I didn't know it made that much difference, Don.  My headset is a much higher impedance and I have plenty of audio with it.  Must be something I don't understand here.  Too late to change the speaker; it's all glued in.  I'll take the amp route.

Stan,

One of your big problems is that the speaker specified in that project is 8 ohms - if you can find a 4 ohm speaker, you will almost quadruple the available audio.

The other solution is to use an amplifier.

Hi folks. I need some assistance. Is the KX2's headset jack "padded"
to protect hearing?

I'm asking because I built the "CW Resonant Speaker" in the current QST
and it works great but the volume is so low that  it's unusable.
