S06 on 9135 kHz this morning; parallel transmission heard in the background

A very strong (+10db) and clean signal this morning on 9135 kHz at 0810z, allowed me to hear the audio of a second, weaker, S06 transmission occurring in the background. Initially I thought that since S06 transmits on 7440 kHz (ID 418) at the same time, maybe it was the audio from that transmission. But after listening more carefully, the second YL calls "471"! This is a sample of what I heard. You can hear the second call (471) easier near the beginning of the message.

Is this common for S06? Who knows...

XC "The Crackle" along with E10 ART

It is the first time I've heard of XC, the so-called "Crackle" on HF. The Crackle is more of a "noise" station than a "numbers" station since its content is unknown...

It is now (0746z) up on 6987 kHz. The E10 station ART on 6986 kHz is causing QRM :-) but this does not trouble me; actually it is a "double pleasure"!

This is a sound sample from 6986 kHz (the E10 ART frequency)

And this is a sample from 6987 kHz, from a bit later, after E10 QRT.

You may also try 5135 kHz, during night.

V13 "New Star Broadcasting station" barely audible!

The so-called "New Star Broadcasting station" (ENIGMA: V13) is barely audible right now (1300z) on 11430 kHz. The ICOM R75 is set to USB and the preamp is engaged. This is a sample from the beginning of the transmission, where you can hear the musical intro. The quality isn't so good but still the V13 theme and the YL characteristic rhythm is apparent.

Additional info can be found at:

A better sound sample can be found at:
http://www.enigma2000.org.uk/

And of course you can take a look at the past E2K Newsletters :-)

The station QRT at about 1330z. If you like, you may try again at 1400z on the same frequency, 11430 kHz. Good luck!

E10 on 14000 kHz

E10 is known to transmit on 14000 kHz (exactly at the beginning of the 20m ham band). Last night I got the repeat of a message while listening to the CW portion of the 20m band. Unfortunately I don't know the call (yet).

So this is what's happened yesterday, Thursday 11/06, 2209z, on 14000 kHz USB.
The message was:

m g28 t
ZIFNS OWWLO XJVAE WGPZG MSPTV PORHW QALCX RIHPY XQQMO SBKJI
RMTHL JOOBC NCZAK ZQJYV GJZNR PNQWQ ACJKL WNKMO BPEMR QPMNP
PZKUT ZAJQR OUVBE YNMOA XPCHP UJFLG RHJAT FSFLF
eom eot

UPDATE:
The message belongs to YHF who usually transmits on 2844//3840 kHz at 2200z.
Thanks E10-Agent!

E10 ABC on 5339 kHz, jammed

ABC was discovered in a FTJ frequency. It is on air right now, on 5339 USB with a nice S8 signal. The strange thing is the existence of the Jammer, at the same frequency but with a weaker signal. How odd! Why to jam a station calling "ABC" and nothing else? Maybe the Jammer knows more about the purpose of ABC, with no messages so far... Here's a short sound sample!

E11a this morning

Right now (07:15 UTC), E11a is on 11486 kHz, USB, with a solid S9 signal. A 46-group message (without the initial and ending 77777's, which is E11b) for Agent "389", starting with "07946..." is in progress.

This is the full transmission.

E10 now sends "TMS" instead of "ABC" on 6428 kHz

E10 was calling "ABC" on 6428 kHz the last few days. But right now (1545 UTC), E10 calls "TMS" in AM mode on 6428 kHz. E10 transmissions are carrier+USB but this one is AM. This recording was made with the Icom set to LSB to avoid some digital "rattle" QRM. The signal is ~S7 on LSB with S9 peaks, while it is a more or less steady S9 in AM with +10dB peaks and digi QRM.

E10 EZI2 & E06 mix on 6840 kHz

Thanks to E10-Agent, ENIGMA 2000 members were informed about an exciting E10/E06 mix!

Specifically, on 6840 kHz E06 started calling "190" and moments later the E10 lady was calling "EZI2". E10 ended at 2003z (after the usual 3 minutes) while E06 sent a 71-group message:

190
865 71
72890 71657 88008 19559 03948
...
(Ended at 2016z with fast zeros)

E06 started with with an S6 to S8 signal but after a while he got stronger, S9...+10dB. Propagation effect or just a necessary power-up to "win" E10?

You can listen the entire transmission here. Enjoy!

The elusive S21 Russian lady (or girl?)

S21 Russian Lady (or more likely a Russian girl) is always buried in noise and QRMed by several other transmissions. This time, despite the noise from the nearby thunderstorm, I had a decent signal.

S21 appeared on 3823 USB, approximately at 1845z, calling "323", and then "374" x2, "33" x2, and then 5-figure groups x2. I'm not sure about the first groups...

Ended at 1853z with ??? then 323 374 33 0 0 0.

Here's the whole transmission (not processed).

E25 strange message

My recorder got a strange E25 message on 9450 kHz.

The transmission started at 1207z, at 1208z there was 1000 Hz tone, then at 1213z the song "Inte Omri". After that, at 1216z the mechanical E25 lady started calling "830 26 835" i.e. a "control" message to 830 and a (strange) message to 835:

9999 x8, "Rebeat" x3 at 1221z, QRT at 1224z.

Just a string of eight 9999...

Signal strength was weaker than usual as a typical broadcast station (probably WYFR Family Radio) was in the background. This is a part of the transmission recorded in USB.

E10 Jammers get aggressive

Right now (1830z) there are two Jammers on 4880 kHz. E10 sends a 115-group message starting with "GHRCA..." to ULX, and both Jammers are on the same frequency! Is this a mistake, or a ferocious attack by all means, to ULX?

So far I believe that whoever operates the Jammers, can transmit at most with two jammers. This time he/she decided to use both Jammers on the same frequency.

Here is a part of the transmission. The Jammers sometimes nearly wins ULX. Also take a closer look at their time offset in the following spectrogram images:
There is a ~25ms time difference between the two Jammer signals. Well, you can hear and see that both remain constant in terms of strength (ok both affected by a slow QSB) so I don't think this is a weird propagation phenomenon. If any of you have a different opinion, feel free to post.

The Jammers stopped at 1851z, while E10 continued with the repeat of the message, plus a weaker broadcast station in the background. E10 QRT at 1855z and the BC QRT at 1859z.

Another E17 transmission

At 1452z on 10240 kHz I found E17 sending another 50-group message. The transmission was in progress and ended at 1458z with "538 538 50 50 0 0 0 0 0" (slow zeros). No breaks/restarts this time, even the signal strength was better (S9 with peaks +10 or +20dB).

Audio sample.

E17 found on 8180 kHz

8180 kHz was set on my VFO since earlier this morning, after successfully recording three SK01 transmissions. At 1100z I switched from the E25 memory (do I need a memory for E25? Hihihi!) to VFO, to set an E03a frequency and check if E03a was on air.

And... SURPRISE! The E17(z) YL was on 8180, calling "274" but had several problems, trying to send a 50-group message (274 986 50 30238). She started again and again several times, occasionally having low audio level.

Here is the complete (24 min) transmission.

And here's a typical transmission of E17z. This one logged on 27/11/2008, 0800z, 11170 kHz.

E17z (and E17) belongs to IA family (format similar to E06/S06). E17 believed to be some kind of training net, because of the problematic transmissions. Its sister, E17z, is more accurate :-)

S32 the "Squeaky Wheel" changes tempo

Thanks to Fritz, yesterday we were informed about the new sound of the so-called "Squeaky Wheel" (Enigma Designator: S32) which transmits on 3828 kHz during night, and on 5473 kHz during day.

S32 during night (3828 kHz)

S32 during day (5473 kHz)

LIVE LIVE LIVE!
Ooops! Right now (1643z) S32 sends a message on 3828 kHz! The language is Russian! (That's why it's S32 instead of XSW (the old enigma Designator; in the past we did not know that the Squeaky Wheel sends voice messages).

Here's what I got (a bit noisy...)

Wait till the end of the file to hear the Squeaky Wheel after the OM finishes!

E07 and a Pirate sending SSTV?

This is the E07 2100z transmission on 6931 AM. You can hear some "digital" QRM just from the beginning of the transmission. It's SSTV. I managed to decode the last part of the SSTV transmission, just after E07 QRT. The actual frequency was 6924.97 USB. Here's the screen shot from MMSSTV (a freeware SSTV program):

MMSSTV shows 14ZK192 as the callsign of the sender. A Google search leads to http://14zk192.free.fr/. Who's this?

A lot of E25 logs!

This morning we had 2 transmissions on 6140 and 4(!) on 9450 kHz. The last transmission on 9450 (ID "222") was over Polish Radio International. The sound samples are trimmed a bit (to get rid most of the 1000 Hz tone and the silent ends). So here we go...

E25 6140 AM 0836z:

1000 Hz tone
804 repeated several times
5488 0301 6511 2157 2589 9588 2447 9952 8795 6115 0301 8721
"Rebeat" x3
...
EOM EOT

(sound sample 1)

The signal was S9 peaking +10dB, carrier began slightly off-frequency.

E25 6140 AM 1019z:

1000 Hz tone
205 repeated
9774 6277 5844 1083 0472 3266 4393 2509 3442 7900
7095
"Rebeat" x3
... audio problems ...
EOM EOT

(sound sample 2)

Note at repeat the machine sounds like having a slower pace. Signal was S9 with peaks +10dB and some QSB & thunderstorm QRN.

Let's see what happened on 9450 kHz ...

The "a" (E25a) denotes a type: (ID), (number 1) , ... , (number n) transmission. These believed to be "control" transmissions. Also all recordings on 9450 kHz made with the receiver set to USB, while the actual TX could be in AM mode.

E25a 9450 USB 1154z:
1000 Hz tone
277 1 2
EOM EOT

(sound sample 3)

The transmission started off-frequency.

E25a 9450 USB 1211z
"Inte Omri" song
830 21 from the mechanical YL
EOM EOT

(sound sample 4)

The signal strength was lower than the previous (and the next) transmission.

E25a 9450 USB 1238z:
1000 Hz tone
785 20
EOM EOT

(sound sample 5)

And here's a transmission over Polish Radio International:

E25 9450 USB 1345z:
"Arouh Le Min" song (the other song by Umm Kalthoum)
222
8111 2061 9711 9810 4916 6472 2366 2183 5413 4651
7691 3668 5764 9317 9756 9711
"Rebeat" x3
EOM EOT

(sound sample 6)

So that's the end of a busy E25 day! Please be warned; tomorrow we might have repeats of some transmissions on 9450 kHz.

E10a calling HNC B on 4114 kHz

After following Mike's hint, I caught E10a calling HNC B on 4114 kHz at 1947z having a strong S9+10dB. The transmission was QRMed by an XJT transmission which went away exactly when the E10 YL QRT at 1949z. Here's a short clip.

Sound Sample from "Friday night: Special mix night"

And here is the sample from the E10 mix occurred on 31 October 2008...
Please refer to my previous post.

Enjoy!

Friday night: Special mix night

Yesterday evening I was hunting for the famous E10 Jammer and I accidentally found the 6842 kHz, 2000z transmission of XPA. The transmission was interfered from the E10 EZI2 transmission from 6840 kHz, also at 2000z. Here's the recording. XPA was very strong (+10 to +20dB) but someone can listen the YL and the jammer.

And another surprise a few moments later! On 2456 kHz (an E10 ART frequency) there was a nice ART/PCD mix! The ART message was a g44 UMHQN and PCD has the long g106 message starting with AEOYY. Both messages were sent complete, till 2023z when PCD ended.

Sound sample will follow...

Jammers, OTHRs and E10 stuff...

This is the Jammer alone, as recorded today at 0446z on 6840 kHz.

Spectrogram:

Spectrum:

This is an OTHR (Over the Horizon Radar) found today at 0447z on 9130 kHz (another E10 frequency) which is not related (I guess!) with E10...

Pulse:

Spectrum:

And this is the Jammer who stops after an PCD2 transmission on 4270 kHz, yesterday at 1900z. (The other noises are just QRM.) The fact that the Jammer stops after the "null" xxx2 E10 transmission may be an indication that the Jammer posses a monitoring station somewhere and checks if he jams an actual message.
