Well, I have an old K3 plus new synths, I have the RX EQ set to zero dB
all across its range, and I hear the noises. I would call them short
tone bursts rather than pops, though.

There will be a slight pop when changing bandwidth between 150 and 100
Hz as the K3/K3S disables the RXEQ at bandwidths less than 150 Hz. The
level of the "pop" will be related to the amount of EQ in use *around*
*the center of the passband* (e.g., "pitch"). If for example, pitch is
500 Hz and bands 4 (400 Hz) and 5 (800 Hz) are 0, there will be little
or no "pop". However, if one has 400/800 Hz set for significant boost
there will be a fairly loud "pop" as the level changes.

This is with normal AF gain and CM500 in rear headphone jack.

I just got my K3 back from Elecraft. They did the once over and
installed
the new SYN boards.
I have noticed a "popping" noise in the headphones as I change the
bandwidth
control, but ONLY as I transition from 200 Hz, 150 Hz, 100 Hz and 50
Hz. I
have only checked this in the CW mode.
This popping noise was not there before sending the rig in.
I have the 500 Hz and 200 Hz crystal roofing filters installed, which
is the
same configuration as I had before sending it to Elecraft.
Any thoughts?
Tnx
