Biography

Thank you for look up my page.

In 1977, when I was 17 years old, I got a telephone-class ham radio license in Naha City.
However, my family was poor, so I could not buy a transceiver. I lived in a rented house and could not build an antenna.
Because of this, I decided to enjoy music in a brass band instead.

When I was 23 years old, I started playing the saxophone. I continued until I was 42, when I had to quit because of lung disease (COPD).
Later, at the age of 52, I tried practicing the saxophone again for rehabilitation, but unfortunately I had to quit again.

At the age of 53, I built a crystal radio using recycled parts from a broken radio.
Actually, the first time I built a crystal radio was when I was 10 years old.
A few years later, I listened to amateur radio using my homemade shortwave regenerative receiver.

I wanted to start amateur radio, so I got a third-class radio operator license.
Then, at the age of 59, I studied hard and got a first-class amateur radio operator license.
My amateur radio station was opened on November 16, 2020.

Now, I am a 60-year-old ham radio operator who loves vacuum tubes very much.
I am a beginner who has just started learning CW (Morse code and Japanese Morse).
I spend most of my time building transmitters and receivers in my small workshop.
