村上無線へようこそ。
元テレビマン・アマチュア無線局 JH2DJZの局長が発信しています。
テスターの使い方の解説や、電子工作・実験の楽しさを独自の視点でお届けします。
「Made in Japan」の精密なメカニズムをこよなく愛し、グランドセイコーの精緻さ、SANWAテスターの信頼性、そして8年愛用したアクアハイブリッドの耐久性に、技術者としての誇りを感じています。ただしオーディオでは、神と崇めるJBLサウンドへの情熱も忘れません。
ラジオ工作、腕時計の解説、接着剤の使い方から、真空管アンプの実験まで。
「やってみなけりゃわからない」
村上無線が独自の視点で、時に誰もやらないような「変な実験」も全力で楽しみます。
技術と好奇心があれば、世界はもっと面白くなる。そんな発見を、あなたと共有できれば幸いです。
