A peculiar message from E25 -- accompanied by a new song

It's been more than a week now where E25 plays a new song as an intro theme.

Thanks to our friend Mr. DXer, the song is "Ahbabena ya eeni mahom maana" ("Our lovers are away") from Farid Al-Atrash. But there's more. A short 3-group message was sent to Agent "000" (!) but the operators don't actually want to reveal this peculiar call. Most of the transmissions lack the call part; like having the volume turned down until the moment the machine is ready to say "Message" three times. Then someone turns the volume on.

The procedure goes like this:

• Music ("Our lovers are away") one or more times.
  
• Audio off or very low ("mechanical" YL calling "0 0 0").
• Audio back to normal calling "Message" x 3 as usual,
• 0669 6676 6682,
• "Rebeat" x 3,
• ...
• "End of message, end of transmission"

In most cases it was difficult or impossible to identify the call, but on 21/05/09, they "revealed" it to us. Here's a sound sample recorded on 23/05/09, 0927z, on 6140 kHz. Note that the recording was made in USB and in the beginning of the transmission the carrier was a bit off-frequency. Some other days the song was repeated 2 or 3 times.

Here's a later sound sample where we're not "allowed" to hear the call. As usual the frequency was 6140 kHz. It began earlier, at 0918z then after 3 minutes of blank carrier (which BTW was off-frequency again), the new song was repeated four (!) times. The sound sample is from the last part of the transmission (final repeat of the song plus msg).

Many thanks to Mr. DXer for identifying the song and alerted the E2K Group for this kind of oddity.
