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.

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 eight AA
batteries which all tested at 1.53v before
installation - brand new out of the package.
8x1.53 = 12.24v but there is loading so voltage
started at about 11.9v. I noted current was
running about 250ma with radio in SSB and normal
volume level. I guess the radio draws pretty
hard in receive.
I removed the batteries and radio runs normal
with 13.5vdc applied. I guess using 2.2v
lithium or NiHD batteries would work better. I
do not intend to run with internal batteries but
wondered if anyone else has encountered "popping
audio" and is it voltage related? Or is this
related to the speaker physical fit issue with
early models of the KX3? Mine is SN 475 (kit).
