E07 and a Pirate sending SSTV?

This is the E07 2100z transmission on 6931 AM. You can hear some "digital" QRM just from the beginning of the transmission. It's SSTV. I managed to decode the last part of the SSTV transmission, just after E07 QRT. The actual frequency was 6924.97 USB. Here's the screen shot from MMSSTV (a freeware SSTV program):

MMSSTV shows 14ZK192 as the callsign of the sender. A Google search leads to http://14zk192.free.fr/. Who's this?

A lot of E25 logs!

This morning we had 2 transmissions on 6140 and 4(!) on 9450 kHz. The last transmission on 9450 (ID "222") was over Polish Radio International. The sound samples are trimmed a bit (to get rid most of the 1000 Hz tone and the silent ends). So here we go...

E25 6140 AM 0836z:

1000 Hz tone
804 repeated several times
5488 0301 6511 2157 2589 9588 2447 9952 8795 6115 0301 8721
"Rebeat" x3
...
EOM EOT

(sound sample 1)

The signal was S9 peaking +10dB, carrier began slightly off-frequency.

E25 6140 AM 1019z:

1000 Hz tone
205 repeated
9774 6277 5844 1083 0472 3266 4393 2509 3442 7900
7095
"Rebeat" x3
... audio problems ...
EOM EOT

(sound sample 2)

Note at repeat the machine sounds like having a slower pace. Signal was S9 with peaks +10dB and some QSB & thunderstorm QRN.

Let's see what happened on 9450 kHz ...

The "a" (E25a) denotes a type: (ID), (number 1) , ... , (number n) transmission. These believed to be "control" transmissions. Also all recordings on 9450 kHz made with the receiver set to USB, while the actual TX could be in AM mode.

E25a 9450 USB 1154z:
1000 Hz tone
277 1 2
EOM EOT

(sound sample 3)

The transmission started off-frequency.

E25a 9450 USB 1211z
"Inte Omri" song
830 21 from the mechanical YL
EOM EOT

(sound sample 4)

The signal strength was lower than the previous (and the next) transmission.

E25a 9450 USB 1238z:
1000 Hz tone
785 20
EOM EOT

(sound sample 5)

And here's a transmission over Polish Radio International:

E25 9450 USB 1345z:
"Arouh Le Min" song (the other song by Umm Kalthoum)
222
8111 2061 9711 9810 4916 6472 2366 2183 5413 4651
7691 3668 5764 9317 9756 9711
"Rebeat" x3
EOM EOT

(sound sample 6)

So that's the end of a busy E25 day! Please be warned; tomorrow we might have repeats of some transmissions on 9450 kHz.

E10a calling HNC B on 4114 kHz

After following Mike's hint, I caught E10a calling HNC B on 4114 kHz at 1947z having a strong S9+10dB. The transmission was QRMed by an XJT transmission which went away exactly when the E10 YL QRT at 1949z. Here's a short clip.

Sound Sample from "Friday night: Special mix night"

And here is the sample from the E10 mix occurred on 31 October 2008...
Please refer to my previous post.

Enjoy!

Friday night: Special mix night

Yesterday evening I was hunting for the famous E10 Jammer and I accidentally found the 6842 kHz, 2000z transmission of XPA. The transmission was interfered from the E10 EZI2 transmission from 6840 kHz, also at 2000z. Here's the recording. XPA was very strong (+10 to +20dB) but someone can listen the YL and the jammer.

And another surprise a few moments later! On 2456 kHz (an E10 ART frequency) there was a nice ART/PCD mix! The ART message was a g44 UMHQN and PCD has the long g106 message starting with AEOYY. Both messages were sent complete, till 2023z when PCD ended.

Sound sample will follow...

Jammers, OTHRs and E10 stuff...

This is the Jammer alone, as recorded today at 0446z on 6840 kHz.

This is an OTHR (Over the Horizon Radar) found today at 0447z on 9130 kHz (another E10 frequency) which is not related (I guess!) with E10...

And this is the Jammer who stops after an PCD2 transmission on 4270 kHz, yesterday at 1900z. (The other noises are just QRM.) The fact that the Jammer stops after the "null" xxx2 E10 transmission may be an indication that the Jammer posses a monitoring station somewhere and checks if he jams an actual message.
