Unid 7769kHz
« on: April 07, 2014, 0934 UTC »
Hello all,

This is my first post in this forum.
I've been listening a sporadic and weird CW tx on 7769kHz. This morning started at 9.00z and lasted for abt 2 minutes. Code seems to be manual. Sometimes it can be heard some letters as transmitted by mistake or with variable speed. I know this used to be a M23 freq. Any idea?

Listen to a record at 1000z, today: http://cibermundos.net/cibermundos/websdr_recording_2014-04-07T10-05-48Z_7769.0kHz.wav


Thanks

7769 has also been an M89 frequency.

Right! But I think this tx doesn't seem to be a know pattern or am I wrong?

I've just heard a tx with 2 stations. One was sending several letters to the other. At EOT, the first one asked for a confirmation and signed off. From 1415z to 1427z. Weird!!
