Special issue of Ham Journal No.44 back in 1986 is an another bible for QRP builder. A SSB generator as 'Kumamoto-city Standard' is the must read article. Using only discrete transistor, still this design is alive and report form completed builders are found in this internet era. In 1980's a group in Kumamoto area was very eager to build homebrew transceiver. Centering a guru JA6BI Mr.Tabuchi, their activity and introduction to beginners are well packed in this periodical from CQ publishing. Ladder type crystal filter and inexpensive measurement instruments are presented in this issue too.
