Radio Reception
Radio Signal
The radio signal is sent from a broadcast station and is then received by an antenna. The strength of the signal received depends on the following:
| • | The power output (wattage) of the broadcasting station |
| • | The location of the vehicle (or receiver) relative to the broadcast tower. |
| • | Obstacles between the tower and the receiver |
| • | Atmospheric conditions |
| • | What band (AM or FM) the station is broadcasting |
| • | Type of antenna and the ground plane |
AM Reception
The AM band has a lower frequency range than the FM band. These longer wavelengths:
| • | Bend around Obstacles |
| • | Follow the curvature of the earth |
| • | May reflect off the ionosphere (skip) |
The AM frequencies have longer range due to the ground wave. The ground wave follows the curvature of the earth and is effected by its conductivity. Greater conductivity equates to less signal loss thus transmission over water is better than over land. The AM band has a range of 80-320 km (50-200 miles).
FM Reception
The shorter wavelengths of the higher frequency FM band:
| • | Reflect off obstacles |
| • | Are absorbed by the ground |
| • | Penetrate the ionosphere |
Broadcasts in the FM band are limited to "line of sight" reception which is typically 40 km (25 miles). Even when out of a direct line of sight, the signal may be reflected into areas that would be in a "shadow" otherwise. Factors which affect the line of sight include:
| • | Height of the broadcast antenna |
| • | Height of the receiving antenna |
| • | Terrain and buildings in the broadcast path |
Audio Amplifier -- UZ6
The radio, digital radio receiver, or the CD changer supplies low level audio signals to the audio amplifier in order to boost the signal sent to the speakers.
The radio uses the antenna input signal to create a stereo audio output signal, which is sent at the user-defined volume level to the audio amplifier. The audio amplifier amplifies the signal and sends it to the appropriate speakers. Tone, balance and fade information is sent by the radio to the audio amplifier via a control circuit.
Remote Playback Device -- U1A
The radio controls and communicates with the remote playback device via the control circuit.
Remote CD Changer
The remote CD changer allows for multiple compact discs to be played continuously without having to manually change compact discs. Normal size discs may be played using the slots supplied in the magazine. The magazine must first be loaded with discs before it can played. To load CD's, insert the CD's from top to bottom, placing the discs in the magazine label side up. If a disc is loaded label side down, the disc will not play and an error will occur. Care should be used to align and insert the disc into one disc tray only. Repeat this procedure for loading all of the discs in the magazine. Once the discs are loaded into the magazine, open the door on the changer and push the magazine into the changer in the direction of the arrow marked on the magazine and close the door. When the CD magazine is loaded, the changer will begin checking for discs in the magazine. This will continue for up to one and a half minutes, depending on the number of discs loaded. To eject the magazine from the player, slide the CD changer door open. NOTICE: If the CD magazine fails to eject after the door is opened, do not attempt to pry the magazine from the CD changer. Whenever a CD magazine with discs is loaded in the changer, the CD changer symbol will appear on the radio display.
Radio Data System (RDS)
All three audio systems are equipped with technology known as the Radio Data System (RDS). RDS is a system that sends data along with the audio of the FM station you are currently tuned to. RDS is a standard that defines how a FM broadcast station may send digital data along with the audio program. Think of it as a one way wireless modem, allowing the broadcaster to send information about his program to your receiver.
RDS data is carried in what is known as a "subcarrier". A subcarrier is a frequency that the FM broadcaster is authorized to use to send data or other audio programs that are not audible in the main audio program. RDS information can be used to display program information and to control the radio.
To receive the RDS signal, all that is needed is an FM receiver with a RDS circuit. A special integrated circuit capable of dealing with the RDS signal is in the RDS circuit and passes it along to the receiver's microprocessor where it is decoded and acted upon.
RDS Basic Information
RDS basic information:
| • | RDS functions are provided in the FM broadcast band only. |
| • | RDS functions will only work with FM broadcast stations that are broadcasting RDS data. |
| • | Not all FM Broadcast stations broadcast RDS data or offer all of the RDS services. |
| • | RDS functions may not work properly when reception is weak, reception is of poor quality, or RDS is not implemented properly by the FM Broadcaster. |
In some cases, a radio station broadcasting incorrect information may cause the RDS features of the radio to appear to work improperly.
Broadcast RDS information can be used in a variety of ways by the receiver and listener, but basically falls into two categories: Display and Control.
Displaying Program Information
RDS displays textual information such as:
| • | The name of the station. |
| • | The type of program. |
| • | General information such as artist and song title, call in phone numbers, etc. |
Finding an RDS Station
To find an RDS station press the RDS button. The radio will seek to the next RDS station.
