and ASCII RTTY and AMTOR transmission. The polarity of the received data is not af-
fected. Use this option if you can't transmit with the opposite sideband to match a sta-
tion that is receiving inverted data.
3.4.1.3
Return to Receive Mode <CTRL-D>
In the Baudot and ASCII RTTY modes, you can insert the RECEIVE command <CTRL-
D> as you type "live" into the PK-232's transmit buffer, or you can write <CTRL-D> in a
pre-typed message stored on disk or tape. As soon as your PK-232 reads this com-
mand, it immediately shuts off your rig and returns you to the Command Mode.

Send Time and Day <CTRL-T>
In the Baudot/ASCII RTTY, AMTOR and Morse modes, use the character specified by
the TIME command (default <CTRL-T>) to insert the time of day in the text you type
into the transmit buffer, or into a text file stored on disk.
The PK-232 reads the control code and sends the time to your radio in the data trans-
mission code in use at that time, in format HH:MM, where "HH" is the hour in the 24-
hour system and "MM" is the minute. The "colon" is transmitted in all codes, including
Morse.

CW Identifier <CTRL-F>
In the Baudot and ASCII RTTY modes, you can insert the character specified by the
CWID command (default <CTRL-F>) as you type "live" into the PK-232's transmit buf-
fer, or you can write <CTRL-F> in a pre-typed message stored on disk or tape. When
your PK-232 reads <CTRL-F>, it switches to the Morse Mode, sends your previously
stored call sign in Morse code prefixed by "DE", turns off your transmitter and returns
to Command Mode.

In the U.S.A., the requirement for identifying your station in Morse code has
been eliminated. U.S. amateurs may now identify in whatever mode they are
operating. Check local government requirements.
