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 signal
and you want to use CW-R to reduce the interference.
➥ During CW mode, push
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 oper-
ating frequency.
➥ Rotate [CW PITCH] to suit your preference.
• Adjustable within 300 to 900 Hz in 5 Hz steps.
When the transceiver is in receive (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. 12-6).
Matching the frequency of a transmitted and re-
ceived signal is called "Zero beat."
