4 RECEIVE AND TRANSMIT ■ Operating CW (Continued) D About the CW reverse mode The CW reverse mode receives signals with a reverse side CW carrier point similar to voice LSB and USB modes. Use when interfering signals are near a desired signal and you want to reduce the interfering tone. q Push [CW/RTTY] once or twice to select the CW mode. w Hold down [CW/RTTY] for 1 second to toggle between CW and CW-R mode, if necessary. • Check that the interfering tone can be reduced. D About CW pitch control The received CW audio pitch and CW sidetone can be adjusted to suit your preference without changing the operating frequency. ➥ Rotate [CW PITCH] to suit your preference. • Adjustable from 300 to 900 Hz (in 5 Hz steps) D About keying speed The transceiver's internal electronic keyer speed can be adjusted to between 6 and 48 wpm (words per minute). ➥ Rotate [KEY SPEED] clockwise to increase keying speed; counterclockwise to decrease it. D CW sidetone function When the transceiver is in the receive mode (and the Break-in function is OFF- p. 79), you can listen to the CW sidetone without actually transmitting. You can also use the CW sidetone to practice CW sending, but be sure to turn OFF the Break-in function. The CW sidetone level can be adjusted in the "Side Tone Level" item of the Keyer Set mode (p. 54).
