D Convenient functions for transmit

• Break-in function (p. 6-3)
➥ Push [VOX/BK-IN] several times to select the
break-in OFF, semi break-in and full break-in.
• "BK IN" or "F-BK IN" appears when the semi break-in
or full break-in function is ON, respectively.

RECEIVE AND TRANSMIT
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.
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 operat-
ing frequency.
➥ Rotate [CW PITCH] to suit your preference.
• Adjustable within 300 to 900 Hz in 5 Hz steps.
✔ For your convenience
The filter set screen graphically displays the CW pitch
operations. (See at left.)
➥ Hold down [FILTER] for 1 second to access the fil-
ter set screen.
• The CW pitch frequency is graphically changed in 5 Hz
steps when the selected IF filter passband width is
below 500 Hz ("
the selected IF filter passband width is above 600 Hz
("
" disappears).
• Push [EXIT/SET] or hold down [FILTER] for 1 second to
return to the previous screen.
When the transceiver is in the receive condition (and
the break-in function is OFF— p. 6-3) you can listen to
the CW side tone without actually transmitting.
This allows you to match your transmit frequency ex-
actly 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. 12-5).
