XSL ‘Japanese Slot Machine’ – 4291 kHz

At about 1317 UTC on Sunday, the 17th day of August 2025, I tuned in to XSL ‘Japanese Slot Machine’, transmitting on 4291 kHz.

XSL is a Japanese military station that transmits data in the form of QPSK (quadrature phase-shift keying) at 1500 Bd. It is known as the ‘Japanese Slot Machine’ due to the signal resembling the sounds made by a slot machine. It operates on several frequencies, including 4291 kHz. The XSL signal is transmitted from the Japanese Maritime Self-Defence Force Ichihara Transmitting Station in Ichihara, Japan. (Numbers 2016)

The XSL signal was first reported on the shortwave bands by listeners back in late 2000. (Rogers 2025)

Below is a video of my reception.

WWV and WWVH – 10 MHz

At about 0703 UTC on Friday, the 15th day of August 2025, I tuned in to WWV and WWVH, transmitting on 10000 kHz.

WWV and WWVH are shortwave radio time signal stations operated by the US National Institute of Standards and Technology (NIST). They transmit time and frequency information 24 hours a day, 7 days a week. (NIST 2025) (Wikipedia 2025)

WWV is located near Fort Collins, Colorado, USA. It transmits on 5 MHz, 10 MHz, 15 MHZ using 10,000 watts, and on 2.5 MHZ & 20 MHZ using 2,500 watts. (NIST 2025) (Wikipedia 2025)

WWVH is located at the Pacific Missile Range Facility, Barking Sands, in Kekaha, on the island of Kauai in Hawaii. WWVH transmits on 10 MHZ and 15 MHZ using 10,000 watts, and 2.5 MHZ using 5,000 watts. (Wikipedia 2025)

WWV and WWVH operate on the same frequencies, and depending on where you are in the world, you will often hear them both. Voice announcements on one correspond to silent periods on the other. WWVH uses a female voice to distinguish itself from WWV. (Wikipedia 2025)

The voice used on WWVH is that of Jane Barbe. She was born in 1928 in Winter Haven, Florida, USA, and died in 2003, age 74, at Roswell, Georgia, USA. Barbe was a voice actress and singer. She was known as the ‘Time Lady’.

Below is an interesting video I found on YouTube.

Below is a short video of my reception of WWV and WWVH.

The overall reception of WRMI was good.
