TRACe ON | OFF Default: OFF
Mode: packet/Baudot/AMTOR/PACTOR Host: TR
OFF
Trace function is disabled.
ON Trace function is activated.
Packet :
TRACE
activates the AX.25 protocol display. With
TRACE ON
, all received frames are displayed in their
entirety, including all header information. The TRACE display is shown as it appears on an 80-column display. The
following monitored frame is a sample:
KB6IUX*>TESTER <UI>:
This is a test message packet.
Byte Hex Shifted ASCII ASCII
000: A88AA6A8 8AA460AE 6494AAA0 406103F0 TESTER0KB6IUX0.x ......`.d...@a..

020: 65737361 67652070 61636B65 742E0D 299032.80152:.. essage packet...
The byte column shows the offset into the packet of the first byte of the line. The hex display column shows the
next 16 bytes of the packet, exactly as received, in standard hex format. The Shifted ASCII column decodes the
high-order seven bits of each byte as an ASCII character code. The ASCII column decodes the low-order seven bits
of each byte as an ASCII character code.
Interspersed command prompts and even the L and R commands would have no effect on the final data, and it could
be translated back to binary data with a computer program.
TXRev ON | 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.
WIdeshft ON

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.
