S11b message

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

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 message

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

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...

JMH new frequencies confirmed

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).

E25 stomps DRM noise for a couple of seconds

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!

Two short E10 logs

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 !

JMH Japan HF-Fax service frequencies

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)

Myself have logged 7795 and 13988.5 kHz. Here is today's test transmission at 1300z:
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.

13320 kHz not numbers related

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!
