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)
A decent portable receiver and simple antenna allows everybody to discover the sounds, noises and mysteries of the Airwaves. Believe me: there is still life on Shortwave! And many, many mysteries...

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

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!)

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:

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.

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).

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.

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.

This day we had three E25 transmissions, all on 9450 kHz.
Here are the message details and recordings:
1st transmission:
1219 UTC Carrier in progress
1228 UTC The song "Arouh Le Min" from Umm Kulthum was heard
1230 UTC Th YL started calling "555", with irregular spaces between numbers, sometimes the numbers are not "spoken" as a whole.
1232 UTC "Message" x3
9104 6031 8741 0413 3253 8882 6157 7803 8487 0312
8828 2497 8741
1235 UTC "Rebeat" x3
1237 UTC "End of message, end of transmission"
Recording (note, I accidentally switched to USB)
2nd transmission:
1242 UTC Carrier
1244 UTC YL calling "440"
1245 UTC "Message" x3
8237 4031 4710 2377 1161 8115 5905 2141 0105 3069
1730 7939 4710
1248 UTC Pause till 1249 UTC, then "Rebeat" x3
1252 UTC Ended with "EOM" only, carrier QRT at 1308 UTC
Recording
3rd transmission:
1342 UTC Music, "Arouh Le Min"
1345 UTC YL calling "227 17, 220 18 19 20, 222" irregular spaces between numbers
1350 UTC "222" repeated, then "Message" x3
5279 4411 0810 5897 2744 2999 2440 4217 0585 4482
0810
Recording
Note that during the third transmission, a BC station was on the same frequency, but here in my QTH, E25 is much stronger (+20dB or +30dB, while the BC station peaks S7)

I just noticed the existence of a newer edition (9 Feb 2011) of NOAA's HF fax guide. Because it took me ages to download it from their site, here is a copy of it!

Hello,
This is the 1230 UTC E25 transmission on 9450 kHz recorded in AM mode. The young lady has a variable rhythm. I suspect that the operators switched to Windows XP since there are reports of that particular OS sounds accidentally escaping to the airwaves. This may be the reason for the varying speech speed.
Nowadays there are more reports of E25 on 9450 kHz probably due to the improving HF conditions.
Enjoy!

And another surprise from E25!
The transmission began at 1214z on 9450 kHz, with the song "Inte Omri". Then at 1217z, the mechanical young lady, in a faster-than-usual pace, was calling "830 3 835". Then a message to 835 followed:
830 3 835
835 (repeated)
"Message" x3
1020 5555 x19 (an unusual message)
"Repeat"x3 (fast)
"End of message, end of transmission"
Note that the pace was a bit faster, the gaps between phrases/numbers were a bit irregular and the endings of the number "five" were more abrupt than usual.
At 1226z the message ended with the usual "EOM EOT" and then...the Windows XP shutdown sound followed! (And not Windows 98!) After this little surprise, the transmission ended.
Here is (nearly) the whole transmission (A part is missing from the beginning). The "rattling" sound is the digital station who usually interferes E25 when I use AM mode.
So E25 operators upgraded their OS? But yet, the quality of the transmission wasn't as good as expected!

The Buzzer (S28) sounds a bit different today, having a higher pitch. This is a recording made today at 1909z, on 4625 kHz, with the receiver in AM mode.

The YL appeared an hour earlier, at 1115z (it is expected to transmit at 1200z-1400z during winter time) on 9450 kHz, with the E25a message "317 3". A carrier was present since at least 1056z, and had a brief break at 1110z. The transmitter QRT after the end of the message, which ended without "End of message, end of transmission".
Recording.

I just noticed that NOAA has published a new edition of the rfax.pdf which is a guide/schedule for the HF-FAX stations of the world. The guide is dated 13 August 2010.

This is my first post after a long time. My excitement for what's going on motivated me to finally quit my long silence.
The Buzzer (S28) stopped transmitting two days ago. Since then, several people confirmed its absence. Yesterday I found (among with others) that the familiar buzzing sound was back again.
Moments ago (4625 USB, 1834z), I was lucky to hear a test transmission from S28! An OM counting in Russian, then the buzzing sound and "The Swan's Lake"!
Here is the recording! Enjoy!
The web page http://www.uvb-76.net/ has a live feed from 4625 kHz.
