Fw: KX3 - audio distortion after level 30

[MontyS]

Geez Louise, for $4.08 + $2.98 shipping you can buy a pair of foldable
compact speakers from Amazon.com that will fill your room with audio.
Powered from a USB port or wall wart.  Look for "Black Folding Stereo
Speaker for Apple iPod Touch 4G".  It plugs into phones jack for  input.

Yes, I had the same issue. You can reduce it if you go into the menu and set
AGC*THR to 5 (or 4).  4 will totally eliminate the distortion but will
reduce the maximum volume the radio will produce. For me, (I'm going to say
it) the wimpy audio amplifier is a big disappointment. As you have
discovered, even using an external speaker it does not produce decent
volume.  If I use the radio outside in my patio, headphones are pretty much
manditory. Even with headphones, if my neighbor is mowing his lawn. it can
be difficult to hear. My K2 has enough amplifier that I can just drown out
such noise. I would certainly have accepted a few more mA of current drain
for a decent audio amplifier.

Hello elecrafters,

I fully understand that audio from the internal speaker of KX3 could be
distorted at high level say >30.  However, even I plug in an external
self-power speaker, the audio is still distorted if I set the AF level at
say >30.

Apparently, the audio distortion is not only due to the small speaker but
also caused by the internal audio amplifier within KX3.

Is my observation normal?  I am NOT complaining anything but just want to
make sure that my radio is without fault.

Thanks for your help in advance.

TNX & 73,


Johnny VR2XMC
