BY BRIAN LATELL
SPECIAL TO THE MIAMI HERALD
For 16 years, Ana Belen Montes spied for Cuba from increasingly responsible positions at the Defense Intelligence Agency. If Havana has ever run a higher level or more valuable mole inside the American defense establishment, that has never been revealed.

When she was arrested in late September 2001, Montes was about the equivalent in rank of a colonel. She had access to sensitive compartmented intelligence. Strangely, for one so openly enamored of Fidel Castro, her superiors considered her one of the best Cuba analysts anywhere in government.

Despite the importance of her case, some of the most tantalizing questions about her spying have never been publicly answered. Could the calamity of her treason have been avoided? What was learned about Cuban intelligence tradecraft? How was she discovered? And, of enduring concern, did she work with other American spies thus far undetected or not prosecuted?

Thanks to researcher Jeffrey Richelson and the National Security Archive, new light has finally been shed on the Montes case. Because of their efforts, a 180 page study completed by the Department of Defense Inspector General in 2005 has recently been declassified. It is heavily redacted; many pages, including the CIA’s extensive comments, blacked out. Yet, a quantity of surprising new details are now on the public record.

Montes’s decision to spy for Cuba was “coolly deliberate.” Enticed by a Cuban access agent in Washington, they traveled together to New York in December 1984. Montes met with intelligence officers posted under cover at the Cuban mission to the United Nations.

She “unhesitatingly agreed” to work with them and travel clandestinely to Cuba as soon as possible. The following March, she went there via Spain and Czechoslovakia. The Pentagon report does not state the obvious: while there, she must have received specialized training in intelligence tradecraft.

Then, with Cuban encouragement, she applied for a job at DIA. A standard background investigation was conducted, but we now know that serious concerns about her suitability were raised. Without elaboration, the Pentagon report indicates that they included “falsification of her Master of Arts degree from Johns Hopkins (University) and her trustworthiness.”

DIA did not require applicants to submit to a pre-employment polygraph exam. So, Montes, a trained Cuban espionage agent with a problematic past was cleared and hired. She began her double duties in September 1985.

After her arrest, Montes insisted that she had the “moral right” to provide information to Cuba. In her view, she did not work for Cuba, but with Cuban officials. They felt “mutual respect and understanding” she thought, as “comrades in the struggle.”

The Cubans were skilled in manipulating and controlling her. She told interrogators after her apprehension that she considered herself the equal of her “Cuban comrades, not a menial espionage tool.” They let her believe she “maintained significant control,” although she consistently left “security matters, including meeting site security, countersurveillance, and transmission security” to her handlers.

Montes said they were “thoughtful, sensitive to her needs, very good to me.” They went to “special lengths to assure her they had complete confidence in her.” They allowed her a long, loose leash, easier because they were not paying for her extraordinary services.

Initially in New York, and later at her request in the Washington area, she met with her handlers as often as once every two or three weeks, usually on weekends. Everything about her second covert trip to Cuba is redacted in the Pentagon report.

In 1991, Montes underwent a seemingly routine security reinvestigation. She was asked about foreign travel, and lied. Questioned about inaccuracies in her original application for employment, she confessed that she had misrepresented an incident in her past. Feigning innocence, Montes claimed that she “did not understand the seriousness of being truthful and honest at the time.”

Her questionable case was then reviewed at a higher level. The adjudicator reported that “while Montes seemed to have a tendency ‘to twist the truth’ to her own needs and her honesty was still a cause of concern, adverse security action was unlikely.” Again, she had slipped through. Her high level clearances were recertified.

Soon after, she brazenly submitted a freedom of information request for her own government records. She must have been concerned that something adverse had been discovered. Investigative material was released. She gave the surprised Cubans copies.

She apparently visited Cuba a third time after being selected to participate in the prestigious Director of Central Intelligence “Exceptional Analyst Program” in 1992. This time her travel to the island, purportedly to conduct research, was legal.

In 1996, she was questioned by a DIA special agent after another DIA employee reported concerns about her. Serious doubts were raised about her veracity, but the allegations could not be substantiated.

None of this seems to have contributed to her eventual unmasking. So, how was she discovered? Surprisingly, revealing information seeps through the Pentagon’s report. “We got lucky,” a counterintelligence official observed. An entirely blacked-out section entitled “Serendipity” suggests the same.

By April 1998, a coordinated search for a Cuban spy was underway, according to the report. At first it was thought most likely the quarry was a CIA employee. Investigators were following a crucial clue: the unknown spy had apparently traveled to the Guantanamo naval base as Montes had apparently done on official DIA business.

The breakthrough had seemingly come earlier, however. According to the Pentagon report, Montes was informed shortly after her arrest that investigators “had information from a senior official in the Cuban intelligence service concerning a Cuban penetration agent that implicated Montes.” It appears that this information propelled the investigation that resulted in her arrest.

Who was this mysterious, previously unacknowledged source? From the language of the Pentagon report, it was probably not a defector, but more likely a renegade or compromised Cuban intelligence officer. If so, Montes was done in by one of her own so-called “comrades.”

Did she work with other American spies? The report is ambiguous; it states that after the terrorist attacks on September 11, 2001 pressure intensified to arrest Montes. The FBI preferred to wait, however, in order “to monitor Montes’s activities with the prospect that she may have eventually led the FBI to others in the Cuban spy network.”

Did government censors inadvertently confirm the existence of a larger spy ring? If in fact there was evidence of one, it may be a long time before more is known.

It is now clear, however, that Montes’s apprehension was not just the result of excellent intelligence work. She told investigators after her arrest that a week earlier she had learned that she was under surveillance. She could have decided then to flee to Cuba, and probably would have made it there safely.

But she said that “she couldn’t give up on the people (she) was helping.” Montes is serving a 25 year prison sentence.

I'm not as worried about an EMP or a blast from the Sun, but more of gov't monitoring or gov't firewalls.

Listen to some foreign station via the Internet might just get you on a watch list or rounded up for being an enemy of the state.

If the gov't firewall is working (e.g. the Great Firewall of China), then you're only allowed to listen to what the gov't allows.

At least with SW, jamming was usually partially effective and at substantial cost, and they can't block all frequencies. A firewall is relatively easy, cheap and more effective.


Even if you have Internet and able to stream, what about data caps and the recurring cost of the Internet connection? Shortwave radio is cheaper.


I'll keep my SW radios. Streaming stations through TOR is crappy.

QSLs Received / Re: WWV 25 MHz QSL
« on: August 01, 2014, 0214 UTC »
Received mine today, for receiving 10, 15, and 25 MHz on 06 July 2014.

Interesting tidbits:

The one I received has a s/n around 280 greater than yours. The one I received on 5 Sept 1991, is about 2900 earlier than that.

Assuming no gaps and serial numbers increased normally, that's approximately 126 QSL's per year during the past 23 years, yet in the past 3 months, they put out ~280. Perhaps due to 25 MHz.

The card I received today is the exact same style as that received in 1991, and John B Milton is still the engineer in charge as he was in 1991. They must have a huge stack of these things... It still refers to National Bureau of Standards, instead of National Institute of Standards and Technology.

South Korea’s latest attempt to sway the minds of the North Korean people looks like a dud before it’s even begun.

This month, the South Korean military begins regular programming on a new shortwave radio station aimed at the DPRK, but the selection of frequency, low transmitter power and aggressive jamming means few if anyone in the DPRK can probably hear it.

Voice of Freedom began several years ago on FM along the border. The use of FM hobbled the station because the signals typically only travel a few tens of kilometers and are susceptible to being blocked by the many hills in the area.

In May Voice of Freedom began test broadcasts began on shortwave, which can reach much further because the signals bounce off the ionosphere and come back down far from the transmitter site.

It’s the only reliable way to get regular radio programming into North Korea and is used by several broadcasters, including outlets like Radio Free Asia, which use high power transmitters as far away as the Northern Mariana Islands to get their signal into the DPRK.

Radio stations can choose their own spot on the shortwave dial and, while it’s less crowded than it used to, the frequency still needs to selected with care. It not only needs to avoid other stations, which come on and off the air at different times of day, but to match the expected atmospheric conditions for the time of year and the distance to be covered.

Voice of Freedom turned up on 6,135kHz, well inside the most crowded shortwave band in East Asia. This means it not only has to overcome North Korean jamming, which is already aggressively blocking its signal most days, but it also has to compete with more powerful stations.

“I don’t know who or why they picked this frequency,” said Jamie Labadia in an email to North Korea Tech. Labadia is a U.S.-based shortwave engineer who was contracted by the South Korean military to build the station.

“Not only is it the most crowded band one could pick in the evening, it is also rather high in frequency for the short distance to the target area,” he said. The frequency was suitable for the daytime, but at night the signal was probably bouncing right over a large part of the southern portion of North Korea.

In the couple of weeks before North Korea caught on to the broadcasts, they were being heard across Asia and in the United States, but no more. North Korean jamming, similar to that faced by Radio Free Asia, Voice of America, KBS and several other broadcasters, has been wiping out the signal.

“I know the pulse is destroying us,” Labadia said to Glenn Hauser, author of the popular DXLD shortwave newsletter. “Pretty discouraging to go through all of these struggles, only to have it be for naught.”

Labadia said he had “tried to convince [the South Korean military] to use a second frequency, however as of now they are staying on 6135.”

Two stations run by South Korea’s National Intelligence Service use a series of transmitters on different frequencies to maximize their chances of getting through North Korea’s jamming blockade. As of now, it looks like Voice of Freedom won’t be doing the same so the station might be an exercise in frustration.

Here’s the broadcasting schedule, provided by Labadia to DXLD:

0800 to 0000 GMT / 1700 to 0900 local time

0300 to 0500 GMT / 1200 to 1400 local time

The station isn’t on air during work hours because foreign radio listening is typically done in secret, at home.

http://www.rawstory.com/rs/2014/07/25/nasa-solar-storm-in-2012-nearly-knocked-modern-civilization-back-to-the-18th-century/

By Agence France-Presse
Friday, July 25, 2014 15:55 EDT

Back in 2012, the Sun erupted with a powerful solar storm that just missed the Earth but was big enough to “knock modern civilization back to the 18th century,” NASA said.

The extreme space weather that tore through Earth’s orbit on July 23, 2012, was the most powerful in 150 years, according to a statement posted on the US space agency website Wednesday.

However, few Earthlings had any idea what was going on.

“If the eruption had occurred only one week earlier, Earth would have been in the line of fire,” said Daniel Baker, professor of atmospheric and space physics at the University of Colorado.

Instead the storm cloud hit the STEREO-A spacecraft, a solar observatory that is “almost ideally equipped to measure the parameters of such an event,” NASA said.

Scientists have analyzed the treasure trove of data it collected and concluded that it would have been comparable to the largest known space storm in 1859, known as the Carrington event.

It also would have been twice as bad as the 1989 solar storm that knocked out power across Quebec, scientists said.

“I have come away from our recent studies more convinced than ever that Earth and its inhabitants were incredibly fortunate that the 2012 eruption happened when it did,” said Baker.

The National Academy of Sciences has said the economic impact of a storm like the one in 1859 could cost the modern economy more than two trillion dollars and cause damage that might take years to repair.

Experts say solar storms can cause widespread power blackouts, disabling everything from radio to GPS communications to water supplies — most of which rely on electric pumps.

They begin with an explosion on the Sun’s surface, known as a solar flare, sending X-rays and extreme UV radiation toward Earth at light speed.

Hours later, energetic particles follow and these electrons and protons can electrify satellites and damage their electronics.

Next are the coronal mass ejections, billion-ton clouds of magnetized plasma that take a day or more to cross the Sun-Earth divide.

These are often deflected by Earth’s magnetic shield, but a direct hit could be devastating.

There is a 12 percent chance of a super solar storm the size of the Carrington event hitting Earth in the next 10 years, according to physicist Pete Riley, who published a paper in the journal Space Weather earlier this year on the topic.

His research was based on an analysis of solar storm records going back 50 years.

“Initially, I was quite surprised that the odds were so high, but the statistics appear to be correct,” said Riley.

“It is a sobering figure.”

Huh? / Re: What to Do with a Failed $5 Billion Experiment?
« on: July 24, 2014, 0144 UTC »
Repurpose it.

1. Send up multiple geostationary satellites that are stationed around the earth.  Point the laser at one of the satellites. It will split the beam and send it to its two neighboring satellites, and then those satellites split the beam and send them to its neighbors for a pair of beams circling (pair of beams for redundancy) the earth.

2. Those source beams will be split again, redirected, and widened to cover major parts of the earth below it. Experiment with different wavelength lasers to see impact of weather, clouds, atmosphere, and use whatever makes it through to the ground.

3. If the downlink laser isn't making it through the clouds, increase power to burn off the clouds.

4. Modulate the uplink laser beam, play music.

5. Profit.

Huh? / Re: SDRs vs Sun Spot Number
« on: July 20, 2014, 0057 UTC »
Well, its pretty clear from that graph that the SDRs are interfering with the sun creating them things. SDRs are unnatural and the sun knows it, so its denying us propagation.


jFarley has inspired an idea- Instead of tying an SDR to a boatanchor, what if instead, make an analog SDR with vacuum tubes? Not only may it appease the sun god, but would also survive an EMP (don't bring up the point that the computer & power grid wouldn't. Next step is an analog computer made from vacuum tubes. We've done that before, and can do it again in 2014, better...stronger...faster. ).

Yes... yes.... Analog SDR sends the data to the control unit, which is some form of embedded SDR s/w. Tuners, home entertainment systems, and car stereos. Portable radios may be a bit tricky, so need to invent better power source than chemical batteries.
 
The sunspots will return!

Equipment / Re: WWV receiver for ntpd time source
« on: July 19, 2014, 1658 UTC »
You're right, GPS better than HF since it can correct the delays, and right now I do not know what my HF propagation delay is. There's a formula that I can use to estimate it, but that's only an estimation.  The GPS/CDMA source is on the list as I want to measure the propagation delays from there to here instead of estimating it. Then can see how well it coincides with the formula, or more importantly, how much it varies by frequency, time of day & time of year.

Yeah, I agree that a reference standard on 6925 (or thereabouts) would be quite handy. I like that a lot. :)

Been wanting to use WWV for many, many years and never got around to it until now.

Discussion

Overview
Ten days ago, the sun was quite active and peppered with several large spots. Now the sun has gone quiet and it is nearly completely blank. It appears that the solar maximum phase for solar cycle 24 may have been reached and it is not very impressive. It looks as if this solar cycle is “double-peaked” (see below) which is not all that uncommon; however, it is somewhat rare that the second peak in sunspot number during the solar max phase is larger than the first. In fact, this solar cycle continues to rank among the weakest on record which continues the recent trend for increasingly weaker cycles. The current predicted and observed size makes this the smallest sunspot cycle since Cycle 14 which had a maximum of 64.2 in February of 1906. Going back to 1755, there have been only a few solar cycles in the previous 23 that have had a lower number of sunspots during its maximum phase. For this reason, many solar researchers are calling this current solar maximum a “mini-max”. Solar cycle 24 began after an unusually deep solar minimum that lasted from 2007 to 2009. In fact, in 2008 and 2009, there were almost no sunspots, a very unusual situation during a solar minimum phase that had not happened for almost a century.

Consequences of a weak solar cycle
First, the weak solar cycle has resulted in rather benign “space weather” in recent times with generally weaker-than-normal geomagnetic storms. By all Earth-based measures of geomagnetic and geoeffective solar activity, this cycle has been extremely quiet. However, there is some evidence that most large events such as strong solar flares and significant geomagnetic storms tend to occur in the declining phase of the solar cycle. In other words, there is still a chance for significant solar activity in the months and years ahead.

Second, it is pretty well understood that solar activity has a direct impact on temperatures at very high altitudes in a part of the Earth’s atmosphere called the thermosphere. This is the biggest layer of the Earth’s atmosphere which lies directly above the mesosphere and below the exosphere. Thermospheric temperatures increase with altitude due to absorption of highly energetic solar radiation and are highly dependent on solar activity.

Finally, if history is a guide, it is safe to say that weak solar activity for a prolonged period of time can have a negative impact on global temperatures in the troposphere which is the bottom-most layer of Earth’s atmosphere - and where we all live. There have been two notable historical periods with decades-long episodes of low solar activity. The first period is known as the “Maunder Minimum”, named after the solar astronomer Edward Maunder, and it lasted from around 1645 to 1715. The second one is referred to as the “Dalton Minimum”, named for the English meteorologist John Dalton, and it lasted from about 1790 to 1830. Both of these historical periods coincided with below-normal global temperatures in an era now referred to by many as the “Little Ice Age”. In addition, research studies in just the past couple of decades have found a complicated relationship between solar activity, cosmic rays, and clouds on Earth. This research suggests that in times of low solar activity where solar winds are typically weak; more cosmic rays reach the Earth’s atmosphere which, in turn, has been found to lead to an increase in certain types of clouds that can act to cool the Earth.

Outlook
The increasingly likely outcome for an historically weak solar cycle continues the recent downward trend in sunspot cycle strength that began over twenty years ago during solar cycle 22. If this trend continues for the next couple of cycles, then there would likely be more talk of another “grand minimum” for the sun. Some solar scientists are already predicting that the next solar cycle, #25, will be even weaker than this current one. However, it is just too early for high confidence in these predictions since some solar scientists believe that the best predictor of future solar cycle strength involves activity at the sun’s poles during a solar minimum and the next solar minimum is still likely several years away.

Equipment / Re: WWV receiver for ntpd time source
« on: July 17, 2014, 0125 UTC »
WWVB would have to be handled differently. ntpd's WWV/H support is via audio and its specific format. WWVB is just different enough to not do it as is. I'd like to have WWVB as well, but that one will wait until WWV is going and after the data is collecting for the WWV ionosphere measurements.

However, someone from 2003 thinks it wouldn't be that hard:
http://lists.ntp.org/pipermail/questions/2003-November/001357.html

Quote
"The signal is now very similar to the WWV/H demodulator/decoder and
 the same algorithms can be used. All you would have to do is change the
 seconds state machine table."

"Here's a way to test the idea without building anything. Several
shortwave receivers today can tune 60 kHz with 1-Hz resolution. Wind an
antenna on a ferrite rode maybe with a preamp. Radios I know about have
atrocious low gain at and below the broadcast band. Set the BFO to
produce 100-Hz note and connect your soundcard. Rip off the WWV/H
driver, toss out the 1000-Hz stuff and synchronize directly to the
subcarrier. Weekend project."

Maybe, maybe not. Perhaps some day I'll look at the WWV/H audio source code in ntpd and see how easy it would be to alter it. Any serious mods would probably beyond what I can do.

One of the problems today with WWVB is that there used to be a little receiver called the CMMR-6 that apparently worked fine. However, its been long since discontinued.

Perhaps getting a WWVB radio that supports IRIG audio. But I have a feeling that means $$$.

For even more fun, ntpd also supports demodulating CHU without any more fuss than WWV/H.

Wonder if there's a way to integrate an SDR into the mix so it can listen on multiple freqs at a time, say, 60 kHz, 2.5, 3.33, 5, 7.85, 10, 15, 20, and 25 MHz. It would monitor all of the time freqs and sync to any that are good enough, meanwhile keeping track of signal strength & demodulation quality. Each freq would be its own time source in ntpd. So if all were sync'd, would have 9 sources.

Obviously need custom code to take care of that and something special in ntpd. This just made a long-term project list. Good thing I bought a DSP programming book last year. Will probably start with an SDR monitoring one freq at a time and when it becomes too poor to sync, then it scans for others.


I've had a few clocks around here for many years that sync to WWVB. Three, I think is the current active count (although I thought there was more). Clock radio, mantle clock, and a wristwatch. Wish my SW receivers with the built-in clocks could sync to WWVB, WWV/H, or CHU.

Equipment / WWV receiver for ntpd time source
« on: July 16, 2014, 0104 UTC »
I've been busy with ntpd as of late and decided that I need to have my own stratum 1 servers that sync to WWV (5, 10, and 15 MHz, optionally 2.5, 20, and 25 MHz).

Have two paths:

In one case, have one computer hooked to a receiver on 5 MHz and another computer connected to a receiver on 15MHz.  Both would run ntpd that can decode the audio output. Their success would come & go throughout the day, but they would be complimentary and any client stations would get at least one of them.

Alternatively, have a one computer and one computer controlled receiver that would be commanded to switch freqs depending on the time of day.


Then got to reading about other stratum 1 servers that use GPS, GNSS, and CDMA. Saw an article that I found that had a fascinating tidbit in it:
http://www.hfindustry.com/meetings_presentations/presentation_materials/2009_feb_hfia/Presentations/ShadNygren_HFIA2009.pdf

Specifically, from page 3 of the document:
• Use difference from local CDMA 1PPS UTC to calculate path length from WWV to Datron
• Use path length and great circle distance to calculate Ionosphere Virtual Height

The document it references from 2008:
http://www.hfindustry.com/meetings_presentations/presentation_materials/2008_feb_hfia/presentations/08_shad_nygren_hfia_presentation_feb2008.pdf


Right now, going to start with the stratum 1 server(s), then eventually run that experiment as I get more information about it.

Any recommendations on a WWV radio? I have a Yaesu FT-840 that I'll probably use in the near-term to get the thing going, but don't want to tie that radio up for too long.
