Thank you for look up my page.

In 1977, at the age of 17, I got a license as a telephone-class ham radio operator in Naha City.
I couldn't buy a transceiver because my family was poor.I lived in a rented house and couldn't have built an antenna.So I decided to enjoy the instrument with Brass Band.
At the age of 23, I started playing the saxophone, and when I quit due to lung disease (COPD), I was 42 years old.
I practiced the saxophone for a short time for rehabilitation, but unfortunately I quit it at the age of 52.
At the age of 53, I assembled a crystal radio with recycled parts from a broken radio.
I was 10 years old when first assembled the crystal radio.
A few years later, I received an amateur radio with my homebrew shortwav regenerative receiver.
I wanted to start amateur radio and I got a third-class radio operator license.
At the age of 59, I studied hard and I got a Amateur First-Class Radio operator license.
An Amateur ham radio station was opened on November 16, 2020.
I'm a 60 years old ham radio operator who loves vacuum tubes very much.
I'm a beginner who has just started learning CW(Morse code and Japanese Morse).
I spend Most of time Assembly transmitters and receivers in my tiny workroom.
