SAVE THIS INSTRUCTION MANUAL This instruction manual contains full operating instructions for the 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 magnified. 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.

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) MENU SET > Function > Tuner >

<<Preset Memory Clear>>

You can select whether or not to save the internal antenna tuners status after pushing TUNER on each band in the [TUNER] Switch item on the TUNER set screen. (p. 8-3) MENU SET > Function > Tuner >

[TUNER] Switch NOTE: When the transceiver receives a strong physical shock, the internal latching relays may be returned to an unlatched condition. In that case, push TUNER to turn OFF the tuner, then turn ON again to reset the all latching relays. 7-1 Internal antenna tuner operation 1. Push TUNER to turn ON the internal antenna tuner. TUNE is displayed when the tuner is ON. Tune the antenna. L To tune the antenna, see Manual tuning or PTT 2. Tuner start below. DManual tuning You can manually tune the antenna before transmitting for the first time. 1. Hold down TUNER for 1 second to start manual tuning. The tuner reduces the SWR to less than 1.5:1 after 2~3 seconds of tuning. L While tuning, a side tone is heard and 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. DPTT 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 first 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) MENU SET > Function > Tuner > PTT Start NOTE:

If the SWR is higher than about 1.5:1 when tuning more than 100 kHz on an antennas preset point, hold down

[TUNER] for 1 second to start manual tuning. If you transmit into a high SWR, TUNE may blink. In that case, hold down TUNER for 1 second to manually tune. If the tuner cannot tune the antenna Repeat manual tuning several times. Even if the tuner cannot tune the antenna on the first tuning, it may success at the second tuning. Some antennas, especially for the low bands, have a narrow bandwidth. These antennas may not tune at the edge of their bandwidth, therefore, tune such an antenna as follows:

(Example):

Suppose you have an antenna which has an SWR of 1.5:1 at 3.55 MHz and an SWR of 3:1 at 3.8 MHz. 1. Set 3.55 MHz, and hold down TUNER for 1 second to start manual tuning. 2. Set 3.80 MHz, and hold down TUNER for 1 second to start manual tuning. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 8 SET MODE Set mode description You can use the Set mode to set infrequently changed values or function settings.

*1 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.

The clearance height below the antenna array can be determined in most cases from the RF power at the antenna input terminals. In all cases any possible risk depends on the transmitter being activated for long periods. (actual recommendation limits are specified 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 12 minutes etc. As different exposure limits have been recommended for different frequencies, a relative table shows a guideline for installation considerations. Similarly some types of emission, i.e., SSB, CW, AM etc. have a lower average output power and the assessed risk is even lower. List of Country codes (ISO 3166-1) Country Codes Codes 1 Austria 2 Belgium 3 Bulgaria 4 Croatia 5 Czech Republic 6 Cyprus 7 Denmark 8 Estonia 9 Finland 10 France 11 Germany 12 Greece 13 Hungary 14 Iceland 15 Ireland 16 Italy 17 Latvia Country 18 Liechtenstein 19 Lithuania LI LT LU MT 21 Malta NL 22 Netherlands NO 23 Norway PL 24 Poland PT 25 Portugal RO 26 Romania SK 27 Slovakia SI 28 Slovenia ES 29 Spain SE 30 Sweden CH 31 Switzerland 32 Turkey TR 33 United Kingdom GB AT BE BG 20 Luxembourg HR CZ CY DK EE FI FR DE GR HU IS IE IT LV Below 30 MHz, the recommended limits are specified in terms of V/m or A/m fields as they are likely to fall within the near-field 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 fields. 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 specified 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 figures assume the worst case emission of a constant carrier. For the bands 10 MHz and higher the following power density limits have been recommended:

Phone : +81 6 6793 8424 Fax: +81 6 6793 3336 e-mail: world_support@icom.co.jp URL : http:/Awww.icom.co.jp/world Date: February 5, 2016 To Whom It May Concern Subject: Scanning Receiver Statement Applicant: Icom Incorporated Product: Scanning Receiver Model: IC-7300 FCC ID: AFJ376500 The equipment under application herein incorporates a scanning receiver. Accordingly, 15.121 of the Commission's rules applies. The equipment under application herein is incapable of operating (tuning), or being readily altered by the user to operate within the frequency bands allocated to the Domestic Public cellular Radio Telecommunications Service (Cellular Radio Service). The equipment is also incapable of converting digital cellular transmissions to analog voice audio. The receiver portion of the equipment under application herein scans 0.03-74.800MHz, the receiver does not scan the bands used by the Cellular Radio Service, 824-849 and 869-894MHz. The receiver portion of the equipment under application cannot be altered to enable it to scan the Cellular Radio Service bands by means of clipping the leads of or installing a diode, resistor and/or jumper wire, or other such simple component. Nor can the receiver be made to scan the Cellular Radio Service bans by replacing a plug-in semiconductor chip, since no such plug-in chips are utilized. The semiconductor chips that are utilized in the equipment cannot be erased and reprogrammed. The radio design of the tuning, control and filtering circuitry on the receiver is controlled by the serial data from the firmware code in the microprocessor, which is built-in by the microprocessor manufacture as a part of the internal design of the processor. Since the processor information is inaccessible to the user (Even Icom peoples), if someone attempt modifying circuitry without the knowledge of the firmware code, the radio simply will fail to operate. In view of the above, the equipment complies with 15.121 of the Commission rules. Sincerely Icom Incorporated Hideji Fujishima AL General Manager of Quality Assurance Department
