Strange 30 meter Signals

[K3CW]

On 24 April 2002 at around 500 UTC I copied a number of strange signals on and around 10.119 MHz. #Streams of nonsensical letters were coming in at 20 over 9 here in Philadelphia, PA. #For example, I copied "TDGGN DUMDA RURRD" being sent repeatedly as well as longer non-repeating sequences such as: "RIMDRITWURGUAUURNAWNTTWUR..."

There seemed to be several signals very close in frequency, transmitting simultaneously, so at times it could be difficult to copy. #Does anyone have a clue what these might have been??

Ok I don't have a hf radio but i do have shortwave radio, and i hear them too. I discoverd some near the 8 megahertz band too, but these do sound like beacon's and I have read some stuff about them, that they may be numbers stations. These are stations that send codes to their agent's, and the station transmiting may be a inteligence agency. Well that's what I heard. http://www.qrz.com/iB_html/non-cgi/emoticons/confused.gif

Maybe its Martian for "lets conquer the Earthlings". http://www.qrz.com/iB_html/non-cgi/emoticons/tounge.gif

Seriously if two or more stations were on the same frequency you may have been running them together. This would fill blank spaces and add dits or dahs into other letters.

On the other hand I may not have a clue what I'm talking about. Good luck figuring it out. http://www.qrz.com/iB_html/non-cgi/emoticons/wink.gif

What you are hearing is an encrypted message. #The five letter groups are common to various encryption methods. #The other signal may be a jammer. #Also, there is a method of weather information that is similarily encoded. #I've heard this station many times, and they seem to run high power, or they're near my QTH.

I'm not sure anymore, but once upon a time, the 30m ham band was shared with other users, and we did not have the primary allocation. I know the US Navy used to have a TTY transmitter on about 10.119 or 120 . . . I'd say the allocation is probably still secondary, and the five letter groups (standard way of transmitting data on CW) are military.

Just my $.02 . . .

May be, but I am a Navy MARS member and once again today it came up at a MARS meeting that our military is no longer using CW, so military use is unlikely. #I wonder if this should be reported to Homeland Security officials?

If I were you and were hereing the signals on A regular basis I'd report them to Homeland Security! I would be happy to do so myself but I currently do not own An HF rig. With what has happened on September 11th we cannot take things for granted anymore! Glenn KO4VP

I can't remember where I heard this but I remember being told that AL-Qaida and other terrorists were using ham radio as communications but I am not sure if that is what this is? Could it also be possible that someone accidently started praciticing to send code and didn't unplug the keyer?

[w6th]

These are 5 lettered coded group words and will be deciphered by a machine. I have copied for many years these code groups when in the military. #I was a fixed station radio operator in the U.S. Army Signal Corps and am quite familiar both fixed station and in the combat areas. All military countries use these #or this type for secret messages.

[w4mqc]

I was just working a little 30m and below the band on 10.045.5 Mhz is a station sending letter groups...
This one might very well be weather related...
he is sending "vvv de 4xz 4xz , , " several times then a report of some type but encryted. Anybody recognize the callsign of 4xz?

You guys should all realize that the NSA is in all likelihood 'way ahead of all of you on this matter. Intercepting and decoding this kind of thing is what NSA at Ft. Meade and other locations does for a living.

on april 15-16 @ 0530 utc i copied a similar CW signal with 3 operators @ 3.700 mhz using 4-5 letter and number#groups and was very slow and sloppy @ abt 2 to 5 WPM with no legal callsign they ID themselves with ze2eee eeeie eeeh rskeeeie broeeeh

I have only been a HAM for about a year and do not have my HF privileges yet but I have been a SW listener for years. What you are hearing is probably one of the many "Numbers Stations". #There are many theories as to what it all means. #There was even a case recently where a spy was caught in the US with a SW radio and a laptop with a decoding program on it. #This person was discovered to have been getting messages from Cuba in the form of numbers series. #Here is a link that explains "numbers stations" better than I can.

these sigs have been on 30 meters on and off, usually during the early morning hours
for the past several years. Not only are they very strong here but also very very wide.
I always took them to be practice transmissions from the military or some other
group.I doubt what your hearing would be terrorist related at all. The sigs that made me
suspicious were the ones coming from headings around 60 deg true that were just
random carriers with various on and off times and jumping slightly maybe a few hertz.
these appeared about 6 weeks before the happenings and were on the lower portion
of 40m. As mentioned around if you hear something suspicious tape record it and contact
the proper people either the fcc,fbi or even w1aw and forward info to them.

[wa4fki]

I never heard the unknown CW stations sending 5 letter coded groups on 30 meters but I did hear on 15 meters in the CW portion of the band sending 5 letter coded groups this week. The entire band was dead, no signals were heard on phone or SSB except this weak station sending coded traffic. I listened for a while and finally the station was lost in the noise.

Many years ago my job in the military was to copy stations like this for intelligence purposes.

WA4FKI

[w3sy]

Hey, I've heard some other mysterious transmissions as well! And I've heard 'em on all the ham bands...

What's KWA KWA KWA mean? How about NNGT NNGT NNGT? And how come after those signals are sent, the station sends TEEE before sending their call sign??


And where is ZAZ, FL???

I've heard these mysterious signals for almost 32 years!

(snicker)

p.s. Seriously, "4XZ" is a commercial station in Israel. You can get that info by looking at an international callsign chart.

Is it "they" or "them"? http://www.qrz.com/iB_html/non-cgi/emoticons/wink.gif

There is a most common mode to operate army HF station first send VVV (group of letters V to tune transmiter and occupied a frequncy) after than key DE and call sign such x1wy or y9sa , once before when i use special call sign yu0j one of this army radio operators ansver me but said wait after checking(because i am not on army list) he continue with cq cq cq de y9sa .On the same frequency that i first call cq de yu0j . Interested thing that he use a Ham radio frequency 7.041 MHz .
Anybody remembers a "woodworker" jammer on 20 meters, typing dot's and slide thru the band up and down?

[w9gb]

These signals have been on or near the amateur bands for as long as I have been listening (1972). #They are most likely military and/or intelligence signals.

They are 5 lettered coded group words that are deciphered by a computer (or a human operator).

I remember the commercial radiotelegraph endorsement test given by the FCC (1970's) was at 18 wpm as 5-letter group "words". #Passing this test would also give you code credit for the amateur extra exam.

The ARRL code practice still performs this method at various speeds at the end of code practice.

Just because a skill is no longer "required", does not mean that it is no longer used. #In fact, it may be highly prized within the intelligence community (like some Asian / Arabic languages and dialects). #

Just last year, a major defense contractor and consulting firm had an employment ad requesting specific computer AND sending/receiving CW/Morse Code skills (13 - 18 wpm). #This contractor's position was based in Langley, VA

w9gb

[w8ob]

Yes the commercial radiotelegraph op cw test for the 2nd class was 5 letter groups at
16 wpm and plain text at 20wpm. the first class was 5 letter groups at 20 wpm and plain
text at 25 wpm. Just a suggestion to you guys posting portions of what your receiving
off the air, I think for security reasons I would not add any groups you are receiving on
your posts.....never know!. Anyway who sez CW is dead?

[kg4ray]

I just decoded the message as posted using the UberDecode Mega Ultra Plus. The message is as follows:

USA de Canada: May I barrow a cup of surgar?
Canada de USA: Yes, here is one cup.

I hope that clears things up.

[N1RR]

Copy these 5-letter groups (Can also be 5-digit groups)
and forward this along with the following information:
Date, Time, Freq, Direction,Signal Strength and quality
to:

U.S. Secret Service ( In most major cities.)
-OR-
F.B.I.

Do not worry, all these transmiting , NSA regulary monitoring and try to broke codes.
Do you know that is possible to by for little money AM receiver who have normal FM band and 3-5 HF bands, this is product for some people who living from espionage. More than 90% these content on AM modulated CW or phone AM is whitout any meaning but this transmiters still transmit those to fill up time. And users know what part of 5 sequence letters or numbers is real code.
Problem is when this transmition work on Ham radio frequency. This is abuse but how detect and finding source (NSA have a equipment even orbital satelites).? Ham radio operators cannot found, or source is so far(out of country). But in case when source is definitive is in same country and location is found withouth errors, only authorithy can do it some thing.

How about who ever hears these emission's get their rigs tuned, and see what direction these signals are coming from. That way we can at least have some sort of an idea as to what part of the world they're coming out of.

[NE5U]

Howdy,

I was tuning through 30m as I was drivng home from a job on the evening of the 24th and I also heard the 5 character strings. A couple of things come to mind. They were sent at 18 WPM. The letters were sent by someone with a very good fist or a machine. Likely it was the latter. I copied about 5 - 10 words and got bored. Gibberish is more difficult to copy since you can't anticipate the next letter. Though I can't give you an S meter reading I do not remember that the signal was particlularly strong. The letters were always clear though. Even with the DSP on and set "tight". Come to think of it, the reason the DSP was turned on was due to some interferance from a station adjacent to the "code practice session" (That's what I thought it was).

On another note, Quite often I have tuned and copied a station, very near 7100 kHz (just a little below actually), that sends scripture via CW. It's, again, very well sent and likely coming from a machine or computer.

[W5HTW]

Military. But not always US military. From about 10 MHZ up well past 12 MHZ is military and marine. I spent some time copying a CW tape at 18 GPM that sent a number of 5-letter messages. It was a rebroadcast, with messages for different addressees all in sequence.

It is a fallacy that military does not use CW. Perhaps our military has given up on it, but some others have not, and that includes friendly nations like Mexico, as well as unfriendlies like Cuba. In addition, in this 10 MHZ range, you'll find many US stations on various digital modes, including encrypted RTTY.

It is indeed a shared band, and these guys have the right to be there. NSA knows about them, rest assured, and you need not report them to anyone anywhere. Just ignore them, and QSY. Or use them for code practice.

Incidentally, I disagree with a statement made by someone about code groups being harder to copy because you can't anticipate the next letter. It is this anticipation that slows us down, as we try to "read" or "guess" what is being said. Actually, 5-letter code groups are, for a given speed, much easier to copy than clear text, as the mind no longer tries to "read" the content. Try code groups (equal length - 5 letter) at the same speed as clear text and I think you'll find the code groups are more fun. I spent a lot of time copying code groups, after going through a school teaching them. But then, some people learn differently, so it is certainly possible for some that clear text is easier. I believe, though, that isn't really copying so much as guessing. And when you guess wrong, a lot of time is wasted correcting the error, while another ten letters go by. That, at least, has been my experience. But whatever pokes your potatoes. Doing code any way is more fun than pushing a PTT switch!

Sorry but I disagree. I think if you see (hear) something and feel that it might not be right...report it ... don't ignore it. After all our guys are paid by us to check this stuff out. If they get to many reports They can tell us to ignore it.

To many things go by that shouldn't because people ignore it.

Ya i agree they might have already checked them out.
Without saying something YOUR not sure.

If they get a little hot under the collar because to many report on the same thing they should look for other work.

I have heard there are some that knew what those jokers were doing in Afghanistan. They tried to do the World Trade Center in once…. And came back almost 10 years later.... and finished the job...... Don't ignore anything better to report and be told that it has been checked out rather than have something happen.. Life is to precious!!!!

http://www.qrz.com/iB_html/non-cgi/emoticons/confused.gif

The Federal Government has already sent out a request for Amateur Radio Operators to monitor the airwaves and report anything suspicious. I have not heard them make any statements about ignoring anything……

A little story from the past:

In the mid-80's, I was on a Korean crew barge, moored to an Indian offshore platform about 200 miles off the coast of Bombay in the Arabian Sea. I was up in the radio room waiting to make me weekly satellite phone call (Intelstat, I think) to talk to my wife. (That was way before email and Iridium) While waiting, the radio operator was sending CW with his bug on a huge JRC transmitter so I thougt I might as well copy it to pass the time (it was a long wait) .

All I could copy was jibberish. After copying about a page of this, he stopped transmitting and I went up to him and showed him my paper. I introduced myself and showed him what I had copied and told him that this is what he sent. He said "no way!" (in a very heavy Korean accent). I then told him that I was a ham operator and knew the morse code. He still insisted that he did not send what I wrote down. I had to show him that I could send CW with his bug and he sent some back to me that I could copy perfectly. That is when it dawned on both of us...he was sending Korean morse code!

Allen, N5XZ (WB5BIR back then)

[N0PV]

What you are hearing are most likely EAMs or Emergency Action Message sent by US Military Centers such as Andrews AFB and Offutt AFB. #Many times they will broadcast simultaniously so that all stations receive the message. #Most of the time you will also hear reverb on the signal this is to assist in pacing the operator on spacing of the letter (this is on voice).

The first group you heard is the preamble to the message usually is sent several times and this is a string of 5 character groups. #Then the standard message follows usually 26 characters sometimes they vary.

If you want to hear more of the same time of messages tune into 11.175 USB to listen to the AMC (Air Mobility Command) USHF radio stations making phone patches for military aircraft and sending these types of encoded messages.

As a side note them more important ones are preceeded with the prosign SKYKING and usually are timely important orders and information. #

MAINSAIL is the prosign used as #CQ on this frequency.

Embassies also use this type of messaging system.

Yes i know, and because these transmision i say if you 100% shure to origin signal (for example foreign embassy) it is also ilegall, but connect authority, local police cannot visit foreign embassy(this is against the international law). But diplomacy will send the official note to country from wich embassy ilegal transmision belong. Now embassy use satelite link(cannot track this conversation from the ground)

AHHHHH! #These stations have been on the air since about 1912 in one form or another. #These are coded messages used by everyone from the military organizations, spies, drug runners, or anyone that wants to keep a message a secret. #Some of the more famous are "Numbers" stations. #With these stations the "operator" is a pseudo mechanical female voice (usually in Spanish) that send out a series of numbers. #While more rare, there are male stations as well as Morse Code. #Other stations use letters; and others alphanumeric. #HF is used as the message can be received on equipment available in almost every part of the world. #It would not be unusual for someone to have a short wave receiver. #Would it be unusal for someone living abroad (a US citizen for example) to have a radio to listen to home shows (VOA)? #Plus these signals travel world wide; making it difficult to figure out just who the message is for. #

During WWII both sides used machines to do the sending. #Encryption was accomplished by rotating discs that moved as the operator typed on a keyboard. #The receiver would know the wheel and sequence being used and would decrypt the message. #Code breakers in the US broke both Japan's and Germany's codes. #The only code not broken was the US code that #used Native American languages as their encryption scheme.

I would have to hear the signal. #What frequency and what times? #As for reporting it to Homeland Security, I guarantee you that NSA has already listened to it and logged it if it is a NON-US territory transmission. #Each listening station has at least 400 or more operators a shift sweeping the frequencies for intelligence. 24 hours a day, 7 days a week including holidays. #There isn't a dit, dah, plink, or plunk #that isn't copied, logged and identified. #That signal could really be anything and hearing it would help in IDing it. ##Please indicate frequency and times of transmissions. #Thanks. #Also, I doubt terrorists would bother using morse either. #Too easily intercepted and fixed to position. #Peace and Goodwill.

and you mean that these encrypted message broke??? do you know how many letters i use before encryption?? only for letter and try these encrypted message split by the group of five and transmit like CW, can you open message???
No of course because this is strong encrypted message. But answer is so easy.Imagine that message go only 15 minutes at day other group of five is computer random generated letters to fill up the time.(transmitting 24 hour at day 365 day at year) You even do not know which part of transmission is encrypted message.

Well you can add Friday to your list of transmissions from the mystery station. I just heard a station sending 5 letter coded groups at 07:28 local time. (am in NC)

Signal strength was S9+30db. CW was not hand sent I dont think, was sent automaticlly with a keyer of computer keying transmitter, perfect keying and perfect spacing. When the station was finished sent AR three times and VA three times. Station signed off at 07:38 local time.

Good monitioring.... 73's ya'll from WA4FKI http://www.qrz.com/iB_html/non-cgi/emoticons/wow.gif

Numbers station...check Monitoring Times. I still think that numbers stations give a good code practice session for a "neo-novice". Only problem is, there's no way to verify your score..W1AW, on the other hand, has a perfectly viable means of verification, if you are a member and a subscriber.

10 mhz is still the best band of all. It's the only HF band that is virtually open 24-7 these days, and when the solar cycle wanes, it is a haven for vagabond DXer's with a brass itch to scratch. Too bad, that the ARRL chose to expunge the WARC bands from the DXCC and it's probably the most under-utilized band today because of that "bureaucratic snub"...



(I used 10.100 mhz to listen to Shoemaker-Levy 9, "G" impact, July 18, 1994. I was using my TS-440 and a G5RV @ 35 feet, AEA facsimile software at 120 LPM on an old 386 computer and right around 9:30 PM, I saw the waveform. I had read in QST a few months before that it was possible to record the radio pulse from the impact and, sure enough, I saw it rise and fall on my monitor. Only problem was, I forgot to save it to file... Scientific American carried a similar graph of the pulse in their September issue. It was the strongest, wideband signal ever transmitted naturally from our solar system since homo sapiens evolved the ability to receive it. I am privileged to be among their company.)

Living overseas for 7 years I quite often came upon the same thing. I was told by various folks that these are 5 letter code groups for goevrnment activities ie: spying. Just one possible answer to the many I see here.

I don't have any idea what the quote is about, unless he is talking about SELCAL. Every airline and military #aircraft flying over the oceans uses SELCAL, and the tones are modified for each flight/aircraft number, so for a particular airplane will be different for each flight number it uses. #This is simply an alerting call tone used to alert the aircraft for broadcast of changes in weather, or other conditions that may affect the flight. #SELCAL is for SELECTIVE CALLING, and it uses a pair of tones, followed by a second pair of tones, in a two-step tone encoding procedure, to trigger an alarm in the aircraft. #That alarm just tells the aircraft that someone is trying to reach them. #Sorta like the phone ringing!! #It isn't secret, and has been in use for probably forty years. #

N0PV -- EAMS are voice messages, not CW. #

Someone said "they only use ten letters." #That should have suggested something.

This station on 10.126 is probably Cuban in origin,and uses the standard Cuban cut number format. #Ther are other cut number formats but this one seems to be mostly used in Latin America. # A similar station can be heard from time to time on 3926 KHZ, and signal strength would indicate it is possibly in Central America or Mexico. # Still, it could be Cuban, but it comes into the US Southwest with great signal strength, and almost no QSB until late in the evening, indicating a path of perhaps 700 miles. #(With summer, that is changing.) #The majority of the "numbers" stations, contrary to popular belief, do not use major multi-kilowatt power levels. Typically they range from 1 KW to 5 KW, but they use excellent antennas, and they make use of the best info in propagation.

Note, 3800-4000 KHZ is not a worldwide ham band, so finding military, commercial, broadcast stations in that range is not unlikely and isn't illegal. #Like the 10 mhz band. #It is shared. # On 75 meters, though, I believe hams have priority in Region II, but each country is allowed to decide what it chooses to let hams use. #

Most of these signals have been on the bands for years. #They are not new to NSA or other 3-letter organizations. #

Ed, when an aircraft is built and the HF system checked out, the Selcal address is assigned by Arinc. That code (4 digit) is for the life of that aircraft tail number or operator. If the aircraft is sold, then a new Selcal number is assigned, because the old owner usually replaces the aircraft, and desires to keep their old Selcal codes.

10Mhz has a number of Arinc stations..

Arinc .. Aeronatucal Radio Incorp. They are the group who usually sets the specifications for lots of data bus formats...ie Arinc 429, Arinc 1553 (military), and so on.

Lots of good info Ed..!

W0LPQ - BILL

Thanks for the additional info!

Was just speaking from my own experience. I was in theexception - where things DO change, including radios. AND tail numbers. A small part of my job was to do exactly that. (Someone else did the tail numbers - I did the electronics.)

I first met up with ARINC in the 50s, when I was in high school, at Stapleton, as part of a class in high school called (My God, the dinosaurs are back!http://www.qrz.com/iB_html/non-cgi/emoticons/wink.gif Air Age Education!! Yeah, really. To a young ham, aschool-sponsored visit to the GCA systems at Stapleton, and to see a demo of the ARINC link, where a friendly operator hit the foot treadle and talked, on VHF, to an aircraft in California, was amazing. He explained the link, now as common in the ham world as praire dogs on the highway. We were even allowed into the GCA room, and saw on the radar two "modern" F86s approach Lowry - and just as the radar said they were overhead, we heard them. Took us to the simulator, I think it was a DC7 model for UAL, but we didn't get to use it - just see it and how it worked. I was 17. Neat stuff. (And easy class for a credit, too!http://www.qrz.com/iB_html/non-cgi/emoticons/wink.gif Led me to a career in electronics/communications.

Met up with SELCAL in the early sixties, first in point to point HF, and then in our own brand of aviation. Later learned it was used in fire deparements around the nation, to page out volunteer fire fighters, though that is a two-tone system, not a four tone. These days I hear 2-tone SELCAL every day as the local county dispatch calls up EMS or VFD vehicles/crews.

On HF, we used an auto-responder SELCAL system. It was certainly new to me. Muy interesante.

73, and thanks again

While operating in the dark one night I went to change bands and accidently ended up on 8.572.45 Mhz. #Well I started receiving CW. #I got the pen going and I could copy CQ CQ CQ de CLA CLA QSX 8368/12552/16736 #CQ CQ CQ de CLA notice to Mariners CU ian revolutionary navy...a bunch more stuff that was too much for me to copy. #Sounded like some coordinates or something and some dates and times. #Admittedly it was some pretty gud code practice for me, since im a slow-coder. #It's obviously some other lifeform from another planter trying to make contact with us. #But, since it was out of band I couldn't answer them.

[k7unz]

Relax a bit my friend, what you're hearing has been on the band long before we were allowed operation there. I do wish more US hams realized that the 30 meter band IS NOT a "ham" band. We are allowed use on a "shared secondary" basis, which means just about everything in the world has priority entitlement to the band over us. What really burns me is hearing some idiot US hams trying to block these stations, telling them to get off the band, and just plain causing interference to other users of the band. You are just showing the world your stupidity and lack of knowledge of your own allocation. As for the 5-character groups you hear transmitted, this is the standard way "off-line" encrypted messages are sent. What you hear is the encrypted message. The receiving station will then decipher it with another piece of equipment, using the same code settings the sender used to encrypt the message. Being HF, and subject to mother nature's whims, what may be a local transmission in Asia, becomes solid copy in the USA, and vice-versa. As the military (ours or anyone else's), and any undercover agency, have no wish to reveal who/where the sending station is located, the "call signs" you may hear have no meaning in reality. And please do understand that you can not apply what you accept as "your band" on the rest of the world. Fact is, radio spectrum is a national asset, and nations (including ours) will use it as they see fit, when they see fit, and "your" allocation means nothing anywhere else in the world. Report it to someone if it makes you feel better, but try to remember, the FCC can't even contain the CB population within it's allocation......and they created that monster! I tell you this from 30 years experience in secure military communications. And oh yes, do try to remember that when you make public portions of communications you have overheard, you are actually in violation of FCC regulations yourself. So I suggest you refrain from posting actual excerpts on these pages. The best we can all do is grin and bear it. Interestingly, I've just been re-reading some old ('58-'74) issues of QST. Would you believe that exactly the same thing was going on back then?? 73, K7UNZ

I'm currently at a conference with the SETI folks. If you want me to forward this to them I will.

[n1nkc]

when i was stationed in japan 20 years working in military intelligence.. the chinese military were using
cut numbers also... and the characters "ar" was end of message and "va" is another way of sending
"sk" ... -.-

Hey, think about it. Some of first manmade radio transmissions was in C.W. If a civilization heard the transmission, would'nt they try to send in the same format or mode?

Maybe all this "SETI" stuff is a waste of money. The first contact will be by a..er..a Heathkit HW-16 and a dipole!

Stands to reason that if it took 40 light years to reach them, they are sending back!

A "Novice" class license on a distant star. Some alien kid with his homebrew transmitter!!!

Maybe the message is "your signal is chirpy."

There has been quite a few replies to this message, hopefully we'll get this resolved. I am a reader of QST, and I found an article in there which I wish to share:
This is found on page 61 of September 1998 QST:
Q. While tuning outside of the ham bands one evening I heard a female voice that was repeating a three-letter phnetic phrase in english. This went on for at least 10 minutes. Do you have any idea what this is?
A. Congradulations! You've stumbled across an infamous and mysterious numbers station. These stations have been in operation for years and have confounded most efforts to pin them down. Knowledgeable listeners believe that the stations are opperated by the intelligence agencies of various governments, including our own, and that the number/letter strings are encoded messages to overseas agents. most numbers stations broadcast strictly numbers and the broadcasts can be heard in several languages including English, Spanish, German, and Russian. In a few cases evidence points to one intellignece agency or another. the transmission you picked up is believed to originate with the MOSSAD (the Israel Intelligence Service). Transmitter sites include Israel, and Israeli embassies and consulates. In fact, quite a few numbers transmissions have been traced to embassies. If you'd like to learn more about the strange world of numbers stations, get on the web and check out Numbers Stations Info. (http://www.access.digex.net/~cps/numbers.html)
Someone mentioned in another reply to alert authorities on these transmissions. I, myself would not. More than likely they already know that they are there, and (as mention in the article) may have sent them themselves!
That's just my $0.02,

OK, one quick thing to say. Some people heard CW on the radio, and assume it's military. It's not, CW has been long sice abandoned by the mililtary. In some cases they can be beacons(see Beacons Web Page (http://www.airnav.com/navaids/))
Hope that helps!

Having spent a number of years in my youth (I can still remember those days, just) I was a cold war eves dropperl.
It sounds to me that the five letter code is coming from the one Country probably using CW encryption. The big "R".
Hope this helps!
