PRE-PROGRAMMED MESSAGES
There are eight preprogrammed message buffers available. To LOAD the buffers: Press Ctrl + the corresponding function key (F1 through F8). Press TAB or click OK to end buffer data entry. To SEND the programmed messages press the corresponding function key (F1-F8).

SETUP
Use Setup to change the setting of the COM port (1-4), Beacon delay or tone frequency (default is 600Hz).

CHANGING CODE SPEED
Code speed can be changed by using the adjacent spin buttons or the up-down arrows. Available speeds are: 5, 7, 10, 13, 15, 18, 20, 25, 30, and 35 WPM.

SOUND
Sound can be toggled with the switch in the lower right corner. Click '1' to turn it on, click '0' to turn it off. The pitch can be changed incrementqally by using the Page-Up and Page-Down keys or set to a specific frequency in the main menu under 'Setup'.

TRANSMITTER KEYING
Keying of the transmitter can be toggled by clicking on the TX Key switch also in the lower-right corner.

OPERATING PTT
Push-to-talk can be toggled by clicking on the PTT switch in the lower-right corner. If this is on, PTT will be activated as long as there are characters in the send buffer.

SENDING TEXT FROM A FILE
To send text from a file press the Insert key and enter the file name (up to 8 characters in length). The file to be sent must have a .msg extension.

CODE PRACTICE MODE
Pressing Ctrl-P will start sending random callsigns for practice. Press Esc to stop.

BEACON MODE
Press Ctrl-B to start Beacon Mode. The contents of the F8 buffer will be sent repeatedly with a delay between repeats. A typical use would be to repeatedly call CQ. Default delay is 3 seconds.
Press Esc to exit Beacon Mode.
The delay between transmissions can be set through Setup, Beacon Delay.

AR = ; KN = ' AS = [ AA = ] SK = :

ESCAPE key is used to:
1) Dump the type-ahead buffer and clear screens; 2) Unkey the transmitter when keyed for tune-up (Ctrl-T); 3) Abort a file being sent.

Transmitter keying is done via the DTR lead on the serial port. PTT is on the RTS lead. These pins on serial ports are as follows:
DB-9 DB-25
DTR 4 20
RTS 7 4

This is a simple circuit you can use to key a solid state transmitter. I've used this circuit for some time on my Icom 756.

Many others can be found on the internet.
