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).
