See if you hear it with no antenna connected (or switch to ANT 2 if
nothing is plugged into it).
That will tell you if it is some kind of noise that you are picking up
or if it is being produced in the radio.

There are times that I have noticed a crackling sound in my headphones
with my K3S. This is not the normal band noise static that has depth, this
crackle sound seems very close to my ears. I first noticed it with my
Heil headset and I tried wiggling the connection, changing the RX EQ
settings and turning on noise reduction but nothing had any effect. It
randomly comes and goes and I think I have also heard it on TX. I thought
perhaps it was related to the Heil brand headphones. Last night I plugged
in a new Sony professional headphone and the crackling sound was very
strong for a few minutes and then eventually went away. I have never
experience this with any other radio and I have no idea what is causing it
or how to make it go away.
