Icom iPW1, iPW1EURO

OPERATION

CAUTION:

DO NOT operate the IC-PW1/EURO before

adjusting the ALC levels properly with the [ALC

adj1] and [ALC adj2] pots. (p. 11)

It takes 15 sec. for CI-V line initial settings when

several CI-V devices (more than 5) are connected

to a CI-V line.

For IC-781 users with other Icom CI-V transceivers:

Turn the IC-781 power ON before turning the IC-

PW1/EURO and other transceiver power ON and

keep the IC-781 power ON during operation.

qPush [POWER] to turn the linear ampliﬁer ON

then turn the exciter’s power ON.

wSelect the input/output antenna with [INPUT] and

[ANT].

eSet the exciter to CW or RTTY mode with mini-

mum output power.

rSelect the temperature and SWR meters with

[METER-1] and [METER-2].

- The [TEMP] and [SWR] indicators light.

tPush [TUNER] and [AMP/PROTECT] to turn the

automatic antenna tuner and linear ampliﬁer cir-

cuit ON.

yPush [UP]/[DOWN] to select [AUTO] for automat-

ic band selection when a CI-V Icom exciter is

used; or push [UP]/[DOWN] to select the desired

band for manual band selection.

uUse the exciter’s antenna tuner to tune the line

between the IC-PW1/EURO and exciter, if you

have an antenna tuner connected to the exciter.

iTransmit with the exciter and adjust the exciter’s

output power to 50 W with the RF output power

control on the exciter.

- [TRANSMIT] indicator lights.

- See the exciter’s instruction manual for transmitting.

oThe built-in antenna tuner automatically tunes the

antenna.

- SWR reading on meter-2 should be less than 1.2:1.

- Push [TUNER] for 2 sec. to tune the antenna manual-

ly.

- The [TUNER] indicator blinks while tuning.

- The [TUNER] indicator lights while the tuner is activat-

ed.

NOTE: The band information is not updated while

scanning. Turn the antenna tuner OFF and use the

manual band selection while scanning.

During split operation:

When changing the frequency more than 100 kHz,

the IC-PW1/EURO’s antenna tuner presets the

tuner to the new frequency. Use manual tuning

during split operation.

!0 When operating for long periods, select the tem-

perature meter with [METER-1] to monitor the lin-

ear ampliﬁer’s temperature.

- If the temperature meter reading is in the red “HOT”

zone, the exciter should be returned to receive, other-

wise, the protection circuit may be activated and the

linear ampliﬁer may be turned OFF.

DBand memory

The IC-PW1/EURO stores ON/OFF settings for the

antenna tuner and linear ampliﬁer according to the

operating band when at least 1 Icom exciter is con-

nected to the [INPUT1] connector.

The set conditions may not be stored when the lin-

ear ampliﬁer is turned OFF immediately after set-

ting the antenna tuner and linear ampliﬁer.
