A large message sent today by E10 YHF on 7918 kHz at 1130z. It was an 147-group long message starting with IBEIA. Listen it here (it's a bit processed to remove some of the noise). Who knows what this message is; maybe a long, last-moment shopping list for New Year's Eve :-)
HAPPY NEW YEAR!
At 1000z a message for 570 (a relatively rare call) was sent from two transmitters (?) in AM and USB mode nearly at the same time! Listen what happened, as recorded in USB mode. Three persons were involved! The OM with the deep voice, then the OM in USB and his companion who read the message.
At 1029z the same thing happened for Agent 995. Here's the clip, recorded in AM mode this time.
On both cases the OM with the deeper voice started earlier, in AM mode and with the annoying 1000 Hz "test" tone.
Sun's activity is low, but there are signs of a new cycle starting, as solar physicists say. The source of the excitement is a modest knot of magnetism that popped over the sun's eastern limb on 11th December. Read more here. We're in the bottom of the solar activity for a long time now... so just cross your fingers and hope the scientists are correct!
E25 appeared over Polish Radio with a massive S9+10 while PR alone was only S5-S7. Here's a clip of the transmission, recorded at 1347z using the Icom using USB mode to avoid QRM. Note the slight echo. The message was:
g14
4121 4041 9811 5592 8876 1949 8148 7233 0693 0321
1043 9173 6024 9811
They QRT at 1354z.
I wonder: Should I QSL Polish Radio asking about the "strange man" disturbing their English Program? Or more precisely their Listener's Letters program? Yes they do have one, every Sunday!
Hello guys,
I know a lot of time passed since my last Numbers-related post, so I have a small surprise for you!
This is my new radio, an Icom IC-R75:
And of course is tuned on my favorite station... And it's morning, and you can see the signal strength meter...
So now you can see E25 hihihi!
A new edition of rfax.pdf, the well-known radiofacsimile schedule issued by NOAA can be downloaded from here. Happy hunting!
Another brilliant Enigma2000 newsletter is out and I thought to give a try to Gert's Prediction List (which is a handy tool for newcomers and experienced listeners). I tried V07 on 13552 kHz, at 0620z. An excellent signal in AM mode; just a bit low audio. Signal had some QSB but it's clarity was excellent. Here is a short clip, unfortunately no message transmitted (as usual).
So you guys over Europe (and elsewhere), consult the Newsletter for schedules and give a try to V07! Who knows, you may catch a message! No one is excused, the latest NL contains everything a spooks DXer wants!
At 1245z a carrier appeared on 9450 kHz and at ~1250z the YL delivered the control message "785 12, 788 4, 13". At 1254z a brief pause occurred and as this stereo soundfile proves, E25 operators played back the session for a couple of minutes past 1254z.
The Right channel is the beginning of the transmission at 1250z and the Left channel is the playback at 1254z. There are no obvious timing differences (echoes) so the 1250z and 1254z transmissions are the same.
The usual spot of FDU, a presumably test-callsign of E10, is 6210 kHz. As always I was looking for E25 and I was tuning around 6140 kHz. So I stumbled upon E10 on 6210 kHz, calling FDU at 0928z. On the same frequency was Voice of Greece playing music related to the National Holiday of 28th October. E10 was calling "FDU" sporadically so I manage to record only one instance. No message followed. At 0946z E10 was calling FDUK (again with VoG QRM) and at 0951z FDU again. Finally, at 1015z I logged FDU8 without QRM this time!
E25 has a YL operator!I always was curious if the info in the Enigma Control List regarding E25 and its female counterpart is accurate. Indeed, experienced Enigmans are accurate! I was lucky enough to record her twice yesterday (Thursday 18/10) on 6140 kHz:
E25 now can be heard without interference from RAI International. The station ceased shortwave transmissions since 30 September 2007. While this is too bad for RAI, an excellent opportunity now opens for everyone who has the curiosity, will and time available to monitor for E25 transmissions on 6140 kHz.
Now I have a good and clean signal nowadays, but not as strong as 9450 kHz. You can check at any quarter of hour from 0800z to 1100z on 6140 kHz, and of course 1200z to 1300z on 9450 kHz. The mode is usually AM or USB in some cases. Happy hunting, and please report your findings here or to the Enigma 2000 group!
E10 YHF sends very large messages at 0900z/1230z/1900z slots. So YHF agents are back from their summer vacations; having a lot work to do :-)
This is the complete E10 YHF 4-message sent today on 7918 kHz USB, 1230z. It is processed to remove some QRM above 4kHz and lots of crackles probably originating from my neighborhood!
Enjoy! (Especially my good friend Kopf!)
6140 kHz is active but interesting things still happen on 9450 kHz, like this. For less than a minute, a carrier appeared on Sunday 15/07 at 1143z and some background chat was heard. The audio was weak; some DSP processing boost it a little.
Then a transmission followed: 780 788 52 53 63 64 65 66 67 68 69 71 74 then 780 repeated and a 14 group message followed. After the "EOM EOT" another voice said "15 3...", "3...", some bg noises and mouse clicks (?) "...1" and finally they QRT. Here is a sample; be patient to listen till the end of the clip!
Second special: The same day at 1200z again on 9450 kHz calling 275 then "Message" x3 2001 280 x9. An odd message consisting of nine "280". The fact that we can get a correct group count from the first group and 02 as a serial is also interesting. Sample! Note the long gaps.
Third and best special! Two messages for two agents in the same transmission! that happened on 6140 kHz today (Monday 16/07) at 0716z. Enjoy!
For a couple of minutes a fight between E10 JSR (the intruder) and ART happened on 5435 kHz (ART's home frequency) at 1500z. Here is the recording of their "quarrel"!
ART finally sent its g26 ZSWMU message (an old one).
Usually E25 sounds like this here in Crete, in USB mode with RAI interfering. This makes things very hard to me because I always get confused about what the operator says!
Today operators decided to help by increasing their power and playing new music in AM mode. Unfortunately no message followed; the entire session lasted from ~1100z to 1127z. Here is a portion of it. In the beginning only the (strong) carrier is present; in the end you can listen RAI alone. The difference is prominent. I really hope they will keep the new power settings on their transmitter and make my life easier! (And broaden the potential E25 audience!)
S28 the "buzzer" or the "foghorn" (OK it sounds like a truck's horn to me!) is using another frequency except 4625 kHz. Ary warned the Enigma 2000 group that S28 can also be found at 3842 kHz.
Here is a comparison of 4625 and 3842 kHz as recorded in USB mode today at 1920z. 3842 is weaker here and lacks the carrier. Also the tones are decaying, not like 4625 kHz.
If you're not convinced if this is S28, listen them both going in "berserk mode" near the hour (1959z). This time the first one recorded is 4625 kHz.
I logged E10 calling ABC2 in the extremely hot island of Crete (temperature peaked at 43 degrees Celsius!) after a warning sent on Enigma 2000 Group. Very strong signal at 1922z, with slight digi QRM. Here is the sample!
This is an introductory talk about Mathematics and Coding by NHK:

Here is a recording of BRIXMIS Story featured on BBC Radio 4, 11 June 2007, 1900z to 1930z.
Great luck today!
I got E25 on 6140 kHz this morning (0817z) calling "955 21" in USB mode. The frequency was clear from RAI thus giving me a chance for a signal measurement! So E25 was S7 max on 6140.
You can listen the transmission here.
Less than an hour later, at 0901z, E25 sent a message to "570". Signal was in USB, RAI-free but with some QRN. Signal was S5-S7.
Here is the message:
2313 3178 0588 1355 7091 0895 9354 8088 8008 5284
9852 1744 5259
This is the full transmission! I deliberately detune my radio to check if it was an AM transmission or LSB-suppressed. Also you can hear the switchover from the guy calling "570" to the guy sending the message.
And yes, more action followed!
At 0916z a stronger carrier appeared, and it wasn't RAI! Music followed, in AM mode, peaking S9+ but most of the times it fluctuated around S8. So this must be another transmitter on the same frequency!
Music continued and at 0930z an OM started calling "405 425" and then "405" only, under the music! The message was:
8920 8053 9788 0251 0753 8751 1008 0448 4098 8715
5405 7539
Listen what actually happened! Again, an other guy announced the message.
The music session ended at 1021z.
I'm almost sure these was two different transmissions on the same frequency. Today's observations are of great importance, if you also take account the occurrence of another test transmission from at least 0710z (as reported by Mike on E2k Group) until 0816z with a S9+ to S9++ here and S9 at 0710z in UK at 0710z.
I was extremely lucky today; being in my shack to note down signal strengths in a RAI-free frequency :-) instead of the usual record-and-check-later procedure which means no signal strength measurements!
E25 is active on 6140 kHz -- messages are sent in almost daily basis, but I have to recover them from unattended recordings with a lot of RAI QRM. Anyway, one exciting thing happened today on 9450 kHz:
At 1144z there was an OM calling "788 63 62 61 59 52 785 50 46 45" in USB mode and in relatively low signal strength, an AM carrier appeared (very strong) and another OM started calling "788 52 59 61 62 63 785 45 46 50 60"!
This is a recording from the weak signal just before the AM carrier appeared (USB mode).
And this is a recording featuring both guys (USB mode, a couple of minutes later).
The always-exciting world of E25 continues to surprise me...
Listen the Windows OS startup sound and some background chat when the E25 transmission on 9450 kHz, AM mode, began at 0957z. Now (1015z) they're still playing "Inte Omri". Recording made in USB mode to avoid splatter from Radio China International on 9440 kHz (my AM filters are not so tight...)
A new edition of the rfax.pdf HF-Fax list by NOAA is available. I haven't thoroughly compared it with the previous one, but seems to have the latest info regarding JMH. On the other hand, no further info about Rome Meteo, which I'm not sure if it is still on air.
Yesterday Mr. DXer alerted Enigma2000 for the existence of a second E25 frequency, namely 6140 kHz. A message to 880 sent at ~0700z.
And yes, it's true! E25 appeared at 0700z calling "880", under RAI Radio. They sent the same message as yesterday in English:
4621 4401 2895 8976 9541 1828 2294 2785 0932 4621
A bit different format, this time first and last groups are the same, and I wonder if the group containing the group count and serial is the second one: 4401: 44 → 44 is the serial? 01 → 10 is the group count? For the moment, it seems to be. More messages needed to clarify the situation.
ID 880 is entirely new to me; and in contrast to other 8xx IDs, the message was in English.
Listen to E25 under RAI, message to 880.
The moment I'm writing this, 0801z, E25 calls "200 8" (a control message to Agent 200)! This ID heard only once back in 12/3/2005 at 1250z! Wow! A whole new world under RAI....
Listen to E25 calling "200 8".
At 1007z today, carrier and a 1000 Hz tone appeared, and an OM started calling "315", a rather rare ID. Then a 13-group message followed in AM mode:
g13
3284 6390 4131 2962 0255 9232 9142 4133 8427 7405
2188 6390 7695
After the "End of message, end of transmission", the OM started calling again "315" at 1019z! The song "Arouh Le Min" heard at 1026z and then again the OM called "315" and the whole message delivery procedure was repeated. Here is the whole transmission. Signal was lower than usual.
After a little research, I proved that the operators decided to playback the message session. They did it again for Agent 315 in the past. I created a 2-channel audio file, putting in the Left channel the initial message and in the Right channel what I believed to be a playback. If the resulting stereo file sounded without echoes (=timing differences), the second repeat was indeed a playback. Only propagation differences should be present. Here is a short sample of the resulting stereo file. Do you notice any timing differences? I don't.
Second transmission:
E25 appeared again at 1126z, with the song "Arouh Le Min", calling "555" and sending the 13-group message:
g12
9150 9121 3911 4428 3360 2388 1821 8231 9908 8180
7623 3911
(listen!)
A typical message which follows the guidelines of my article in Enigma2000 Newsletter #39. The transmission was in AM mode, with a stronger signal.
A brief "control" transmission from my favorite Enigma, E25, occurred today at 1143z. An OM started calling "785 58 788 45 46 50 52". The transmission was in AM mode.
Next, I'll show you the spectrograms from these transmissions: While recording, I switched to USB and detuned the radio for 1-2 kHz to see if both sidebands are present. Today we had...
S11b is also a member of Family III like E11b. Check your Enigma Control List for details.
This one logged yesterday, 17 May 2007 on 7377 kHz USB, at 1030z:
213/35
77777 77777 08863 84165 37806 82607 83077 75531 73768 05155
31331 43344 83716 12625 28754 15735 07681 58384 55607 04406
57667 74406 55718 05715 56623 77530 74556 70521 71458 71268
37036 10786 10875 77777 77777
Due to low signal strength there may be errors in it! Note there are no 9's in the message.
The format is the same as E11b: "213 cherta 35" repeated, then message, each group repeated twice. The message is repeated again, this time each group spoken once this time.
E11b appeared on 9576 kHz USB mode, at 0845z but with a strong broadcast station creating interference.
0845z:
"233 oblique 36" repeated (a 36 group message will follow for Agent 236!)
0850z:
"Attention
77777 77777 42625 86583 67621 12764 31819 86701 48630 68251
03187 21700 56892 88330 59132 89989 91457 78190 51226 50289
25202 73666 89999 89303 36928 70176 34896 90263 47855 74088
94098 50799 04697 86814 77777 77777"
(each group repeated twice)
Pause every 10 groups. 5 is pronounced as "fiver", 9 as "ninour" and
as usual 0 as "tsero"!
0854z:
"Attention
77777 77777 42625 86583 67621 12764 31819 86701 48630 68251
03187 21700 56892 88330 59132 89989 91457 78190 51226 50289
25202 73666 89999 89303 36928 70176 34896 90263 47855 74088
94098 50799 04697 86814 77777 77777"
(each group repeated once)
0856z:
"Out!"
Listen the recording!
Update 12/05/2007: Is it "6" or "8"?
If you monitor Enigma2000 or this blog, I have mentioned that the third group was 42825 and not 42625. It was my mistake. Noise and BC QRM conspired against me and made "8" to sond like "6". With the help of Mike and some spectrogram analysis, it is proved now that no oddities occurred! The message and the repeat were the same. Here is the proof.
(Hmmm.... Blogger hates animated gifs?)
This is an animated gif of the two spectrograms. The first frame is from the segment "...42?25 865..." of the repeat (the one in question and the noisier) while the second is from exactly the same part of the transmission, when the lady says the same groups, in the beginning of the transmission, being for sure "...42625 865..." (reference).
The number in question is at 0.9 - 1.6 sec of the horizontal (time) axis. Keep your eye on the feature located at 1.1sec and ~2800 Hz.
I also measured the time-distances between prominent features of the reference spectrogram, and compared the results between the spectrograms. No great differences found, so the lady didn't make any mistake! The only one to blame is the BC station and bad luck!
Here are the two sound segments: Reference - repeat. I know -- it is very tricky!
Update 13/05/2007:
Because it is tricky, here is the repeat, processed. It is 6 isn't it?
So the case is finally closed...
It seems that the image I posted earlier from JMH Tokyo HF-Fax Service was the best so far... I have trouble getting a decent image from Japan. The good news? I confirmed all three frequencies (2 new, one old) of JMH. Here is the broadcast schedule, effective 1 March 2007 (source JMA).
This is how E25 kills Voice of Russia DRM when E25 ops decide to transmit. As usual, E25 appeared from nowhere at 1250z for a couple of seconds, knocking down DRM, with a new song and excellent audio quality!
The numbers station E10 (as called by Number fans of Enigma2000 group) is one of the most common oddity noted outside the usual shortwave broadcast bands. Here is a sample message, as logged today on 7918 kHz // 5820 kHz at 1130z:
YHF m g20 t
KEBPM RDPIM IFIXI RPXQZ ZBPBC SKWCY OZOID KHAIS RGBAD PQHWO
VOYVU CUHVQ GDLOR JJCFJ DCKXF NPZQG SDRJF LWVRS JBETN LWOIN
eom eot
Sound clip!
Very nice and noise-free signal!
At 1230z, on the same frequency, a little surprise: YHF3! An unusual call! When E10 has a message, Agent's call is repeated. If no message, the number "2" follows Agent's call instead: "YHF2". Let's see what will happen at 1900z 3840 kHz // 2844 kHz !
The latest HF-Fax frequencies for JMH Japan HF-Fax service are:
3622.5 kHz
7795.0 kHz
13988.5 kHz
(all H24, 120/576)
There is some QRM from a digital station few Hz lower. That caused my decoder to choose 60 LPM instead of 120 so I cropped the resulting image.
The mysterious 13320 kHz station logged again ~1351z. It is not a numbers transmission but a live QSO between two stations. Here is the sound clip!
Here is another sample from 13320 kHz! A bit better reception this morning!
"...LF! LTU, LF! OK? LTU, LF! LTU, LF! Roger? ??? ??? ??? Roger? Roger? ??? Roger? Roger-roger? ??? ???"
The letters are "Lima", "Tango", "Uniform". I can't understand the rest (question marks).
And here is another short one! "OUF, UW! YRC, ZN! WUL, UP!"
After Poacher's post in Enigma2000 group, I logged 13320 kHz USB, 1222-1241z! Very weak! Here is a short clip! It is heavily processed to improve SNR. Noise reduction introduced some artifacts but you can hear the voice much easier that way!
This station was misidentified as V21.
From at least 0800z to 1322z E25 was on air playing oriental music. At my QTH, signal strength was constant S9+. Towards the end of this lengthy test (?) session a song was repeated again and again several times. Listen!
A nice AM transmission today at 1142z, sending nearly the same message to Agent 780. Listen! As a bonus, some background chat is present too! So the OM called "780 785 49 51 788 38 41 45 46 48 50" many times, then "780" a couple of times and then a g11 message followed:
27/04
g11
9546 4111 0310 3238 5429 9388 5757 2587 6001 6341 0310
but yesterday...
26/04
g11
9405 3111 0310 3238 5429 9388 5757 2587 6001 6341 0310
Of course you can spot the difference! The first group is different, but the second, which gives a serial and the group count is legitimate...
26/04 3111 → 31 → 13 = serial, 11 → 11 = group count.
27/04 4111 → 41 → 14 = serial indeed increased by 1 and again 11 → 11 = gc.
Another TX occurred at 1244z again AM, "Arouh Le Min" and an OM repeating "220 4 5". ID 220 is a rare one, last appeared on 17/09/2005 and 01/09/2003 accompanied with musical intro.
I found the latest Shortwave broadcast schedule from EiBi. So who else uses the same frequency?
So we have IBRA Radio at 1200z-1300z without causing too much QRM and then VoR, with a strong digital (DRM) transmission. A little searching can reveal more info about these stations.
Language codes:
PJ stands for Punjabi (India/Pakistan)
HD stands for Hindko (Pakistan)
UR stands for Urdu (Pakistan)
HA stands for Haussa (Nigeria)
The rest language codes should be clear to you :-) If not, take a look at the "readme" file at EiBi.
Transmitter locations (aka Remarks):
t is Taldom-Severnyj (near Moscow) 56N44, 37E38
ka is Kashi (Kashgar) (Xinjiang) 39N30, 76E00
And that completes the "Who's who on 9450 kHz"!
After being absent for a couple of days, I checked for E25 news. A carrier was present on the well-known frequency since 1030z today. At 1244z a 1000 Hz tone was up and later, a guy started calling "780 785 47 788 38 41 45 46" (a rather odd calling session, which anyway implied that a message will follow for Agent "780"). Indeed, that happened, and a 11-group message followed for Agent "780". The tone gone near the repeat of the message. Here is the message:
9405 3111 0310 3238 5429 9388 5757 2587 6001 6341 0310
The 5th group was 5428 then changed to 5429 in the repeat.
And here is the processed sample to remove the 1000 Hz tone. It is recorded on USB and near the end of it I switched for a couple of seconds to AM and then back to USB for comparison, so to make clear that it was a USB transmission. The DRM station interfering is Voice Of Russia. Check here for more info. Scroll down and click next to entries for 9450 kHz.
The guy says "Repeat" instead of the usual "Rebeat". Arabic language has no "p" so maybe that's the reason why E25 operators say something like "Rebeat" instead of "Repeat".
A known frequency for the weird whale-song-sounding or "backwards music" station XM (Attention! Not XW, W for Whale! XW is different, "Workshop", check your Enigma Control List!) is 8707 kHz +/-. Here is a sample from today's song, 0814z.
A UNID signal noted by some Enigma2000 members appeared again on 10683 USB, 0809z. I can describe it as a Jet plus a looping banging sound. But today an XM signal appeared there too!!! Listen! The XM interrupted the UNID transmission. I was lucky to catch this since the station QRT at 0817z. Very weird stuff. Any ideas?
A rare member of the polytones family appeared this morning while checking some E10 slots together with the E10 expert, AlphaVax. This was heard at 0934z over E10 ART, on 5435 kHz! It is XPL. The image shows a spectrogram made with CoolEdit, my favorite sound editing program.
The Enigma Control List #22 states:XPL M12 family
Low Tones (Hz +-3Hz)
It would appear that the low tones are the product of mixing 2 non harmonically related tones, analysis not yet completed but tone pairs identified (Hz +-3Hz), tone product in parenthesis:- 150/235[80], 165/255[90], 180/245[65], 205/260[55], 215/290[75] Hz. Tone/value relationships :- Still under analysis.
I'm doing some HF surfing to find E15 but still no luck... Frequencies to check: 18000, 14727 (discovered by Poacher), 14000, 11170, 11000, 6715 (Greek pirates' favorite also), 5834, 5530 and 4130, all USB mode. Take a look in the current Enigma2000 Newsletter (under E15) and in Newsletter #28 and the accompanying article regarding E15.
On the other hand, E25 appeared this morning on its usual spot (9450 kHz) in AM mode. A couple of transmissions in something like suppressed-LSB mode occurred lately. Personally I prefer AM mode, they sound a lot better, even if they play a little with audio gain and cause distortion.
Here is a sound sample of the 0912z E25 transmission. Too much audio gain in the beginning, then lower gain and background chat. I don't know which song they played. I wonder what the ops say in the background...
Poacher from Russia discovered E15 on 14727 kHz, USB, 0840z: http://strangesignals.narod.ru/audios/unid_signals/END_ROVER.mp3
Here is an old recording of mine (6715USB, 17/03/2005, 0703z). It is the ending of an E15 transmission, saying "Adam Rover (or Robert)" twice (AR AR). It is similar with Poacher's recording so it must be E15!
E15 transmissions with message ended with AR x2 in the past.
Now we will take a glance into an entirely different part of the spectrum. A total lunar eclipse was visible from my location (and almost half of the world). Here is one of the photos I took during totality using a Canon 350D digital SLR and a 300mm f/5.4 lens mounted on a simple altazimuth tripod. Exposure time is 1/4 sec, ISO 1600. Unfortunately it was a windy night so most of the images are blurry.
I thank my brother for letting me use his photo equipment!
Hevelius' drawing of Leo, 1690Those scanning the low HF bands are familiar with the "piping" sound found on 3757 kHz. The "pip" also transmits on 5448 kHz during the day. Most of the time it pips continuously, exactly as its cousin, the "Buzzer" (S28 or formally UBV76), buzzes, but sometimes it sends a message. Today, on 5448 USB, 1520z a YL sent one in Russian. Listen!

Which is very similar to the XSW (S32) text I heard some time ago!
S17c changed their frequencies as a part of its seasonal changes. Usually 5301 kHz is noisy and weak in my QTH. Lately I dial my tuner on S17c try to see what surprise the mechanical YL have for us. Today she called "777" along with a X06 transmission which was stronger. Here it is a sound sample, 5301 USB 1250z. The message was "62027" (as usual a "0" is in the middle).
V02a operators are famous for errors, mixing with M08a or even Radio Havana Cuba. This morning a male voice heard just before the schedule start, on 9040 kHz AM, 0900z. They started with MCW for some moments, silence, and then the new voice of V02 started, with some brief MCW again. Listen here. That's how V02a sounds on AM in my location, 10000 km away from Cuba!
Tom H (Enigma2000) pointed that the voice is actually an older one used in the past. Also some new frequencies found, check Hugh Stegman's Utility World blog.
