Functions for CW operation

D About CW reverse mode

CW-R (CW Reverse) mode uses the opposite side

band to receive CW signals.

Use when interfering signals are near a desired sig-

nal and you want to use CW-R to reduce the interfer-

ence.

During CW mode, push [CW] to select CW and

CW-R mode.

D About CW pitch control

The received CW audio pitch and CW side tone

can be adjusted to suit your preference (from 300

to 900 Hz in 5 Hz steps). This does not change the

operating frequency.

Rotate [CW PITCH] to suit your preference.

• Adjustable within 300 to 900 Hz in 5 Hz steps.

The filter set screen graphically displays the CW

pitch operations. (See at right.)

D CW side tone function

When the transceiver is in receive (and the break-in

function is OFF— p. ??) you can listen to the CW side

tone without actually transmitting.

This allows you to match your transmit frequency

exactly to another station's by matching the audio

tone. You can also use the CW side tone (be sure to

turn OFF break-in!) to practice CW sending.

CW side tone level can be adjusted in level set mode

(p. ??).

q Push [SET] (F-6), then push [LEVEL] (F-1) to

select level set mode.

w Push [Y] (F-1) or [Z] (F-2) to select "Side Tone

Level" item.

e Rotate the main dial to adjust the side tone level.

• Side tone level is adjustable within 0 to 100 % in 1%

steps.

r Push [EXIT/SET] to exit display set mode.

Matching the frequency of a transmitted and

received signal is called "Zero beat."
