Chapter 8 ASCII and Baudot Operation
TXRev

OFF
Default: OFF
Mode: Baudot/ASCII/AMTOR
Host: TX
OFF
Transmit data polarity is normal.
ON
Transmit data polarity is reversed (mark-space reversal).
Use
TXREV
to reverse the mark and space polarities in your transmitted AFSK and FSK signals.
In some cases, the station you’re working may be receiving inverted data although it’s transmitting in the correct
polarity. Set
TXREV
ON
to reverse the “sense” of your transmitted signals.
TXREV
only works on
ABAUD
and
RBAUD
at speeds up to 150 baud.
USOs

Default: OFF
Mode: Baudot RTTY
Host: US
OFF
Letters (LTRS) isn’t forced after receiving a space character.
ON
Letters (LTRS) case
is
forced after receiving a space character.
Use
USOS
(UnShift On Space) when you want your DSP to automatically change from FIGURES to LETTERS
after receiving a space character.
When using Baudot RTTY in poor HF receiving conditions, a received character can be incorrectly interpreted as a
FIGURES-SHIFT character, forcing the received data into the wrong case. Many otherwise good characters
received after this will be interpreted as figures (numbers and punctuation), not as the letters sent by the distant
station.
USOS
ON
helps reduce these receiving errors.
WIdeshft

OFF
Default: OFF
Mode: Baudot/ASCII, RTTY, AMTOR, PACTOR
Host: WI
OFF
RTTY tones are shifted 200 Hz (emulates 170-Hz shift).
ON
RTTY tones are shifted 1000 Hz.
WIDESHFT
permits the use of the DSP on VHF or HF with either wide (1000 Hz) or narrow (200 Hz) shifts. Many
amateur radio VHF and HF RTTY operators use 170-shift. The DSPs 200 Hz shift is well within the filter
tolerances of any RTTY demodulator in general service. MARS stations will find
WIDESHFT
generally
compatible with MARS and Commercial 850 Hz shift RTTY operations.
WOrdout
ON

OFF
Default: OFF
Mode: Baudot, ASCII, AMTOR, PACTOR and Morse
Host: WO
OFF
Inputted characters are sent directly to the transmitter.
ON
Inputted characters are held in the transmit buffer until a space, (
RETURN
),
LF
,
(
TAB
),
RECEIVE
,
CWID
,
ENQ
or
+
?
character(s) is typed.
Use
WORDOUT
to choose whether or not you can edit while entering text for transmission.
With
WORDOUT
ON
, each character you type is held in a buffer until you enter a space,
(
RETURN
),
LF
, ENQ
character ($05 [
CTRL-E]
) or the
+?
. You can edit or delete words before the transmit buffer’s contents are sent to
the radio as long as you haven’t entered pressed (
SPACE
),
(
RETURN
)
,
LF
, etc.
