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-R3 re-
ceives RF energy from 0.495 MHz* to 2450.00 MHz and con-
verts it into audio frequency (AF) energy which in turn
actuates 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 abbrevia-
tion of megahertz or 1,000,000 hertz, where hertz is a unit of fre-
quency.
OPERATING NOTES
The IC-R3 may receive its own oscillated frequency, resulting
in no reception or only noise reception, on some frequencies.
The IC-R3 may receive interference from extremely strong
signals on different frequencies or when using an external
high-gain antenna.
