. For full operating instructions, see the Full Manual. The Full Manual is available at the following internet address: https://www.icomjapan.com/support/

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 panel color display

• A built-in automatic antenna tuner

• Multi-function control for easy settings

PRECAUTIONS

R DANGER HIGH RF VOLTAGE! NEVER touch an antenna or antenna connector while transmitting. This could cause an electrical shock or burn.

R DANGER! NEVER operate the transceiver near unshielded electrical blasting caps or in an explosive atmosphere. This could cause an explosion and death.

R WARNING RF EXPOSURE! This device emits Radio Frequency (RF) energy. Extreme caution should be observed when operating this device. If you have any questions regarding RF exposure and safety standards please refer to the Federal Communications Commission

Ofce of Engineering and Technology’s report on

Evaluating Compliance with FCC Guidelines for Human

Radio Frequency Electromagnetic Fields (OET Bulletin 65).

R WARNING! NEVER operate the transceiver with a headset or other audio accessories at high volume levels. If you experience a ringing in your ears,reduce the volume or discontinue use.

R WARNING! NEVER apply AC power to the [DC13.8V] socket on the transceiver rear panel. This could cause a re

or damage the transceiver.

R WARNING! NEVER apply more than 16 V DC to the [DC13.8V] socket on the transceiver rear panel. This could cause a re or damage the transceiver.

R WARNING! NEVER reverse the DC power cable polarity. This could cause a re or damage the transceiver.

R WARNING! NEVER remove the fuse holder on the DC

power cable. Excessive current caused by a short could

cause a re or damage the transceiver.

R WARNING! NEVER let metal, wire or other objects contact the inside of the transceiver, or make incorrect contact with connectors on the rear panel. This could cause an electric shock or damage the transceiver.

R WARNING! NEVER operate or touch the transceiver with wet hands. This could cause an electric shock or damage to the transceiver.

R WARNING! Immediately turn OFF the transceiver power and remove the DC power cable from the transceiver if it

emits an abnormal odor, sound or smoke. Contact your Icom dealer or distributor for advice.

R WARNING! NEVER put the transceiver on an unstable place where the transceiver may suddenly move or fall. This could cause an injury or damage the transceiver.

R WARNING! NEVER operate the transceiver during a lightning storm. It may result in an electric shock, cause

a re or damage the transceiver. Always disconnect the

power source and antenna before a storm.

CAUTION: NEVER expose the transceiver to rain, snow or any liquids.

CAUTION: NEVER change the internal settings of the transceiver. This could reduce transceiver performance and/or damage to the transceiver. The transceiver warranty does not cover any problems caused by unauthorized internal adjustments.

CAUTION: NEVER install or place the transceiver in a place without adequate ventilation, or block any cooling vents on the top, rear, sides or bottom of the transceiver. Heat dissipation may be reduced and damage the transceiver.

CAUTION: NEVER use harsh solvents such as Benzine or alcohol when cleaning, as they will damage the transceiver surfaces.

CAUTION: NEVER leave the transceiver in areas with

temperatures below –10°C (+14°F) or above +60°C (+140°F) for mobile operations.

CAUTION: NEVER place the transceiver in excessively dusty environments. This could damage the transceiver.

DO NOT place the transceiver against walls or putting anything on top of the transceiver. This may overheat the transceiver.

BE CAREFUL! The Main unit will become hot when operating the transceiver continuously for long periods of time.

CAUTION: If you use a linear amplier, set the

transceiver’s RF output power to less than the linear

amplier’s maximum input level, otherwise a high input could damage the linear amplier.

CAUTION: Use only Icom supplied or optional

microphones. Other manufacturer’s microphones may have

different pin assignments, and could damage the connector and/or the transceiver.

NEVER place the transceiver in an insecure place to avoid inadvertent use by unauthorized persons.

Turn OFF the transceiver’s power and/or disconnect the AC

power cable when you will not use the transceiver for a long period of time.

Turn OFF the transceiver’s power and/or disconnect the DC

power cable when you will not use the transceiver for long period of time.

BASIC OPERATION

About the 5 MHz frequency band operation (USA version only)

Operation on the 5 MHz frequency band is allowed on 5 discrete frequencies and you must adhere to the following:

• The USB, USB Data, PSK, and CW modes.

• Maximum of 100 watts ERP (Effective Radiated

Power)

• Maximum 2.8 kHz bandwidth

It is your responsibility to set all controls so that transmission in this frequency band meets the stringent conditions under which amateur operations may use these frequencies.

TIP: We recommend that you save these frequencies, modes and lter settings into memory channels, for easy recall.

NOTE: To assist you in operating within the rules specied by the FCC, transmission is illegal on any frequencies other than the ve shown in the tables below.

For the USB and USB data modes:

The FCC species center frequencies on the 5 MHz frequency band. However, the transceiver displays carrier frequency. Therefore, tune the transceiver to 1.5 kHz below the specied FCC channel center frequency.

ANTENNA TUNER OPERATION

TUNER

About the internal antenna tuner

The internal automatic antenna tuner automatically matches the transceiver to the antenna within the

range of 16.7 ~ 150 Ω (SWR of less than 3:1).

After the tuner matches an antenna, the latching relay combinations are memorized as a preset point for

each frequency range (100 kHz steps). Therefore,

when you change the frequency range, the latching relay combinations are automatically preset to the memorized point for fast tuning.

• When you install a new antenna, or you want to change the antenna settings, you can clear the all of the internal antenna tuner preset points with the

“<<Preset Memory Clear>>” item on the TUNER set screen. (p. 8-3)

SET > Function > Tuner >

<<Preset Memory Clear>>

• You can select whether or not to save the internal antenna tuner’s status after pushing

band in the “[TUNER] Switch” item on the TUNER

set screen. (p. 8-9)

SET > Function > Tuner >

NOTE: When the transceiver receives a strong physical

shock, the internal latching relays may be returned to an

D Manual tuning

You can manually tune the antenna before transmitting.

1. Hold down tuning.

• The tuner reduces the SWR to less than 1.5:1 after

2~3 seconds of tuning.

L While tuning, “TUNE” blinks red.

2. After tuning, “TUNE” is displayed.

L If the tuner cannot reduce the SWR to less than 1.5:1

after 20 seconds, tuning stops and “TUNE” goes out.

D PTT Tuner start

The tuner is always activated when PTT is pushed

after the frequency is changed (more than 1% from last-tuned frequency). This function tunes the antenna for the rst transmission on a new frequency. L This function can be turned ON in the “PTT Start”

item of the TUNER set screen. (p. 8-3)

» SET > Function > Tuner > PTT Start

NOTE:

• If the SWR is higher than about 1.5:1 when tuning more than 100 kHz on an antenna’s preset point, hold down [TUNER] for 1 second to start manual tuning.

ANTENNA TUNER OPERATION

About an external antenna tuner

The optional AH-4 antenna tuner matches the IC-7300 to a long wire antenna more than 7 m/23 ft long (3.5 MHz and above). During mobile operation, the optional AH-2b antenna

element matches the IC-7300 to a whip antenna more

than 2.5 m/8.2 ft long (7 ~ 50 MHz). The optional AH-740 automatic tuning antenna covers 2.5 to 30 MHz range with a supplied whip

antenna.

R DANGER HIGH VOLTAGE! NEVER touch the antenna element while tuning or

transmitting. Always install it in a secure place.

NEVER operate the AH-4 or AH-740 without an antenna

connected. The tuner and transceiver will be damaged.

D Using the AH-4 or AH-740

1. Turn ON the transceiver.

L Each time you push

or goes out, and the AH-4 or AH-740 is turned ON or OFF (bypassed).

2. Hold down

for 1 second to start manual

tuning.

• The tuner reduces the SWR to less than 2:1 after 2~3 seconds of tuning.

L While tuning, “TUNE” blinks red. L If the tuner cannot reduce the SWR to less than 2:1

after 15 seconds of tuning, “TUNE” goes out.

3. After tuning, “TUNE” is displayed.

L When the long wire antenna cannot be tuned, “TUNE”

goes out. In that case, the AH-4 is bypassed and the

wire is directly connected.

NOTE: When the wire antenna cannot be tuned, conrm

wire length and connection.

Note that the AH-4 cannot tune a wire that is a ½λ long or

on a multiple of that frequency.

, “TUNE” is displayed

D Using an external antenna tuner

When you use a non-Icom external antenna tuner, be sure to turn OFF the internal antenna tuner before connecting the external antenna tuner.

Otherwise, the tuning may fail because both antenna

tuners (internal and external) will simultaneously start

tuning.

See the antenna tuner’s instruction manual for details.

NOTE: Be sure not to connect the antenna tuner without an antenna connected. This could damage the transceiver

or external antenna tuner.

TIP:

If the SWR is not reduced to 2:1 after retuning, see

“If the tuner cannot tune the antenna” on page 7-1 for details.

When the SEND terminal controls an inductive load, such as a relay, a counter-electromotive force can malfunction

or damage the transceiver. To prevent this, we recommend adding a switching diode, such as an 1SS133, on the load

side of the circuit to absorb the counter-electromotive force.

When the diode is added, a delay in relay switching may occur. Be sure to check its switching action before operating.

INSTALLATION NOTES

For amateur base station installations it is recommended that the forward clearance in front of the antenna array is calculated relative to the EIRP (Effective Isotropic Radiated Power). The clearance height below the antenna array can be determined in most cases from the RF power at the antenna input terminals.

As different exposure limits have been recommended for different frequencies, a relative table shows a guideline for installation considerations.

Below 30 MHz, the recommended limits are specied in terms of V/m or A/m elds as they are likely to fall within the near-eld region. Similarly, the antennas may be physically

short in terms of electrical length and that the installation will require some antenna matching device which can create

local, high intensity magnetic elds. Analysis of such MF

installations is best considered in association with published guidance notes such as the FCC OET Bulletin 65 Edition 97-01 and its annexes relative to amateur transmitter installations. The EC recommended limits are almost

identical to the FCC specied ‘uncontrolled’ limits and tables

exist that show pre-calculated safe distances for different antenna types for different frequency bands. Further information can be found at http://www.arrl.org/.

• Typical amateur radio installation

Exposure distance assumes that the predominant radiation pattern is forward and that radiation vertically downwards is at unity gain (sidelobe suppression is equal to main lobe gain). This is true of almost every gain antenna today. Exposed persons are assumed to be beneath the antenna array and have a typical height of 1.8 m.

The gures assume the worst case emission of a constant carrier.

For the bands 10 MHz and higher the following power density limits have been recommended:

10–50 MHz 2 W/sq m

Vertical clearance by EIRP output

1 Watts 2.1 m 10 Watts 2.8 m 25 Watts 3.4 m 100 Watts 5 m 1000 Watts 12 m

Forward clearance by EIRP output

100 Watts 2 m 1000 Watts 6.5 m 10,000 Watts 20 m 100,000 Watts 65 m

In all cases any possible risk depends on the transmitter

being activated for long periods. (actual recommendation

limits are specied as an average during 6 minutes)

Normally the transmitter is not active for long periods of time. Some radio licenses will require that a timer circuit automatically cuts the transmitter after 1–2 minutes etc.

Similarly some types of emission, i.e., SSB, CW, AM etc.

have a lower ‘average’ output power and the assessed risk

is even lower.

ZLIB DATA COMPRESSION LIBRARY

zlib 1.2.8 is a general purpose data compression library. All the code is thread safe. The data format used by the zlib library is described by RFCs (Request for

Comments) 1950 to 1952 in the les http://

tools.ietf.org/html/rfc1950 (zlib format),

rfc1951 (deate format) and rfc1952 (gzip

format).

All functions of the compression library are

documented in the le zlib.h (volunteer to

write man pages welcome, contact zlib@ gzip.org). A usage example of the library is

given in the le test/example.c which also

tests that the library is working correctly.

Another example is given in the le test/

minigzip.c. The compression library itself

is composed of all source les in the root

directory.

To compile all les and run the test program,

follow the instructions given at the top of

Makele.in. In short "./congure; make test",

and if that goes well, "make install" should

work for most avors of Unix. For Windows, use one of the special makeles in win32/ or

contrib/vstudio/ . For VMS, use make_vms. com.

Questions about zlib should be sent to <zlib@gzip.org>, or to Gilles Vollant <info@ winimage.com> for the Windows DLL version. The zlib home page is http://zlib. net/ . Before reporting a problem, please check this site to verify that you have the latest version of zlib; otherwise get the latest version and check whether the problem still exists or not.

PLEASE read the zlib FAQ http://zlib.net/ zlib_faq.html before asking for help.

Mark Nelson <markn@ieee.org> wrote an article about zlib for the Jan. 1997 issue of Dr. Dobb's Journal; a copy of the article is available at http://marknelson.us/1997/01/01/ zlib-engine/ .

The changes made in version 1.2.8 are

documented in the le ChangeLog.

Unsupported third party contributions are provided in directory contrib/ .

zlib is available in Java using the java.util.zip package, documented at http://java.sun.com/ developer/technicalArticles/Programming/ compression/ .

A Perl interface to zlib written by Paul Marquess <pmqs@cpan.org> is available at CPAN (Comprehensive Perl Archive Network) sites, including http://search.cpan. org/~pmqs/IO-Compress-Zlib/ .

A Python interface to zlib written by A.M. Kuchling <amk@amk.ca> is available in Python 1.5 and later versions, see http:// docs.python.org/library/zlib.html .

zlib is built into tcl: http://wiki.tcl.tk/4610 .

An experimental package to read and write

les in .zip format, written on top of zlib by

Gilles Vollant <info@winimage.com>, is available in the contrib/minizip directory of zlib.

Notes for some targets:

- For Windows DLL versions, please see win32/DLL_FAQ.txt

- For 64-bit Irix, deate.c must be compiled

without any optimization. With -O, one libpng test fails. The test works in 32 bit

mode (with the -n32 compiler ag). The

compiler bug has been reported to SGI.

- zlib doesn't work with gcc 2.6.3 on a DEC

III

3000/300LX under OSF/1 2.1 it works when compiled with cc.

- On Digital Unix 4.0D (formely OSF/1) on AlphaServer, the cc option -std1 is necessary to get gzprintf working correctly.

This is done by congure.

- zlib doesn't work on HP-UX 9.05 with some versions of /bin/cc. It works with other compilers. Use "make test" to check your compiler.

- gzdopen is not supported on RISCOS or BEOS.

- For PalmOs, see http://palmzlib. sourceforge.net/

Acknowledgments:

The deate format used by zlib was dened by Phil Katz. The deate and zlib specications were written by L. Peter

Deutsch. Thanks to all the people who reported problems and suggested various improvements in zlib; they are too numerous to cite here.
