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-R5
receives RF energy from 0.150 MHz* to 1309.995 MHz and
converts it into audio frequency (AF) energy which in turn ac-
tuates 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 abbrevi-
ation of megahertz or 1,000,000 hertz, where hertz is a unit of fre-
quency.
OPERATING NOTES
The IC-R5 may receive its own oscillated frequency, resulting
in no reception or only noise reception, on some frequencies.
The IC-R5 may receive interference from extremely strong
signals on different frequencies or when using an external
high-gain antenna.
