# Terminal

This tab is intended to demonstrate your K3's CW and Data Mode decoding capability.

The page is divided into four areas:

- At the top are buttons to choose the data mode, to start or stop transmission, to clear the input and output areas, and to select options. A list of prosign shortcuts is displayed when in CW mode.
- There are 16 "message memory" buttons for frequently sent text such as CQ, call sign, signal report, "brag tape" information, etc.
- There is an output window that shows text decoded by your K3 in black, intermingled with characters you have transmitted in green.
- Finally, there is an input area where you may enter text to be transmitted.

#### Data mode buttons

These buttons select one of three "banks" of message memories. There is also mode-specific processing. For example, an equal symbol "=" is translated to the BT prosign in CW.

The K3 Utility does not change the K3's Mode, Data sub-mode, or Text Decode settings. Use the K3 Front Panel MODE, DATA MD, and TEXT DEC buttons to select the desired Mode (CW or Data sub-mode FSK-D or PSK-D), and enable Text Decode. Receive-only Text Decode is available in AFSK-A, but the KY command used for transmit requires CW, FSK-D or PSK-D. If no characters are sent, or sending seems to "stutter", it may be because your K3 is in an inappropriate Mode or Data sub-mode, or Text Decode is not functioning. See the Elecraft K3 Owner's Manual sections on Data Modes and "Advanced Operating Procedures: Text Decode and Display" for details.

#### Transmit

This button is a toggle. Click it once to begin sending characters in the input area. Click it again to stop sending.

The button's caption changes to "Stop" while transmitting.

You may also toggle transmit with the Ctrl+T keys (press and hold either Ctrl key, then tap "T") to toggle transmit. Pressing Ctrl+T once to begin sending characters. Press Ctrl+T again to stop sending.

When all pending text has been sent, transmit (RTTY diddle) is turned off after a short period, influenced by "idle timeout milliseconds" in the Options dialog and [TXOFF] in a message memory.

#### Edit Memories

Opens a dialog to make changes to the Message Memory buttons.

There are three separate sets of 16 "memories" for CW, RTTY, and PSK31.

Message memories may contain specific bracketed uppercase strings that are interpreted when the message memory is "played back" or copied into the input area. These strings are:

[CRLF]
  is replaced by a RTTY carriage return / line feed or a PSK31 new line character.
[NL]
  is replaced by a RTTY carriage return / line feed or a PSK31 new line character.
[TXON]
  turns the tranmitter on when this message memory is "played".
[TXOFF]
  temporarily disables the idle time delay after all characters are sent.

For example, my first message memory contains [CRLF]DE K6KR [TXON][TXOFF]. Memory 2 contains K6KR [TXON][TXOFF].
When I press CTRL+1, [NL]DE K6KR is copied to the input area, then transmitter is turned on (because of [TXON]), and my call sign is sent.
I can press CTRL+1 to send my call once, or CTRL+1 followed by CTRL+2 if I want to send my call sign several times.
As soon as all the input text has been sent, "diddle" is turned off, without waiting for the Idle Time delay period, because of [TXOFF].

These "Message Memories" are different from the K3's built-in CW Memories described in the Elecraft K3 Owner's Manual. The K3 CW Memories may be used for CW or Data mode messages that are sent by pressing the K3's front panel memory buttons, without need for a current connection to the K3 Utility program.

#### Clear

Erases the text in the output window and unsent text in the input window.

#### Options

Opens a dialog to set terminal page options:

##### Idle timeout milliseconds

Influences the time that the K3 transmitter (RTTY diddle) remains active after all input characters have been transmitted. The default value 0 ends transmission when input characters have all been sent. The maximum value for this parameter is 99999 milliseconds, almost 100 seconds.
If this value is more than a couple of seconds and the transmitter buffer is emptied, the K3 Utility Program sends a non-printing sequence (space, backspace) every few seconds to keep sending "diddle" while you think about what you'd like to type next. Press CTRL+T or ESC to turn off the transmitter immediately.

##### Font

Opens a font selection dialog to choose the font for the input and output windows.

#### Message memory buttons

These buttons transfer the associated text into the input window. Click the "Edit Memories" button to make changes to the Message Memories.

Note: These "Message Memories" are not the K3's CW messages described in the Elecraft K3 Owner's Manual.

Keyboard keys Ctrl+1 through Ctrl+0 perform the same functions as clicking Message Memory buttons 1 through 10, but you don't have to reach for the mouse.

#### Output window

This read-only area is used to display text decoded by the K3. Text sent by your K3 is shown in green as it is transmitted. Text you receive is shown in black.

#### Input window

At the bottom is a multi-line input area where you may enter text for transmission. Click the Transmit button (or press the Ctrl+T keys on the keyboard) to begin sending data. As characters are sent to the K3, they are colored gray to indicate that they may not be changed, as they have already been sent to the K3 for transmission. Characters that have not yet been sent to the K3 may be changed.

##### Input Window Shortcut Keys

- Ctrl+T ("transmit") is a "toggle" that is equivalent to clicking the "Transmit" button.
- Ctrl+W ("wipe") removes all unsent characters from the input area.
- Clear (the Numeric Pad 5 key, often unlabeled) removes all unsent characters from the input area.
- Ctrl+1 through Ctrl+0 are equivalent to clicking message memory. buttons 1 through 10.
- ESC stops transmission as soon as possible.

The bar that separates the input from the output area may be moved vertically by dragging it with the mouse.

##### Prosign substitution

A number of punctuation symbols are used to represent CW prosigns. For example, to send the prosign BT (-...-), type the "=" sign into the input area. A reminder list of available prosigns is shown near the top of the Terminal page when in CW mode.

Symbol | Prosign | Morse
--- | --- | ---
_ | AA | (.-.-)
+ | AR | (.-.-.)
% | AS | (.-...)
= | BT | (-...-)
( | KN | (-.--.)
* | SK | (...-.-)
! | VE | (...-.)

See the Elecraft K3 Programmer's Reference KY command description.

## Known Limitations

- Received Carriage Return, Line Feed, and Newline characters are displayed as spaces.
- The ITA-5 alphabet for PSK 31 is incomplete. Upper case characters are transmitted in lower case. The left and right braces {}, vertical bar |, and tilde ~ are not transmitted.
- Semicolons are not transmitted. The semicolon is used as a KY command delimiter. If you enter a semicolon, the K3 Utility replaces it with a comma.
