your IC-7300.
FEATURES
•RF Direct Sampling System
The IC-7300 employs an RF direct sampling system.
RF signals are directly converted to digital data and
processed in the FPGA. This system is a leading
technology marking an epoch in amateur radio.
•Real-Time Spectrum Scope
The spectrum scope is class-leading in resolution,
sweep speed and dynamic range. When you touch the
scope screen on the intended signal, the touched area is
magnied. The large 4.3 inch color TFT touch LCD offers
intuitive operation.
•New “IP+” Function
The new IP Plus function improves 3rd order intercept
point (IP3) performance. When a weak signal is received
adjacent to strong interference, the AD converter is
optimized against signal distortion.
•Class Leading RMDR and Phase Noise
Characteristics
The RMDR is improved to about 97dB (typical value) and
Phase Noise characteristics are also improved about
15dB (at 1 kHz frequency separation) compared to the
IC-7200.
•A 4.3 inch touch screen color display
•A built-in automatic antenna tuner
•Multi-function control for easy settings

Selecting a location
Select a location for the transceiver that allows
adequate air circulation, free from extreme heat, cold
or vibrations, and other electromagnetic sources.
The transceiver has a stand for desktop use.
Stand
CAUTION: NEVER carry the transceiver by holding the
stand, dials, controls and so on. This may damage them.
Heat dissipation
Grounding
To prevent electrical shock, television
interference (TVI), broadcast
interference (BCI) and other
problems, ground the transceiver
using the ground terminal [GND] on
the rear panel.
For best results, connect a heavy
gauge wire or strap to a long ground
rod. Make the distance between the
[GND] terminal and ground as short
as possible.
RWARNING! NEVER connect the [GND] terminal
to a gas or electric pipe, since the connection could
cause an explosion or electric shock.

Using an External Keypad
You can control the CW memory keyer, Voice memory or
RTTY memory keyer transmission from an external keypad by
connecting the control circuit to the [MIC] connector. Set the
“External Keypad” to ON on the CONNECTORS screen to use
the external keypad. (p. 12-8)
Accepts headphones with 8~16 Ω
impedance.
• Outputs 5 mW into an 8 Ω load.
• The volume level may differ,
depending on the headphones.
[PHONES] Headphones
• DO NOT place the transceiver against walls or put
anything on top of the transceiver. This may block
airow and overheat the transceiver.
• NEVER install the transceiver in a place without
adequate ventilation. Heat dissipation may be
reduced, and the transceiver may be damaged.
• DO NOT touch the transceiver after transmitting
continuously for long periods of time. The transceiver
may become hot.
