Although this marks the first time that RFA has won a National Murrow Award, the network won several Regional Murrow Awards in years past.
The United States Agency for Global Media (USAGM) is an independent federal agency, supervising all U.S. government-supported, civilian international media, whose mission is to inform, engage and connect people around the world in support of freedom and democracy. USAGM networks include the Voice of America, Radio Free Europe/Radio Liberty, Office of Cuba Broadcasting (Radio and TV Marti), Radio Free Asia, and the Middle East Broadcasting Networks (Alhurra TV and Radio Sawa). USAGM programming has a measured audience of 345 million in more than 100 countries and in 60 languages.

DRM announces seminar during Broadcast Asia 18th June 2019

Digital Radio Mondiale (DRM) part of Broadcast Asia Seminar in Singapore

The Digital Radio Mondiale Consortium will participate in an extensive seminar on Digital Radio Implementation and Transition Strategy scheduled during Broadcast Asia, on June 18th in the morning. The half-day event will be held at Suntec Singapore, Level 3, Room 308.

The seminar aims to offer an understanding of DRM technology (and other standards), to examine the best strategies for a smooth transition to DRM while drawing on practical examples and the experience accumulated in Asia-Pacific and other parts of the world.

The DRM experts will present the standard, so versatile in the AM bands (like medium wave) and VHF bands (like FM), its benefits and many valuable features like the Emergency Warning Functionality. Network planning considerations, actual steps to be taken for a successful DRM roll-out and demonstrations of some of the excellent audio in DRM and other benefits will be part of this unique event held in conjunction with this major Broadcast Exhibition. The experts who will share their theoretical and practical knowledge with the participants are: Alexander Zink, Fraunhofer IIS, Albert Waal, RFmondial and Sharad Sadhu, Consultant.

Ruxandra Obreja, DRM Consortium Chair, says that: "This is the first time that ABU and AIBD have invited us to take part in such a comprehensive seminar. We are sure it will highlight the benefits of DRM by giving participants the chance to understand the features and benefits of the DRM digital standard in a simple and practical way. DRM is a great technology for the Asia-Pacific region and the more participants learn about it, the more comfortable they will be to ask for and introduce it."
