Default Re: FRG-7 Quiet hum

Hi Antony,

I have an FRG7 and have never noticed a hum. I almost always use it on the loudspeaker though so it maybe only a problem on headphones. I guess one option would be to use lower sensitivity headphones or load the existing ones with a resistor. You would then need to increase the audio gain but the hum level should be reduced.
