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?
