[Elecraft] KX3 - audio distortion after level 30

[Alan Davenport]

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,
