TABLE OF CONTENTS

OPERATING THEORY

Electromagnetic radiation which has frequencies of 20,000 Hz (20 kHz*) and above is called radio frequency (RF) energy because it is useful in radio transmissions. The IC-R10 receives RF energy from 0.5 MHz to 1300 MHz* and converts it into audio frequency (AF) energy which in turn actuates a loudspeaker to create sound waves. AF energy is in the range of 20 to 20,000 Hz.

*kHz is an abbreviation of kilohertz or 1000 hertz, MHz is abbreviation

of megahertz or 1,000,000 hertz, where hertz is a unit of frequency.

Ni-Cd BATTERIES AND ACCESSORIES

■ Charging Ni-Cd batteries

The supplied Ni-Cd batteries are rechargeable and can be charged approx. 300 times. Charge the batteries before ﬁrst operating the receiver or when the batteries become exhausted.

If you want to be able to charge the batteries more than 300 times, the following points should be observed:

1. Avoid overcharging. The charging period should be less than 48 hours.

2. Use the batteries until they become almost completely exhausted under normal conditions. We recommend battery charging just after receiving becomes impossible.

■ Charging precautions

NEVER attempt to charge dry cell batteries. This will cause

internal liquid leakage and damage the receiver.

NEVER connect two or more chargers at the same time.

Charging may not occur under temperatures of 10°C (50°F) or over temperatures of 40°C (104°F).

■ About Ni-Cd batteries

Ni-Cd battery life

If your Ni-Cd batteries seems to have no capacity even after being fully charged, completely discharge them by leaving the power ON overnight. Then, fully charge the Ni-Cd batteries again. If the Ni-Cd batteries still do not retain a charge (or very little), new batteries must be purchased.

Recycling information (U.S.A. only)

The product that you purchased contains rechargeable batteries. The batteries are recyclable. At the end of their useful life, under vari-

ous state and local laws, it may be illegal to dispose of these batteries into the municipal waste stream. Call 1-800-8-BATTERY for battery recycling options in your area or contact your dealer.

BASIC OPERATION

■ General

Operating the IC-R10 is easy. However, in order to get the most out of its operating potential, please go through the following procedures, step-by-step. Then, try the examples contained at the end of this chapter.

What is VFO?

The IC-R10 has several operating modes, each of which has its own distinct functions. VFO (Variable Frequency Operation) is one of these modes.

VFO mode is used to change the operating frequency, receive mode, tuning step, etc. Therefore, for most every day operations of the receiver, you will be using VFO mode.

■ Selecting VFO mode

2. Adjust the volume

Adjust the audio to a suitable level using [VOL].

Check the squelch position (see next page) or VSC function setting (p. 38) if no audio is emitted.

VFO

Presented

by ICOM

Opening message as above is displayed on the multi-function display.

3-1. Adjust the RF gain

Rotate [SQL] maximum counterclockwise, to adjust RF gain to optimum level.

What is RF gain?

RF gain controls receive sensitivity gain—reduce the gain when you don’t want to receive very weak signals or when excessively strong interfering signals are being received, etc.

4. Select VFO mode

When MEMORY mode is selected, push [V/M] to select VFO mode. When SET or TS set mode is selected, push [CLR] to select VFO mode.

•The VFO indicator appears.

BASIC OPERATION

3. Adjust the squelch

Rotate [SQL] maximum counterclockwise, then rotate it clockwise until audio is just muted when receiving no signal for FM, WFM or AM mode. (see right page)

What is squelch?

A squelch circuit allows you to mute undesired noise while receiving no signal and emit audio while receiving signals. This provides quiet standby. The [MONI] switch changes the squelch setting. This is useful for weak signal reception (p. 64).

BASIC OPERATION

■ Selecting a receive mode

What are receive modes?

Radio signals can be propagated in a variety of ways (or modes). Each mode has its own physical properties that determine to some degree its uses.

The IC-R10 receives the 6 most common modes: AM, FM, WFM, USB, LSB and CW. When you want to tune a station, you MUST set the receive mode ﬁrst. The table below shows common uses for each mode.

BASIC OPERATION

What are tuning steps?

Tuning steps are the frequency change increments when you rotate the tuning control or operate a scan. The following steps are available: 0.1, 0.5, 1, 5, 6.25,

8, 9, 10, 12.5, 15, 20, 25, 30, 50, 100 kHz and user programmable tuning steps (p. 66).

It is important to set the proper tuning step for the type of station you want to listen to. Some tuning steps are determined by frequency band or receive mode and others are set by tradition.

Generally speaking, if you set a tuning step smaller than that needed you will still be able to tune a station you want (or scan it), however, tuning (or scanning) will not be efﬁcient. On the other hand, if you select a tuning step which is too large, you may not be able to ﬁnd the station you are looking for.

Consult local listings.

1. Call up the tuning step set mode

Once you have selected VFO mode and the desired receive mode, while pushing [FUNC], push [

(MODE)TS].

2. Select the tuning step

1 Rotate [DIAL] to select the desired

tuning step.

2 Push [CLR] to return to VFO mode

after the selection.

■ Selecting a tuning step

BASIC OPERATION

When you know the exact frequency you want to listen to, the quickest way to tune it is by direct keypad entry.

Remember that the frequency must be between 0.5 MHz and 1300 MHz.

The diagram below shows the correlation between the function display frequency digits and the frequency.

1. Select the frequency

Select VFO mode and the receive mode in advance then: Push the numeral keys in the same order as the frequency you want to tune (including the decimal key).

•If you make a mistake, push [CLR] and start again.

2. Enter the frequency

When the frequency you want is displayed: Push [ENT] (or numeral keys for the

0.1 kHz digit) to enter it.

•When you select a frequency outside of the allowed range, the display will revert back to the previously displayed frequency.

BASIC OPERATION

■ T uning a frequency (via the dial)

When you want to listen to frequencies near the displayed frequency, the easiest way to tune them is with the tuning dial.

All signals have what is called an “oc- cupied bandwidth.” They will be received as long as the receiver is tuned anywhere within this bandwidth. Even though the frequency received may not be the central frequency, the tuning step should be made as small as possible (0.5 or 5 kHz) and the receiver tuned to the point of greatest signal strength indicator deﬂection.

To change frequencies faster than the tuning step, use the dial select function (p. 16).

1. Select VFO mode and a receive mode

q Push [CLR] or [V/M] to select VFO

mode.

w Push [MODE] to select a receive

mode.

e Set tuning step if desired (p. 14).

2. Tune a frequency

Rotate [DIAL] to change the frequency.

•The frequency changes in increments determined by the tuning step.

•To change the frequency faster, use the dial select function (p. 16).

BASIC OPERATION

■ Dial select steps

What are dial select steps?

When tuning with the dial, if you want to change the frequency faster than the selected tuning step can, use the dial select function.

A dial select step is an increment of frequency change much like a tuning step is. Unlike a tuning step however, a dial select step has no relation to the type of station you want to tune or to the scan operations.

BASIC OPERATION

■ Band scope function

What is the band scope function?

The band scope detects signal availability in the range of ±5 channels (up to ±100 kHz) from the displayed frequency, and displays the result on the multi function dot-matrix display. This gives you a visual reference of current band conditions.

In this case, channel refers to sweep step or channel space according to the set tuning step. For example, when the tuning step is set to 5 kHz, the band scope detects 25 kHz above and below the displayed frequency, then displays the result on the LCD.

When the tuning step is set above 20 kHz, the band scope function automatically changes its sweep step to 20 kHz. However, when the sweep step is changed to 20 kHz, the tuning step remains the same.

Also, when a user-programmable tuning step is selected, the band scope function automatically selects the 20 kHz sweep step.

Preparation

The band scope function is activated only when FM receive mode is selected in VFO mode.
