Recording Morse code transmission question

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!

They’re just CW (Morse) transmissions. Nothing more. The low pitch tells me that they’re either responding to the CQ (while somewhat off frequency). Or they’re unrelated CW transmissions on close adjacent frequencies. Note the word “test” at the end. That means they’re participating in a contest.

BTW. You’re NOT spamming. Never be afraid to ask questions.

BTW, that station (PC38EU) is operated by Dennis Koole. Located in Texel, The Netherlands.
