Ed,
Were those good quality, name brand batteries? I have heard similar
popping noises from audio amplifiers caused by batteries with high
series resistance. I have not observed that problem with the KX3, so I
am just suggesting that the problem may have been the batteries.

While on my trip in the lower-48 I installed batteries in my KX3 for
the first time (run it off 13.5v PS in the shack).
I noted that there was a regular popping noise at a regular beat
about once per second. I checked battery voltage and saw that is was
below 12v and dropping slowly. I used
I've not noticed any such sounds, Ed, but my
hearing is not exactly reference standard.
I'm using Eneloop NiMH and have the optional
charger so they can stay in the KX3. So far, so
good -- though I'm usually on 13.8 VDC or an
external battery if available.
