Australian code breakers in World War II

Many thanks to SWLing Post contributor, Ian P, for sharing the following from the radio program, ABC Overnights:

The crucial role of Australian code breakers in World War 2

Thanks to the recent film, The Imitation Game, you may be familiar with the story of how British intelligence, led by mathematician Alan Turing, cracked Nazi codes during WW2. Did you know there were also two secret organisations in Australia working to break Japan’s military codes?

These were staffed with brilliant cryptographers, including some who had studied mathematics and the classics, and others who had lived or grown up in Japan. By patiently and carefully unravelling the codes in Japanese signals, their intelligence played a crucial role in the battles of Midway and the Coral Sea, as well as the push into the Philippines.

4KZ: More info about Australia’s new shortwave broadcaster

Many thanks to Al Kirton, the General Manager at NQ Radio, who has kindly shared a few more details about NQ Radio and, specifically, 4KZ:

Hello Thomas

NQ Radio operates about 20 AM & FM transmitters in North Queensland, Australia. Our stations are 4KZ, 4AM, 4AY, KIK FM & KOOL FM.

In a couple of months or so we will be establishing a 4KZ shortwave service on 5055 kHz with 1 kilowatt.

The antenna is designed to give primary coverage from 200 km to 800 km from Innisfail. We suspect it will be heard with a low quality signal much further away.

Sincerely

Al Kirton
General Manager

Many thanks, Al! We’ll be listening!

RadioWorld: Despite Fears, ABC Shuts Down Shortwave Broadcasts

(Source: RadioWorld)

The ABC has turned off its shortwave radio transmitters, leaving Australians in remote areas without easy access to lifeline radio

OTTAWA — On Jan. 31, state-owned Australian Broadcasting Corp. shut down its shortwave radio transmitters; ending both international broadcasts of Radio Australia and the ABC’s domestic service in Australia’s Northern Territory. The transmitters were located at ABC broadcasting facilities at Katherine, Tennant Creek, and Roe Creek (Alice Springs).

According to the ABC news release that announced the shutdown on Dec. 6 — less than two months before it took place — “The move is in line with the national broadcaster’s commitment to dispense with outdated technology and to expand its digital content offerings including DAB+ digital radio, online and mobile services, together with FM services for international audiences.”

[…]The majority of ABC audiences in the Northern Territory currently access ABC services via AM and FM and all ABC radio and digital radio services are available on the Viewer Access Satellite Television (VAST) satellite service.”[…]

Radio Maubere: clandestine radio in occupied East Timor

Radio-Dial-Blurred-Dark

Many thanks to SWLing Post contributor, Phil Brennan, who writes:

Your readers may be interested in this article detailing a clandestine radio station that was set up between the Fretlin rebels in East Timor (now Timor Leste) and supporters based in Darwin where I live. The Fretlin rebels fought against the Indonesian occupation until the country’s independence in 2002. In the 1970s this was the only method of obtaining information on the brutal repression of the Timorese people by the Indonesian dictatorship

The man featured in the article, Brian Manning Snr., who died a couple years ago was a well known activist and trade unionist in the Northern Territory. He was also very involved in the campaign for Aboriginal workers to receive equal pay and conditions in the 1960s. This campaign was instrumental in raising the profile of the Aboriginal land rights movement in Australia. Brian Manning Jr. Is a good friend of mine.

If someone was to make an Australian version of Forrest Gump, they might look to Brian Manning’s life story for inspiration.

In 1966, he helped the Gurindji strikers in the Wave Hill walk-off. When Cyclone Tracy hit his hometown of Darwin, police commandeered his truck to collect dead bodies. Months later, he became involved in possibly the most important mission of his life.

That mission was Radio Maubere: an underground radio link that operated between Darwin and occupied East Timor during the 70s and 80s.

For many years, it was the only link the Timorese had with the outside world.

“Dad felt very strongly that these people needed to be supported in their struggle,” his son, Brian Manning Jr, said.

“So with a few other people, they got together and formed this radio operation.

“It was vital. There’s no doubt that the Indonesians were in there to systematically reduce the population by any means necessary.

“So these people were just killing people, and these stories had to get out.”

[…]As the years went on, and the list of confiscated radio transmitters grew longer and Manning’s tricks became more and more creative.

“They had a few decoy vehicles. And they had a few decoy radios. And they had people rendezvous with them in the bush in certain areas,” Brian Manning Jr said.

Often one person would set up the transmitter, another would come along and use it, and a third would arrive to pack it up and transport it out of danger.

[…]The broadcasters even devised their own coded language to communicate top secret information, remembers one of the group’s members, Robert Wesley-Smith.

“They each had a book, and the code would direct them to a page or something. It was very slow … but it was a great adventure,” Mr Wesley-Smith said.

Whatever problems Manning and his crew had in Australia were nothing compared to the dangers faced by those operating on the other end, where gunshots could sometimes be heard in the background.

There was a constant need to get new transmitters into the country, and an engineer from Sydney came up with an ingenious method for avoiding detection.

“It now fell to the resourcefulness of Andrew, who created a transmitter out of a ghetto blaster,” Manning wrote in his book.[…]

Mark’s multi-user SDR is now online

mark-fahey-beagle-kiwi-sdr

SWLing Post contributor, Mark Fahey, has just announced that his new Beaglebone-powered KiwiSDR receiver is online.  Mark notes:

Please try out my multi-user 0-30MHz SDR[.] The test system is operating from my monitoring station at Freemans Reach in south east Australia (near Sydney).

Freemans Reach, Australia

[…]The test system is fully self contained and self operating. The antenna (ALA1530S+) we are using is a magnetic loop with an impedance tracking amplifier designed and manufactured by Wellbrook Communications, Llanwrth Wells in Wales. The receiver and CPU is the result of the Kickstarter funded project “KiwiSDR” which was conceived and designed by John Seamons ex Pixar and Lucas Films.

[…]You can use Chrome, Microsoft Edge, Safari, Firefox – but Internet Explorer is not supported at this stage. Tune in on this URL…

Many thanks for sharing your KiwiSDR, Mark! Though demand has been quite high, I have managed to claim one of the four user seats on Mark’s SDR and “listen like a local.”

Mark: you’ve done a great job making a proper listening post for your remote listeners. The KiwiSDR/Wellbrook ALA1530S+ combo is performing admirably!

Update on Radio Australia outage

Australia

Many thanks to SWLing Post contributor, Dan Hawkins, who left the following comment in reply to our previous post about Radio Australia’s outage:

This message found on the ABC/Radio Australia website this morning…

The ABC is running a technical outage of the international shortwave service until Friday the 19th of August to test reception in the region.

Listening to shortwave requires a specialist shortwave radio. We direct our broadcasts at peak listening times in our target areas of the Pacific using multiple frequencies. We recommend that where possible, you use an outside antenna to improve reception. Shortwave signals may be subject to interference from other broadcasters’ signals, electronic devices such as computers, microwave ovens, TVs, car engines and fluorescent lights.

Thanks for passing this along, Dan. This is the longest technical outage I’ve ever noted from Radio Australia.
