Dennis,
Impedance matching in audio circuits has not been important since the
days of vacuum tubes with audio output transformers.
Were you operating the KX3 on batteries when you found that oscillation?
If so, the internal resistance of the batteries would be the cause of
the oscillation.
Dennis..
I've had very good results from the several West Mountain
COMspkrs I have.

I searched the KX3 manual and could not find a specification for the
headset/speaker output jack. Last weekend at Field Day I plugged in a low
impedance speaker and got some oscillations above a certain output level.
I want to optimize the impedance match to my computer for FT8 and also know
wh
3 matches
