Reverse E25

After a hard weekend I'm back! E25 on the air today with another surprise:

• 1241z: Carrier.
• 1242z: 1000 Hz tone.
• 1245z: OM starts calling "780 30 29 788 28 27" then correctly "780 785 30 29..." (Initially he missed 785). Note the countdown!
• 1251z: "780" repeated, then message:

9496 9080 1831 3673 1003 5721 2851 1831

• 1253z: Repeat.
• 1254z: "End of message, end of transmission", then QRT.

It's the first time I see a countdown! Usually the reverse was the case! Here is the recording! Note that some clicks/pops heard are due to a faulty antenna connection. Luckily, it was easy to repair!

Yesterday's transmission:
After listening Sunday's recording, this transmission was the same, but without yesterday's failures! A lot of breaks happened during the calling session (780 785 etc...). Today I was experiencing "technical difficulties"!
