K3-AF Output Z?

[Mike Maloney]

Has anyone measured or know the AF output impedance or that of the internal stock speaker at sidetone freqs?   I'm still looking for an external speaker that can match or better the efficency of the stock one at 700Hz sidetone with 60 deg. deflector.  Ditto with headphones.

Not sure if this is what you have in mind but I am using a MFJ-281
ClearTone speaker with my K3. It is peaky around 600-700 Hz (wish it
were a little lower...). Looks nice sitting on top of the K3 with its
matching colors: white letters on black...
