Specifications

If you need to adjust the transceiver drive level during operation you can use

the front panel controls and leave the settings in the Audio Mixer untouched.

Knob TX1 (11) adjusts the drive for RADIO1, knob TX2 (14) adjusts the drive

for RADIO2.

With MK2R+ you can take

advantage of the internal Voice

CODEC to adjust transmit

audio equalization. Click on the

TX Mixer button, select Options

and enable Advanced Controls.

On the Master (Speaker)

channel, selecting the "Advanced" button will open an

additional widow will appear with Treble and Bass equalizer

settings. You can experiment here to adjust VOICE

equalization as well as AGC and bass boost. These settings

will be applied only to VOICE modes because digital modes

use the USB Audio CODEC in MK2R+.

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 80% and adjust for proper drive

with 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.

Note: The TX Mixer button on the digital side of the Audio Mixer tab starts a different sound card

than the TX Mixer button on the VOICE side of the Audio Mixer tab. To check that the proper mixer

has been assigned, click the Get ID button and confirm that the proper sound card is selected. If the

names do not match, restart Router.
