Installation
ELECTROMAGNETIC COMPATIBILITY
If this transceiver is used with, or in the vicinity of, a computer or computer-driven acces-
sories, you may need to experiment with grounding and/or Radio Frequency Interference
(RFI) suppression devices (such as ferrite cores) to minimize interference to your commu-
nications caused by energy from the computer. Computer-generated RFI is usually a result
of inadequate shielding of the computer's cabinet or 110 and peripheral connections. While
computer equipment may "comply" with RF emission standards, this does not ensure that
sensitive Amateur Radio receivers like the FT -100 will not experience interference from
the device!
Be certain to use only shielded cables for TNC-to-Transceiver connections. You may need
to install AC line filters on the power cord(s) of the suspected equipment, and decoupling
ferrite toroidal chokes may be required on interconnecting patch/data cables. As a last
resort, you can
try
installing additional shielding within the computer's case, using appro-
priate conductive mesh or conductive shielding tape. Especially check "RF holes" where
plastic is used for cabinet front panels.
For further information, consult amateur radio reference guides and publications relating
to RFI suppression techniques.
HEAT AND VENTILATION
To ensure long life of the components, be certain to provide adequate ventilation around
the cabinet of the FT-IOO. The cooling system of the transceiver must be free to draw cool
air in from the side of the transceiver and expel warm air from the rear of the transceiver.
Do not install the transceiver on top of another heat-generating device (such as a linear
amplifier), and do not place equipment, books, or papers on top of the transceiver. Place
the transceiver on a hard, flat, stable surface. Avoid heating vents and window locations
that could expose the transceiver to excessive direct sunlight, especially in hot climates.
