Split Frequency Operation; Swr - Icom ic-718 Instruction Manual

5
RECEIVE AND TRANSMIT
 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.
The 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 ON the split frequency opera-
tion.
• 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
in the transmit mode.
To exchange the transmit and receive frequencies,
push [A/B].
 SWR
The IC-718 has a built-in circuit to measure antenna
SWR— no external equipment or special adjustments
are necessary.
ï Measuring SWR
q Confi rm 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 the CW
or RTTY operation.
• Key down or push [PTT] to transmit, then read the ac-
tual SWR from the meter:
 1.5 well matched antenna
 1.5 check antenna or cable connection and so on.
26
The best match is in this range.
