CHINA   Program content of the "Firedrake" network jammers changed last
weekend, is rather a CNR/CRI satellite feed channel re-shuffle, see mail
below by Mark Fahey.

Puzzle -- Firedrake on 15635 kHz at 1300-1400 UT, against UNID service ?
Maybe another Xi Wang Zhi Sheng SOH-Sound of Hope service from Taiwan?
(wb, wwdxc BC-DX TopNews Apr 19)

Firedrake, 1514-1535, April 16. Scanned every 5 kHz. from 7000 to 19000,
but did not find any noticeable Firedrake. Are they really gone?
(Ron Howard-CA-USA, dxld Apr 19)

China jamming service now changed the format, continous playing of dragon
music via the JAMMING NETWORK stopped now.

Few and between advertising talk [Howard and Hauser said China National
radio 1st program relay] and music jammer but rather lyric Chinese love
songs played now, even Elton John sung in between. Some 3 to 4 very fast
echos of few un-synchronized transmitters appeared as 'new sound'. Modern
Chinese and international smooth love songs in between.

Is full in action like in past weekend log, - frequ against txions in
Mandarin, Cantonese, Tibetan, Uighur, Nepali etc. noted here in Europe on
45 shortwave channels:

Jamming from China to PEAK soon!
This year marks the 20th Anniversary of the Tiananmen Square crackdown and
the authorities in China are getting ready. The State Administration of
Film, Radio and Television (SAFRT) has already sent out a memo to CCTV
(Central China Television), CNR (China National Radio) and CRI (China
Radio International) as well as the thousands of local provincial radio
stations to inform them about the "special measures" that will be in place
from May 18th to July 31, 2009.

Jamming during this period will also be stepped up. So if you tune to the
SW dial starting on or around that date, the very popular FIREDRAKE [not
at present, see above, wb] will be heard just about everywhere and
anywhere in the world. As many of you might know, Firedrake does not just
interfere with signals beamed to China, but also with signals beamed to
other regions.
(Keith Perron-TWN, dxld Apr 22)

"Programme" content of the "Firedrake jamming network" changed last
weekend, all acc to observations of Ron Howard-CA-USA in dxld.

Only FOUR REAL Firedrake dragon music jammers noted here in Europe,
remained on air since Apr 19:

15150* approx. 0400-0600
15635* 1300-1400
15820* approx. 0400-0600
15840* 1000-1200

Formerly also on 13970, and 15900 kHz against Xi Wang Zhi Sheng SOH-Sound
of Hope service from Taiwan.

Somebody in the Pazifik, Far East, or South Asia should monitor the
shortwave bands in the 0000-0500 UT portion.

"Firedrake" jamming service now changed the format, continous playing of
dragon music stopped now. Few and between advertising talk [Howard and
Hauser said China National radio 1st program relay] and music jammer but
rather lyric Chinese love songs played now, even Elton John sung in
between. Some 3 to 4 very fast echos of few transmitters appeared as 'new
sound'. Modern Chinese and international smooth love songs in between.

Is full in action like in past weekend log, - frequencies against txions
in Mandarin, Cantonese, Tibetan, Uighur, Nepali etc., noted here in Europe
on 48 shortwave channels, like on additional:

15265  0300-0600 IBB UDO, echo     15490  0300-0600 IBB IRA, echo
17615  0300-0700 IBB TIN, echo     17635  0300-0700 IBB Irkutsk-RUS echo

Who is Keith Perron, from Taiwan ?
Is a real character or an outlet of a western intelligence service?

Re: new echo sound recording.
Thanks for the audio. You heard a typical CNR-1 echo jamming (operating
more than one jamming transmitter and out of sync, causing echo). It is
non-Firedrake jamming, i.e., not non-stop Chinese music jamming. There
have been many of these echo jammers used on many frequencies for some
time now. The attachment is a recording from March 9, 2009, at 1308 of
another typical CNR-1 echo jamming, in this case supposedly against Ming
Hui Radio on 6030. Heard // 5030, a standard non-jamming CNR-1 station.
Thanks again for sharing this information!

Real Firedrake observations:
April 19 at 1312 on 9000, and at 1316 just barely audible on 8400. April
20 at 1227, good on both 9000 and 8400; at 1325 gone from 9000 but still
on 8400; ditto at 1346 and 1424 rechex. Firedrake, April 21 at 1325: on
8400 and weaker 9000 kHz.
(Glenn Hauser-OK-USA, dxld Apr 21)

Observed 0215-0245, April 23:
Firedrake (non-stop Chinese music jamming): 17300 and 18320, both // and
against SOH.

CNR-1 (assumed) distinctive echo jamming, all parallel: 11830 and 11925
(both against VOA), 17730 (against R. Free Asia) and 17765 (against VOA).

Assume the echo programming was CNR-1, due to the absence of a known non-
jamming CNR-1 to check these with during this time period.
(Ron Howard-CA-USA, dxld Apr 23)

I just now drove my dish across to Chinasat 6 to see if there had been
changes to the Firedrake transmitter feed. And I can report yes there has!

The circuit that carried Firedrake is right at the moment carrying what
sounds like a drama with some intervals of Mongolian Throat Singing, just
as I started typing they have gone to commercials and now at the top of
the hour the feed has gone silent. I will stick with this channel to night
and see if I can find some parallels on HF. It maybe that they have
reorganized some circuits, and what I am hearing is not feeding the
jammers - anyway within a day or so I should have it worked out.

[later] Our friends in Beijing seem to have done a major reorganization of
their satellite transmitter feed circuits on Chiniasat 6B. Where Firedrake
use to be it now seems to be a CRI feed, Firedrake now has it's own stereo
circuit labeled "ZY18 Stereo" - the program still seems to be in mono
though.

What is new is that now the CNR (China National Radio - Domestic) and CRI
(China Radio International) circuits are combined in same group of
channels. Previously I had to access one satellite for the CNR feeds
(Chinasat 6B) and another (Intelsat 8) for the CRI feeds.

At the moment on Chinasat 6B there are 50 separate stereo program
transmitter feed channels operating. CNR circuits are named "ZY xx" and
CRI are named "GJ xx".

Perhaps one or more of the more sleepy of the Firedrake jammer transmitter
sites are yet to catch up with the changes and at time "accidentally"
putting the old Firedrake circuit to air instead of the new Firedrake feed
of ZY18 Stereo.

Broadcast Jamming Continues in Post Cold-War World

Broadcast Jamming Continues in Post Cold-War World
By Gary Thomas Washington 13 October 2005

During the so-called Cold War, totalitarian regimes sought to block radio or TV broadcasts, except the ones they controlled. The Cold War is over, but those jamming efforts continue in some parts of the world. VOA Correspondent Gary Thomas reports from Washington on the 21st century battle of the airwaves.

Authoritarian governments still try to silence criticism and unfavorable news coverage in their countries by the age-old expedient of throwing critics in jail and shutting down their publications. But what does today's autocrat do about broadcasts being beamed into his country from sources outside his reach?

Simple. He jams them.

A longtime researcher on international broadcasting at the Voice of America, Kim Elliott, says the methods of jamming radio broadcasts are still much the same as they have been, even with new technologies.

"It is simply a matter of putting a noxious signal on the same frequency as the broadcaster that is trying to get into the country. And it was that way during World War II, it was that way during the Cold War, and it is still that way. If you tune across your short-wave radio, you will hear a raucous noise on one frequency, and you will hear the hapless international radio broadcaster in the background trying to get into the country," he said.

The result is rather like being in a crowded room watching a sporting event, with the cheering so loud that it is almost impossible to hear the person sitting right next to you.

Free speech advocates have always condemned jamming as an attempt to cut off the uninterrupted flow of information. Kenneth Tomlinson, the chairman of the U.S. government's Broadcasting Board of Governors that oversees VOA, Radio Free Asia, and other government-sponsored broadcast entities, has said it is illegal, and interferes with the free and open flow of international transmissions.

Experts say that, ironically, newer broadcast technologies, such as television, are actually easier to jam than old-fashioned short-wave radio, simply because radio can air on so many different frequencies at once.

Broadcast researcher Kim Elliott says jamming TV signals, especially from satellites, is relatively simple.

"Of all the media available to international broadcasting, short-wave is the most difficult to interdict. And that is because of the physics of transmission at short-wave frequencies," he said. "Signals from more distant transmitters come through better than signals from transmitters closer up. Television transmissions travel much shorter distances, and so those are much easier to jam. Or, if they are from a satellite, they are easy to jam because it only requires a few watts [of power]. And it does not have that kind of immunity [from jamming] that short-wave has."

Asia specialist Vincent Brossel, with the French media research group Reporters Without Borders, says radio still remains the main source of information for many people around the world.

"The radio is something like the most democratized and the most popular media in the world, due to the fact that many people cannot read, or do not have any access to Internet," he said. "The only way to touch millions, or billions of people around the world is radio."

Analysts say this is why China has become the biggest practitioner of international radio jamming in the post-Cold War world.

Mr. Brossel says Western firms, such as the French firm Thales', have sold broadcast equipment to China that also can be used for jamming.

"What is very interesting is that some Western companies are selling technology to the Chinese, and Chinese are selling technology for jamming to some Third World countries," he said. "So, it means that, just for business reasons, foreign companies like Thales' are helping the Chinese government to prevent millions, or billions of listeners from getting some free and independent radio programs."

Thales' officials have declined to comment on the company's sales. An American firm, Continental Electronics, also has sold transmission equipment to China, and to VOA, Radio Free Asia, and Taiwan, as well.

Experts say the term "jamming equipment" is really a misnomer, since a transmitter is something of a two-edged sword that can not only be used to broadcast, but can be easily converted to jam broadcasts.

Although Iran's theocratic government officially bans satellite television and has jammed foreign broadcasts, including those of exile Persian-language stations, the jamming has been sporadic, and is usually conducted during elections and other political events. Azadeh Moaveni, an Iranian-American journalist, who has reported from Iran, says the reality is different than official policy.

"Satellite television is technically banned," she said. "It is implicitly tolerated. And you could, I think, say comfortably that the majority of the country has access to satellite news."

Sometimes political jamming is tried as well.

Eutelsat, a European satellite operator, earlier this said it would not renew its contract to carry the signal of a new language broadcast outlet called New Tang Dynasty TV, or NTDTV Its links to the Falun Gong group, which is banned in China, earned it official Chinese displeasure. Mr. Brossel of Reporters Without Borders said Eutelsat was under what he called "tremendous pressure" from China to cancel the NTDTV contract. But last month Eutelsat agreed to renew it.

Pentagon Jams Web, Radio Links of Taliban

By YOCHI J. DREAZEN and SIOBHAN GORMAN

WASHINGTON -- The Obama administration is starting a broad effort in Pakistan and Afghanistan to prevent the Taliban from using radio stations and Web sites to intimidate civilians and plan attacks, according to senior U.S. officials.

Associated Press

A U.S. soldier patrols Afghanistan's Korengal Valley. The U.S. is adding operations involving radio and the Web to its efforts against the Taliban.

As part of the classified effort, American military and intelligence personnel are working to jam the unlicensed radio stations in Pakistan's lawless regions on the Afghanistan border that Taliban fighters use to broadcast threats and decrees.

U.S. personnel are also trying to block the Pakistani chat rooms and Web sites that are part of the country's burgeoning extremist underground. The Web sites frequently contain videos of attacks and inflammatory religious material that attempts to justify acts of violence.

The push takes the administration deeper into "psychological operations," which attempt to influence how people see the U.S., its allies and its enemies. Officials involved with the new program argue that psychological operations are a necessary part of reversing the deterioration of stability in both Afghanistan and Pakistan.

The Taliban and other armed groups have carried out a wave of attacks in the two countries. U.S. officials believe the Taliban enjoy an advantage by being able to freely communicate threats and decrees.

In Pakistan, Taliban leaders use unlicensed FM stations to recite the names of local Pakistani government officials, police officers and other figures who have been marked for death by the group. Hundreds of people named in the broadcasts have later been killed, according to U.S. and Pakistani officials.

"The Taliban aren't just winning the information war -- we're not even putting up that much of a fight," said a senior U.S. official in Afghanistan. "We need to make it harder for them to keep telling the population that they're in control and can strike at any time."

The new efforts were described by an array of U.S. officials, several with firsthand knowledge of the technologies and tactics used to block the radio stations and Web sites. The Pentagon, the Joint Chiefs of Staff and the Central Intelligence Agency declined to comment.

Psychological operations have long been a part of war, famously in World War II when "Tokyo Rose" broadcast English-language propaganda to Allied troops. More recently, some militaries have used high-tech methods. During the December-January war in Gaza, Israeli forces sent cellphone text messages to alert Palestinian civilians to impending strikes and encourage them to turn against the militant group Hamas.

The Obama administration's recently released strategy for Afghanistan and Pakistan calls for sending 4,000 U.S. military trainers to Afghanistan and sharply expanding economic aid to Pakistan. The U.S. may also provide radio-jamming equipment to the Pakistani government, according to officials familiar with the plans.

U.S. Army soldiers from 1st Infantry Division set up a ladder by a watch tower at an operation post in Nishagam, Afghanistan's eastern Kunar province.

The new push reflects the influence of Gen. David Petraeus, who runs the military's Central Command and has long been a major proponent of using psychological operations to reduce popular support for armed Islamist groups.

Another supporter, Richard Holbrooke, the administration's special envoy for Pakistan and Afghanistan, publicly alluded to the new program late last month. He told reporters there were 150 illegal FM radio stations in Pakistan's Swat Valley, which allowed militants to go "around every night broadcasting the names of people they're going to behead or they've beheaded."

Mr. Holbrooke likened the Taliban radio stations to Rwanda's Radio Mille Collines, a virulently sectarian broadcaster widely believed to have helped fuel the Rwandan genocide. The U.S. considered jamming the station in the 1990s, but ultimately chose not to.

"Nothing has been done so far" about impeding the Taliban communications, Mr. Holbrooke said. "We have identified the information issue ... as a major, major gap to be filled."

Psychological operations can be controversial. In Iraq, the Pentagon at one point ran a program that paid Iraqi journalists to run articles and opinion pieces supportive of U.S. war aims and the Iraqi central government. Critics called it government-funded propaganda, while the Bush administration defended the effort.

Henry A. Crumpton, a former State Department counterterrorism chief who led the CIA's Afghanistan campaign in 2001 and 2002, warned against relying too heavily on high-tech solutions such as disrupting militant radio broadcasts. "Those can be very effective, but they're -- underscore -- short-term tactics," he said.

Still, many military officials believe that stabilizing Afghanistan and Pakistan requires gradually diminishing the Taliban's public standing while simultaneously building popular support for more moderate local political and religious institutions allied with the U.S.

"It's not an issue of trying to persuade your average Pakistani farmer to love the U.S.," a U.S. official said. "The idea, frankly, is to muddy the water a bit."

As part of this push, the U.S. has started U.S.-funded radio stations in many rural parts of Afghanistan. In one example, Army Special Forces teams in eastern Paktia, a restive Afghan province that abuts the Pakistani frontier, put on air a radio station late last year called "the Voice of Chamkani," referring to the village where the U.S. base is located, and distributed hundreds of radio receivers.

According to an account in the current issue of "Special Warfare Magazine," an Army publication on special operations, the U.S.-run radio station has worked to build support for the Afghan national government by highlighting local development projects that were approved by Kabul.
