PK-232 MBX Operating Manual - N3UJJ

The following parameters are the most common settings for HF ASCII
operation. Check the parameters and make sure they are set as follows:
ABAUD 110 (or whatever speed you wish)
RXREV OFF
TXREV OFF
WIDESHFT OFF
Some VHF Bulletin Boards and MSOs use ASCII at 110 and 300 bauds, most
commonly on two meters.
6.6.2 ASCII RTTY Operating Tips
Follow the general operating procedures shown in the sections above
for Baudot RTTY. As in Baudot operation, you can step the system
through all the available receiving speeds.
The following "Function Keys" and immediate commands are included for
ASCII RTTY operating convenience.
Immediate Commands From the Command Mode:
"R"
"X"
"K"
Switches system to receive mode.
Switches system to transmit mode and forces immediate
entry into Converse mode.
Load Transmit type ahead buffer.
"Function Key" characters embedded in transmitted text:
Sends AAB string as a HEREIS message.
Shuts off transmitter after sending character buffer.
Sends "Who Are You" request to distant station.
Sends call sign in Morse and shuts off the transmitter.
Sends the Time if the DAYTIME clock has been set.
6.6.3 Changing ASCII Baud Rates
Assume you've been receiving at 110 bauds and wish to increase the
baud rate in steps. From the Command mode, type AB U followed by an
. The PK-232 responds with:
ABaud was 45
ABaud now 50
The ABAUD command sets the ASCII RTTY speed. The most common speed
is 110 bauds on HF, but other speeds including commercial speeds are
supported. See the Command Summary for all the supported speeds.
6.6.4 Other RTTY Commands for ASCII Operation
Many of the commands mentioned above in the Baudot Section also
operate in the ASCII RTTY mode as well. They are listed below:
AAB ACRDISP ALFDISP DIDDLE EAS RXREV
TXREV WIDESHFT WORDOUT WRU
4/91 6-8
