Shortwave SW radio frequency range is from 2.3MHz to 22MHz under HF (high frequency) band, commonly it is used as international broadcast, but strangely SW radio is also used as military communication.
On 26th April 2020, I received unusual radio signal which sound like radio jammer on shortwave radio station in Malaysia, but it is Japanese Slot Machine (Enigma designation XSL).
This "Japanese Slot Machine" is not a casino slot machine, but a nickname of enigma noise because it sounds like jackpot slot machine.
Frequencies that I received are SW 6250kHz, 8313kHz and 8588kHz. Received from Japanese Maritime Self-Defense Force Center in Ichihara, Japan, the distance is 5351km to Balakong, Selangor, Malaysia.
In addition, Japanese Slot Machine (XSL) is transmitted under QPSK (Quadrature Phase Shift Keying) modulation at 1500Bd.
In fact, this Japanese Slot Machine is navy communication radio for Japan Navy Force.
