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.
q Push [POWER] to turn the linear amplifier ON
then turn the exciter’s power ON.
w Select the input/output antenna with [INPUT] and
[ANT].
e Set the exciter to CW or RTTY mode with mini-
mum output power.
r Select the temperature and SWR meters with
[METER-1] and [METER-2].
- The [TEMP] and [SWR] indicators light.
t Push [TUNER] and [AMP/PROTECT] to turn the
automatic antenna tuner and linear amplifier cir-
cuit ON.
y Push [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.
u Use 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.
i Transmit 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.
o The 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.
D Band 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.
