Re: FRG-965/9600故障
低周波ノイズが出る症状をもう少し詳しく見てみると

・キャリアが出ていない周波数では症状が出ない
・17.5MHz間隔で症状がでるスプリアスが出ている

2番目があやしい。以前は見られなかった症状だ。

FRG-9600のサービスマニュアルを見ると、動作原理として狭帯域(SSB,AM,narrow FM)モードの際の第二局発(TCXO)の源発振水晶17.53MHzとぴったり一致する。本来は二逓倍した35.06MHzだけがBPFで取り出しているはずだが、それ以外も出てきているということになる。



どうやら原因は第二局発回路にありそうである。

問題の部分がすぐに確認できる位置にあるかどうかサービスマニュアルを見て調べてみよう。

P.S

どうやら第二局発はFront End Unit(シールドケースに収まったチューナーモジュール)内らしい...orz
