Biography

I got my first amateur radio license of Class-4 in 1975 when I was 12. I had been active on six meter band by FM, AM, and CW with my rig RJX-601 made by Panasonic, which is 3 watts output portable one.

I was a member of:
JA6YUM, Fukuoka-city Boys and Girls Culture Center ARC, 1976—1981,
JA6YAY, Fukuoka High School ARC, 1978—1981,
and now I am the head of
JA6YCU, Fukuoka University Radio Club.

A member of JARL, IEEE, and a fellow of IEICE: The Institute of Electronics, Information, and Communications Engineers.
