The Tap/Hold Rule
Each of the push-button switches on the front panel has two functions,
one activated by a TAP (short press) and the other activated by a
HOLD (long press, about 1/2 second). The upper label on each switch
shows the TAP function (white lettering), and the lower label shows
the HOLD function (yellow lettering). To highlight this in the text, we
use two different typographical styles to identify switches:
T AP
and
H O L D
.
Accessing the Configuration Menu
Tap
M E N U
to enter the KX1’s configuration menu. You should
see LED on the display, which is the first menu entry (display
brightness setting and timeout period). Try rotating the VFO knob,
which scrolls through all 16 menu entries.
Use the knob to return to the LED menu entry. Then hold
E D I T
to change the LED parameter. The display will change to L
followed by a number from 0 to 6.
Tap
B AN D
and
R I T
to change the display brightness. Settings of
2 or 3 are about right for indoor daytime use, 0 and 1 are suitable in
low lighting, and 5 or 6 in bright lighting. 2
Rotate the VFO knob to select the desired LED timeout (5 to 60
seconds or INF for infinite, i.e. never times out. As you rotate the
knob, the timeout period is flashed, e.g. t10 for 10 seconds. (Note:
When the LED times out, it will go blank. However, in very low
lighting or darkness, you may see a slight residual illumination.)
Tap
M E N U
once to return to menu scroll mode, then tap it again
to return to the frequency display.
2 CW feedback on switch-press can be used in lieu of the display. This is
described in the Operation section.
Frequency Display and Band Change
The display shows three digits of the operating frequency. Which three
digits are shown depends on which tuning rate you’ve selected: 1 kHz,
100 Hz (default), or 10 Hz. At 7100.00 kHz, the three tuning rates
produce the following displays:
7100.00 7100.00 7100.00
To select 1 kHz steps, press and hold the VFO knob (from now
on, we’ll indicate this as: hold
1 k H z
). Then try rotating the knob. No
decimal point is displayed at this step size.
To select 10 Hz or 100 Hz steps, tap the VFO knob (i.e., tap
1 0 / 1 0 0 H z
). The tuning rate alternates between 10 and 100 Hz steps
as you tap, and the decimal point moves accordingly.
You can check the MHz and kHz digits at any time by tapping
B AN D
. For example, if the VFO frequency is 7100.00 kHz, tapping
B AN D
will first show 7 , then 100, then return to the appropriate
display for your selected tuning rate.
To change bands, tap
B AN D
twice, quickly. This will trigger the
MHz-kHz display, in this case showing 14 then 100 (14100.00 kHz).
(Tapping or double-tapping
B AN D
also stores the present frequency
for the next power-up or band change.)
Set the POWER switch to OFF.
Disconnect the power source from J1.
Remove the VFO knob and set it aside for reinstallation later.
Wrap the cover and put it in a safe place until it is needed.

Leave microcontroller U1 in its socket during the
remainder of the assembly process. Be sure to observe ESD
handling precautions at all times.
