Icom AG-2400 [2/4] I connections
■ 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 eleva-
tion angle rotator which adjusts the angle above the hori-
zon, 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, be-
cause 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 protec-
tor may not function correctly when accidental trans-
mission such as continuous transmission is applied.
ï Before setting
Test to operate on the ground before installation is rec-
ommended.
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 an-
gles, 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 ap-
propriate satellite tracking software. In the wrong
mode, you cannot use the satellite even if you re-
ceive its beacon signal.

• Use the U-bolts
• 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 valcan-
izing tape to avoid water seeping into the unit. Bind-
ing the type-N connector with self valcanizing tape
increases the waterproofing of the connection mold.
