Posted on 04/09/2013 6:18:35 PM PDT by matt1234
Within hours of South Korean news sources breaking a story that several Sang-Ho class submarines had disappeared from their North Korean bases, a ham radio operator named Tim, picked up a numbers station broadcasting on the same frequency as The Voice of Korea propaganda station. What makes this even more interesting is that at the tail end of the numbers transmission there was a long duration digital transmission as well.
So why is this important and alarming?
There are several reasons why this new development is particularly alarming. The first being the existence of the numbers station coming online shortly after the submarines put to sea, but more importantly is the digital transmission apparently tacked onto the end of the transmission and the ramifications of that transmission.
Throughout the Cold War numbers stations were used to convey encrypted messages to covert operatives. The station would come online broadcast a series of numbers, possibly multiple times, then disappear into the darkness. Those numbers were used as coded messages to be decrypted on the other end by the in country operative. Examples of these numbers stations can be found at The Conet Project Archives. So what makes this number station significant is the proximity in timing to the disappearance of the San-Ho class submarines, as well as the digital transmission. It is important to point out that the Sang-Ho submarines in question were effectively purpose built for covert insertion of small teams ofNorth Korean Maritime Commandos who are part of North Koreas much lauded Special Operations Force. So at this moment there is a covert North Korean force apparently heading for South Korea.
The Sang-Ho submarines can carry as many as 30 commandos per submarines giving the current submarines a combined force of around 60 troops. Those 60 troops are specially trained to carry out behind enemy lines covert actions such as sabotage and assassinations. So in this case the numbers station was most likely broadcasting a special code to North Korean operatives to announce the impending arrival of the covert operations teams.
The Digital Transmission
What is more significant is the digital signal at the end of the transmission. Digital transmissions such as this one may indicate the presence of a burst transmission which contains a compressed and encrypted message bound for some covert force, somewhere. Typically a burst transmission is used to minimize the download time at the end point to prevent discovery. The unusual part of this potential burst transmission is being attached to a numbers station as well as the length and the power of the broadcast. Normal burst transmissions are in the one second to two second range. This transmission was in the 10 to 15 second range which is almost unheard of, unless the end point is a submarine.
The ham operator who picked up this particular transmission was located in the Midwest of the United States, and he reported the transmission was received 4 by 5 indicating a significant power was used to send the transmission. That level of power coupled with the length and possible submarine end point opens up a new and alarming tangent to this escalating conflict. It is important to point out that the numbers are being read in Spanish but that is typically done to confuse the original source of the transmission. In this case the transmission was detected on a upper side band of the AM range used by the Voice of Korea so while the numbers are Spanish the transmission does appear to originate in North Korea. That fact coupled with the missing submarines seems to provide evidence of the nature of the transmission despite being in Spanish. Its also important to note that the numbers being in Spanish could also be used to employ a different set of codes in the operatives code books.
Now the really alarming part, if the submarines and number station wasnt alarming enough. One of the things that hasnt been discussed in mainstream news is the fact that North Korea has between 22 to 24 diesel electric submarines of the Romeo Class. These subs, which are heavily antiquated and for the most part decommissioned, are capable of open ocean missions. They have also been successfully retrofitted to carry a small anti-ship cruise missile, actually six of those missiles and while the YJ-8, the missile used for those retrofits, is an anti-ship missile (similar to the Exocet in use) they could carry a conventional warhead used to hit a building, damage a runway or some other kind of ground based target. But its not beyond the pale to suggest that the warhead could be modified to carry a more interesting payload and it is important to remember that North Korea does have one of the largest chemical weapons stockpiles in the world. The submarine in question also has a range of over 9,000 miles but a top speed of 8 knots which is fairly slow. Its also a diesel so the submarine would would have to run on the surface to recharge batteries of let off exhaust from its engines which is a byproduct of their origin which was late war German U-Boats. Its also important to note that Romeo Class submarines which have been retrofitted must fire their missiles from the surface.
We dont currently know if any of the Romeo Class submarines are missing, and if they are where they are going or even if they have been retrofitted but if they have then they represent a significant risk to Japan, Guam and even the western coast of the United States. As I said its impossible to know if that is the game plan but experts I consulted seem to believe that a burst of that size and power would be destined for a submarine be it Sang-Ho or Romeo Class.
All things being equal the transmission could have also been destined for the commando forces aboard the Sang-Ho submarines, which we know from news reports are at sea, or targeted for the operatives that will be meeting the covert operations teams on their arrival.
At this point we only have the transmission to go on, but its ramifications are both interesting and alarming at the same time. The transmission and the missing submarines also indicate a significant escalation in the deteriorating Korean political situation. Given the deadline North Korea has issued for embassies to shutdown and their staffs to depart we will soon find out.
Tune into Ground Zero Radio Tuesday 4.9.13 Clyde Lewis will be doing a special show on Numbers Stations and we will be discussing this evolving story.
Thanks again to Tim for finding this broadcast and bringing it to our attention, and as with all things like this please do your own research and come to your own conclusions. What I have provided here is just a few of the possible scenarios gleaned from research and the news of the day but it is by no means the only option. The information presented is fairly easy to find with some good keyword searching on your favorite search engine as well as the Wikipedia and FAS.org. So trust no one and make your own final decisions.
An insane nation with WWII submarines and WWII tanks...
And we let them develop nukes.
Tomorrow is NK Commie D-Day... check that. It is already the 10th of April on that side of the world.
Its more likely NK doing this.
Spooky. What are they up to?
Loose lips sink ships.. If it’s NK transmission, no worries. Team 0bama is all over it. /s
continuous transmission by numbers stations are likely following the old Soviet example of continuous transmission along the fire chain of missile bases, that way you never know when they are going on alert like you would if everything was always quiet then all of a sudden message traffic starts up and down the fire chain telling you something is up
4 8 15 16 23 42.
Your input would be appreciated.
Power went out earlier. Thought maybe Kim had slipped one through.
Not exactly. It says the transmission was on a frequencey normally used by the NORKs. That doesn't necessarily mean the transmission originated in N. Korea. (Shortwave transmitters commonly step on each others' frequencies when they are hostile to one another.) I do not believe a single, amatuer HAM/shortwave receiver could determine the originating location.
Kim has a rong mustache.
‘Your input would be appreciated.’
My team of crypto-experts have been pouring over the codes and this is what we have so far...
D R I N K Y O U R O V A _ _ _ _ _
So far, that is all we have been able to determine. Hopefully, the coming hours will include the breaking of the complete code.
And the phone rings at 3:00 am...
I wonder how those libs in California are feeling about now.
im so rooney, so very rooney.....
I have not notice anything out of the ordinary, but not that active lately. Family member health issues have my time filled.
Praying for you and your family
25 or 6 2 4
I saw an event several years ago where a bogus distress sig was sent by a man in FL trying to convince others he was in distress at sea. After the fact, someone regurgitated the RF spectrum in 3-D (triangulation) and determined his location. Shut him down. There are strange things that do not appear possible that are.
In what state are you? Ours went out, too. (I thought the same thing about the UN-one.)
Obama partying on the eve of the threat.
“Tomorrow is NK Commie D-Day... check that. It is already the 10th of April on that side of the world.”
There’s that 9 number again that Chia Boy is obsessed with.
4/10/13 = 4+1+1+3 = 9
Their satellite passes over the US twice tomorrow night.
Thank you very much for your prayers. They help and are appreciated here.
It is psychological warfare, nothing more. The reason being is that voice transmissions (even ssb) on commericial frequencies is just saying “here I am, look at me”, and is incredibly inefficient for all but the most basic communication. There exist a myriad of off-the-shelf technologies that would be orders of magnitude more secure, resistant to detection and/or decryption, and of higher data throughput. Slow narrow-band mfsk or differential psk (like good old psk31) using hard encryption and turbo code forward error correction, frequency hopping and orthogonal coded spread spectrum using low power to keep it below the noise floor, packet bursts on psuedorandom agreed frequencies, the list goes on. Reading numbers on the air is like those “spy cameras” from the cold war that look clumsy and dorky by today’s standards. And there are better frequencies, like VLF for subs, and the mid-HF range for reliable NVIS (near vertical incident skywave) point-to-point communication. It’s all bluster and psyops.
No problem, we can all sit it out in the public bomb shelters our government has made for us like the Russians have for their citizens.
“The ham operator who picked up this particular transmission was located in the Midwest of the United States, and he reported the transmission was received 4 by 5 indicating a significant power was used to send the transmission.”
The so called dead N Korean satellite is coming up over the midwest tonight.
I have no radio equipment here, but finding a signal on just high frequency alone would be looking for a needle in a hay stack.
It would also be encrypted and certainly not in English.
Well, we can revisit that contrail/missilelaunch off the California coast again, but hey,
what difference would it make ?
Here, too. SW WI. We are having a storm, w/tornadoes to our West and North. Went out for a few seconds, came back on and went out again, then back on and is ok, now.
Clear for now. Over LV in about an hour.
That is why I suspected the transmission was not directed to subs. Why would they transmit to subs on a SW freq?
However, I can still imagine agents receiving instructions via numeric codes on SW freqs. I have a copy of Passport to Worldband Radio 2009 that shows how N. Korean agents receive instructions this way. Also, I have heard numeric codes in plain voice (Spanish) on SW freqs before.
Of course the actual, intended recipient is speculation on my part.
That was back in January.
May not be what Rand Paul is saying now.
I find Geraldo to be grating no matter what he says.
Nuke unloaded in Mexico, and is loaded on a plane.
The plane flies to the middle of the country, setting off an EMP.
To get serious EMP effects, you have to detonate above 150 miles. No airplane can do that.
Well you just bring it to the Washington coast, dude. You won’t be there long.
My neighbors fifty years ago built a bomb shelter back in the Cuban missile crisis days. Wonder if it’s still standing.
