Some more peculiar E25 transmissions

A lot activity logged yesterday, 12 December. Almost all of the transmissions on 6140 kHz were troublesome. The machine/software which announces the messages from pre-recorded voice samples, had variable speed. Instead of trying to describe what I've heard, I'll provide the samples...

6140 kHz
0800z: 117 7
(This is a so-called E25a transmission.)

0831z: 701 5611 1430 0201 3579 7977 9425 1253 7669 3650 1430 140
Music started at 0838z.

0845z: 169 2140 1540 1056 1721 1721 7560 3997 6991 2217 3402 0474 1634

1000z: 570 4630 1038 9584 6441 0592 2270 2724 5306

1046z: 880 1810 7111 1099 6196 8979 1069 0704 0618 8111 7852 1810
(A usual E25 transmission this time.)

9450kHz
1245z: 555 2121 2021 0110 6422 7056 5601 3046 6436 7646 1768 2820 0110
(Another usual transmission.)

All signals were strong in my QTH. (As I could judge from the (auto)recordings quality.)

There is a chance that the 9450kHz transmission will repeat today, December 13th. Any logs are always welcome!

Two nearly incomprehensible E25a transmissions

I have no idea why E25 operators mess things all the time.

The first transmission occurred today at 0802z with the E25a message "364 91" and the second at 0815z with the message "126 48". Both were on 6140kHz and in AM mode.

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!)
