[1000mp] Monitor roughness

[Pete Smith]

Ever since my MkV was new, I have noticed that after I transmit for a 
while, the monitor gets rough, whether on CW or voice.  It's been back to 
Yaesu once, for this and other issues, but they found nothing wrong, and 
the problem continues.  Voice signals sound rough, and CW signals less than T9.

Today I was operating in the ARRL DX contest, and I noticed that if I was 
hearing the rough sound in the monitor and switched the IPO button on, the 
monitor sound cleaned up dramatically.

Have other people noticed the same thing?  And if so, what does this tell 
you about the possible origin of the problem and how to fix it?
