We came across a story this month that reminded us of the importance of being educated in radio communication and a reminder of what a resourceful,  knowledgeable, and helpful community amateur radio operators are.

On September 7, 2022, a boat named  SV Nereida traveling from ​​Cape Flattery, the northwesternmost point of the USA to San Francisco, California became disabled after 2 days of 35 knot winds and storms. 

81 year old Jan Socrates, an experienced sailor who has sailed around the world without assistance, and in fact has been the oldest person to do so, found herself very low on power and her onboard radio equipment marginally operational. But her knowledge of amateur meant she knew how to get her message out to a community who could help!

Amateur operators in New Mexico, California, and Canada, and members of Group 7.155 heard her requests for assistance.

One such person who heard her request and in fact was able to contact Socrates on 40 metres was Gil Gray, N2GG. “Her power was extremely low, and she was unable to communicate on 14.300 MHz to notify the monitoring group on that frequency,” said Gray. “She needed help with wind and sea conditions, and tidal data for San Francisco Bay,” he added.

Q5 copy was almost impossible due to the low-power output on the HF radio which would typically be Q2 or Q3. Thankfully several software-defined radio (SDR) operators were on hand  in California, Utah, and Maui, Hawaii, who were able to glean enough copy to understand her situation and answer questions for her navigation.

Another stroke of luck was that several of these radio operators were also experienced sailors and helped guide Socrates through periodic contact with weather and wind reports.

Their last contact was on Monday, September 12, at 11:00 AM (MSDT). By this time, Socrates was sailing with only the forward sail on her 38-foot sloop. Thankfully, a “following wind” kept her moving without a mainsail. 

As the Golden Gate Bridge appeared within sight, Socrates was able to use the tidal information passed on by amateur radio operators to make it safely to Berkeley Marina in San Francisco Bay.

“I wouldn’t call it a rescue,” said Socrates, “just good amateur radio assistance — and I’m grateful for their help.”

This is actually one of 3 events in September in which amateur radio was able to provide emergency assistance.

If you would like to learn more about Jan Socrates’ travels, take a look at her Facebook page.

Emergency radio donations for Byron

As the Bureau Of Meteorology  declares another La Niña, increasing flood risk for the third year in a row, we reflect on those affected by this weather pattern last year.

Something those in eastern Australia have been all too familiar with over the last two soaking La Niña summers. 

According to Dr Margaret Cook, environmental historian and lecturer at the University of the Sunshine Coast and researcher at Griffith University. “The problem with a triple La Niña is that the ground is very wet already, our rivers are quite high, our creeks are full and our dams are quite full,””So we have less capacity to absorb this enormous amount of rain.”

It does not necessarily follow that this summer will definitely bring biblical floods.

But it doesn’t rule out the possibility of floods this summer. 

During a La Niña, the atmospheric circulation across the tropical Pacific is set up so that warm waters to Australia’s north-east and strong trade winds pump moisture into the atmosphere along Australia’s east coast. When the right systems come along they can then tap into that moisture, bringing about heavy rains and flooding. 

A situation all too familiar for those situated on the east coast of Australia.

Like many Australians, we wanted to find a useful way to help those that were affected by the floods.  

Lismore resident Christine Porter created a fantastic initiative to distribute Emergency radios to the flood stricken Lismore and surrounding community.

 Aptly named EMERGENCY RADIO Project Lismore Floods 2022.

Nsw floods

Christine found the BEST Emergency Radio by Tecsun Radios, Sydney. She realised that, as well as it being a great AM/FM radio, its primary function for emergencies matched the emergency we’d just had. It’s a torch, lightweight, stable, not too small. Its lithium battery is charged by USB, an inbuilt solar panel, or its own crank handle. It can be used as a power-bank, will pick-up shortwave, but most importantly: it has a siren and flashing beacon. 

After long discussions with the principal at Tecsun, and testing one herself, she believes something like this would have made a very real difference the night of the flood. Next time there may not be a bloke in a tinny going past at just the right time. 

Her aim is to put one of these radios into as many single-person households returning to the flood zone as she can – especially for older or less-abled people. The river rose 2.4 metres (8 feet) higher than the highest flood on record, so the flood zone has spread into parts of suburban Lismore it never had before. Christine has ordered 50 radios, with an option for another 50 later in the year. Her plan is to contact groups or individuals outside the North Coast region to fundraise for the purchase of the radios, in order to spread the volunteer load, and give people a specific way to help. Tecsun has kindly offered a discount  to support Christine.

Lismore is still broken; there is so much still to do. If you, or your organisation would like to contribute, Christine has set up a bank account to receive donations for the radios. She’ll send you a receipt and follow up info about how the project is going. If you’d like to send a card, or message to the recipient of your radio/s she’ll pass that on. It’s the small things as well as the grand gestures that we see making a difference. That night, in the rain and the noise, no-one would have imagined we’d all be still here knee-deep (waist, chest and chin deep) in worry so far into the future. Christine believes that the radio will save lives should an event like this happen again, but it will also reassure the traumatised that this time, if need be, someone will be able to hear them call out in the night.

RNZ shirtwave

In recent and welcome news, RNZ (Radio New Zealand) shortwave radio broadcasts have resumed from the hours of 5am to 9am ( NZ time) to the ​​Pacific region. A service that ceased back in 2016.

As a result of this decision, listeners in the remote areas of the Pacific will now have 24-hour access to these broadcasts instead of it turning off early in the morning every day. 

We have previously reported just how important these broadcasts are for many remote communities who regularly endure unexpected weather patterns and can lose contact with the mainland and emergency services. Emergencies don’t stop between the hours of 5am and 9am, therefore access to emergency broadcasts shouldn’t either.

We applaud the decision by the NZ Government to contribute extra funding for shortwave services. We hope the Australian Government is taking notes!

One of the most widely listened to broadcasts is the RNZ Pacific’s flagship daily current affairs programme Pacific Waves which is also broadcast by the BBC Pacific Service.

So, what will be broadcast ? At various times RNZ will run 3 different frequencies, at 5am NZT tune in on 7425 kilohertz, at 6am NZT listen on 9700 kilohertz, and at 8am NZT change the dial to 11725 kilohertz

For the full schedule of shortwave frequencies check out the RNZ Pacific website.

lighthouse radio competition

Have you heard of the International Lighthouse weekend? This is an annual event held by International Lighthouse and Lightship Weekend (ILLW) where radio operators connect with each other from all around the globe on this one weekend in August. But the difference, they are all operating from different lighthouses around the world!!

 

This year it falls on August 20-21. This will be the 25th anniversary of the event. Because it is not a contest, amateurs may operate on any authorised frequency and mode permitted by their licence. 

We came across an interesting article containing suggestions of the origins of this event.

This idea originated after a cold winter in 1992-1993  after two avid amateur operators wanted to encourage operators to get out in the summer and “play radio” . Originally some ideas like historic Scottish castles, however, they decided that the lighthouses of Scotland would be ideal!! The event was not to be a contest but simply “fun” time for the whole family. Take your family to the beach for a picnic and use your radio as an added bonus that day/ weekend. 

It would appear that two lighthouse events were held for many years until eventually, the ‘The Amateur Radio Lighthouse Society assumed sponsorship and management of the ILLW event.

Want to listen in on the event? Most operation will take place on the HF bands, so this is an opportunity to listen on your Tecsun shortwave receiver. Normal operating conventions apply, so frequencies below 10MHz utilise LSB and frequencies above 10MHz use USB (upper sideband).

The Tecsun PL-365, Pl-368, PL-880, PL-990x, and H-501x can all be used for this event and we recommend our Outdoors MW/SW antenna also!!

Please note, this is by no means the complete list but will give listeners an idea if the lighthouse closest to them will be operational. 

 

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.

drm radio australia

 

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.

antenna shortwave drm

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 !
