Measuring Swr; D Spot Measurement; D Plot Measurement - Icom IC-7000 Instruction Manual

The IC-7000 has a built-in circuit for measuring
antenna SWR—no external equipment or special
adjustments are necessary.
The IC-7000 can measure SWR in 2 ways—spot
measurement and plot measurement.
D
q Select CW or RTTY operation with [MODE].
w Confirm that the output power is over 30 W.
e Select S-1.
r Push [F-3 MET] one or more times to select the
SWR meter.
t 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.
-
SWR 1 1.5 2
The best match is in this range.
D
Plot measurement allows you to measure the SWR
over an entire band.
q Confirm that the output power is over 30 W.
w Set the center frequency for the SWR to be
measured.
e Select G-3 (SWR meter).
r Hold down [F-4
STEP
times to select the desired measuring step from
10, 50, 100 and 500 kHz.
t Push [F-2] or [F-3] one or more times to select
the desired number of measuring steps from 3, 5,
7, 9, 11, and 13 steps.
y Push [F-1] to start the measuring.
u Hold down [PTT] on the microphone to measure
the SWR.
∫," appears below SWR graph.
i When releasing [PTT], the frequency marker and
frequency indication move to the next frequency
to be measured.
o Repeat steps u and i to measure SWR over
the entire frequency range.
!0 When the measured SWR is less than 1.5:1, the
antenna is well matched with the transceiver in
the measured frequency range.

FUNCTIONS FOR TRANSMIT
The SWR can only be measured on [ANT1]
connector, in the HF/50 MHz bands when an
antenna is connected. However, when a 144/430
MHz antenna is connected to [ANT2], the SWR
cannot be measured.
[MENU/GRP] [F-3]
Push [F-1] to start
mesuring.
Push [F-2] or [F-3] to select number of
SWR mesuring steps.
(after pushing [F1])
Frequency marker appears and moves
after measurement.
The antenna is well matched in this range
