Have you heard about the fox hunt? 

Radio direction finding (Fox Hunting) is used to find sources of interference to any form of wireless electronic communications, including broadcast and two-way radio. Amateurs use RDF for a variety of reasons, but more often, they use it just for fun. Hidden transmitter hunting has been done by amateurs for many years. Using ‘hide-and-seek” procedures, amateur radio operators (“Hounds”) take up the task of finding hidden transmitters (the “Fox”). Numerous cunning tricks are played by those hiding a Fox as they seek to elude the Hounds. In Australia, Foxhunting includes travel in a car, and DFing a hidden transmitter on the move, whilst following all current road rules. Then the Hounds, become pedestrians to discover the hiding spot of the transmitter, the “Fox”. Foxhunts can also be held over relatively short courses requiring Hounds to do all of their DFing on foot. Sometimes the”Fox” may be disguised to make the hunt more difficult, so watch out for “Wolves” when you are hunting too. Whatever the case, it is a fun activity!

Fox Hunt Purpose:

  1. a) Provide practice and enhance skill in radio direction finding for and by radio amateurs.
  2. b) Promote teamwork within the amateur community.
  3. c) To help newcomers and old-timers alike in the skills of radio direction finding.

But most of all:

  1. d) To have fun!

anzac day military radio history

As ANZAC day approaches this year, it’s a good time to reflect on how radio communications has evolved over time, accelerated by wartime conflicts, and how difficult it must have been during times of conflict.

Prior to the introduction of radio communications, messages during wars were sent using dogs and homing pigeons. Short range communications utilised signalling lamps and mirrors with limited success

Towards the end of World War 1, the introduction of “spark” or “loop” radio sets, operating on the longwave band, and utilising CW (morse code) was recognised as a great step forward in technology. These sets were used between different groups on the battlefield, as great improvement over messengers who were continually under fire from snipers.

In September 1914, one month after the declaration of war, at the battle of Bita Paka, Australian forces attacked the German South Seas Wireless Station on the island of New Britain, conquering German New Guinea.

By the end of World War 1, despite the equipment being heavy and bulky, CW communications had been used by Australian military forces on land, sea and air.

Considered to be more advantageous to naval and airborne forces, where existing telegraph lines could not be employed, this technology paved the way for more advanced voice communications employed after 1920.

Between wars development of radio communications equipment continued, as the benefits of instant communications to direct armed forces was realised.

By 1939 local industry was gearing up to manufacture radio receivers for expected consumer demand of the new technology which provided news and entertainment from around the world.

Governments around the world soon realised that radio was a very effective propaganda tool. Nazi Germany and the British government used it to muster support from their respective populations. In fact the German military arranged the manufacture of millions of radio receivers which were subsidised, allowing access to the general population.

In America, the Office of Co-ordination began providing programming to commercial shortwave stations, in order to spread the news of the war in Europe and the Allied response.

At the end of August 1939 in Australia, all shortwave transmissions professional and amateur, were ordered shut down.

A few weeks after the declaration of war in September 1939, Mr (later Sir) Robert Menzies, the Prime Minister, inaugurated a government controlled overseas shortwave service to counter German propaganda in the Pacific. Initially called “Australia Calling” and using the callsign VLQ2, the service commenced on his birthday, December 20 1939. This service later became Radio Australia.

Whilst telephone and telegraph cables carried some traffic in war zones (a cable was laid under the English Channel between France and England), radio communications became a necessity during World War 2 and the simultaneous development of radar technology accelerated the development of “portable” radio transceivers, so large and heavy that they had to be transported by cart or jeep. In Australia, manufacturers like AWA, STC, Astor (Radio Corporation of Australia) and Kingsley began manufacturing radio equipment for land sea and air forces. Coastwatchers in northern Australia, Solomon Islands and New Guinea used AWA’s 3BZ receiver and 3BZ Teleradio transmitter to intercept Japanese communications and relay important information to the Australian and US navies patrolling the pacific.

3BZ Teleradio system

Typical of the bulky equipment of the time was the Number 11 set was manufactured by AWA. It was a combination transmitter receiver, operating on the HF bands, and drawing 2.9 amps on receive and 3.3 amps on low power transmit (1 watt), a far cry from today’s modern transceivers. It weighed 20Kg.

No. 11 Transceiver Anzac             Subsequent to the World Wars and both before and during the Korean and Vietnam Wars, communications equipment was developed and refined to suit modern warfare techniques.

By the early 1950’s military communications equipment had progressed significantly. AWA were making the A-510 transceiver which was a portable, battery operated, 4 channel crystal controlled transceiver covering 2-10Mhz. Despite the low RF power output of 150mW when using voice communications, the established range was over two miles in the portable configuration and over 100 miles when used with a half wave dipole in “ground station” mode. It weighed 9Kg

anzac radioBy the beginning of the Vietnam War, most military radio communications equipment was manufactured in the USA. Troops in Vietnam used the AN/PRC 25, a valve, multichannel VHF FM transceiver with a power output of 2 watts and a range of approximately 5 miles. It weighed 12Kg. This model was superseded by the PRC-77 which was also VHF FM, had the ability to use voice encryption, and had a solidstate power amplifier, reducing the weight to 6kg.

PRC-77 Transceiver

By the 1970’s AWA was producing a fully solid state HF transceiver covering 2-12Mhz in 1Khz steps, utilising CW and USB modes, operating from an internal Nicad battery, and was capable of 10 watts PEP output power. The receiver drew 35mA, and the entire transceiver including backpack weighed just 9 Kg

This snippet of radio equipment development history allows us to contemplate the huge improvement in performance, and at the same time give thought to those who persevered with heavy cumbersome and poorly performing equipment, during times of conflict.

Lest We Forget.

world amateur radio day

World Amateur Radio Day

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

Date: April 18, 2021

Time : All Day

This year’s theme is “Amateur Radio: Home but Never Alone.”

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.

A humbling reminder that we are a global community that has united during a time of isolation to ensure we remain connected and available to assist those in need.

Radio is a fantastic way to discover radio programs from different regions both music and news from unfiltered sources, in addition, a fantastic way to receive crucial weather, aviation and safety broadcasts whilst out of many standard network zones.

Take some time on Amateur Radio Day to explore the world of Amateur Radio and discover what new friends and communities exist all over the world.

A fantastic radio to use on World amateur radio day is the Xiegu G90 transceiver.

To celebrate World Amateur Radio Day, with every G90 purchase we will include a free CE-19 expansion interface worth $80. Use the Expansion interface to connect your G-90 transceiver to a PC, data terminal or modem for operation in digital modes.

As the weather begins to cool, it is a great time to set up and organise your radio shack.
Crucial for wireless communication, the first radio shacks were aboard ships in the 1900s, several radio units were housed above the bridge in wooden structures.
Similar to a man cave the radio shack is essential for every shortwave listener, it is your place to get away from the hustle and bustle.

image via qsl.net

Many radio shacks are set up in basements, garages, or spare rooms.
Some important factors to consider are.

Location: Ensure your radio shack is as close to the ground as possible with accessibility for routing wires in and out of your space.
Comfort: Get yourself a large desk that can accommodate lots of radios and a comfortable chair so that the time you spend in your shack is enjoyable. Get yourself a good set of headphones that can plug right into your radio, preferably like our Tecsun communication headphones that feature an extra-long cord so it can reach even the higher up radios in your radio shack.
Ease of use. We mentioned the large desk earlier, it is important to have your units within close reach, at least within arm’s length. Buying some shelving for vertical storage is both a great use of space and helps accessibility.
The Extras, just for fun! Get yourself a big clock that shows Zulu or UTC time so you can always see what time it is overseas, plus these look pretty cool!
Get yourself a corkboard that you can pin your QSL cards, decoded images, and other notes.

For those of you who have a radio shack we would love to see your photos. Take a photo and either email it through to hello@tecsunradios.com.au or post your photo and tag us @TecsunAU and #TecsunAU.

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.

 For full information about the contest, contest history, rules and definitions please head to the Wireless Institute of Australia website.

 

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.
