Historic Trans-Atlantic VHF Contact Made

Historic trans-Atlantic contact made on 144 MHz

A historic contact was made on Sunday the 16th June 2019 when the Atlantic was spanned for the first time on 144 MHz.

D41CV on Cape Verde Islands off the coast of Africa managed to work FG8OJ in Guadeloupe on 144.174 MHz using the FT8 digital mode.
The distance was an incredible 3,867 kms.

To put that into context, the distance from the west coast of Ireland to Newfoundland is 3,000 kms.

Tropo prediction maps show a path right across the Atlantic and suggest that even more incredble contacts may be possible.

Radio World: Koode Radio Aims to Reduce Conflict in Africa

ABUJA, Nigeria — Koode Radio International, a new shortwave program with considerable goals, has begun broadcasting to much of Western Africa.

With programs in the Fulani (or Fula) language, KRI aims to “educate, enlighten and entertain” its listeners, the Fulbe people. This predominantly Muslim, nomadic herder and farmer group is spread across Africa from Senegal in the west to Lake Chad in the east. Dialects of the language are spoken in some 20 countries and the station chose the name “Koode” because it means “star” in all of the dialects.

While some Fulbe are able to communicate via the likes of WhatsApp and Facebook, others cannot. Because a number of Fulbe are herders, they are not only beyond the range of the internet, but beyond the range of electricity.[…]

United Nations: Radio still a powerful worldwide tool for ‘dialogue, tolerance and peace’

“Even in today’s world of digital communications, radio reaches more people than any other media platform” explained the UN chief, adding that it “conveys vital information and raises awareness on important issues”.

“And it is a personal, interactive platform where people can air their views, concerns, and grievances” he added, noting that radio “can create a community”.

UN Radio was established on 13 February 1946, and since 2013, the day has been commemorated to recognize radio as a powerful communication tool and a low-cost medium.

“For the United Nations, especially our peacekeeping operations, radio is a vital way of informing, reuniting and empowering people affected by war”, said Mr. Guterres.

Despite the rise of the internet, many parts of the world, especially remote and vulnerable communities, have no access, making radio broadcasting via transmitters, a vital lifeline. Joining a community of local listeners, also provides a platform for public discussion, irrespective of education levels.

Moreover, it has a strong and specific role in emergency communication and disaster relief.

“On this World Radio Day, let us recognize the power of radio to promote dialogue, tolerance and peace”, concluded the Secretary-General.

Radio still sparking ‘new conversations’

The UN Educational, Scientific and Cultural Organization (UNESCO) underscored “the unique, far-reaching power of radio to broaden our horizons and build more harmonious societies”.

“Radio stations from major international networks to community broadcasters today remember the importance of radio in stimulating public debate, increasing civic engagement and inspiring mutual understanding”, UNESCO Director-General Audrey Azoulay said in her message.

Since its invention as the first wireless communication medium well over a hundred years ago, “radio has sparked new conversations and broadcast new ideas into people’s homes, villages, universities, hospitals and workplaces,” she continued. “To this day, dialogue across the airwaves can offer an antidote to the negativity that sometimes seem to predominate online, which is why UNESCO works across the world to improve the plurality and diversity of radio stations”.

The UNESCO chief pointed out that radio has adapted to 21st century changes and offers new ways to participate in conversations that matter, retaining its role as “one of the most reactive, engaging media there is”, especially for the most disadvantaged.

For example, she flagged that rural women constitute one of the most under-represented groups in the media and are twice as likely as men to be illiterate, “so radio can be a critical lifeline to express themselves and access information”.

Ms. Azoulay made clear that “UNESCO provides support to radio stations in sub-Saharan Africa that enable women to participate in public debate, including on often-neglected issues such as forced marriage, girls’ education or childcare”.

Linguistic diversity, and people’s right to express themselves on-air in their own languages, is also crucial – especially true in 2019 which has been designated by the International Year of Indigenous Languages by the UN.“In former conflict zones, radio can dispel fear and present the human face of former foes”, she elaborated, citing North-West Colombia where community radios are healing old wounds “by highlighting the good deeds of demobilized combatants, such as clearing polluted waterways”.

Around the world, the “inclusion of diverse populations makes societies more resilient, more open and more peaceful”, Ms. Azoulay spelled out.

“The challenges we face – whether they be climate change, conflict or the rise in divisive views – increasingly depend on our ability to speak to each other and find common solutions”, she concluded.

US Navy finds ham radio training makes “workers better at their jobs”

Can learning amateur radio make for better engineers and software developers?

Writing in C4ISRNET – Electronic Warfare, Eric Tegler says:

When a group of [US] Navy engineers and software developers took time away from their day jobs in December, they spent the time pursuing a task long considered passe: they became licensed amateur radio operators.

Some 23 employees from Naval Air Warfare Center Weapons Division (NAWCWD) took a week-long class in amateur radio at Point Mugu, California culminating with an FCC amateur radio license test. All passed and are certified at the “technician” level for amateur radio operation [permitted 200 watts on some HF bands, 1500 watts above 30 MHz].

Now, Navy officials say the move may make the workers better at their jobs. The staff gained an understanding of radio frequency (RF) propagation that’s essential to what they do, said Brian Hill, electromagnetic maneuver warfare experimentation lead and collaborative electronic warfare supervisor at NAWCWD.

Hill, who earned his amateur radio license in high school, noticed that while most of his department’s recent hires had degrees in computer science, many had little background in RF theory or operation.

“You can explain antenna patterns and concepts like omni-directional vs directional using Smith charts, but it’s helpful to add a demonstration to really convey the concept,” Hill said. “You can explain modulation as a concept, but for a demo… let them listen to how modulated digital signals with audio frequencies sound… For those who never knew the joy of hearing a 2400 bps modem connect over a telephone line, it was a new concept!”

These concepts are central to electromagnetic maneuver warfare.

“We need to be able to have awareness of all threats and opportunities from [zero frequency] to light within an integrated system,” Hill said. “Our adversaries are looking at the entire spectrum to use against us, and we need to do the same. Having awareness of how the atmosphere changes from daylight to night and how that affects propagation of [high frequency] is important.”

This can be critical for young developers/engineers whose experience is typically limited to the UHF/EHF-based systems now in vogue across communications, guidance and ISR technologies.
