Re: FRG-7 Quiet hum
But here's another idle thought, the FRG-7, which is not exactly a Hi-Fi receiver, would have been "specified" with the Yaesu headphones designed for comms audio or a very ordinary 2" ~ 4" loudspeaker. Neither have any real response below 200Hz, but your everyday headphones designed for music and centre of the head thumping bass most certainly do. . . . . . . .
I doubt Yaesu cared too much about an ultimate low hum level. . . . . .
