内蔵のキーヤーも自作です。回路はARRL 発行の "Solid State Design for Radio Amateurs"という本からとりました。空いた空間にはおもりのための鉛 板を束ねたものが入れてあります。パドルのツマミはレゴブロックです。
The built-in keyer is also homebrewed from scratch. The design is taken from the ARRL book "Solid State Design for Radio Amateurs". The rest of the space is filled with a batch of lead sheets for the anchor. A careful watcher may find that LEGO blocks are used for the knobs.
