この自作機械は私の作ではない。製作者はJA0BZC矢花さん。私から敢えてお願いして作って頂いたものである。同じ松本市在住の矢花さんは根っからの自作アマチュアで、知る人ぞ知る無線機づくりの大家。HFからSHFまで自作機器で運用されているが、中でも真空管のリグづくりには独特の設計製作センスをお持ちである。

ある時、シンプルな28MHzCWのQRP送信機のリクエストを出したところ、快く応じて頂いた。周波数の可動レンジと終段管（5763）だけは指定させてもらったが、出来上がりは期待していた以上に可愛らしく魅力的で、かつまた十分実践的でもあり、すっかり気に入ってしまった。Ｅスポが開けたときにはこの送信機に灯を入れ、国内局を呼びに回っている。製作は2014年。
28.0-28.076MHz CW 2Watts output with variable power control down to +3dBm
continuously, cathode keying, AC100V
This isn't my own making. The manufacturer is JA0BZC /Takao Yabana. Mr.
Yabana who lives in Matsumoto 5km north of my QTH loves radio equipment
making, and is famous and known to people in the know. He is active on
from HF to SHF with home brew radio transmitter and receiver, and he has
a well skilled sense especially in design and making of a vacuum tube rig.
I have felt strong admiration in this point from before.

When Ｉ requested him to make a small 10m CW QRP transmitter for me, he
consented to that pleasantly. The completed TX was pretty, attractive and
also practical enough more than expected, and it has been liked completely.
When “sporadic-E” opens, I sometimes call the domestic stations with this
transmitter on 28.050MHz±20kc. This was made in 2014.
