The John Moyle Field Day will be held over the weekend of the 20th-21st March 2021 and will be run from UTC 0100 on Saturday to 0059 on Sunday.

The aim is to encourage and provide familiarisation with portable and field operation, and provide training for emergency situations. The rules are therefore specifically designed and focussed to encourage field operations.

The John Moyle Field  Day Radio contest is held in honour of the late John Moyle, a long term editor at the Wireless Weekly, Australia’s first news-stand wireless magazine (not counting the AWA monthly), published in 1922 which later became, Radio & Hobbies – later Radio Television & Hobbies) magazine from 1947- 1960.

During his service in the RAAF during WWII, he was responsible for keeping radio and radar equipment working using innovative solutions during very difficult war time conditions.

The WIA decided to dedicate a long term memorial to John Moyle in the form of an annual Field Day with a focus on portable or field operation. 

Over the years the contest has evolved to not only include portable or field operators but also include home stations who may also take part using a different scoring system.

A fantastic radio to use for the HF part of the contest is the Xiegu G90. This unit is portable and can be run off your car battery.

The HF amateur radio dipole Antenna covers the popular 5/7/10/14/18/21/24/28 and 50Mhz bands. The antenna is rated at 100Watts PEP power handling capability and is supplied in a convenient canvas carry bag.

The antenna comprises a 1:1 balun and 2 bobbins containing the appropriate amount of wire to cover the specified bands.

Contestants can enter for either 6 hours or 24 hours.

The Xiegu G90 is the ideal transceiver for the Hf part of this contest. For those who are not amateurs this is the ideal weekend to listen to amateur radio in action and to evaluate antennas etc.

The aim of the contest is to score the most points, by making as many contacts as possible.

On the HF bands, 2 points are earned per contact. Other points scales apply to VHF/UHF, dependant on the distance over which the contact is achieved.

The contest is open to all VK, ZL and P2 stations. All other stations are welcome to participate, but can only claim points for contacts with VK, ZL, and P2 stations. All VK, ZL, and P2 stations can claim points for all contacts, with any station in the world, as long as valid serial numbers are exchanged.

The contest rules ensure more logs are submitted, by requiring that if any station works the same station a total of more than 10 times on any band or on any mode then the logs from both stations should be submitted to verify those contacts.

Single operator portable entries shall consist of ONE choice from each of the following (e.g. 6 hour, phone, VHF/UHF):

a 24 or 6 hour;

b Phone, CW, Digital or All modes;

c HF, VHF/UHF or All Bands.

Multi-operator portable entries shall consist of ONE choice from each of the following (e.g. 24 hour, phone, VHF/UHF):

a 24 or 6 hour;

b Phone, CW, Digital, or All modes;

c HF, VHF/UHF or All Bands.

Home entries shall consist of ONE choice from each of the following (e.g. 24 hour, phone, VHF/UHF):

a 24 or 6 hour;

b Phone, All modes;

c HF, VHF/UHF or All Bands.

Multi operator stations are not permitted in the Home Category.

 

If any Station works the same station more than 10 times in total using any band and, or using any mode, they should submit their own log to verify those contacts for the other station.

Saturday is World Radio Day Feb 13 2021!

Since November 2011 the world has been celebrating World radio day. The day was proposed by Spain and unanimously accepted by UNESCO

Radio was invented over 120 years ago and is one of the most important inventions of the modern world that Helps us stay in touch.

Radio had been recognized as having such a profound impact on the modern world, that the United Nations established as ‘World Radio Day’ to be celebrated on February 13 every year. On September 29 2011 the UNESCO officially proclaimed that it be established the following February and so the first World Radio Day was celebrated on February 13, 2012. UNESCO describes the radio as “a powerful medium for celebrating humanity in all its diversity and constituting a platform for democratic discourse.”

Radio has been with us longer than any other kind of broadcast media with the result that more people have access to radio than anything else. There are several benefits of radio over other media. Radio is free, there is no cost to the listener. Radio covers huge areas and is not restricted by borders or government regulations.

“The cool thing about radio is it’s still relevant and important in our daily lives. During those long drives for vacation or maybe to work, radio is still with us, keeping us singing and keeping us informed. It’s like a great friend and neighbor, one who’s always there and never lets you down—except radio will never borrow your weed whacker and forget to return it.” – Nationalday.com

World Radio Day is a good opportunity to use your Tecsun shortwave receiver to listen around the world and appreciate the market served by this powerful medium.

Many technically inclined people have discovered shortwave listening in their youth. Years later they continue to the fascinated by what can be heard on the shortwave bands.

This is my story….

As a teenager, I became interested in radio by reading the hobbyist magazines of the day. There were tantalising ads for army disposals stores in Sydney full of communications equipment but beyond my modest means.  In my case, I acquired several old valve radios thrown out at the local tip. Much to the disgust of my parents, I regularly carried such prizes home and commenced my new hobby of listening to the radio bands.

In those days most home entertainment units were made of wood and contained a radio receiver that covered the broadcast and shortwave bands.  I was lucky to find one that worked. Quickly discarding the bulky wooden cabinet, the receiver became a benchtop unit, exposed in all its glory. The speaker used an electromagnet (no permanent magnets in those days) and the signal strength meter was a green valve indicator poking through the front panel called a “magic eye”.

The next step was to install an antenna which comprised the longest piece of wire I could find. I recall that unraveling the enamel copper wire from a transformer became the most cost-effective solution.

Soon I was listening to overseas stations, many broadcasting in English, and occasionally I heard important events. I recall clearly listening to the Victoria Police on one of their HF frequencies when they announced the search for a prominent politician who had gone missing in December 1967.

I informed my parents of this important event and they were amazed to discover a few days later that I had been listening to the search for the then Australian Prime Minister, Harold Holt who disappeared in the surf at Portsea in Victoria.

I enjoyed listening to distant MW stations all over Australia, and collected quite a few QSL cards from broadcasters around the world.

Believe it or not, a Broadcast Listeners Licence was required in Australia until in 1974, at a cost of $26.50, so there was a degree of secrecy involved in all this listening activity.

Eventually, my shortwave listening led me to an interest in Amateur Radio. I knew a local lad who was fortunate enough to purchase the entire correspondence course for the amateur exam and who loaned it to me after he obtained his license.

So in August 1973, I obtained my amateur radio license. Somehow I managed to make the required 90% pass mark, much to my amazement.

My first amateur radio transceiver was a converted Pye reporter VHF AM taxi radio. I recall it had a huge valve in the output stage, requiring several hundred volts from the power supply to operate. The only semiconductors were in the 12 volt inverter powering the entire contraption. When the push to talk button on the microphone was pushed, it took a few seconds for the voltage to build up sufficiently to allow the transmitter to operate!

From that point, there seemed to be an endless succession of different two way radios being fiddled with to obtain the best on air performance. During subsequent years I became interested in amateur television and satellite communications.

I recall in about 1975 being able to eavesdrop on the US operators of the Applications Technology Satellite 1 (ATS-1), the world’s first weather satellite. At the time my interest was driven by the fact that antennas for the VHF and UHF bands where physically manageable and easy to make.

However, my interest in VHF and UHF waned as mobile phones replaced the two way radio as the preferred method of communication and I became re-energised with shortwave.

In much the same way as my earlier experience with VHF and UHF was driven by the availability of ex-commercial equipment, so was my entry into HF communications.

Second hand commercial transceivers designed for use by the Royal Flying Doctor Service became available and soon I was running 100 watts on the HF amateur bands, communicating with people around the world.

Someone once told me that shortwave listening is like fishing… you never know what you are going to get. That certainly described my experiences.

One incident worthy of mention was receiving the USAF Strategic Bomber Command broadcasts. These coded transmissions were part of the US military control of nuclear weapons and could control the launch of ground-based missiles should war be declared! These broadcasts weren’t public knowledge at the time.

I also heard the US military MIA recovery missions into Laos and Cambodia at the end of the Vietnam war, fascinating listening. Over the years I have heard several successful search and rescue missions involving aircraft being ferried from the USA to Australia. On one occasion I heard a commercial cargo jet traveling from Australia to the US, circling a downed pilot until the US Coastguard could reach him.

To be able to listen to these situations unfolding in real time is one of the aspects of shortwave listening that makes it an exciting hobby, contrary to common belief.

These days I mostly listen on HF. There is an amazing range of broadcasts available to shortwave listeners, ranging from utility stations like the Bureau of Meteorology, 4WD networks, HF aircraft networks and VOLMET, and secret numbers stations, as well as regular, scheduled shortwave broadcasts from all over the world.

Now, listening is even easier, as broadcasting schedules are freely available, and the worldwide network of internet accessible KiwiSDRs provide a fantastic resource for shortwave listeners.

Receivers are now more affordable than ever and the hobby is enjoying a huge resurgence, in part due to the worldwide pandemic of 2020.

There is no time like the present to immerse yourself in the world of shortwave listening!

Shortwave radio listening is a hobby that allows you to fully immerse yourself in a separate world of international events. From listening to a shortwave broadcast station, long-distance aircraft travelling around the world or even international amateur radio operators, this hobby allows you instant access, to the exclusion of those physically around you.

To further enhance the listening experience, a good set of comfortable headphones is essential. Communications headphones, as distinct from those used for Hi Fi listening, need to be comfortable to wear for hours on end. At the same time, they need to be able to reproduce the full audio spectrum produced by the receiver, ensuring that even weak signals can be resolved adequately. Wired, over the ear headphones also have the advantage that there are no batteries to replace, contrary to Bluetooth and noise-cancelling headphones.

Another important requirement for a good pair of communications headphones is a long connection cable. Most Shortwave Listeners and amateur radio operators have their equipment set up on a bench or desk, which is often multifunctional. With adequate cable length (at least 2 metres), there is room to move around the “shack”, doing other things whilst maintaining a connection with the receiving source.

If you are going to invest in a good quality pair of headphones, it is important to be able to keep them in a safe place where they won’t get damaged and will be kept clean. A carry case is ideal for this, and this can also be used to keep any necessary audio adaptors (3.5-6.3mm adaptor to cater for all receiver types, for instance), and spare ear muffs with your headphones.

Here at Tecsun Radios Australia, we have held off selling headphones until we tested several on the market first to find the most suitable high quality headphones for shortwave listening.

Launching on Friday January 29 2021 we are proud to showcase the exceptional Tecsun Radios Australia communications headphones that have been specially selected with user comfort in mind. This is essential for long periods of shortwave listening.

Q codes were developed by Morse Code operators as a method of communicating quickly and accurately. Rather than send a complete phrase, Q codes were developed to cover most operational situations. Q codes can be used to ask or answer a question, and can be used by operators who speak different languages.

Q codes are approved by the International Telecommunications Union (ITU) for use on worldwide radio networks.

For instance if an operator wants to change to another frequency, he can simply advise the party he is speaking with “QSY 7050” meaning “I will change my operating frequency to 7050Khz”. Similarly he could ask “should I change to 7050Khz” by simply saying “QSY 7050”.

 

So the next time you hear an operator using a Q code, spare a thought for those old-time morse code operators and the time saved by using Q codes.

In 1843 the phenonema known as the Solar cycle was discovered by Samuel Schwabe a German astronomer who observed transitions of the Sun from periods of high activity to low activity every 11 years, over a period of nearly 20 years.

Put in simple terms, the Sun is composed of a huge ball of electrically charged hot gas. As this gas moves, it generates a powerful magnetic field. This magnetic field transitions through an 11 year cycle (known as the Solar Cycle) during which the magnetic poles of the Sun are transposed, ie the north and south poles change places.

This cycle affects activity on the surface of the Sun, such as sunspots and solar flares. The energy released by these events charges particles in the ionosphere, affecting radio propagation. More solar flares and sunspots occur at the peak of the cycle than at the bottom of the cycle. Typical values are 80-100 sunspots at the cycle peak and 15 or so at the cycle minimum.

When a strong flare occurs, the increased x-ray and extreme ultraviolet radiation produces ionisation in the lower, D (absorption) layer of the ionosphere, disrupting HF radio broadcasts by absorbing rather than reflecting signals. 

We are currently at the end of Solar Cycle 24 (calculated as mid 2020), and from this point we can expect an increase in solar activity and changed radio propagation as the maximum useable frequency (MUF) for shortwave communications increases with an increase in solar activity.

At the peak of the Solar Cycle, the higher frequencies of the shortwave spectrum are very good. Low power stations can be heard over remarkably long distances. 

At the bottom of the cycle, the current position, those higher frequency signals will not usually support normal propagation via the ionosphere. So propagation at lower frequencies will be better whilst higher frequencies will suffer.

shortwave radio saves airplane.

 

Imagine flying off the coast over a vast ocean when your communications are lost.

Regular weather condition reports, particularly regarding strong headwinds are vital to the successful flight and landing of  an airplane.

 

On July 9, an air ambulance departing Santiago De Chile to collect a patient on Easter Island lost satellite communications more than 1600Km from land.

Out of VHF range and with an inoperative satellite link, the fast thinking pilot tuned the aircraft HF radio to 7100Khz, the net frequency of the Peruvian Refief Chain who had just finished conducting a training exercise.

Fortunately for the pilot, 2 amateur radio operators Guillermo Guerra OA4DTU and Giancario Passalacqua OA4DSN, were still on frequency and able to respond to the aircraft. Together they communicated via HF with the aircraft and by telephone with the Ocean Air Control who have control of aircraft movements in the 32 million square kilometre Pacific Ocean Area off the coast of Chile.

shortwave radio helps distressed airplane

Meanwhile other amateur radio operators rejoined the frequency ready to provide assistance if necessary.

OAC were already in a state of alert since losing communications with the aircraft and as the backup HF communications system at Easter Island was out of service.

After 10 or so phone calls between the amateurs and OAC, providing aircraft position reports and advising weather conditions over a period of 3 hours, VHF communications was established with the control tower on Easter Island, and the aircraft made a successful approach and landing.

Radio frequencies for shortwave

Do you enjoy listening to shortwave and have noticed the frequencies used by your favourite broadcaster change twice a year? Interestingly there is a scientific reason behind this.

Shortwave travels long distances because of its unique way of propagating. The transmission is beamed upwards towards the sky where it is reflected back down to earth spanning a huge distance between the two points. In good conditions a single transmitter is able to reach millions of listeners around the world.

This is what makes shortwave unique and incredibly effective, especially to remote audiences as well as to areas where news and information is highly controlled. 

As a general rule, higher frequencies (SW) work best during daylight hours and summer time while lower frequencies (MW) work better in darkness – before dawn and during the long winter evenings. 

 This same frequency can not be used all year round because as the seasons change the number of daylight hours at any location can directly affect the optimum frequency band. This is because the energy from the Sun required to ionise reflective layers in the upper atmosphere is directly impacted by the sunlight hours available. So seasonal changes causing shorter sunlight hours will affect daily propagation of a higher frequency, and so a lower frequency will need to be chosen to provide similar coverage during the period of shorter days.

The High Frequency Coordination Committee (HFCC, under the ITU International Telecommunications Union) is the body that has the responsibility to decide when to change shortwave  frequencies.They must coordinate these changes with all the major shortwave broadcasters around the World.

To ensure the optimal transmission conditions the HFCC recommend  two seasonal frequency schedules – summer and winter – known as the ‘A’ and ‘B’ seasons.

The changeover between seasons is internationally agreed to occur on the last Sunday in March (start of ‘A’ season) and the last Sunday in October (start of ‘B’ season), which coincides with start and end of ‘Daylight Saving’ in many countries, where local time can change.

The changeover ‘A20’ season has just occurred on Sunday 29th March, and the frequencies agreed for all shortwave transmissions will continue until the beginning of the next season ‘B20’, on Sunday 25th October.
