ESC-H – ESC Help Menu
This brings up a brief list of the ESC commands. Each description is intended to be just enough to jog a
user's memory. Use the up/down arrows to view all the selections the menu. If the command letter is
entered, it will be run directly. Otherwise press ESC to cancel the menu.
Control Commands
To issue these commands, the user holds the CTL key down while pressing the specified key. Even though
the commands are shown in caps, the shift key does not need to be pressed.
CTL-C – Start Fast Callsign Capture
A callsign can be captured and saved while it is being sent on the paddles. A detailed description of this
function can be found on page 10.
CTL-E- Send Error Dits
Eight dits will be sent to signify a CW error. This a buffered command causing a # character to be placed in
the transmit buffer. Instead of ^E, the user could just enter a # directly.
CTL-D - Decrement Key Weighting
CTL-I - Increment Key Weighting
^D will decrease weighting by one percent and the ^I will increase weighting by one percent. There are hard
stops at 25% min and 75% max. Value changes are flashed on the status line, W:55 for example, and
automatically updated in the User's configuration.
CTL-L Clear currently displayed text window, either Rx or Tx
Only the window in view is cleared. If the transmit window is in view and actively sending text, transmission
will stop immediately. Use ESC-L to clear both windows at once.
CTL-M - Match Tx speed to CWR Rx speed
A user usually wants to respond to someone they are copying via the CWR at the same WPM speed. When
this command is entered, the transmit speed is immediately changed to the current CWR Rx speed.
CTL-N - Play Serial Number
Use this command to insert the serial number into the text stream. If there is text in the buffer ahead of the
command, that text will be sent before the serial number. The serial number is automatically incremented
after sending it. For information about inserting a serial number into a message see \N in the buffered
command section on page 12. The left and right arrows directly adjust the serial number up or down.
CTL-T - Tune
This places the K45 in tune mode which forces a constant key down condition. Sidetone (if enabled) is
turned on and the configured output is turned on as well. The user has the option of selecting 50% duty
cycle by way of an entry in Configuration Menu #2. Tune remains on until the user presses space, CTL-T,
the paddle is pressed, or the 10 second tune watchdog timer expires. If in Key1 & PTT mode, mode both
the KEY and PTT outputs are turned on. Only one output is turned on in Key1 or Key2 modes. CWR is
muted while Tune is activated. BW will be displayed/flashed on the status line to indicate tune is in effect.
CTL-U - Change User
As mentioned previously, multiple user setups are supported. The current firmware supports two users. The
user is toggled between 1 and 2 every time CTL-U is pressed. When the user is changed a brief user
message is flashed on the status line while the current configuration is changed. Each user has their own
settings and message list.
CTL-X – Insert Exchange Message
This will insert the message string <F12:WRKCALL> DE <F11:MYCALL> into the transmitted stream. It is
treated as a buffered message and will be sent after any text before it is sent. MYCALL resides in slot F11
and WRKCALL resides in slot F12. WRKCALL can also be entered using the fast capture feature, see pg.
10. A slightly faster way to enter this command is with the ENTER key.
INS - Pause Transmit (Insert Key)
This key is pressed when the user wants to temporarily stop transmitting. Whether the K45 is sending a
message or using the type-ahead buffer, transmit is immediately stopped and held until the user presses
INS (insert) again. A flashing H will be displayed on the status line while transmit is held. If the user enters
