RECEIVE AND TRANSMIT
n Split frequency operation
Split frequency operation allows you to transmit and
receive on two different frequencies. Split frequency
operation uses two frequencies, one in VFO A and
the other in VFO B.
Following is an example of setting 7.057 MHz, CW
mode in VFO A (for receive) and 7.025 MHz, CW
mode in VFO B (for transmit).
q Select VFO B and set the frequency to 7.025
MHz/ CW.
w Push [A/B] to select VFO A and set the frequency
to 7.057 MHz/CW.
e Push [SPL] to turn the split frequency operation
ON.
• Split operation is now set for receive 7.057 MHz/CW
and transmit 7.025 MHz/CW.
• To change the receive frequency, rotate the main dial,
to change the transmit frequency, rotate the main dial
during transmit mode.
To exchange the transmit and receive frequencies,
push [A/B].
n SWR
The IC-718 has a built-in circuit of measuring antenna
SWR—no external equipment or special adjustments
are necessary.
ï Measuring SWR
q Confirm that the output power is over 30 W.
w Push [SET] one or more times to select the SWR
meter.
e Push [MODE] one or more times to select CW or
RTTY operation.
• Key down or push [PTT] to transmit; then read
the actual SWR from the meter:
≤ 1.5 well matched antenna
≥ 1.5 check antenna or cable connection, etc.
The best match is in this range.
