CONNECTING THE AH-4
CONNECTING THE AT-180
• Turn the IC-7000’s power OFF when connecting
the AT-180, otherwise, the CPU may malfunction
and the AT-180 may not function properly.
• The OPC-742 is required when using both the AT-
180 and a 2m/70cm linear amplifier.
• Do not connect [ANT2] to the AT-180. When using
an HF to 2m/70cm dual or wide-band antenna,
use a duplexer between the AT-180 and antenna
since 2 m/70 cm signals do not pass through the
AT-180.
