Standalone QRSS/HSCW Operation
The /H and /Q buffered commands allow HSCW or QRSS strings to be sent in standalone mode. (Note that
QRSS speeds are not supported in Host Mode) HSCW and QRSS strings can be aborted with either a paddle
press or a PB4 pushbutton press. Upon abort normal keying speed is resumed.
PTT Functionality
PTT in standalone mode works the same way as it does in host mode. Note that in standalone mode the
maximum allowable value for paddle entry is 99. This means the largest lead-in or tail delay that can be
entered by paddle command is 990 mSec. If you need to enter a longer delay in standalone mode, use the
WK3tools application which allows these values to be entered from the host over the USB port.
When entering a message by paddle and minimal tail time is essential, be sure to end all messages with the
di-dah-di-dah (
AA
) character to prevent WK from automatically appending a wordspace. If there is a
wordspace at the end of a message WK will hold PTT till the end of the wordspace.
Preserve Settings
WK setting changes made by paddle commands are not automatically copied into permanent storage. That
means the settings will be lost if power is cycled. To save the settings permanently, use extended
P
command. Press and hold the command PB until the
R
and enter an
X
followed by a
P
. This will save
current settings in nonvolatile memory so that all settings will be retained on power cycling. Note that
messages are saved directly into nonvolatile memory so the
P
command is not required to preserve
messages.
Restore User Defaults (Warm Restart)
It’s possible that a paddle command could be entered incorrectly which puts WK into an undesired state.
Rather than try to figure out what went wrong, an easier way to handle this is restore settings from
EEPROM. You can do this by either cycling power or by forcing a warm restart. To do the later, first press
and hold the command pushbutton. An
R
will be sent followed by a
MN
(dah-dah-dah-dit) 5 seconds later
which lets you know user defaults have been reloaded.
Restore Factory Defaults
Refer to Page 13 for a description of how to reset factory settings.
Keyer Lock
A lock feature is provided to disable paddle input and message pushbuttons. This is useful when you want to
pack up a battery powered keyer and insure that it stays off with batteries still connected. It is also handy to
lock the keyer paddles to keep little hands from sending “messages”. While the keyer is locked it is held in
low power shutdown mode and draws about 10 uA.. To lock the keyer, press the command pushbutton, wait
for the R, and then enter a period (di-dah-di-dah-di-dah). WK will respond with an L to let you know it is now
in a locked state. To unlock the keyer, press and hold the both paddles closed for about 8 seconds and WK
will wake up and send an R. This is a very reliable lock mechanism because once the paddles are removed
there is no possible way to accidentally unlock WK.
Shortcuts and Speed Ups
Fast Command responses – WK uses
A
for positive responses instead of an
R
or
Y
Cut Numbers on Command Entry – When entering numeric values use cut numbers to save time. For
example when changing the command speed to 19 WPM, use
S U N
instead of
S 2 9
These are the command cuts used in WK: T=0, A=1, U=2, V=3, 4=4, 5=5, 6=6, B=7, D=8, N=9
