microHAM microKEYER II User Manual page 31

Microphone Selection:
microKEYER II supports two microphone inputs.
The RJ-45 input on the rear panel supports the stock transceiver
microphone, including any microphone "button" controls – if the
transceiver microphone uses a connector other than an RJ-45, use
the supplied adapter.
The 3.5 mm front panel jack can be configured to support electret or
dynamic headset or boom microphones.
Front: always use front panel (3.5 mm) EXT MIC input
Rear: always use rear panel (RJ-45) mic input
Auto: automatically select microphone. If both microphones are connected, use the front panel
microphone if the footswitch is used and use the rear panel microphone (hand mic) if the
microphone PTT is used.
The black box will show the selected microphone.
NOTE: The black box here and on other tabs in Router is "live." It indicates which settings are
currently in use. When the black box turns gray, it indicates that Router lost connection with the
radio or has expired information (CAT port problem). While the boxes are gray, the settings may not
be correct.
Transmit Monitor:
microKEYER II includes a monitor amplifier that provides 2 watts to
a user supplied speaker. Router will select the audio source to be
monitored based on the operating mode. The monitor level can be
set independently for each source/mode.
In CW, sidetone is selected – the sidetone frequency is selectable
from 338, 450, 675 and 1350 Hz. Sidetone can be enabled for all
CW output or only manual (paddle) input. In voice mode, DVK
output is selected and in Digital mode the sound card output is
selected.
NOTE: TX Monitor contains ONLY transmit audio and CW sidetone generated by microHAM
CODEC. It does not include receive audio from the transceiver.
