2INSTALLATION AND CONNECTIONS

Unpacking

After unpacking, immediately report any damage to the delivering carrier or dealer. Keep the shipping cartons.

For a description and a diagram of accessory equip- ment included with the IC-7000, see ‘Supplied acces- sories’ on p. i-1 of this manual.

Selecting a location

Select a location for the transceiver that allows ade-

Antenna connection

For radio communications the antenna is of critical im- portance for output power and sensitivity. Use well- matched 50-ohm antennas and coaxial feedline. An SWR (standing wave radio) of 1.5:1 or lower is recom- mended when transmitting.

CAUTION: Protect your transceiver from lightning by using a lightning arrestor.

PL-259 CONNECTOR INSTALLATION EXAMPLE

quate air circulation, free from extreme heat, cold, or vibrations, and away from TV sets, TV antenna ele- ments, radios and other electromagnetic sources.

The base of the transceiver has an adjustable stand for desktop use. Set the stand to one of two angles de- pending on your operating conditions. (see description on right hand page)

Slide the coupling ring down. Strip the cable jacket and soft solder.

Strip the cable as shown at left. Soft solder the center con- ductor.

Grounding

e

solder solder

To prevent electrical shock, television interference (TVI), broadcast interference (BCI) and other prob- lems, ground the transceiver through the GROUND terminal on the rear panel.

For best results, connect a heavy gauge wire or strap to a long, buried copper rod. Make the distance be- tween the [GND] terminal and ground as short as pos- sible.

r

Slide the connector body on and solder it.

Screw the coupling ring onto the connector body.

R WARNING: NEVER connect the [GND] ter-

minal to a gas pipe or electric conduit, since the

connection could cause an explosion or electric shock.

ANTENNA SWR

Each antenna is tuned for a specified frequency range and SWR increases outside that range. When the SWR is higher than approx. 2.0 : 1, the trans- ceiver’s power drops to protect the final transistors. In this case, an antenna tuner is used to match the transceiver and antenna. Low SWR allows full power for transmitting even when using the antenna tuner. The IC-7000 has an SWR meter to monitor the an- tenna SWR continuously.
