[Yaesu] FT-1000 60 Hz Audio Hum

[Steve Lawrence]

Marty - My 1000D of approximately the same vintage does not exhibit any 
audio hum. I did have some RF birdie problems which were caused by 
loose screws on several boards. I posted that fix to this list some 
time ago.

and the problem has not returned.

I would suggest that you try cleaning and re-seating all of the 
connectors in the audio chain and look to tighten any loose PC board 
mounting screws you find.

Good luck & 73, Steve WB6RSE
