Beijing jamming Radio Australia

The media has finally noticed that China is jamming English broadcasts:

A growing electronic blitzkrieg by Beijing - blasted by Barack Obama as "state sponsored" hacking and now extending to the jamming of Australia's radio news broadcasts in Asia - threatens to derail delicate negotiations for the ABC to win television rights in China.

ABC managing director Mark Scott and chairman James Spigelman are expected in China next month to launch a major children's program co-production with Chinese state television. The trip is also another chance to lobby Chinese officials in long-frustrated efforts for the ABC to win access rights for television broadcasts in the 1.3 billion-strong market.

But the goal has been further complicated after China was accused of deliberately jamming Radio Australia broadcasts in Asia over recent weeks, a move that will also compound fears about Beijing's aggressive attempts to hack Western computer networks.

Mr Obama on Wednesday accused hackers of stealing billions of dollars in industrial secrets and singled out China for the toughest criticism to date over the issue.

"We've made it very clear to China and some other state actors that we expect them to follow international norms and abide by international rules. And we'll have some pretty tough talk with them. We already have," he said.

The jamming of Radio Australia - extending to the BBC World Service and the US Voice of America - is said to be the first time China has set out to disrupt English-language services in the region. The service has been blocked on several frequencies broadcast from short-wave antennas in Singapore in what is seen as an overall crackdown by China to prevent access to foreign news.

The BBC has condemned the interference, saying it was ''designed to disrupt audiences' free access to news and information''. The claims follow evidence Chinese hackers penetrated New York Times computer systems over several months.

The BBC admitted it was impossible to pinpoint the source of the jamming but said the ''extensive and coordinated efforts are indicative of a well-resourced country such as China".

The ABC has not itself drawn attention to the disruption but, asked on Thursday, a spokeswoman said the network strongly supported the free flow of information and objected to interference of any broadcasters' transmissions.

"While we have received reports of interference of our signal into China it is extremely difficult to identify or confirm the source of this interference and we will continue to monitor the situation as well as consult with partners in the region. No formal complaint has been lodged," she said.

The ABC also endorsed a statement made last week by the Association for International Broadcasting - a grouping of major global media organisations - claiming research by the broadcasters and independent monitors indicates the source of the jamming is within China. The organisation said it would lodge complaints with the Chinese Foreign Ministry.

China has long disrupted Mandarin-language services produced by foreign countries and refused overseas broadcasters what are known as landing rights for TV, including multiple bids by the ABC.

This is despite Chinese state media expanding their presence in Australian cities on radio and television with news broadcasts most analysts agree amount to little more than official propaganda.

La Trobe University political specialist James Leibold said Chinese authorities had always tried to control the flow of information into the country.

But he said extending the ban to English-language services probably reflected sensitivity during China's recent leadership transition.

Mr Scott and Mr Spigelman's trip to China is to launch a 52-part preschool program co-produced by the ABC and China's CCTV.

A spokeswoman for the Chinese embassy in Canberra did not respond to requests for comment.

Indonesian Horse Racing on 7000kHz and 11425kHz



This is one of those odd things that makes shortwave radio so intriguing. I first heard these strange chanting on 7000kHz LSB a few years back and have been running into them quite frequently. In December I found the same phenomenon outside of the Amateur bands on 11425kHz USB and recorded it, which I have presented a short excerpt for you.

Many people have theorised as to what these strange chanting are about - from number stations to some sort of call to prayer. I believe they’re from Indonesia and are using identifiers to chant over one another to see who is able to be heard above the rest. K9RZZ on the radioreference.com forums said amateurs used to call this “Horse Racing” and I’d have to agree with him. It sounds like they take turns being the MC, to judges who is the winner and to introduce the players to compete. The MC says start and the participants chant their Ids for twenty seconds or so. The winners from each round get to play off against each other until an ultimate winner is found, who gets to take home the prize hamper. This seems to go on for hours, the earliest I’ve hear them on air is about 1100z and the latest was 1700z (3am local) when I tuned out for bed (it may have kept going).


In this video you can hear the MC introducing the players and very enthusiastically starts their 20 second race by saying in English “GO! Go! GO! Go! GO!”

I’m located in Melbourne Australia and recorded it using a Soft66ADD SDR joined to a 10m vertical antenna.

If you have any other clues or ideas please post them in the comments.

Early Shortwave Memories David Smith


For most parts of the world, shortwave is no longer the medium of choice. There are exceptions, where it has become a medium of last resort. I have been asking people who confess to being SW listeners at early age to share their recollections. David Smith of Okapi Consulting in Johannesburg had this anecdote about listening to Radio Moscow in the 1970's.

Firedrake - the full 60 minute audio mix


From the SatDirectory site:

"A search with our 3 meter dish has found Firedrake! The audio is transmitted on Chinasat 6B within the China National Radio (CNR) satellite feed circuits. Many of the China National Radio feeds are in stereo, however one channel that is solely mono is CNR 8 - The Voice of the Minorities broadcast which features programs in the Kazakh, Korean, Mongolian, Tibetan and Uighur languages. The CNR 8 audio feed to the Chinese transmitter sites can be found on the left audio channel of a feed circuit labelled "Lzh8Rdjy". On the right audio channel of this feed is the audio for the Firedrake transmitters."

Fretilin's Clandestine Radio Transmitter


"One of the group’s activities was operating a clandestine radio network between East Timor and Darwin. It was the source of broadcast news getting out of East Timor from 1974 to 1976. Members of the radio group were racing along outback tracks, setting up their ex-wartime transmitters and receivers, making contact with East Timor, then hurriedly dismantling their gear, with the police, ASIO, the Army and Telecom officials hot on their tails. It was like a combination of Dad’s Army and the French Resistance being stalked by radio-detection vehicles of the German signals corps."

Australian National Maritime Museum has the transmitter in the photo.

Nerdcore Collapsible Fabric Yagi Antenna


"One of my favorite ham radio activities is making contacts on satellites. It's really fun to know that you're controlling something that's receiving and sending communications from space. But communicating with satellites means carrying a big Yagi antenna around. So, I decided to use my fashion sewing skills to make a collapsible fabric Yagi antenna that's much easier to transport."
