Master (Speaker) channel will open an additional window with Bass
and Treble tone controls. You can experiment with equalization
(Bass and Treble) as well as AGC and bass boost. These settings
will be applied only to VOICE modes as digital operation uses a
different "sound card" - the USB Audio CODEC in MK2R+.
NOTE: Equivalent controls are available in Vista and Windows 7 by selecting the Speakers (USB Voice
CODEC) properties the Playback tab of the Sound Control Panel. Bass and Treble adjustments are on
"Tone" tab and AGC is on the "Custom" tab.
TX DIGITAL (AFSK/PSK/etc. – transmit levels)
These controls adjusts output level for DIGITAL mode operation. If the channel is
active, the green rectangles, one for each radio, will light. If they do not light, click on
the TX Mixer button and unmute master the Volume (Speaker) and Wave controls.
As with the voice mixer, there are four (4) sliders, two for RADIO1 (R1) and two for
RADIO2 (R2). Each pair has a WAVE slider and MASTER slider (the Master Volume
or Speaker control). The pair used for each radio is determined by the Left/Right
channel selector on the Audio Switching tab.
As a starting point, set the MASTER level to about 70% and adjust for proper drive
(normal operating level.ALC for the given mode) with the WAVE slider.
If you need to adjust the transceiver drive level during operation you can use the front
panel pots and leave the settings in Audio Mixer untouched.
Knob TX1 (11) adjusts the drive for RADIO1, knob TX2 (14) adjusts the drive for
RADIO2.
Test Signal: causes MK2R to output a 1500 Hz audio tone for setting the transmit
output level for AFSK digital modes. The radio with transmit focus will be keyed.
