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.

Don,
Reasonable question but were taken out of new package for install
into the radio. I measured each Duracel AA battery afterward at
1.53v unloaded. Popping ceased with external 13.5vdc applied, with
either internal speaker or external speakers. Since I do not intend
to every use internal batteries, it will remain a curiosity. I will
run it on 13.5v from either home supply, car battery or portable
sealed-acid battery. I'm beyond the age for mountain climbing or
backpacking. Hiking thru airports is enough!
Now awaiting the 2M module for my KX3.
