A9100IARU (Special Event) - Bahrain

IARU celebrates its centenary in 2025. Since its founding in Paris, France, IARU has worked tirelessly to promote innovation in amateur radio and to encourage the growth of the service in communities throughout the world.

IARU has represented the Amateur Services at international and regional regulatory bodies by relying on our volunteers who come from many countries and communities. IARU has been a sector member of the ITU since 1932 and the work of our volunteers has continued since that date with unmatched success; as was highlighted with the accomplishments at WRC-23.

Bahrain Amateur Radio Society (BARS) is joining the IARU members celebration of the 100 anniversary.

The National Radio Day History
Nikola Tesla is said to have shown radio around 1893, even though Gugliemo Marconi is usually credited with creating it in the 1890s. Nevertheless, the process took decades, and numerous scientists made modest but important advances in our knowledge of radio waves, electric conduction, and electromagnetic induction. For instance, in the 1880s, Heinrich Rudolph Hertz made the discovery of radio waves, which contributed to the validation of James Clerk Maxwell's electromagnetic hypothesis from 1873.

It took a while for the technology to be used for communication after the invention of the radio. This was due to the fact that many more components were required in order to transmit and detect electrical waves, as well as the fact that the inventors were not yet aware of the useful and transformative potential of their creation.

Lee de Forest is credited as being the creator of public radio programming. In 1910, he presented the first public radio program featuring opera stars' voices. The first commercial radios that could receive a signal from a great distance were produced by De Forest's Radio Telephone Company.

Clearly, radio had a significant impact on music and quickly altered the nature of the business. Radio presenters could swiftly go on air to convey the day's events to a large audience. News also made its way to the medium. August 31, 1920, saw the broadcast of the first radio news program from Detroit, at a station that is still in operation today as WWJ. Radio was also employed for telephone services, sports programming, and even aviation navigation in the early 20th century.

Radio evolved and adapted with the digital revolution and the wireless era. Even while radio is employed for many different purposes these days, it no longer occupies the top spot in news and entertainment media. Radio finds it difficult to compete in that sphere with television, the internet, and other media, but people still adore it, and it doesn't seem like it will disappear anytime soon. In fact, because of its historical appeal, we now value radio even more.

Many devoted, excellent animals are in shelters all across the world, waiting for their permanent homes. If consumers keep purchasing from pet shops or breeders, many will never find one.

For a variety of reasons, adopting from a shelter makes sense.

An animal who is homeless and finds a lovely new home would love you without conditions. This has repeatedly been observed. When given a second chance at life, rescued animals show loyalty and love to their new family members.

You finally contribute to lifesaving. When you adopt from a shelter, you assist to save the animal you adopt and create space for another animal to receive the care they require to have their own happy ending.

Act heroically. Adopt a shelter animal right now and go beyond breed.

The K4QCD Dually is two antennas wrapped up into one package. On one side you have an End Fed Half Wave with a 49:1 transformer. Flip it over and on the other side is an End Fed Random Wire antenna with a 9:1 transformer. The dual transformer concept is the best of both worlds. Out in the field you can go either way with the type of antenna you wish to deploy, the only difference is the length of wire that you hook up to it. ~KB9VBR

At dawn and darkness, when other kinds of ionospheric propagation could not be expected to offer signal routes of these distances, a type of radio signal propagation known as gray line propagation can occasionally provide unusually long-distance radio communications.

Grey line propagation is only present at dawn and dusk, hence round-the-clock worldwide radio communications are not possible with it.

As such, radio amateurs and a select few others who can work around the timing and other constraints of its availability tend to be the main users of grey line propagation.
