DB7007 is a second generation digitally-tuned FM Re-Broadcast Receiver. Considering the
needs of the most demanding broadcasters and continuously supplementing new features to our
devices, DEVA has enhanced DB7007 to be smarter and fully functional unit, equipped with two
high-selective DSP-based FM tuners.
Thanks to the built-in monitoring system, upon audio loss at the inputs, DB7007 will not only
notify the maintenance staff, but will also automatically switch to the second back-up RF Station.
In case a fail of the second station is detected, DB7007 will shift to the incorporated IP Stream,
MP3/AAC back-up audio source player. It is essential that the back-up sources priority is user-
dened. The audio les and playlists can be uploaded in the device’s internal memory directly
from your PC, via any FTP client. When the signal at the default input is restored, the DB7007 will
automatically switch back to it. Depending on your preferences, several types of alarm notications
are utilized - E-mail, SNMP and SMS (via the optional GSM modem).
The DB7007 has an easy to read, high-resolution OLED graphical display, front panel alarm
indicators and ultra-bright bargraphs with up to 40 LED segment indicators that allow reading at a
glance of the MPX, Left and Right audio and the RF level, as well. The RF (IF) signal is digitized
as soon as it enters the device and all signal processing is then made through DSP algorithms,
thus guaranteeing measurement reproducibility over time. The IF bandwidth lters guarantees
unprecedented signal selectivity, while the difcult adjacent-channel problem will be completely
solved. DEVA advanced DB7007 will measure all important parameters of the FM transmission.
Additionally, the RDS information contained in the processed MPX signal is easily visualized
and represented as RDS/RBDS Data and detailed RDS/RBDS Statistics. The utilized Band
Analyzer function presents an overview of all available FM signals, plus the RF signal strength.
Scans can be performed within any section of the FM band in 4 different frequency steps. The
consequently generated spectrum diagram visualizes the relation RF Level vs. Frequency.
Adhering to the underlying principle of all DEVA products to be as much user-friendly as
possible, the DB7007 can be also easily controlled through the built-in Web server - you can use a
standard web browser to monitor the status or to make any adjustments (iOS and Android devices
are also supported); the supplied free of charge DEVA Device Manager Software or alternatively,
through the very intuitive user interface.
Designed to ensure premium broadcasting experience, DB7007 will meet and even exceed
your expectations for a rst rank re-broadcast receiver.

RF ENVIRONMENT – PRECAUTIONS,
INSTALLATION SPECIFICATIONS AND ANTENNA TYPES
The observation of the RF Environment, in which DB7007 is functioning, is necessary for
ensuring normal and reliable function of the device. In order for the device to work properly, the
best conditions according the standards listed below should be provided.
The usage of an external antenna is required because DB7007 is used for off air re-broadcasting
away from the transmitter site. Proper outdoor FM antenna, antenna location and direction should
be selected. The three most popular antenna types are: omni directional, unidirectional dipole and
directional multi-element array antenna.
Because of the low antenna gain, the bad signal to noise ratio (compared to any directional
antenna) and its high multipath interfaces reception, we do not recommend the usage of omni
directional antenna with DB7007.
The other type antennas: unidirectional dipole and directional multi-element array antenna are
much proper for your needs. We recommend the usage of factory made antenna or antenna system,
manufactured specially for the FM Radio Band 88 – 108 MHz.
The recommended working RF signal strength is in the range of 55-90 dBμV. If the input RF
level is above this range, we recommend using external RF attenuators with attenuation value
between 20 – 90dB.
After selecting the antenna type that will meet your needs, the next step is its installation. The
following important principles should be considered:
- Install the antenna far enough from walls, roofs, buildings or any transmitting equipment;
- The minimum spacing between the antenna and the closest object should be more than 3
meters.
One unit DB7007 re-broadcast receiver is used for re-broadcasting of one transmitter site,
transmitting more than one program. In such cases, the best antenna that can be used is a directional
antenna directed exactly to this site.
DE-EMPHASIS AND PRE-EMPHASIS SELECTION
As well known, there are three different de-emphasis selections. One of the problems with the
high quality VHF FM transmissions is that the increased audio bandwidth means that background
noise can often be perceived. It is particularly noticeable towards the treble end of the audio
spectrum, where it can be heard as a background hiss. To overcome this, it is possible to increase
the level of the treble frequencies at the transmitter. The frequencies are correspondingly attenuated
at the receiver in order to restore the balance. This also has the effect of reducing the treble
background hiss which is generated in the receiver. The process of increasing the treble signals
is called pre-emphasis, and reducing the treble signals in the receiver is called de-emphasis. The
rate of pre-emphasis and de-emphasis is expressed as a time constant. It is the time constant of the
capacitor-resistor network used to give the required level of change.
In UK, Europe and Australia the time constant is 50μs whereas in North America it is 75μs. The
de-emphasis and pre-emphasis should be selected depending on the region you are located or can
be disabled.

The signal strength is a major factor when a signal is re-broadcasted, measured and evaluated.
FM compared to AM is less susceptible to the inherent noise of the radio reception.
When speaking about FM broadcasting, it is the monaural reception which can tolerate and
prot from a much narrower IF bandwidth. The stereo reception adds all noise present in the 23 –
53 kHz sub-band. The amplitude component (AM) of the sub band is converted down to audible
noise and added to the program signal. That is why the noise performance of FM-stereo can be as
much as 20 dB worse than that of monaural broadcast.
Better reception and measurement can be obtained by using highly directional outdoors antenna.
This will improve the signal strength and contribute in eliminating the multipath distortion.
Multipath Distortion
In FM reception, regardless of overall signal strength, a very important consideration is that
obstacles, which an FM signal may encounter in the line-of-sight path tend to reect and disperse
the signal in many directions. In many locations, especially in urban areas where many tall
buildings interfere with the direct transmitted signal or in suburban areas surrounded by hills or
mountains, an FM receiver may pick up a station’s primary signal but, also, several secondary
reections coming from various directions. These reections arrive at the receiver out-of-phase,
slightly delayed in time with the primary signal and tend to blur or distort the principal signal. The
degree of distortion depends on the number and relative strength of the reections.
The result, known as multipath distortion in FM reception can range from a low-level fuzziness
to a severely distorted sound quality, particularly at the high frequencies or treble. Multipath
distortion is especially troublesome in FM stereo reception.
DB7007 has a multipath distortion detector and Front panel multipath LED indicator with
adjustable threshold. A bar graph indicator representing the multipath level of the received signal
can be reached under LEVELS menu.

In many populated areas, there is not enough space in the radio spectrum and stations might
be jam-packed. Poor frequency planning may also result in the mutual interface between the
broadcasting stations.
The inherent broad bandwidth of DB7007 re-broadcast receiver is vulnerable from stations
working on the nearby frequencies, where signal strength will be the most important factor – the
stronger the interfering station, the stronger the interference effect.
We recommend you to observe the independent positive and negative deviation readings in
order to identify adjacent channel interference. If the positive deviation is higher than the negative
one, interference from a strong station above the monitored frequency would be indicated and
vice–versa. For example, the negative deviation can probably be trusted as an indication of total
carrier modulation, though this should be conrmed in free of interference RF environment.
Anyhow, the program deviation should be fairly symmetrical about the carrier frequency. Using
the built-in Attenuator can be of some help, but the usage of an outdoors directional antenna could
improve the situation with unwanted adjacent working stations. Other solutions include a band-
pass lter at the primary frequency or a trap at the interfering frequency.

Enter the Main Menu page and select the Level icon, press [OK] button to enter the menu.
Levels page shows bar graph representation of the different signals, measured by DB7007. The
parameters are divided into groups. Each bar graph displays the low, average and high values
of the signal. The number in the center below 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.
The Multipath reception level is measured in % (percents). The multipath detector measures
the amplitude uctuations of the signal. The FM signal is broadcasted with a xed level; therefore
the level uctuations will indicate degraded signal quality. At multipath conditions, large level
uctuations can be measured. To achieve better re-broadcast, install the antenna at the reception
point with the lowest multipath level.
IF Bandwidth – Shows the current IF lter bandwidth.

MPX Positive and MPX Negative – These bar graphs represent the positive and negative
deviation component of the MPX signal.
Pilot – Represents the deviation caused by Pilot tone injection. Our practice shows thatfor best
results the pilot deviation should be about 7.5kHz of the total deviation of the RF carrier.
RDS – Represents the deviation caused by RDS subcarrier. Our practice shows that for best
results the RDS deviation should be about 5kHz of the total deviation of the RF carrier.
Group 3. Audio related levels

Ultrasonic Noise – Indicates the MPX signal amplitudein the approximate bandwidth of 80
kHz – 150 kHz.
Stereo Blend – 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 – Audio disturbance effect is mostly present in the high frequencies. 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.
Soft Mute – 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.

Enter the Main Menu page and select the Graphs icon, press [OK] button to enter the menu.
Graph page represents the value of a measured signal over time. The X axis of the data plot area
represents the elapsed time in seconds. New peak value sample is added to the data graph every
125ms. Up to 20 seconds of measurement history is available for each signal. The newest sample
is on the right side of the graph. The current signal name and measurement unit are displayed in
the top left corner of the data plot.
A bar graph indicator, placed on the right part of the screen, is used to display the instantaneous
value of the selected signal. The low, average and high values of the measured signal are represented
in shaded color. The following signals can be selected:
From here you could set the Frequency, Attenuator Ant 2, RF Loss and PI Protection settings
of the Backup Station.
Tuner
These settings provide all the needed adjustments to the algorithm which DB7007 processes the
signal. From here the settings applied to the Frequency Step, De-emphasis, RDS Mode, Audio
Processing and Average and Peak (used for setting the indicators response times) could be applied.
Audio Processing considered – If set to Auto, the corresponding parameter will depend on
the quality of the received signal (RF Level, Multipath, and etc.). If any changes in the signal are
detected, the unit will automatically adjust to the correct values.

The composite multiplex signal, including the pilot tone, is generated through the build-in
Stereo generator. The stereo generator can operate in two modes - Stereo and Mono. In order to
overcome the noise of the treble frequencies the Emphasis can be set to Flat, 50μs or 70μs.
Injection levels
The MPX signal is a combination of Audio, Pilot and RDS Signal. This option allows you to
adjust the amount of each signal included in the MPX. The recommended and default values are:
0dB Audio gain, 7.5kHzPilot and 5.0kHzRDS.
MPX limiter
Settings> MPX
The regulatory authorities, in some countries, require the total MPX Power not to exceed
0dBr. Therefore, DB7007 has a built-in MPX ITU limiter that restrains the deviation below the
predened threshold. The default threshold is 0dBr.

The RF signal strength can vary by vast amounts. When the RF level is too low, the signal is
distorted and buzzing. In order for this effect to be avoided, a value for the signal quality as per the
RF level could be set, thus allowing the audio to be muted if the RF level is lower than the one set
(for the specied timeout).Once the audio is muted, the built-in silence detector will observe this
event. After the Audio Loss timeout expires, the DB7007 will switch to the back-up station, or the
next by priority backup source.
The function is available for both the Main and Backup stations. The desired values are applied
in the RF Loss Audio Mute and RF Loss Timeout.

UECP UDP Relay & UECP TCP Server
The unit can relay the received RDS as a UECP stream. There are two possible options:
Option 1 – via UDP, where the device sends the received RDS as UECP encoded UDP packets
unconditionally to the specied IP Address and Port. The receiver could be an RDS/RBDS Encoder
SmartGen, other RDS Encoder, or Monitoring Software.
Option 2 – via TCP. The unit has built in server and a Monitoring Software to receive the UECP
encoded RDS data could be connected to the unit.

The general purpose outputs settings are applied through this page. The Audio output and MPX
output sections allow setting the audio and MPX outputs, according to your needs.
Function, Type and Pulse time for each of the GPOs could be set individually. You can choose
between the following functions: Alarm GPO, RDS Lock, TA Flag and TP Flag. Type is used
for specifying of the active level. When an alarm is generated, the output can change the level to
Active High/Low or to generate High/Low Pulse.
NOTE: If the GPO’s function is not assigned as Alarm GPO and the selfsame is chosen as a
preferred alarm, notications will not be indicated, nevertheless one is being generated.

After collecting all the data, the DSP-based core compares the values measured with the
predened by the user threshold levels, for all the alarms monitored. In case that a parameter
is beyond limits, the device will initiate the sending of an alarm notication via the selected
communication path. All the alarm events are stored in the device’s log. It is essential that, if there
is a very short fault of the signal, with duration shorter than the alarm Trigger time, the device
would not trigger an alarm.
There are several Alarm Triggers for the following parameters: RF, MPX, Left/ Right Audio,
Pilot and RDS levels. An option for dening different limits for each of the parameters is present.
All these values, the Trigger time and the Release time have to be assigned separately for each of
the alarms.

When an observation event takes place, the alarm trigger’s state will refresh, if necessary. Should
we consider an instance when the alarm trigger is in Idle state, having in mind that an alarm is
not triggered immediately when a parameter level passes beyond threshold: If the parameter level
becomes stable, within thresholds, and the alarm Trigger time is not elapsed, then the alarm trigger
remains in Idle state. If the alarm Trigger time expires and the parameter level is still beyond
limits, the Alarm trigger would change its state to High/Low. This would result in predened
actions - alarm notications (E-mail, SMS, SNMP trap) and save a log record. The state will not
be immediately switched into Idle when the parameter stabilizes, within threshold levels, not up
until the alarm Release time is elapsed. Meanwhile, if the parameter crosses again any threshold,
the Alarm trigger will remain in active state. If the parameter remain within the threshold levels
and the alarm Release time expires, then the Alarm trigger would switch into Idle state and again
predened actions would be initiated.

The E-mail, SMS, SNMP trap Alarm Notications contain the following information - device’s
Alias, date and time of Alarm triggered, frequency and information about the Alarm activation/
deactivation. The basic signal parameters are also included.
Example for E-mal Notication:

The European Broadcasting Union (EBU) and its member countries originated the concept of
“Radio Data” transmission. The European RDS specication, 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 benets 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 Specication appropriate to his location either
the CENELEC EN50067 Specication for Europe or the United States NRSC Specication. Since
the Manual will deal with specic implication of RDS implemented with the Radio Explorer II, it
is assumed that the user is familiar with the RDS concept.

In order for a connection to be established the following setting should be applied:
1. FTP Server Settings
The built-in FTP Server has four important parameters that should be congured: Command
Port, Data Port, User name and Password. These parameters are to be used in the FTP client’s
connection conguration. 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 (https://lezilla-project.org). 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. TheFTP Server works in
Passive mode. Hence, the FTP Client should also be set in passive mode.
2. 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 congured. 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 conguration can be
found in the device.
