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.
