bh SET MODE
(5) RTTY keying polarity "rtty-P"
You can select normal or reverse polarity for RTTY
keying.
When the reverse polarity is selected, Mark and
Space are reversed.
- Normal : Key open/close = Mark/Space
- Reverse : Key open/close = Space/Mark
(6) CW pitch setting DICH 7
The CW pitch can be set within 300-900 Hz in 20 Hz
steps in P-set mode.
- Check the pitch with key down in CW mode. (p. 29)
Y For your convenience, the CW pitch can be
adjusted with the [SQL] control after changing the
[SQL] control function in P-set mode. In this
case, this item does not dE See item (8)
below for details. )
(7) Calibration marker "CAL"
Calibration marker is used for a simple frequency

control ("PItCH"), if desired. In this case, the
squelch continuously opens (max. counterclockwise
position) and the CW pitch setting of the P-set mode
(item 6 above) does not appear.
[SQL] adjusts the squelch threshold level. (default)

e [NB WIDE] switch function "SELECt2" 7
The [NB WIDE] switch can be assigned to noise
reduction on/off switch ("nr"), if desired. This item
does not appear when the DSP unit is not installed
