Installation And Connections; Selecting A Location; Grounding; Antenna Connection - Icom IC-7600 Instruction Manual

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-7600, see 'Supplied acces-
sories' on p. i of this manual.

Selecting a location

Select a location for the transceiver that allows ade-
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 adjustable feet
for desktop use. Set the feet to one of two angles
depending on your operating preference.

Grounding

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 ground rod. Make the distance between the
[GND] terminal and ground as short as possible.
R WARNING: NEVER
terminal to a gas or electric pipe, since the connec-
tion could cause an explosion or electric shock.

INSTALLATION AND CONNECTIONS

Antenna connection

For radio communications, the antenna is of criti-
cal importance, along with output power and receiver
sensitivity. Select antenna(s), such as a well-matched
ø
50 antenna, and feedline. We recommend 1.5:1 or
better of Voltage Standing Wave Ratio (VSWR) on
your operating bands. The transmission line should
be a coaxial cable.
When using a single antenna, use the [ANT1] con-
nector.
CAUTION:
Protect your transceiver from light-
ning by using a lightning arrestor.

Antenna SWR
Each antenna is tuned for a specified frequency
range and SWR may be increased out-of-range.
When the SWR is higher than approx. 2.0:1, the
transceiver's power drops to protect the final tran-
sistors. In this case, an antenna tuner is useful
to match the transceiver and antenna. Low SWR
allows full power for transmitting. The IC-7600 has
an SWR meter to monitor the antenna SWR contin-
uously.
