Any ideas?

E25 test transmission this morning on 9450 kHz

This morning I was lucky enough to receive an E25 test transmission on its "noon" frequency, 9450 kHz. It began approximately at 0800UTC till 0827UTC. Most of the time it was only a carrier, but occasionally there was the 1000 Hz test tone, which surprisingly, at 0819UTC and 0824UTC varied in frequency. This recording is from 0817UTC onwards. At 2min 40s and at 6min 40s of the recording, the operator varies the tone frequency (no, I didn't change my receiver's frequency!)

Chile HF-Fax service log

And here is a HF-Fax log!

This is the schedule transmission logged from Chile CBV HF-Fax service, logged on 29 July 2155UTC, on 17144.59 USB:

171446.4 kHz 2155z

Many thanks to Nairam for providing the tip! He had better reception than mine as you can check his images here (schedule) and here (+36h prognosis). The transmission ended before the completion of the full schedule image.

73!

E25 transmissions

There were two transmissions on 6140kHz today. The first one ended just before the final two numbers of the message, while the second one was an E25a transmission.

Here is the 0833z transmission, and here is the E25a transmission at 0848z.

Also, two test-like transmissions occurred on 9450 kHz, the first at 1209z and the second on 1239z. The former was just the usual 1000Hz test tone while the latter, except from the tone, had ~10 seconds of music, which was something new this time.

Here is the sample from the second transmission on 9450kHz.

E25a transmission at a furious speed

Yesterday, a very strong carrier appeared at 1304 UTC on 9450 kHz and after ~10 minutes (1315z) the usual E25 lady announced an E25a-type of message:

785 56 788 49 52 53 55

Initially the YL said "788 9" instead of "788 49". That was her mistake. It still needs practice and patience to follow her. It is odd that sometimes, when the number which follows is the same, the pause in between is bigger.

The strange (and funny) thing is that after the end of the transmission, at 1321 UTC, the YL started again, in a frantic pace. Then, at 1323 UTC, she was repeating "78" and then "Message" x3, "Rebeat" x3, "End of message, end of transmission" and a couple of WinXP sounds (the kind you get when you are browsing with Explorer" were heard.

Anyway, here's yesterday's recording (trimmed for brevity).

Two E25 transmissions on 9450kHz, with lots of PC sounds

The recording starts at 1315z on 9450 kHz, AM mode. After the first transmission and during the second transmission, a lot of PC sounds are heard. Any ideas?

Another transmission occurred on 9450 kHz at 1244z (a message to 440, which is the same since 22/02). Also, earlier this morning, a transmission occurred on 6140 kHz, at 0800z:

6421 4880 3351 9836 8953 3361 4186 6507 3344 4586 4880 5390

The station was up at least since 0753z with OM music. WinXP sounds were heard again, the YL ended with “EOM 3...”. It was a strong signal.

WinXP shutdown sound after an E25a transmission on 9450 kHz

Today there was a transmission on 9450 kHz at 1313z. The strange thing was, while being an E25a transmission (which means no message body), the YL said "Message" three times, and continued to call "785 46". Usually, a runaway "Message" can be heard during E25a messages but in the end of the transmission. After calling "785 46" a couple of times, the YL said "Message" twice, and the WinXP shutdown sound was heard.

Here is the recording of the full transmission.
