CAUTION FOR INSTALLATION
AG-2400 is intended for professional installation only .
We are not responsible for any building breakage, any
damage resulting from a drop of the AG-2400 from a
high place or unstable site resulting in personal injury ,
nor any accident in any other cases. If the AG-2400
must be installed at such high place or unstable site,
be sure to consult an expert engineer.

INSTRUCTION MANUAL
■ Connections
Satellite communications via the AO-40 can be made
when using the IC-910H satellite function mode and
the AG-2400.
For satellite communications, an antenna rotator which
adjusts the antenna direction (azimuth), and an elevation angle rotator which adjusts the angle above the horizon, are necessary .
See back page on how to operate.
ï Converting frequency with the AG-2400
• 2400.225–2400.475 MHz to 144.225–144.475 MHz
• 2401.210–2401.495 MHz to 145.210–145.495 MHz
NOTE: Turn the pre-amplifier controller for 144 MHz
ON during satellite operation with the AG-2400, because the external pre-amplifier control voltage is
used as the AG-2400’s main power.
CAUTION! NEVER transmit on the 144 MHz band.
The AG-2400 may be damaged. The built-in protector may not function correctly when accidental transmission such as continuous transmission is applied.
ï Before setting
Test to operate on the ground before installation is recommended.
q Connect AG-2400 and IC-910H. (See the figure at
left.)
w Turn the IC-910H power ON.
• Push [M/S] to set the 144 MHz as in the MAIN band.
e Push [SSB/CW] to select SSB or CW mode.
r Push [ATT•P.AMP] for 1 sec. to turn the AG-2400
power ON.
• When the AG-2400 functions correctly, the noise level
rise up.
ï Orbit information
Orbit information describes satellite location, wave angles, etc. This information may be available in ham
magazines or organization issues, such as from ARRL
or RSGB handbook, etc.
Use of satellite tracking software is also convenient.
ï AO-40
• Uplink frequency : 435.780–435.495 MHz
• Downlink frequency: 2400.225–2400.475 MHz (S1 BAND)
• Downlink frequency: 2401.210–2401.495 MHz (S2 BAND)
• Beacon frequency : 2400.338 MHz (S1 BAND)
2401.323 MHz (S2 BAND)
Confirm a satellite’s operating mode in advance
through documentation (magazines, etc.) or via appropriate satellite tracking software. In the wrong
mode, you cannot use the satellite even if you receive its beacon signal.

• Use the nuts • About waterproofing
The AG-2400 can also be installed with self-tapping
screws.
Tighten the U-bolts, Wing nuts, etc. about 2 weeks
after initial installation.
NOTE: Cover the type-N connector with self valcanizing tape to avoid water seeping into the unit. Binding the type-N connector with self valcanizing tape
increases the waterproofing of the connection mold.

■ Tracking selection
Push [F-INP ENT ] for 1 sec. to switch between normal and reverse tracking.
ï Normal tracking
Both downlink and uplink frequencies increase or decrease in the same step simultaneously by tuning dial
rotation.
ï Reverse tracking
The downlink frequency follows the tuning dial rotation,
however, the uplink frequency changes in the reverse
direction to the tuning dial rotation in the same step.
■ Preparation
q Decide on a usable satellite.
w Confirm the approximate location of the satellite and
operating mode (e.g. “B,” “J,” etc.) through documentation (magazine, etc.) or via appropriate satellite tracking software.
e Set the antenna direction for the desired satellite.
r Select satellite mode on the transceiver.
• Push [SATELLITE].
• Push [F-INP ENT ] for 1 sec. to select track-
ing mode if desired.
t Select operating mode.
y Set the downlink frequency (MAIN band) to the bea-
con frequency.
• Refer to a ham magazine or book for detailed information.
• Adjust the antenna direction so that the S-meter shows
to its strongest level.
• The S-meter level should be noted for transmit power adjustment during a loop test.

u Perform a loop test.
• Set the downlink frequency (MAIN band) to a vacant frequency within the satellite’s coverage.
• Push [SWP 0 S ] then, set the uplink frequency (SUB
band) while transmitting a single tone such as a whistle
to find your downlink signal and monitor your own signal
correctly. Push [SWP0 S ] after setting.
NOTE: To avoid excessive power, set the output
power so that the downlink signal strength is lower
than the beacon’s strength.
i Set the desired frequency to begin your satellite
communications.
• Both the downlink and uplink frequencies are changed
simultaneously.
o When your downlink audio drifts (Doppler effect),
push [SWP 0 S ] then rotate the tuning dial to adjust
the uplink frequency (SUB band) only.
Push [SWP 0 S ] again after setting.
• When a particular station’s audio is off frequency, use the
RIT function (push [RIT])
!0 To exit the satellite operation, push [SATELLITE].
CONVENIENT: As the transceiver has 10 satellite
memory channels, once set, desired satellite frequencies can be recalled instantly.
NOTE: As the downlink (MAIN band) signal is applied to the SUB band unit receiver circuit in satellite mode, an optional FL-133
CW NARROW FILTER
is
necessary to operate CW-N mode.
■ Satellite operation
When your own signal can be received with a loop test,
satellite communication can be performed.
q Rotate the tuning dial to re-tune the uplink frequency
after pushing [SWP 0 S ], when shifting a frequency
with the Doppler effect.
• The downlink frequency readout (MAIN band) disappears.
