Gaston County resident Oscar Norris, also known by his call sign W4OXH, is turning 106 on Sept. 25.
Norris is not only the oldest living amateur radio operator in North Carolina, but according to information from the American Radio Relay League he is also the oldest living operator in the United States.
The Gaston County Amateur Radio Society and the Gaston Radio Club, both of which Norris is a long-time member, have come together to host a special airwave event for him from Sept. 20 – Oct. 1.
This event will honor Norris and his life, and will be hosted by operators in three different states, according to Gaston County Amateur Radio Society president Tony Jones.
Both on and off the air, Norris “is one of the most gentle and kind people,” a person could encounter in life, according to fellow amateur radio operator and friend, Mike Harvey. [Continue reading…]
Radio Taiwan International (Rti) celebrated its 95th anniversary with an event featuring remarks by Taiwan President Tsai Ing-wen on Tuesday. Additional speakers included Legislative Speaker You Si-kun, Ambassador of Saint Vincent and the Grenadines to Taiwan Andrea Bowman, and Rti Chairperson Cheryl Lai.
In her speech, President Tsai said that Rti has witnessed important events in the development of Taiwan’s democracy over its 95-year history. Tsai says Rti has carried out its responsibilities from then until now by continuing to cover Taiwan’s growing engagement with the world. Tsai also said Taiwan’s ability to connect people all over the world was demonstrated by the many postcards received in various languages on display at the event. She thanked Rti for its past work and says she hopes Rti will continue to bring the voices of Taiwan to the world.
Rti Chairperson Cheryl Lai also gave remarks at the event. Lai says Rti is Taiwan’s only public media company to broadcast in 20 languages across multiple platforms. Lai says Rti has been an important channel for people in Southeast Asian countries to understand Taiwan. She says the Indonesian, Vietnamese, and Thai language services have a long history at Rti, and are important resources for Taiwan’s new immigrants and migrant workers. Lai says that Taiwan also began a Ukrainian language social media service following the outbreak of the Russo-Ukrainian war. Lai concluded by saying that as Taiwan grows more vibrant and diverse, Rti will continue to spread Taiwan’s voices to all corners of the world.
Ambassador Bowman said in her speech that reaching 95 years of service is not an easy accomplishment to achieve. She says Rti represents an excellent model for how to spread the message of democracy and peace across the globe. [Read this article on the Rti website…]
It was 1923, and radio was the phenomenon of the day. Over 600 broadcast stations were on the air, and Americans bought 100,000 receivers that year. (Sales would jump to 1,500,000 in 1924.)
This new instant mass medium flashed news of important events around the country in minutes instead of days. In addition to news, tens of thousands tuned in to hear music and learn from lecturers holding forth on their areas of expertise. A few tried to make sense of broadcast guitar or swimming lessons.
Those without radios gathered in taverns and restaurants to listen to election returns and descriptions of baseball games.
New radio owners everywhere strung wire across their rooftops to make aerials, and then puzzled out how to connect a loudspeaker to the set, along with the A, B, and C batteries the setup required. (Soon enough, “house-current” radios would come along; most of the early ones were designed to draw power from fittings screwed into lamp sockets.)
Once the radios were set up, many owners hosted “radio parties” and danced to the latest jazz music with their friends.
At the same time, the game of Bridge was sweeping the country. It had been brought to New York from England in 1893. Here, as across the Atlantic, Bridge replaced the popular game of Whist as a top pastime, and quickly spread across the nation. [Continue reading…]

Many AM medium wave listeners are looking for solutions to improve the reception performance of their radios.
After many attempts, which I don’t want to entertain anyone with, a coupler was created that feeds the external antenna directly into the ferrite antenna. I use my 66 foot long wire antenna on 50 ohm RG-58 cable, but other antennas will have similar success.
The clips available on YouTube speak for themselves:
https://youtu.be/FIylJk3F9Xk?si=Kp7SowdUXI5i5QAV
https://youtu.be/RHAla9jPoi8?si=VoG3w274k08Ul8Q4
Experiments with smaller ferrites and antenna rods met with no success. It is important that the coupler still works even at a distance from the ferrite antenna and without precise alignment.
With tube radios it easily bridges the distance from the housing to the ferrite rod Antenna
The finished coupler consists of 6 NiZn ferrite cores, which are connected with glue to form a rod. 8 turns of wire are wound over this and soldered to an RG-58 cable. Some electrical isolation tape and ready. So far I’ve just put it in a box. Of course there are finer solutions and it should be protected against shock. Ferrite cores are notoriously brittle.
Here is a link to the ferrites used (purchased at AliExpress).
Advantages: Advantages to what? Nothing comparable exists.
So there are advantages to feeding via an antenna socket. The signal coupler is also good for radios without an antenna socket. But in case of using an antenna socket, common mode wave interference picked up in the house goes unlimited into the radio. Due to the magnetic coupling to the ferrite antenna, common mode waves are completely suppressed. They do not create a magnetic field in the coupler.
No changes are necessary in the radio
The biggest advantage is, that you can listen to distant stations loud and clear, which previously only produced a quiet scratching noise.
I very much welcome reports of experiences.

IBC Amsterdam 2023 – 16th September 2023 – DRM Consortium Showcase Event
CML Microcircuits (CML Micro) has announced at the IBC 2023 DRM Showcase Event, the full release of the world’s lowest-cost, lowest power, and smallest sized Digital Radio Mondiale (DRM) broadcast receiver module (DRM1000). DRM is the world’s leading digital radio broadcast standard able to provide rich, high quality digital content over vast areas using medium-wave (MW) and short-wave (SW). In addition to high-capacity local broadcasting at Very High Frequencies (VHF).
The DRM1000 is a complete ‘antenna to speaker’ module, containing all hardware, software, IP and patent licenses required for a radio equipment manufacturer to easily realize a dual mode (digital and analogue) DRM capable receiver.
The module offers a 60% cost reduction and 80% power reduction over existing DRM technologies in the market. The device can run effectively from solar or wind-up rechargeable batteries: in addition to small primary cells. Low power operation directly improves accessibility to vital educational and public digital radio services across many emerging nations and opens the great features of DRM to many millions of potential listeners around the world.
In offering the DRM1000, CML Micro wish to enable their customers to design a complete DRM /AM /FM broadcast receiver solution, which is attractive, highly featured and accessible for all. The module allows these innovative receivers to be manufactured locally in emerging nations in addition to traditional technology manufacturing locations.
In addition to announcing the availability of the DRM1000; CML Micro is also proud to announce that the device has been adopted by Gospell Digital Technology Ltd for two new DRM portable radio families to be shown for the first time at the IBC 2023 DRM Showcase Event.
Haochun Liu, Head of Research and Development at Gospell, said: “At Gospell, we’ve always held a steadfast belief in the pivotal role that the accessibility and ubiquity of DRM radios play in enabling people to access high-quality information. This unwavering commitment has driven us over the years to design and manufacture user friendly DRM receivers, constantly pushing the boundaries to make them more accessible and attainable for all. The introduction of the DRM1000 module, with its impressive low-power consumption, cost-effectiveness, and high performance, has been a game-changer. We are truly honored to collaborate with CML Micro in launching two groundbreaking DRM receivers based on the DRM1000 module, namely the GR-220 and GR-221. We’re confident that our combined efforts will not only deliver unparalleled value to people but also pave the way for the next chapter in DRM technology.”
One third of the world’s population remains without an internet connection. Many millions of people will benefit from widespread DRM adoption. Increasing access to DRM enhances public services in remote areas, or where an internet connection is very expensive. This includes a disaster and early warning service that can be used in the event of interruption to communications caused by natural disasters.
CML Micro’s VP of Global Marketing, Matthew Phillips, said: “The benefits of DRM are already being enjoyed by listeners in the Indian market with 70% of the population covered by DRM broadcast services and 6 million new cars already fitted with DRM capable receivers. We believe the market for DRM capable receivers is set for significant growth over the coming years. The DRM1000 provides an ideal platform to serve this emerging market with low cost, battery-powered portable receivers sold in millions of units.”
DRM in the medium-wave or short-wave band delivers FM-like quality to listeners spread over many thousands of square miles, from a single transmitter. This makes DRM the optimum digital radio solution for emerging nations. DRM uses existing long-, medium-, short-wave and very-high frequency (LW, MW, SW and VHF) radio frequency bands, operating seamlessly alongside current analogue services. [Continue reading…]

Fourier analysis. https://en.wikipedia.org/wiki/Fourier_analysis This can transform a serial data stream into a parallel data stream using a different frequency carrier for each path. For example a 16 level quadrature Amplitude modulated data stream at around 99.4 kbit/s is carried on 213 carriers in a channel 95 kHz wide using a transmission frequency between 47 – 230 MHz.
The Digital Radio Mondiale™ (DRM) Consortium has welcomed the decision by Indonesian authorities to adopt the globally recognised, open, and ITU-endorsed DRM Digital Radio Standard for national implementation in a country with a population exceeding a quarter of a billion.
The announcement was made during the DRM IBC Showcase event in Amsterdam. DRM is the only digital radio standard capable of meeting all coverage requirements for national and local public radio stations, as well as commercial and community broadcasters. Moving forward, DRM-based digital radio services will be available in the medium wave (MW) and FM bands, and also in VHF band-III, across all 18,000 of Indonesia’s islands.
Some 275 million Indonesians will soon benefit from a transformative radio experience featuring enhanced audio quality and, importantly, an additional layer of disaster protection via DRM’s Emergency Warning Functionality (EWF). The introduction of modern digital radio services is set to invigorate the entire radio ecosystem and broadcast industry, thereby stimulating both Indonesian and global receiver manufacturing.
The DRM Consortium is keen to continue its close collaboration with Indonesian broadcasters, stakeholder groups, governmental agencies, as well as the receiver, automotive, and mobile phone industries in Indonesia. This concerted effort aims to ensure the successful nationwide roll-out of DRM digital radio services, for the benefit of the entire Indonesian populace.
