[Biography]
I was born in 1954 Hokkai-do. When I was 7th grader, a classmate started to study radio, and he was licensed as phone-class ham radio, and his call sign was JA8GWA. Few years later, he surprized us got 1st-class licensee. This examination was very difficult for 9th grade student in Japan.
I was subject to the influence of him, and I came to get interested in radio. I thought that I would like to study audio engineering after graduating from a high school. I entered JEOL Kogakuin (Tokyo, Kamata), and I studied electronics, radio engineering, computer science.
But, my first job at NJK (Tokyo, Shibuya) was a system engineer as a COBOL coder, 2nd was a COBOL instructor, 3rd was an i8085 & Z80 instructor, 4th was a MC6801 coder.
I returned to Sapporo in 1979, I was licensed phone-class (4th class) in 1984, and CW-class (3rd class) in 1985, and 1st class ham radio in 2012.

I'm living in the bottom of a valley which the street lined with large buildings. There are 4 base station of cell-phone, and about 8,000 persons live in 100 meters in radius near my station. Anyone can't believe it!
Therefore, there are terrible electrical noises.
