Biography

Hi, I’m Yasu.
Callsings: JK1PKJ / WA6V
Location: Tokyo, Japan

I was first licensed as an amateur radio operator in 1977 while I was still in high school, and obtained my CW endorsement the following year.
I later earned a First-Class Radio Operator for General Services license, allowing me to handle all types of radio operations.
In 2026, I also obtained my Amateur Extra Class license.

Operating Style:
I am mainly active on CW and digital modes.

I always enjoy making contacts with amateur radio operators around the world.
Please feel free to call me — looking forward to working you on the air!

73,
Yasu
