Utility comms on 6140 kHz

My recorder got a QSO on 6140 kHz USB. These are two processed samples recorded at 0806z and 0807z. There is also a weak digital stream, 1000 Hz to <4000 Hz (tone, PSK(?) streams, tone). Any ideas?

E10 FDU along with Voice of Greece

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 young lady

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:

At 0855z a blank carrier appeared and at 0859z a YL started calling "200 3"! This ended at ~0902z. Listen!

Her second and most interesting appearance occurred at 0929z. The characteristic noise was heard when the transmitter turned on and after a couple of seconds the YL started calling "323"! Three minutes later she said "Message" trice and she handed the microphone to the well-known OM for the message:

"8001 5311 7129 4736 8505 3482 0671 3495 3546 5311",

then "Rebeat" x 3 as usual, and EOM EOT at ~0935z. Here is the whole session!

Note that the 2nd and last group are the same, and the 1st group gives the group count (10) and 8 as a serial number.

So that's how E25 sounds in my QTH without RAI. And that's how the long-awaited YL sounds!

E25 loud(?) and CLEAR 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!

The end of summer for E10 YHF agents

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!)

Lots of E25 specials

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!

A nice ART / JSR mix

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).
