Just wondering if either of you have done the RF gain calibration before
and/or after the synth board upgrade.

I have noted a similar Cracking in the speaker when listing to AM broadcast
station KFI (640 KHz). At first I assumed it was just overload as I was
using a 160 meter dipole and the signal strength meter was maxed: however
moving to steppir antenna tuned to 40 meters gave the same result with and
smeter reading of only S9.
I have a local AM station on 1450 KHz that produces a -10 dBm into a
spectrum analyzer and -30 dBm on the P3. I had assumed from this, without
making any further checks, that the receiver was just overloaded.
The cracking sound does not sound like any dynamic range problem I have
heard before but I have not taken the time to make any serious tests.
I make these comments because I am not convinced this is any form of
overload and wonder if it could be related to your problem.

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.
