It is well worth remembering while you are familiarizing yourself with the operation of the radio,
that if you get into any unexpected function or menu – you can nearly always press the “Exit”
button to cancel and get back to the main operation mode.
Each of the buttons may be pressed once, pressed twice (a double-click) or pressed for a
long-hold. This facilitates three different functions for each button.
The laser-etched captions on the QMX front panel act as a reminder of the main functions
of the various buttons and controls.
4.1 Tune rate
The right-hand rotary encoder tunes the active VFO. The rate of tuning is indicated by the
underline cursor. In the example below, the underline cursor is under 100Hz digits. This means the
tuning rate is 100Hz. If the cursor was under the comma , this would mean a tune rate of 500 Hz.
The available VFO tuning rates are 1kHz, 500Hz, 100Hz or 10Hz.
A press of the “Rotary” button (in the rotary encoder shaft) causes the tuning rate to change, in the
cycle 1kHz -> 500Hz -> 100Hz -> 10Hz -> 1kHz etc.
You can also press-and-hold the rotary encoder shaft button, then turn the rotary encoder
to move the cursor to the left or right; this allows selection of steps up to 1MHz; turn the
rotary encoder within 0.3 seconds of the button press.
4.2 Keyer speed
During operation of the radio, the keyer speed can be easily adjusted. Click the “Select” button
once (also indicated by the text “. Keyer” on the enclosure, and the speed will be displayed on the
screen:
A14,006,50
Speed 12
Now you can adjust the speed using the rotary encoder. Press any button to return to the main
operating mode. You may operate the radio while the Speed setting is shown. You can also press
the rotary encoder shaft button to select sending a stored message, while the Speed adjustment
setting is active.
Setting speed to 0 enables “Straight” Key mode regardless of the keyer mode setting; this is useful
for quickly being able to key down for antenna tuning purposes. It is much easier than going into
the Keyer menu, selecting straight key mode, doing the tune up, then going back into the menu to
change to Iambic again. The normal configured keyer mode is automatically restored when you
increase the speed above zero.
