Dave,

If you've never heard of 'pink' noise, then you're probably not a student of
noise.

In noise parlance, 'white' noise is the term that is usually used for
non-bandlimited noise (ie, 'broadband noise'). "Pink' noise, on the other
hand, is a term used to refer to bandlimited noise. In practice, anything
that comes out of the audio channel of a communications receiver is really
'pink' noise, as the bandwidth is limited to a few KHz. On the other hand,
the noise that is incident at the antenna or generated in the front-end is
much broader in bandwidth and is more deserving of the term 'white' noise.

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

What is it??

Hi group.

I wanna know how can I get the FM signal without that nasty 'pink' noise.

I'm not using any kind of external antenna.

Greetings!!
