W [nn] - Keying Weight
can be adjusted in percentage from 25% to 75%. When set to 50 % the dit time is
equal to the inter-element time, which is normal. Values less than 50 reduce weighting while values greater
than 50 increase weighting. Note that weighting does not affect sending speed because any increase in
keyed time is subtracted from spacing time. Reduction in weighting results in a thinner sound while
increased weighting results in a heavier sound. Since weighting tracks speed, a given weighting will sound
the same at all speeds.
25 % weighting
50 % weighting
75 % weighting
Three Key Weighting Examples
X - Enter Extended Command Mode
An additional set of commands are located in a sub menu. These are commands that are not entered very
often so an additional paddle action is not a significant issue. Extended commands require two entries, an
X
followed by a sub command. Here is the procedure in detail:
Press and hold the command pushbutton and WK will respond with an
R
Enter an
X
and WK will respond with an
E
(command request)
Enter desired Extended Command with additional parameters, if required.
A list of extended commands is provided in the section titled
Extended Command List
found after this section.
Y [nn] - Set Dit/Dah Ratio
:
nn ranges from 33 to 66. Entering
Y 50
sets the standard 1:3 ratio. For
example a value of
33
selects a dit/dah ratio of 1:2 while a value of
66
selects 1:4. The ratio formula is:
Ratio of 1:N where N = (nn * 3)/ 50 example nn = 40 give a ratio of 1:((40*3)/50) = 1:2.4
Z - Change Sidetone Frequency
: After this command is entered the sidetone oscillator will be keyed at a
steady rate with transmit muted. Pressing the paddles will raise or lower the frequency. The range varies nearly
continuously from 300 Hz at the low end to 2000Hz on the high end. It takes a while to sweep through the whole
range. Pressing the command pushbutton will end this command and store the new sidetone frequency. Like all
settings, use the Preserve Settings extended command to save the new sidetone setting in EEPROM.
Extended Command List
A – Pushbutton Input Diagnostic:
is used to verify the correct operation of the switch network connected to
WK input pin. This design allows four switches and a potentiometer to share a single pin on WK. The state of the
network will produce a unique numeric value which WK uses to identify a pushbutton press.
After the Extended
A
command is issued, the numeric network state will be sent in Morse sidetone. For proper
pushbutton operation, the input values must fall within the following ranges:
Command PB ..... 0 to 40
PB 2 ................... 41 to 100
PB 3 .................................. 101 to 130
PB 4 .................................. 131 to 160
To stop this diagnostic state, press and hold either paddle until the readout stops.
C - Toggle Contest Spacing
: When contest spacing is enabled, word space is set to 6 dit times as opposed
to the normal 7 dit times. An
A
is sent when CT space is enabled, an
N
is sent when it is turned off.
E[nn] - First Element Extension:
Forces the first dit or dah of a transmission to be elongated to allow
for receive to transmit delay. Enter a value between 0 and 99 mSecs for nn.
F - Toggle Fast Command Response Time:
Normally WK will enter command mode when the command
pushbutton is pressed for 2 seconds. This may be too long for some operators. When fast response is enabled,
the delay time is reduced to 1.3 seconds. An
A
is sent when fast is enabled, an
N
is sent when it is turned off.
