The International Amateur Radio union (IARU) was formed on this day in 1925.

 A celebration of how amateur radio has been serving people for over 100 years.

With over 3 million radio amateurs worldwide this day is the perfect time to tune in and connect with fellow hobbyists.

Date: Monday April 18, 2022

Time : All Day

This year’s theme is “Celebrating Amateur Radio’s Contribution to Society” 

Every year on April 18, Radio Amateurs worldwide take to the airwaves in celebration of Amateur Radio.

The theme of World Amateur Radio Day (WARD) is celebrating Amateur Radio’s Contribution to Society which is incredibly relevant given the isolation and need for communication as we enter a 2nd year living with the global pandemic.

As we have mentioned previously the increase in interest in amateur radio during the pandemic was significant with many amateurs supporting each other by creating nets or on line meet ups.

The team at Tecsun radios Australia have been humbled to see a rise in interest and participation in shortwave radio.

We celebrate how shortwave began. Here is a brief history:

Amateur Radio experimenters were the first to discover that the short wave spectrum — far from being a wasteland — could support worldwide propagation. In the rush to use these shorter wavelengths, Amateur Radio was “in grave danger of being pushed aside,” the IARU’s history has noted. Amateur Radio pioneers met in Paris in 1925 and created the IARU to support Amateur Radio worldwide.

Just two years later, at the International Radiotelegraph Conference, Amateur Radio gained the allocations still recognized today — 160, 80, 40, 20, and 10 meters. Since its founding, the IARU has worked tirelessly to defend and expand the frequency allocations for Amateur Radio. Thanks to the support of enlightened administrations in every part of the globe, radio amateurs are now able to experiment and communicate in frequency bands strategically located throughout the radio spectrum. From the 25 countries that formed the IARU in 1925, the IARU has grown to include 160 member-societies in three regions. IARU Region 1 includes Europe, Africa, the Middle East, and Northern Asia. Region 2 covers the Americas, and Region 3 is comprised of Australia, New Zealand, the Pacific island nations, and most of Asia. The International Telecommunication Union (ITU) has recognized the IARU as representing the interests of Amateur Radio.

This fantastic pack broadens your listening to the digital radio world allowing you to both listen to shortwave and ​​receive and decode DRM Shortwave Radio signals

Finally, a stand-alone Digital Radio Mondiale (DRM) Shortwave Radio has arrived and is available for DRM and shortwave radio enthusiasts to add to their collection.

The TRA Q-3061 DRM Shortwave Radio has been a long time coming and after evaluating dozens of samples over the years we have finally found a stand-alone desktop DRM radio that is suitable for Australian, New Zealand, and Pacific Islands listeners.

The TRA Q-3061 DRM Shortwave Radio is primarily designed to receive and decode DRM Shortwave Radio signals but the radio can also be used to receive traditional Shortwave (AM) broadcasts, FM, and AM (MW) broadcasts. The Tecsun Radios Australia Q-3061 DRM Shortwave Radio receives DRM, FM, and Shortwave (AW) signals via the inbuilt telescopic antenna, or for superior reception, the radio provides two dedicated external antenna BNC connections for DRM, Shortwave (AM), FM, and AM (MW) signals. On the FM band, this receiver also decodes RDS where broadcast. In slow tuning mode, the frequency step is reduced to 1 kHz. This is an advantage when tuning the extended MW band (530-1710 kHz) to receive specialised broadcasters in Australia.

The TRA Q-3061 DRM Shortwave Radio is for experienced shortwave users. There is a limited number of DRM signals available in our region although the total number of DRM broadcasts are increasing. This radio is squarely aimed at radio enthusiasts and DXers, most signals require an external antenna, experience, and patience.Included in this pack is the reception boosting Tecsun Shortwave and AM Outdoor Antenna which significantly enhances the reception of signals in the medium wave (AM) and shortwave antenna bands covering 0.5-30 MHz. The Tecsun Shortwave and AM Outdoor Antenna is based on a long wire antenna design but provides significantly improved reception over a long wire because the Tecsun Shortwave and AM Outdoor Antenna utilises a matching transformer that acts as a balun with a ratio of 10:1.

DRM radio over the AMAZON

The People of the Amazon will soon be covered by DRM shortwave as National Radio of the Amazon orders a 100 kW BT transmitter

The vast area of the Amazon known as the Amazon Rainforest is the largest tropical ecosystem in the world, with rainforest covering roughly 40% of South America, stretching over ten countries in South America, and is almost as large as the United States! The rainforest is home to both large and small communities in very remote areas, some harvesting crops along the rivers and others in more secluded villages deep within the forests.

As you can imagine communication to these areas can be difficult so it was no surprise when at the end of last year, testing of DRM technology began using a transmitter of 2.5 kW with the digital power of just 1 kW.

Despite this low power of the transmitter supplied by BT Transmitters, recordings were reported from different regions of the country and even from North America and Europe.

As a result of these tests, the National Radio of the Amazon decided to use DRM shortwave transmissions to serve indigenous populations in the northern Amazon region.

At the sizable cost of $650,000 USD. Public broadcaster Empresa Brasil de Comunicação (EBC) ordered a 100 kW BT transmitter to broadcast in DRM at 11,780 kHz in the 25-meter band, an existing shortwave channel used by Rádio Nacional da Amazônia.

This is considered to be the first domestic DRM installation on a locally produced transmitter in Latin America.

DRM radio

After many years of stagnation, DRM is emerging as a perfect fit for shortwave broadcasters seeking to increase their audience, and at the same time reducing their energy consumption.

DRM is an open source, non proprietary standard for terrestrial broadcasting, promoted by the DRM Consortium, a group of transmission equipment and receiver manufacturers as well as international broadcasters.

Over 30 broadcasters from around the world now carry DRM broadcasts. The latest schedule can be found here: http://www.hfcc.org/drm/

To receive DRM broadcasts a suitable receiver is required. The GR216 receiver, https://www.tecsunradios.com.au/store/product/tecsun-drm-radio/, promoted by Tecsun Radios Australia is a high-performance receiver, both on DRM and analogue shortwave. It is a self-contained unit, with provision for the connection of external antennas for shortwave and FM.

The receiver includes a self contained linear power supply which eliminates interference caused in  receivers powered by switch mode power supplies.

We recommend an external antenna for good DRM reception and our MW/SW Outdoor Antenna  https://www.tecsunradios.com.au/store/product/tecsun-shortwave-outdoor-antenna/ is most suitable. This antenna incorporates a 9:1 balun to provide the correct impedance for most shortwave receivers with an external antenna socket.

The typical improvement over the same length of wire without the matching components is between 10 and 15dB in signal level.

A word about antennas:

Directional characteristics of random wire and long wire shortwave receiving antennas are dependent upon the antenna length, height above ground, received frequency and directional orientation of the antenna wire. The four elements are interactive.

Generally the antenna should be aimed so that the transmission source is at 90 degrees to the antenna. So if the transmission source is to the West, run the antenna on a North South direction if possible. This works best on antennas that are less than a quarter wavelength in length and mounted a quarter wavelength above the ground (such as the antenna mentioned above).

In the case of a simple longwire without matching, the length of the wire cut for one quarter wavelength at popular DRM frequencies is as follows:

13Mhz: 6 metres in length, 15Mhz: 5 metres in length, 7 Mhz: 10 metres in length

A simple long wire antenna will work better at greater elevation above the ground, ie the higher the better. Multistrand insulated wire will work better and for longer that solid copper wire, which will weaken with repeated movement.

In practical terms, a DRM receiver with an external antenna will be able to hear most current DRM broadcasts from 13-18Mhz. Check the broadcasting schedule for the appropriate times.

Remember that all times are given in GMT and that means AEST (Australian Eastern Standard Time) is 10 hours ahead of GMT. Hence (for example) the BBC Relay from Singapore on 15620Khz will appear between 2pm and 8pm AEST.

One more factor that can influence the success of your reception is the direction in which the signal is being beamed.

This information is also available on the DRM HF schedule site. If you are in the target area you will have a much better chance of sucessfully receiving DRM broadcasts.

Target areas can be seen here: https://www.drm.org/what-can-i-hear/broadcast-schedule-2/

There are many stations that can be received if suitable attention is paid to antenna orientation, and broadcasting schedules, with more stations being added to the schedule every month.

Good Listening !
