4 RECEIVE AND TRANSMIT 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. D About CW reverse mode Push BFO Interference Desired signal CW mode (LSB side) BFO Interference Desired signal CW-R mode (USB side) D About CW pitch control [CW PITCH] CW-R (CW Reverse) mode uses the opposite side band to receive CW signals. Use when interfering signals are near a desired signal and you want to use CW-R to reduce the interference. ➥ 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 operating frequency. ➥ Rotate [CW PITCH] to suit your preference. • Adjustable within 300 to 900 Hz in 25 Hz steps. D CW side tone function [MONI GAIN] 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 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. 12-5). 4-5

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 signal
and you want to use CW-R to reduce the interference.
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 oper-
ating frequency.
Rotate [CW PITCH] to suit your preference.
• Adjustable within 300 to 900 Hz in 25 Hz steps.
D
CW side tone function
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).

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.
