Bingo. That makes sense. I've already sketched out a little 386 amp I
can build on a popsicle stick and tomorrow I'll dump my junkbox out on
the kitchen table and go to work. I guess I should start looking at the
manual before I bother people!!
BTW, other than the volume problem I have, this little sucker REALLY
makes the CW pop. And yes, it IS sharp. If I'm not right on, my
sidetone disappears!

Stan,
If you refer to the KX2 Block Diagram (Page 62 of my manual) you will
see that the PH (headphone) takeoff is a low level and the
SPKR(speaker) output has an additional amplifier associated with it.
I think Wayne did this to minimize the current drain when using
headphones, while providing usable speaker volume for fixed/station
powered use. Plugging a resonant speaker without an amplifier into
the headphone jack will result in the low volume that you are seeing.
At least that's the way I understand the design. If you want viable,
fixed KX2 operation, use a follow-on amplifier with the resonant
speaker.

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.
Do I have to take the speaker output directly off the KX2's speaker
terminals to get more volume?
