Pray tell, in 50+ years of ham radio I have never heard 'pink noise'.

What is it??

SNIPPED

I just used NCH tone generator to make pink noise - sounds
like what you hear on a AM when you open the squelch. I can
email you a sample if you'd like. :-)

For years we called that 'white' noise or 'background' noise.

Now, with a full quieting signal, 20 uv, if it's being heard on FM I'd suspect
the discriminator or limiter circuits. I'd start looking at the limiter.
