The internal antenna tuner has an automatic start
capability which starts tuning if the SWR is higher
than 1.5–3:1.
• OFF : The tuner remains OFF even when the SWR
is poor (1.5–3:1). (default)
• ON : Automatic tune starts even when the tuner is
turned OFF during HF bands operation.
Tuner (PTT Start)
OFF
Tuning of the internal antenna tuner can be started
automatically at the moment the PTT is pushed after
the operating frequency is changed (more than 1%

to [ACC2] pin 6.
Transverter Offset
16.000MHz (14.000.00 30.000.00)
Sets the desired offset frequency for the transverter
operation within 0.000 to 99.999 MHz in 1 kHz steps.
(default: 16.000 MHz)
RTTY Mark Frequency
2125
Selects the RTTY mark frequency. RTTY mark fre-
quency is switched between 1275, 1615 and 2125
Hz. (default: 2125 Hz)
2125 Hz is automatically selected when the internal
RTTY decoder is used.
RTTY Shift Width
170
Selects the RTTY shift width. There are 3 selectable
values: 170, 200 and 425 Hz. (default: 170 Hz)
170 Hz is automatically selected when the internal
RTTY decoder is used.
RTTY Keying Polarity
Normal
Selects the RTTY keying polarity. Normal or reverse
keying polarity can be selected. (default: Normal)
When reverse polarity is selected, Mark and Space
are reversed.
• Normal : Key open/close = Mark/Space
• Reverse : Key open/close = Space/Mark
PSK Tone Frequency
1500
Selects the desired PSK tone frequency for the PSK
reception from 1000, 1500 and 2000 Hz.
(default: 1500 Hz)
SPEECH Language
English
Selects the speech language from English and Jap-
