Jay,
The K3 "H" or "L" in the mic select do *not* refer to microphone
impedance, but to the range of the K3 microphone gain. The Heil HC4 and
HC5 elements (and other low level output microphones) will need the "H"
setting. Most other microphones can use the "L" setting.
If your microphone has an H and L switch, that *does* refer to the mic
impedance, and it should be set to "L" for use with modern transceivers
which use a low impedance microphone.
You said "headset" which tells me you are referring to SSB rather than
the Data mode setting question of the original post. For SSB use,
adjust the Mic Gain control to give you 5 to 7 bars on the ALC meter.
The K3 "ALC" meter is a combination of a 'VU' meter and an ALC meter.
The onset of ALC is indicated by the 5th bar. Those bars below the 5th
are an aid in setting the correct audio level (especially useful for
Data Modes).
This is all in the manual - refer to the mode you are using - Data or
SSB and set up like the manual indicates.

As a K3 newbie here, would the mic impedance (H or L) be a possible
issue? I could not get any ALC movement until I went to H impedance
for the Heil headset I have. I was then able to get all the ALC needed
with the mic gain.
