Strange repeat of yesterday's live E25 transmission

Yesterday, a live transmission with ID 360 took place on 6140 kHz at 0801z:

7590 1510 6060 3137 7735 4027 3558 1510 1007

Today, a "shorter version" of the above message was transmitted at 0800z. It wasn't a live transmission; the usual pre-recorded YL voice announced the the first five groups of the above message. Since the original message contains a repeat group (1510) it is obvious that today something went wrong (as usual).

A ringing sound (probably a Windows XP sound) can also be heard.

Another strange E25a message

This is another peculiar E25a message recorded today at 0915z, 6140 kHz, USB mode. I am still wondering what is the purpose of the random WinXP sounds.

E25 transmission with severe problems

A transmission with a lot of problems happened today on 6140kHz at 1114UTC. Just listen for yourself. (Note: a constant buzz sound that appears occasionally is due to local QRN)

UNID signal on 9344 kHz

A whistle-like signal is currently present on 9344 kHz, USB mode 1051z:

Signal strength is low but clear.

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.
