Unknown repeating Morse signal on SW around 4.5 MHz – anyone know what it might be?

Hi everyone,

I received a repeating Morse-like signal on shortwave around 4.5 MHz.

Date: February 8, 2025

Time: around 21:46 (local time / UTC+8)

Location: Indonesia

The signal sounded like repeating CW/Morse continuously.

I’m still learning about SW and RF, so I’m curious what this could be.

Could this be a beacon, utility station, or something else?
