Why "the pip" named S30

Those 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!

Update 4/3/2007:

Mike provided a translation to Enigma2000 Group:

And a translation of what you heard!

Which is very similar to the XSW (S32) text I heard some time ago!
Thanks Mike!

S17c calling "777" plus X06

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 new voice, old habits

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.

S17c with a different callup

HFD from E2k Group noted that S17c used s different callup sequence, instead of the known one: "555"x3, "313"x3, 05 etc. Today, she said "777"x3 instead of "555"! Listen! 9165 USB, 1250z. A very good signal on my QTH, but i did some processing to reduce noise!

E25 test & voices again

This is the beginning of the test transmission started at 0815z and ended ~0833z on 9450 kHz this morning. Again there is a weak conversation in the beginning, and when the music started, the people talking, can be heard easily.

It will be very interesting if E25 start transmitting more frequently. More messages to gather & analyze, and more opportunities to other Numbers fans to listen! I wonder if this will evolve to a 0830z-1030z-1230z schedule!

E25 morning tests

This is a recording of the beginning of a test(?) transmission from E25 this morning (9450 kHz AM, 1032z). Except that it proves the existence of other broadcast times than ~1200z-1300z, it is very interesting because an entire conversation can be heard in the background. If anyone can hear & translate it, is welcome to post a comment and make me happy!

The E25 saga continues

For several days I have noted activity on 9450 kHz at 0800z. Yes, that early! Let's unfold this story first:

Monday 5 February
A carrier noted on 9450 kHz at 0756z. QRT at 0759z

Tuesday 6 February
0753z carrier up! 0754z music, the familiar style of E25! Definitely E25. QRT 0810z

Wednesday 7 February
0749z carrier! Music! "Arouh Le Min" QRT 0800z

And today the surprise:
0823z carrier on 9460 kHz coming and going. Weaker than previous ones. These were as strong as the English E25 transmissions ~1245z. 0826-08028z series of test tones of different frequencies. Maybe it is not related to E25 but is a very interesting event.

Noon:

  • 1211z: Carrier, "Inte Omri" music intro.
  • 1217z: "830 16" weaker signals than usual. Read on.
  • 1244z: 780 788 27 28 785 29 30 repeated, the usual excellent signal strength now.
  • 1246z: 780 repeated, "Message" x3
1319 2160 1111 1754 2130 1111

This message reached USA! Chris of SpyNumbers had the luck to log E25 today along with other people on #wunclub!
  • 1248z: "End of message, end of transmission", QRT. Listen! "EOM" is at 4min 51sec.
Tip: Messages to "8xx" are in Arabic and with reduced power/different beaming. Analysis in progress!

Too tired now... 73!
