INSTALLATION AND CONNECTIONS

Using the desktop stands

The transceiver has legs for desktop use.

z Pull-out the legs on both sides until they lock in

place.

NOTE: DO NOT hold the stand, dials and controls when you carry the transceiver. This may damage them.

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.

Never place the transceiver in areas such as:

• Temperatures below 0°C (+32°F) or above +50°C (+122°F).

• An unstable place that slopes or vibrates.

• In direct sunlight.

• High humidity and temperature environments.

• Dusty environments.

• Noisy environments.

Heat dissipation

• NEVER install the transceiver in a place without

adequate ventilation. Heat dissipation may be reduced, and the transceiver may be damaged.

• DO NOT place the transceiver against walls or put

anything on top of the transceiver. This may block

airow and overheat the transceiver.

• DO NOT touch the rear panel after transmitting

continuously for long periods of time. The panel may become hot.

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.

Connecting an external DC power supply

Be sure that the power supply power is OFF before connecting the DC power cable. We recommend using Icom’s optional PS-126 (13.8 V DC/25 A) power supply.

• SOFT

The lter shoulders are roundly formed as in analog

lters. This decreases noise components in the high and low frequencies of the lter passband

and increases the S/N of the target signal. These characteristics play an effective role in picking up very weak signals in the 50 MHz band, for example. The shape factor is kept, and the sharpness of the bandpass is excellent.

About the internal antenna tuner

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

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.

L 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)

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.

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.

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
