General Information

Dual DSP-based, compact and affordable Radio Explorer II is a product with highly evaluated

performance. This device is the perfect solution for led surveys and on site monitoring of

station’s complete signal. A click on the button converts the Radio Explorer II into an excellent
tool for analyzing of the signal strength and quality after repairs or set-up of new equipment. This

cost-effective device can measure RF level, MPX deviation, Left & Right Audio levels, RF eld

strength, RDS and Pilot injection levels and display the measurements on the easy to read OLED
Graphical display.

The Radio Explorer II is a multifunctional device designed in line with all market requirements.
This mobile easy to use tool evaluates the FM broadcast band congestion and stores all important

radio broadcast parameters in a Log le. The built-in FTP system allows managing of the les by

an assigned schedule. All collected information is centralized in a database and can be revised,

played back, and sent automatically to the qualied staff if need be.

Designed for signal surveillance, on the eld where the listeners are, all that is needed is a

vehicle and Radio Explorer II. There are two distinct campaign modes:

Radio Explorer II can be set to measure automatically one or multiple preselected frequencies
(Up to 50);

RDS PI / RBDS Call campaign – up to 10 stations can be chosen. Radio Explorer II will
automatically detect the used frequency. While the campaign is running, the chosen stations will
be monitored; Radio Explorer II will automatically switch over between the variable frequencies
during movement - just as the car radio of your listeners.

When the campaign is over using the supplied free of charge Windows software, the log

les could be converted into KMZ format and visualized in Google Earth. Such functionality

is irreplaceable when current information of the FM broadcast band congestion and coverage is

needed. As an addition, the Log le can be also exported and saved as a transitional format for

future analysis.

The band scan mode guarantees real-time live visualization of the FM band or a particular

predened part of it, with down to 10 kHz resolution. Radio Explorer II can be controlled through:

The built-in Web server - a standard web browser can be used to monitor its status or make
some adjustments. Apple and Android devices are also supported. The Main Screen of the WEB
Interface shows all mandatory parameters represented as LED readings;

The supplied free of charge DEVA Device Manager Software - easy-to-use interface allows
quick and easy connection to the device. The dedicated module ensures managing of all the
device’s logs and displays all the events in a handy manner;

The very intuitive user interface with OLED screen, Front panel navigational and soft buttons
ensures an easy usage of the device’s build-in features.

Supporting both RDS/RBDS standards and measurement units, the Radio Explorer II is a
suitable choice for broadcast engineers from all around the world. For better control and data
representation the device can be connected to any Windows® based PC, via the LAN or USB port.
Offering various bar-graphs, data plots, histograms, etc., this device will meet the expectations of
the most demanding broadcasters.

Operating Modes

The Radio Explorer II is a multifunctional, easy to use tool, designed to evaluate FM broadcast

band congestion and to measure and store all important radio broadcast parameters in a Log le.

This is a stand-alone solution for running surveys - no additional tools are needed. You can setup
for observation up to 50 preselected channels.

The Radio Explorer II utilizes three modes of operation. We recommend choosing the proper

operating mode before the observation of the signal is commenced.

LOGGER MODE

This mode is used for on-eld conguration and observation. Use the front panel Navigational

Menu and OLED display to congure the Radio Explorer II or to observe a specic station and

GPS information. Radio Explorer II can be set to measure automatically one or multiple preselected
frequencies (Up to 50).

PI/CALL CAMPAIGN MODE

Up to 10 stations can be chosen. Radio Explorer II will automatically detect the used frequency.
While the campaign is running, the chosen stations will be monitored; Radio Explorer II will
automatically switch over between the variable frequencies during movement - just as the car
radio of your listeners.

This mode is used for running Campaign Surveys. It is necessary that the Campaign Channels

and supplemental Radio Explorer II settings be pre-congured before starting a campaign. No

additional adjustments or settings will be required, except for the occasion when the campaign is
to be stopped.

INTERACTIVE MODE

This is the recommended operating mode for stationary FM observation which allows the user
to perform a signal evaluation by changing the desired frequencies and monitoring the received
data.

Apart from allowing management of Radio Explorer II via the Front panel Navigational Menu,
WEB Interface and Software, this mode is perfect for Band scan campaigns.

Navigation through OLED Menu

Radio Explorer II can be operated in three methods: through the Front panel navigational menu,
DEVA Device Manager Software or via a standard WEB Browser.

NAVIGATIONAL BUTTONS

UP–DOWN, LEFT–RIGHT and OK buttons, like the Soft Buttons, are used to navigate through
the menus, for selecting various functions and parameters of Radio Explorer II. The Main Menu
structure has an up-and-down basis, expanded with left-to-right branches.

SOFT BUTTONS

Used for navigation through the menus, quick access to the parameters, modes, functions and to
alter their values. The Soft Buttons indicators are placed on the bottom side of the OLED display.
Depending on the currently selected menu context, the indicators change their function. The Soft
Buttons will be referred to as (left-to-right) SB1, SB2, SB3 and SB4.

The purpose of all Soft Button corresponds to the selected menu page. Most pages have the
same or similar functional areas. The corresponding functions as Function, Menu Page, Parameter
to be changed, etc., linked with the Soft buttons will appear as labels above them.

For example:

– Discard changes being made;
– HOME PAGE will be selected;
– Return to previous page;
– Alternating low threshold button;

NOTE: On some pages, the Header and Soft button area will disappear in order to expose the

content underneath.

LEVELS PAGE

Select the Levels icon from the Menu page and press the OK button to enter the menu.

The Levels page shows a bar graph representation of the signals measured by Radio Explorer II.
The parameters are divided into groups. Each bar graph displays the low, average and high values
of the signal. The number, placed below the bar graph - in the middle, represents the average value.
The shaded color number, placed on the left and right bottom edges, denotes the measurement
range of the signal. Measurement units and name of the signal are written above the corresponding
bar graph.

Group 1. RF carrier related parameters

The RF level at the selected antenna input is measured in dBμV. The RF attenuation is included
in the level calculation.

The Frequency offset of the RF carrier is measured in kHz. This signal measures the misalignment
between the modulation and demodulation frequency. As the misalignment is expected to be small,
a large offset will indicate disturbance (for example adjacent channel breakthrough).

The Frequency offset is measured with better accuracy if there is no modulation of the carrier.

The usable range depends on the selected IF lter bandwidth. For better results, we recommend
the IF lter bandwidth to be manually set to 153 kHz.

The Level of multipath reception is measured in percentages. The multipath detector measures

the amplitude uctuations of the signal. The FM signal is broadcast with a xed level; therefore
the level uctuations will indicate degraded signal quality. At multipath conditions, large level
uctuations can be measured. Install the antenna at the reception point with the lowest multipath

level in order to achieve better re-broadcast.

IF Bandwidth – Shows the currently IF lter bandwidth.

Group 2. Stereo multiplex related parameters

MPX Positive and MPX Negative – These bar graphs represent the positive and negative
deviation component of the MPX signal. In wide-band FM, used in wireless broadcasting, the
instantaneous frequency varies above and below the frequency of the carrier with no modulation.
The carrier frequency shifts in one direction when the instantaneous input wave is with positive

polarity аnd vise-verse - when the instantaneous input wave is with negative polarity, the carrier

frequency shifts in the opposite direction. At every instant in time, the extent of carrier-frequency
shift (the deviation) is directly proportional to the extent to which the signal amplitude is positive
or negative.

Mod Input

FM Output

Pilot – Represents the deviation caused by Pilot tone injection. Our practice shows that the pilot
deviation should be about 10% of the total deviation of the RF carrier.

RDS – Represents the deviation caused by RDS subcarrier. Our practice shows that the RDS
deviation should be about 5% of the total deviation of the RF carrier.

Group 3. Audio related levels

Group 4. Reception quality related levels

Ultrasonic Noise bar graph – Indicates the MPX signal amplitude in the approximate bandwidth
of 80 kHz – 150 kHz.

Stereo Blend bar graph – In stereo signals, the difference (L-R) component of the MPX signal
is more susceptible to disturbances than the sum (L+R) signal. Therefore, the separation of the left
and right audio channels can be decreased in order the audibility of the disturbance to be reduced.
This channel separation reduction is called “stereo blending”. A value of 100% indicates that no
reduction is applied. The level of stereo blending depends on the following input signals: RF
Signal Level, Multipath, Ultrasonic Noise and Pilot tone deviation.

High Cut bar graph – Audio disturbance effect is generally present in the high frequencies.

Therefore, a means of reducing the effect of disturbances is to lter the high frequencies. The

audio bandwidth reduction is called “high cut”. A value of 100% indicates that no “high cut” is
applied. The applied High Cut level depends on the following input signals: RF Signal Level,
Multipath and Ultrasonic Noise.

Response of the FM High Cut function for several reduction values

Soft Mute bar graph - If a disturbance is present in the received signal, the perceived effect can
be reduced by attenuating the audio signal. The reduction of audio volume is called “soft mute”.
A value of 0% indicates that no “soft mute” is applied. Soft Mute depends on the following input
signals: RF Signal Level, Multipath and Ultrasonic Noise.

HOW TO START A PI OR LOGGER CAMPAIGN USING THE FRONT PANEL MENU?

IMPORTANT: Prior to the set-up procedure:

• You will have to note that the campaigns (PI and Logger) cannot be performed simultaneously.
The PI campaign is with higher priority, thus in order for a Logger mode campaign to be
performed you will have to make sure that the PI Campaign is disabled.

• If the channels that you would like to monitor in RDS PI / RBDS CALL mode do not have
PI/CALL signs based on which the monitoring is made in this mode, we recommend you to
use the Logger mode.

In order to set up a campaign via the front panel menu, the following steps should be completed:

1. Press the [OK] button to enter the Main Menu> Settings and again press [OK];

2. Then select PI Campaign> PI Channel I;

3. Specify name of the PI and for ‘Active’ - select Antenna 1;

4. Change the Acquisition time as per your preferences. We recommend setting it to 10 seconds;

5. Steps from 2 to 4 should be applied for each of the channels to be monitored. Once all PI
Channels are set you can proceed to the last step

6. Go to Settings> PI Campaign> PI Campaign Mode and as a value set 10 seconds. In order

for a campaign to be commenced the device should be inactive for the specied time.

The settings for Logger mode are identical with the PI Campaign settings, except for the menu

path which is Main Menu> Settings> Logger> ...

NOTE: The front panel inactivity time should expire prior the PI Campaign countdown to

begin.

PI CAMPAIGN AND LOGGER MODE

Differences between PI campaign and Logger Mode.
Which type of campaign should I choose?

Designed for signal surveillance on the eld where the listeners are, all that is needed is a

vehicle and Radio Explorer II. There are two campaign modes:

1. Logger mode – Trough this section of the WEB Interface, up to fty radio frequencies could

be chosen and monitored, by applying the needed settings. When the desired adjustments
are made, Radio Explorer II will monitor all of the selected frequencies at regular intervals.
All of the collected information is accessible through the built-in FTP Server;

2. RDS PI / RBDS CALL campaign – Radio Explorer II can monitor up to ten stations at

regular intervals. When used in this mode, Radio Explorer II will automatically detect the
used frequency. While the campaign is running, the chosen stations will be monitored;
Radio Explorer II will automatically switch over between the variable frequencies during
movement - just as the car radio of your listeners. It is necessary that the campaign

frequencies/channels and supplemental Radio Explorer II settings be pre congured before

starting a campaign. No additional adjustments or settings will be required, except for the
occasion when the campaign is to be stopped.

RDS PI / RBDS CALL campaign - PI campaign

• The PI campaign is suitable solution when monitoring of an entire network is made. In

order for a PI/CALL campaign to be made, the channels you would like to monitor must
have RDS PI / RBDS CALL signs.

• This campaign type is very convenient when it is not preliminary known which transmitters

will be in the range of the survey, but the PI or CALL signs of the stations are available.

• When used to monitor an entire network, the PI campaign allows you to set-up the PI/CALL

signs once and use them in campaigns for unlimited time without the need of changing them
depending on the region of survey.

• Allows you to identify the zones of switch over from one transmitter to another.

Logger mode

• The Logger mode is suitable solution when monitoring of a preliminary identied frequencies

should be made.

• This campaign type is very convenient when a survey for the coverage of one transmitter in

a particular city or region should be made.

• Appropriate when several transmitters in a relatively small region should be monitored and

all channels of interest are broadcasted at the same time/simultaneously.

Upon completion of the campaign, the data from the log measurements of the signal, will
be presented as a graphic, located on a map. The graph is formed by examining points which
follow a certain sequence and forming the resultant “travel path”. Using the supplied free of charge

Windows software the log les could be converted into KMZ format and visualized in Google

Earth. Such functionality is irreplaceable when current information of the FM broadcast band

congestion and coverage is needed. As an addition, the Log le can be also exported and saved as

a transitional format for future analysis.

The LOG les can be downloaded via a standard FTP client or trough the DEVA Device
Manager Software. For detailed information on how to download the les via:

- FTP - For information on how the connection between the Radio Explorer II and an FTP

Client should be congured, please refer to “APPENDIX B : Download les via FTP” on page 79.

downloading from our website - www.devabroadcast.com/downloads

WEB Interface control options explained

PI Campaign / Logger subsection – generally enables/disables the campaign. In order for a

campaign to be performed, the setting should be enabled and set to the desired time.

Channel validity rules – When the RF level of channel at which the Radio Explorer II is

currently tuned is below the specied threshold, the data collection will be stopped and the unit
will switch to the next channel. Correctly set, this parameter will lter the unneeded information
if the eld intensity in the analyzed point is below the specied RF threshold. The value is user
dened and is set depending on the antenna used. If the Radio Explorer II is to be used with

the included in the set antenna, the recommended value of the RF Threshold is 25 dBµV. If the

default value is left, the analyzed points will not be ltered and there might be points with missing

information on the map.

Buttons [Ch.1 - Ch,5], [Ch.6 - Ch.10] to [Ch.46 - Ch.50] are used for easy navigation through
the list of all monitored stations.

[Export] and [Import] are options identical for both the PI Camp and Logger, and are explained

Important recommendations when acquisition time is set

Acquisition time denes the time between the examining points. Meaning that if the acquisition

time is set to 10 seconds, the Radio Explorer II will mark a point on the map each 10th second of
the campaign. Having in mind that the device will scan the channels preset after preset, the driving
speed should be carefully considered.

Below is a table with the expected distance between the measurements of a particular
point/frequency, depending on the speed and number of monitored channels, when the device
is used in Logger Mode. Please note that the cited parameters are approximate and depend

onthere-tuningtimebetweenthechannels,andtheoverallconguration.Asitcanbeseen

from the table, the time period for two channels is more than two times bigger than the one

APPENDIX A

RDS: EUROPE VS AMERICA

The European Broadcasting Union (EBU) and its member countries originated the concept of

“Radio Data” transmission. The European RDS specication, CENELEC Standard EN50067, was
rst published in 1984. It was revised in 1986, 1990, 1991 and 1992.

European RDS has grown in use following initial adoption of the Standard. RDS is nearly

universal throughout Europe; it is almost impossible to nd a European FM broadcasting station

that does not carry a radio data subcarrier.

The popularity of RDS in Europe is very much in contrast with initial reluctance on the part
of US broadcasters to embrace this technology. This can be ascribed to material differences in
broadcasting practices.

Almost without exception, FM broadcasting in the United States is ‘detached’ and independent

- each station originates its own programming. America’s National Public Radio might be
considered as an exception, though for most of the broadcast day even NPR stations originate, or
at least schedule, their own programs.

Most of European broadcasting is similar to the concept of network radio that was common in
the US prior to the 1950s. In Europe, a central program originator may have many transmitting
facilities of modest power situated throughout the country, at several different frequencies to
blanket a designated service area. The European disposition, toward lower-power transmitters can
be found on the “local radio” level, as well.

The European concept of a service area equates to the US broadcaster’s market. The subtle
difference between these designations further characterizes broadcasting practices and ethics.

RDS benets the European broadcaster through almost an altruistic endeavor to be of service to

his listeners. The US broadcaster is marketing his programming and is primarily interested in how
he can create additional revenue from RDS.

THE RDS SYSTEM

RDS is a digital data channel, transmitted as a low-level subcarrier above the range of the
composite stereo program signal in the FM baseband. The data transmission (baud) rate is
comparatively low, yet it is quite robust because of data redundancy and effective error correction.

It is not within the scope of this Manual to cover the details of RDS subcarrier coding and

modulation. For this, the reader is directed to the Specication appropriate to his location either
the CENELEC EN50067 Specication for Europe or the United States NRSC Specication. Since
the Manual will deal with specic implication of RDS implemented with the Radio Explorer II, it

is assumed that the user is familiar with the RDS concept.

APPENDIX B

DOWNLOAD FILES VIA FTP

In order for a connection to be established the following setting should be applied:

FTP Server Settings

The built-in FTP Server has four important parameters that should be congured: Command

Port, Data Port, User name and Password. These parameters are to be used in the FTP client’s

connection conguration. Further information on how to change the FTP Server’s settings and

their respective default values can be found in the device’s User manual.

WE RECOMMEND the usage of FileZilla. This is a widespread open source software

distributed free of charge, hence available for downloading from the Internet.

NOTE: The FTP Server can manage only one connection at a time. The FTP Server works in

Passive mode. Hence, the FTP Client should also be set in passive mode.

IP Router and Port Translation Settings

If the connection to the device is made through a Network address translation (NAT) router or

rewall, the port forwarding feature of the router should be congured. The port forwarding is
usually set in the rewall section of the router’s menu. As each router has different port forwarding
procedure, we recommend you to refer to its complete manual. To allow proper data ow through

the router, the FTP Command and FTP Data ports should be open.

NOTE: The FTP port numbers to be used in the port forwarding feature conguration can be

found in the device.

APPENDIX B.1

RDS APPLICATIONS SUPPORTED

Following is an alphabetical list of the RDS applications supported by Radio Explorer II. The
standardized RDS application abbreviation is followed by an expansion of the application name
and a short explanation of the function.

NOTE: Depending of the currently selected User interface the following RDS Applications are

supported:

• Via WEB Interface: AF, CT, DI, M/S, PI, PIN, PS, PTY, RT, RT+, TA, TMC and TP

• Via Logger: PI, PTY, TA, TP, M/S, DI, PS, AF, RT

• Via DEVA Device Manager Software: All RDS Applications

AF

List of Alternative Frequencies: In order holes in the coverage area to be lled, list of all

frequencies where identical program could be heard simultaneously can be included by the network
broadcaster or one with low-power rebroadcast transmitters (translators). The RDS receiver
(particularlythe upscale car radio) constantly searches for the best signal that carries the same
program. The radio will re-tune without noticeable interruption, when a better signal is found.
The principal utility of this RDS function is with European radio networks and US stations with
‘translators.’

CT

Clock Time and date: Time and date codes should use Coordinated Universal Time (UTC) and

Modied Julian Day (MJD). If MJD = 0, the receiver should not be updated. The listener, however,

will not use this information directly and the conversion to local time and date will be made in
the receiver’s circuitry. CT is used as time stamp by various RDS applications and thus it must be
accurate.

DI

Decoder Information: This is one of several ‘ags’ that convey yes/no or other very basic data.
This ag helps the receiver to indicate whether the broadcast is monaural or is transmitted in any

of several methods of stereo or binaural broadcasting. As many as 16 encoding options may be
accommodated! This is a rather esoteric function and, thus far, remains unused both in Europe and
in the US.

ECC

Extended Country Code: RDS uses its own country codes. The rst most signicant bits of the
PI code carry the RDS country code. The four bit coding structure only permits the denition of 15
different codes, 1 to F (hex). Since there are much more countries to be identied, some countries
have to share the same code which does not permit unique identication. Hence there is the need

to use the Extended Country Code which is transmitted in Variant 0 of Block 3 in type 1A groups

and together with the country identication in bits b15 to b12 of the PI code render a unique

combination. The ECC consists of eight bits.

Tel: [phone], Fax: [phone]

EON

Enhanced Other Networks information: This feature can be used to update the information
stored in a receiver about program services other than the one received. The alternative frequencies-

PS name, Trafc Program and Trafc Announcement identication as well as Program Type and

Program Item Number information can be transmitted for each other service. The relation to the

corresponding program is established by means of the relevant Program Identication. Linkage

information, consisting of four data elements, provides the means by which several program
services may be treated by the receiver as a single service during times a common program is
carried. Linkage information also provides a mechanism to signal an extended set of related
services.

EWS

Emergency Warning System: The EWS is intended to provide coding for warning messages.
These messages will be broadcasted only in case of emergency and will be evaluated by special
receivers.

IH

In House application: This refers to data to be decoded only by the operator. Some examples

noted are identication of transmission origin, remote switching of networks and paging of staff.

The applications of coding may be decided by each operator itself.

M/S

Music / Speech Switch: This ag simply indicates whether music or speech is the primary

broadcast programming. The purpose of this function is not well explained in the respective
Standards; hence it comes as no surprise that it is not widely used.

ODA

Open Data Applications: The Open Data Applications feature allows data applications, not

previously specied in EN 50067, to be conveyed in a number of allocated groups in an RDS

transmission. The allocated groups are indicated by using type 3A group which is used to identify
to a receiver the data application in use in accordance with the registration details in the EBU/RDS
Forum - Open Data Applications Directory and the NRSC Open Data Applications Directory.

PI

Program Identication: This block of data identies the broadcast station with a hexadecimal

numerical code, which becomes the “digital signature” of the station. The code is assigned by the
broadcasting authorities in most countries, but in the US it is calculated from a numerical encoding
of station call letters. The receiver processes the PI code to assist automatic tuning features (station
memories), and to prevent false switching to alternative frequencies that might be shared by
broadcasters in nearby regions.

PIN

Program Item Number: The code enables the designed to use this feature receivers and recorders
to respond to the preselected by the user program item(s).This feature is used via scheduled program
time, to which in order to avoid ambiguity is added the day of the month.

E-mail: of[e-mail] ,Web: www.devabroadcast.com

Tel: [phone], Fax: [phone]

PS

Program Service Name: This is the station’s “street name” that will appear on the receiver
faceplate display. The PS can be up to eight characters in length (including spaces) and can be as
simple as the station’s call letters: KWOW or KWOW FM, or a slogan: NEWSTALK or LIVE 95.
The Program Service Name is automatically displayed, even on the automobile receivers. Because
of driving safety considerations broadcasters are generally discouraged from scrolling messages

in this eld.As a matter of fact, it is a violation of both the CENELEC and the NRSC standards to

scroll the PS display, although the practice has become universally common.

PTY

Program Type: The PTY data ag identies the station format from a collection of pre-dened

categories. Many RDS receivers are able to seek the listener’s preferred format automatically.
This means that a car radio can switch from a fading station to a stronger one that carries the
same variety of music, though not the very same program, as provided by AF switching. The
PTY function of RDS helps a broadcaster catch ‘transient audience’ share. A listing of the PTY
categories is given in “APPENDIX C.1” on page 85 and “APPENDIX C.2” on page 86.

Under some programming circumstances, the PTY identier may be made ‘dynamic,’ changing
between categories for a station that “dayparts” (changes its format for specic time periods).

The PTY code is not meant to change from song to song or to accommodate a top-of-the-hour
newscast, however.

PTYN

Program TYpe Name: The PTYN feature allows the predened by the RDS/RBDS Standard
PTY to be further described using user-dened text (e.g. PTY=4: Sport and PTY=8: Football). The

PTYN is not intended to change the default eight characters of PTY which will be used during
search or wait modes. Its purpose is to show in details the program type once tuned to a program.

If the broadcaster is satised with the default PTY name, it is not necessary to use additional

data capacity for PTYN. The Program Type Name is not intended to be used for automatic PTY
selection and must not be used for giving sequential information.

RT

RadioText: This is a 64-character block of plain text that the listener can select for visual display
on the faceplate of the radio by pressing an INFO button on the receiver. This function is not
available on many automobile radios for safety reasons, which has precipitated the frowned-upon

practice of scrolling the PS eld instead.

Most radios have limited alphanumeric display capability, so the 64 characters of RadioText
march across the front panel, much akin those annoying LED advertising signs found in airport
buses or fast food emporia. Like the scrolling-PS implementation, RadioText can announce song
titles and performers, run special promotions or contests, or broadcast sponsors’ messages.

RT+

RadioText Plus is “semantic analogue radio”. It allows the RDS feature RadioText (RT) to be
read by the FM RDS receiving terminals. Based on the RDS RT messages, RT+ is completely
backwards compatible with RT. The usage of RT+ allows the listener/user to derive additional

benets from the RDS Radio Text service. It enables FM RDS receivers to “read” Radio Text
(to recognize designated objects and make them manageable) by user’s direct access to specic

elements of the Radio Text messages. For example, that element could be programme associated
metadata like Title and Artist of the currently playing song or a news headlines. This provides the
listener with an “mp3-player feeling” while listening to analogue FM radio. The elements can also
carry additional service messages or information about the Radio Station such as the telephone
number or the web address of the Radio Station’s hotline. These objects, or more accurately RT+

information elements carried in the RDS RadioText (RT) messages, are identied by their location

within the RT messages and by the class code of their content type. Once an information element
is received and understood, a receiver is able to, for example, store the different RT+ information

elements and the listener may then select and request a specic content type from the radio’s

memory at an instant in time that suits the listener’s needs. Thus the listener is no longer forced
to watch the RT information passing (scrolling) by. Moreover, RT+ offers selected RT message
elements to car drivers on a static display, without risk of distracting the attention of the driver.
Furthermore, RT+ is well suited for mobile phones with built-in FM receivers: telephone numbers
can be directly used to initiate calls, and web addresses can be used to start browsing the web
content offered by the radio programme provider. Last but not least, RT+ is also used for satellite
radio broadcasting via DVB-S. It may be adopted by DRM and DAB in the future, too.

TA

Trafc Announcement: This is a temporary ag added to the RDS data stream only as a trafc
bulletin is being aired. Some RDS car radios can be set to search for trafc bulletins among various

TP stations (see TP below) while tuned to a listener’s preferred program, or even while playing

a tape or CD. As soon as any TP station broadcasts a trafc bulletin, the receiver temporarily
switches-over to receive it. When the bulletin is nished, the receiver switches back to the original

program, tape or CD.

TDC

Transparent Data Channels: The transparent data channels consist of 32 channels, which may
be used to send any type of data.

TMC

Trafc Message Channel: This feature is intended to be used for the coded transmission of
trafc information.

TP

Trafc Program Identication: The TP ag identies the station as one that routinely broadcasts
trafc bulletins for motorists as part of its normal, everyday programming. When the TP ag is
displayed on the receiver faceplate, the radio is searching for trafc announcements. The radio

keeps track of TP stations offering this service to speed up the search-and-switch process.
