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.
The default tune rate up at start-up is a configuration item in the VFO menu (see later).
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.
3.2 Keyer speed
The default keyer speed (in words per minute) at start-up is a configuration item in the Keyer menu
(see later). During operation of the radio, the keyer speed can be easily adjusted. Click the
“Select” button once, 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.
3.3 RIT
RIT (Receiver Incremental Tuning) allows the receive frequency to be adjusted while the transmit
frequency (the displayed VFO frequency) remains the same. It is useful if the other station is off-
tune, or drifting; other uses include working DX stations who may be listening on a different
frequency some kHz away from their transmit frequency.
This radio transceiver allows RIT values from -9,999Hz to +9,999Hz.
The default RIT at start-up is a configuration item in the VFO menu (see later). RIT can be easily
adjusted during ordinary operation by double-clicking the “Select” button:
Now use the rotary encoder to tune the RIT. As you do so, you will hear the RIT immediately
applied to the VFO.
The tune rate of the RIT control is again indicated by the underlined digit (here 100Hz). In order to
change the tune rate, press and hold the “Rotary” button (in the rotary encoder shaft) and turn the
