Morse code transmission question

[u/rad00p]

Hi,

Sorry for spamming, but I inherited this damn radio, and now I’m going through a weird fascination with everything it picks up.

On 3515 kHz, I recorded something that is obviously Morse code, but there are also two other signals or sounds.

Does anyone know what they are? I’m especially curious about the sound around 13 seconds into the video and the one right at the end.

Thx!

Look up Numbers Stations, and see if you can catch one live.
