36.5 TRANSMITTER KNOBS AND BUTTONS
The Maestro front panel provides several knobs and buttons to control the transmitter.
The multi-function knob at the right side of the front panel controls the microphone level, CW
keyer speed, and transmitter power level and opens the TX Menu:
The inner knob controls the microphone audio level when the transmitter is operating in a voice
mode. When the transmitter is operating in CW mode, the inner knob controls the keyer speed.
A pop-up display shows the microphone level or keyer speed as it is adjusted.
The outer knob controls the transmitter power level. A pop-up display shows the power level,
as a percentage of full power, as it is adjusted.
Pressing the inner knob inward opens the TX Menu. Pressing the knob a second time closes the
menu. Note that the menu can also be opened and closed by tapping the RF PWR annunciator in
the middle of the upper bar of the main display.
Pressing the MOX button keys the transmitter. The button does not operate like a Push-To-Talk
button. Press the button and release it to engage the transmitter. Press and release again to
disengage the transmitter. The button illuminates in red when the transmitter is active.
Pressing the TUNE button causes the transmitter to output a low-power sinusoidal tone useful for
adjusting external antenna tuners and amplifiers. The power level is controlled by the TUNE slider
on the TX Menu. Like the MOX button, the TUNE button does not operate like a Push-To-Talk
button. Press the button and release it to engage the transmitter. Press and release again to
disengage the transmitter. The button illuminates in red when the transmitter is active.
The ATU button engages and disengages the Automatic Tuning Unit. Please see section 24, How to
Operate the ATU for complete details on the usage of this device.
