PITCH
The CW Pitch adjustment feature controls several aspects of transceiver CW operation
simultaneously:
o
It
controls the pitch of the CW Sidetone;
o
It
controls the pitch of your transmitted signal (it is the same pitch as the Sidetone);
o
It
controls the center frequency ofthe IF passband, used by the IF filters; and
o
It controls the center frequency of the DSP CW Peaking Filter.
The CW Pitch is set to a default value of 700 Hz at the factory. To change the CW Pitch:
I. Press and hold in the [FUNC] key for
~
second to activate the MENU mode.
2. Rotate the SELECT knob to select Menu #50 (CW PITCH).
3.
Rotate the
MAIN DIAL
to choose the desired CW Pitch. The available settings are 4001
500/6001700/800 Hz.
4 When you have made your selection, press the [FUNC] key momentarily to save the
new setting and exit to normal operation.

If
you set the CW Pitch to a lower value (like 400 Hz),
it
is slightly easier to
'"
~"
"separate" signals in a crowded band, as each synthesizer step is larger (in
~
- percentage) at a lower audio frequency.
CW-REVERSE MODE
The default injection mode for CW operation is USB. How-
ever, in certain operating situations, you may wish to use the
"reverse" sideband, LSB. For example, when operating on 40
meters and lower HF bands, LSB is the mode used for SSB
voice communications, and if you wish to change modes to
CW, tuning is easier if the same sideband is used. Difficult in-
terference situations may sometimes be solved instantly by us-
ing the opposite sideband for reception.
From the CW mode, press and hold in the
[MODE]
key for Z2
second to toggle to the "CW-R" (Reverse) mode. You may re-
peat this process to toggle back to "Normal" (USB-side) op-
eration.
