7 AMATEUR RADIO CARRER
 I started an amateur radio operator from 1973.
After graduating from junior high school, I suspended from activities.
  When I was a graduate student, I resumed my activities and focused mainly on mobile operations.
 After that, while working for the Japan Air Self-Defense Force, the activity was suspended again.
 Currently, I retired from the Self-Defense Forces, returned to my parents' house, and resumed activities.
 The current major bands are 7MHz, 14MHz, and the modulation type is FT8, SSB and sometimes CW.
 The radio I'm using is Yaesu's FTDX-101MP, and the antenna is a full-size dipole with a height of 10 meters.
 I am planning to build a full size dipole antenna for 3.5MHz this year.
