North Atlantic (NAT) MWARA Profile and Frequencies

Our good friend Tony Roper posted the following list of North Atlantic (NAT) Major World Air Route Area (MWARA) frequencies on the UDXF list. I have added some additional material from my personal files and monitoring to round out this profile. If you are a military monitor, these frequencies are a great playground in the HF spectrum to catch possible mil aircraft activity. All frequencies are in kHz and mode is USB.

The Spectrum Monitor Review of the International Call Sign Handbook, 4th Edition

Blog Editor Note: This is a review of my new e-book that appeared in the May edition of The Spectrum Monitor e-zine. The Spectrum Monitor ® is published monthly by Ken Reitz KS4ZR at 1403 Holland Creek Road, Louisa, Virginia 23093. You can order your subscription to TSM at http://www.thespectrummonitor.com/.

New International Call Sign Handbook: Government and Military EditionBy Larry Van Horn N5FPW
Teak Publishing $6.99
Fourth Edition Kindle e-book 608 pages
Reviewed by Ken Reitz KS4ZR

Anyone who had read Monitoring Times magazine over the last few decades will be familiar with the topic of government and military radio call signs that appeared every month in the Milcom column, written by Larry Van Horn N5FPW. While MT ceased publication with the December 2013 issue, Larry maintained his interest in this subject and has just released the massive fourth edition of the International Call Sign Handbook (Government/Military Edition).

And, if you’ve been reading Hugh Stegman and Mike Chace-Ortiz’s columns in TSM, you’ll know that there are hundreds of frequencies on which you might hear any of these call signs. You can’t tell the players without a scorecard and Larry’s just published the definitive call sign scorecard.

At more than 600 pages, he has left nothing out. And, if you are not familiar with this fascinating subject, he includes a thorough tutorial on the subject to bring you up to speed. Call signs for every branch of the US military, known and arcane federal agencies, and many nongovernmental organizations are also listed. He has also included international call signs for other countries.

You’ll also learn how to set up your listening post to be able to monitor Mode-S ADS/B, a data stream that is sent automatically by most civilian and military aircraft, that IDs each craft as it comes within communications reach of your receiver; a hobby within the air monitoring hobby. Larry includes active links to all the websites you’ll need to go to for software downloads and detailed instructions on tuning in.

It’s difficult to emphasize what a bargain this book is: $6.99 (that was the cost of one issue of Monitoring Times, if you could find it on the bookstore shelves!) for 600 pages of military and federal call signs (in its last year the entire MT magazine was only 62 pages each month and the Milcom column was only two pages each month!).
This book has an active Table of Contents that makes finding your way around in this enormous publication a breeze.

The International Call Sign Handbook is available only as a Kindle e-publication, but you don’t need a Kindle product, iPad, or smartphone to read this publication. Any desktop or laptop computer can display any Kindle e-book. Just download the free app for your device, order the book and start reading.

International Call Sign Handbook e-book now available at Amazon

The reviews are in and the International Call Sign Handbook is a huge hit.

5 Star Rating 100% rating on the deal of the century! By Barry L. Williams
After 20 years of reading the columns, reviews, and advice of Larry van Horn in Monitoring Times magazine, it was a no brainer that he is an expert on military/civilian communications on shortwave and high frequency radio. He has always been the go-to expert for what military and civilian radio calls you were hearing on the HF/SW frequencies. Now, the decades of experience and research is in his new book. It has an excellent table of contents itemized by service, country, etc. Each entry is clickable for navigation. And, the list is huge! This is the most complete list of units, boats, aircraft, units, etc that I've seen. It is also more than just a list as the book also explains the organizations and services with details and explanations.

The other great thing about this must have book is the price- $6.99. There is no reason for anyone to not have this book at that price. This is the first book with this much information that I've seen that doesn't cost $25 and up. There just is no reason to not buy it right now.  

5 Star Rating Updated classic By Hugh D Stegman, The Spectrum Monitore-zine columnist
You won't go wrong with this one. Larry is the go-to guy for this kind of information in the hobby, and his lists have always been full of names and call signs that you'll actually hear on the air, plus all manner of other arcane military codes and rotating IDs. I don't know how I'd identify most military stations without it. At this garage sale price, it may be the best deal in utility radio.
 
Ask any radio monitor what information they consider important during any monitoring session, and usually two items will top their list: frequencies and call signs. If you can hear activity on a particular frequency, unless you can fully identify the participants transmitting on that frequency, you can’t fully appreciate or document the traffic you are hearing.
 
With millions of radio stations furnishing a variety of communication services throughout the world, it is necessary that their transmissions carry distinctive call signs or identifiers. Call signs have a four-fold purpose: They may identify the nationality of the station, the agency operating a particular station, the type of station, and the identity of each individual station being heard on the monitored frequency.
 
The need for station identifications/call signs can easily be illustrated here in the United States, which leads all other countries in the use of the radio spectrum, that now has some 85 different kinds of radio services operated by the government, military and civilians entities, providing air, sea, land and space communication services. There are hundreds of thousands of stations on the air and call signs and other forms of identification help the radio monitor sort through the various stations that are heard.
 
A call sign is defined as any combination of alphanumeric characters or phonetically pronounceable characters (trigraph), which identifies a communications facility, a command, an authority, an activity or unit. To aid the radio monitor in their listening endeavors, the International Call Sign Handbook series of books/e-books has been published.
 
 
 
Teak Publishing is pleased to announce their latest Kindle e-book -- the fourth edition of International Call Sign Handbook by Amazon Bestselling author Larry Van Horn, N5FPW. This e-book represents the most comprehensive collection of military and government station identifications ever published for the radio listening hobby. It is the result of year’s research, study and monitoring the HF/VHF/UHF radio spectrum, by the author. Many different radio monitoring disciplines have been used to compile the listings in this book. If you monitor the HF, VHF or UHF radio spectrum, there is something in this book for you.
 
The information presented in this book has also been gathered through personal correspondence, material published in the former Monitoring Times magazine, various radio publications, newsletters, public domain government and private internet web sites, but most have been gathered the old fashioned way via on-the-air monitoring. In addition, we have received generous support and contributions from many individuals in the radio hobby.
 
In addition to international and military/government tactical call signs, other types of identifiers such as Automatic Link Establishment (ALE) and Mode-S aircraft addresses have been included in this e-book. There is a chapter that had basic introductory material, as well as chapters devoted to call sign / words used by the Department of Defense including the US. Air Force, U.S. Army, U.S. Navy and Marine Corps. There are sections that cover the various Military Auxiliary Radio Services and the U.S. Air Force Civil Air Patrol auxiliary service.
 
There is also a chapter that covers call signs and ALE identifiers for the U.S. Coast Guard service. Sections in that chapter include a Coast Guard aircraft fleet list, miscellaneous U.S. coast guard calls, and also their international call signs.
 
Another large chapter covers various U.S. Government call signs. Sections in this chapter include the U.S. Custom and Border Patrol COTHEN radio system and ALE address list, plus call signs from the following department and agencies - Department of Commerce (DOC), Department of Energy (DOE), Department of Homeland Security (DHS), Department of the Interior (DOI), Department of the Interior (DOI) Bureau of Indian Affairs, Department of Justice (DOJ), Department of State, Department of Transportation, Department of Veterans Affairs (DVA), Drug Enforcement Administration (DEA), Environmental Protection Agency, Federal Aviation Administration, Federal Bureau of Investigation (FBI), Federal Communications Commission, Federal Emergency Management Agency (FEMA), Federal Highway Administration (FHWA), General Services Administration (GSA), Health and Human Services, Housing and Urban Development Department (HUD), Miscellaneous Listings, National Aeronautics and Space Administration, National Communications System (NCS), and U.S. Marshal Service (USMS) service.
 
One of the larger chapters is devoted to an international / worldwide call signs list. We have a sampling of government and military call signs from 75 counties and international agencies.
 
The latest craze in aircraft military is decoding Mode-S/ICAO24 radio signals and is included in this book. Our list in this edition covers primarily government / military aircraft and introductory material on Mode-S monitoring.
The last chapter of this book contains a large list of resource information, useful in interpreting the individual entries listed in the book. Sections on U.S. Navy ship/squadron classifications; U.S. Coast Guard cutter designators; a massive list of abbreviations and acronyms that appear in the book; a comprehensive country abbreviation list; and the latest Table of Allocations of International Call signs from the International Telecommunications Union (ITU) are included in the last chapter on the e-book.
 
The Teak Publishing 4th International Call Sign Handbook is now available for purchase worldwide from Amazon.com at http://www.amazon.com/dp/B00VV7NR1U.
 
The price for this e-Book edition is US$6.99. This book is being released internationally.

Russia regains control of radio facility in Cuba's Lourdes base

This article originally appeared on the Sputnik News website on July 16. 2014.

Archive. Photo: RIA Novosti
Russia has retrieved the main Soviet radio interception facility – the signals intelligence center in Cuban Lourdes, the Kommersant newspaper wrote on Wednesday. "The decision to return to Cuba can be explained by Russia's long strengthened financial capabilities, as well as cooling of relations with the US," sources in the Russian power structures said.

The base on the territory of the USSR's and Russia's most consistent ally was built in 1962 and since then, has been repeatedly renewed, satisfying the need for interception of information from American communication satellites, ground-based telecommunications cables and wiretapping the NASA's Mission Control Center on Cape Canaveral. This is facilitated by its location in the Western part of the island, only 250 kilometers from Florida's coast.

In 2001, unexpectedly for the Cubans, Russia refused to use the center, which, according to the then Minister of Defense of Cuba Raul Castro, at the moment of the collapse of the USSR provided up to 75 percent of intelligence information.

The center was closed after Vladimir Putin visited it together with Fidel Castro in December, 2000, and while speaking to the staff stated "the importance of the facility for ensuring Russia's security, the need to support its activities and development prospects." But a year later, head of the Russian General Staff Anatoly Kvashnin made a statement that the center in Lourdes was not important, was costly, and its functions could be easily transferred to modern satellites.

Cubans were able to maintain the center, having created a scientific center on its basis. Since 2004, after the deterioration of relations with the US, Russia began to consider the possibility of returning to Cuba. The talks were sharply intensified at the beginning of this year and successfully completed during Putin's visit to Havana.

US warship heads to Yemeni waters!

The Associated Press this morning is reporting that US Navy warships are headed for the waters off Yemen.

"In a stepped-up response to Iranian backing of Shiite rebels in Yemen, the Navy aircraft carrier USS Theodore Roosevelt is steaming toward the waters off Yemen to beef up security and join other American ships that are prepared to intercept any Iranian vessels carrying weapons to the Houthi rebels.

"Navy officials said Monday that the Roosevelt was moving through the Arabian Sea. A massive ship that carries F/A-18 fighter jets, the Roosevelt is seen more of a deterrent and show of force in the region.
 
"The U.S. Navy has been beefing up its presence in the Gulf of Aden and the southern Arabian Sea in response to reports that a convoy of about eight Iranian ships is heading toward Yemen and possibly carrying arms for the Houthis. Navy officials said there are about nine U.S. warships in the region, including cruisers and destroyers carrying teams that can board and search other vessels."

NATO AWACS Investigates Baltic Skies


How to Spot a Russian Bomber

 
Found this interesting article in my stack of stuff from back in the middle of February posted to the BBC News blog (http://www.bbc.com/news/blogs-magazine-monitor-31537705). Given the current situation, this might be helpful to have around.


How to Spot a Russian bomber

Two Russian bombers have been escorted from near UK territory - the latest in a series of similar incidents. How easy is it to spot a Russian plane, asks Jon Kelly.

Plane spotter's guide

The Ministry of Defence insists that the Russian aircraft did not enter British airspace, which extends 12 nautical miles from the nation's coast. But it says they were inside the UK's "area of interest", and the RAF scrambled Typhoon jets to intercept them. If the MoD's account is accurate, they may have been flying too far away for ordinary plane spotters to detect them - although a woman in Cornwall claims she saw them flying inland.

Each was a Tu-95 MS, also known by its NATO reporting name "Bear-H", a four-engine long-range bomber, equipped with turboprop-driven propellers and set-back wings that give it an unmistakable silhouette.

The Bear Bomber
The TU-95 Bear Bomber
The most noticeable thing about the Bear, the earliest iteration of which entered service in 1956, is the almighty racket it makes. Its contra-rotating propellers spin faster than the speed of sound, creating their own sonic boom, making it one of "the loudest combat aircraft ever built", says Justin Bronk of the Royal United Services Institute. The Bear, which typically carries six or seven crew members, is not the fastest aircraft in the Russian fleet, reaching speeds of only about 575 mph (920 km/h). But it is regarded as one of the most reliable, says Bronk, which helps account for its longevity.

Another bomber you might expect to see just outside British airspace is the Tu-160, known as the Blackjack, two of which were intercepted by RAF Tornado F3 fighters off the Scottish coast in 2010. Unlike the Bear, the Blackjack is capable of supersonic speeds of up to 2,200km/h. "It's essentially a heavier and faster equivalent of the American B1B Lancer," says Bronk. It also has a longer range and can carry more nuclear-capable missiles. An upgraded version of the TU-160 made its maiden flight in November 2014.

Then there's the Tu-22M3 strategic bomber, which is also supersonic and nuclear-capable. "It's not as big as the Bear and the Blackjack," says Bronk. "Its closest Western equivalent is the F-111." Its variable-sweep wing allows it to take off quickly and fly at very low altitudes. There are thought to be over 100 TU-22Ms in service in the Russian fleet.

The MiG 31 interceptor

Sometimes Bears are escorted by supersonic MiG-31 interceptors, says Bronk. Among the world's fastest combat aircraft, they are equipped with onboard radar that can track 24 airborne targets and attack six at a time. But Bronk says: "Although they are extremely fast and carry powerful radar, they are a essentially an evolution of a very old design, the MiG-25, and are no match for the RAF's Typhoons in air-to-air combat."

Plane spotter's guide
The incident in Cornwall is unlikely to be the last time radar operators detect Bears. There was a similar incident in January when two Bear bombers were escorted by RAF jet after causing what the Foreign Office called a "disruption to civil aviation". The RAF intercepted Russian aircraft on eight occasions in 2014, and the same number of times in 2013, according to MoD figures released under the Freedom of Information Act.

"Bear raids" just outside British airspace were a common occurrence during the Cold War, sometimes taking place every week, says defence analyst Paul Beaver. Back then, he says, the intention was to test the RAF's reaction time. Their frequency lessened in the final years of the Soviet Union and stopped altogether when the Berlin Wall fell. Under Vladimir Putin's leadership, however, they have resumed. Yesterday, Prime Minister David Cameron said he suspected the Russians were "trying to make some sort of a point", and Bronk agrees. "Essentially, it's rattling the sabre."

Russians intercept US reconnaissance plane - Updated Story

A Russian Sukhoi Su-27 fighter flies in international airspace near the Baltic States in this photograph taken on June 17, 2014 and received via Britain's Ministry of Defence (MoD) in London on June 18, 2014. Photo courtesy of RAF/MoD.
The AP is reporting the U.S. is protesting an intercept of a U.S. reconnaissance plane by a Russian fighter jet last week, calling it "unsafe and unprofessional" amid what it views as increasingly aggressive air operations by Moscow.

The Pentagon says that a U.S. RC-135U plane was flying in international airspace north of Poland. U.S. officials say a Russian SU-27 fighter intercepted the U.S. aircraft at a high rate of speed from the rear, and then proceeded to conduct two more passes using "unsafe and unprofessional maneuvers" in close proximity.

It isn't the first time the U.S. has protested to Moscow what it considered to be an unsafe intercept. Last April, a Russian fighter jet intercepted a U.S. reconnaissance plane in international airspace over the Sea of Okhotsk.



Blog Editor's Note: Media reports indicate that this event occurred on 7 April 2015. A quick check of Mode-S logs for that day indicated the only RC-135U airborne that day was RC-135U 64-14849 (Hex code AE01D5) with a mode-s call sign of Telex 97 and yes it was over Poland/Estonia/Finland area between 1000-1300 UTC. Interestingly, based on the database it looks like that aircraft did not fly the next day. This aircraft is still in theater today and has flown the last 3 days using a mod-s call sign of Cuppy 50. Time to pay closer attention to those foxtrot messages.

RC-135U Combat Sent

Mission
The RC-135U Combat Sent provides strategic electronic reconnaissance information to the president, secretary of defense, Department of Defense leaders, and theater commanders. Locating and identifying foreign military land, naval and airborne radar signals, the Combat Sent collects and minutely examines each system, providing strategic analysis for warfighters. Collected data is also stored for further analysis by the joint warfighting and intelligence communities. The Combat Sent deploys worldwide and is employed in peacetime and contingency operations.

Features
All RC-135U aircraft are equipped with an aerial refueling system, giving it an unlimited flying range. Communication equipment includes high frequency, very high frequency, and ultra high frequency radios. The navigation equipment incorporates ground navigation radar, a solid state Doppler system, and an inertial navigation system that merges celestial observations and Global Positioning System data. Although the flight crew stations are similarly configured, the reconnaissance equipment is slightly unique within each airframe.

The aircraft are identified by their distinctive antennae arrays on the "chin" and wing tips, large cheek fairings, and extended tail.

Crew composition includes two pilots, one navigator, two airborne systems engineers, and a minimum of 10 electronic warfare officers, or "Ravens," and six or more electronic, technical, and area specialists.

Background
There are only two Combat Sent aircraft in the Air Force inventory and both are assigned to the 55th Wing at Offutt AFB, Neb. The RC-135U aircraft are manned by Air Combat Command crews from the 45th Reconnaissance Squadron and the 97th Intelligence Squadron (of the Air Force Intelligence, Surveillance and Reconnaissance Agency). The Combat Sent is composed of a wide variety of commercial off-the-shelf and proprietary hardware and software. Its current configuration allows for both manual and automatic analysis of electronic signals. By combining manual systems with the Automatic Electronic Emitter Locating System, Ravens and intelligence specialists can simultaneously locate, identify, and analyze multiple electronic signals.

The Combat Sent records these signals for future reference or for extensive analysis by electronic systems theorists. Any information garnered from the data will help determine detailed operating characteristics and capabilities of foreign systems. Evasion techniques and equipment are then developed from this knowledge that will detect, warn of, or defeat these electronic systems.

US aerospace command moving comms gear back to Cold War bunker

Blog Editor's Note: YahooNews has picked up the following AFP story. HF radio monitors should keep an eye on the following frequencies for activity related to this story (Mode ALE/USB): 4950.0 6770.0 7718.5 7990.0 9350.0 10800.0 12090.0 14550.0 kHz



Washington (AFP) - The US military command that scans North America's skies for enemy missiles and aircraft plans to move its communications gear to a Cold War-era mountain bunker, officers said.
The shift to the Cheyenne Mountain base in Colorado is designed to safeguard the command's sensitive sensors and servers from a potential electromagnetic pulse (EMP) attack, military officers said.

The Pentagon last week announced a $700 million contract with Raytheon Corporation to oversee the work for North American Aerospace Command (NORAD) and US Northern Command.

Admiral William Gortney, head of NORAD and Northern Command, said that "because of the very nature of the way that Cheyenne Mountain's built, it's EMP-hardened."

"And so, there's a lot of movement to put capability into Cheyenne Mountain and to be able to communicate in there," Gortney told reporters.

"My primary concern was... are we going to have the space inside the mountain for everybody who wants to move in there, and I'm not at liberty to discuss who's moving in there," he said.

The Cheyenne mountain bunker is a half-acre cavern carved into a mountain in the 1960s that was designed to withstand a Soviet nuclear attack. From inside the massive complex, airmen were poised to send warnings that could trigger the launch of nuclear missiles.

But in 2006, officials decided to move the headquarters of NORAD and US Northern Command from Cheyenne to Petersen Air Force base in Colorado Springs. The Cheyenne bunker was designated as an alternative command center if needed.
That move was touted a more efficient use of resources but had followed hundreds of millions of dollars worth of modernization work at Cheyenne carried out after the attacks of September 11, 2001.

Now the Pentagon is looking at shifting communications gear to the Cheyenne bunker, officials said.

"A lot of the back office communications is being moved there," said one defense official.

Officials said the military's dependence on computer networks and digital communications makes it much more vulnerable to an electromagnetic pulse, which can occur naturally or result from a high-altitude nuclear explosion.

Under the 10-year contract, Raytheon is supposed to deliver "sustainment" services to help the military perform "accurate, timely and unambiguous warning and attack assessment of air, missile and space threats" at the Cheyenne and Petersen bases.
Raytheon's contract also involves unspecified work at Vandenberg Air Force Base in California and Offutt Air Force Base in Nebraska.

The Associated Press is reporting that Iran is dispatching Iranian naval ships to Yemen coastal waters.



"Iran dispatched a naval destroyer and another logistic vessel on Wednesday to waters near Yemen as the United States quickened weapons supply to the Saudi-led coalition striking rebels there, underlining how foreign powers are deepening their involvement in the conflict.
 
"Iran's English-language state broadcaster Press TV quoted Rear Adm. Habibollah Sayyari as saying the ships would be part of an anti-piracy campaign "safeguarding naval routes for vessels in the region."
