To guarantee the reliability of the system it is necessary to set it up in the best conditions, following the guidelines
presented below.
It is understood that the equipment is installed following the operating recommendations as stated in the user manual
regarding the environment, the electrical network and the communication network.

1.3.3.1. Reception system and monitoring site
The AUDEMAT FM Monitor could be installed at a transmitter site or at a dedicated monitoring site. In the first case,
the RF signal is obtained from a probe attached to the RF output of the transmitter or of the cavity filter. In this
situation, the RF levels are normally very high so it is necessary to put adequate attenuation between the source and
the monitoring equipment, reducing the RF level within the AUDEMAT FM Monitor’s acceptable range (20-95 dBµV).
When monitoring off-air signals, the RF is delivered from an external antenna linked to the unit by a coaxial cable.
There are different types of outdoor antennas: their selection and installation is one of the most important aspects of
the monitoring site.
The most common types of FM antennas are:
-Omni-directional antenna
-Unidirectional dipole
-Multi-element array antenna.
Omni-directional antennas normally have low gain, and the lack of any significant directionality does not make them
really suitable for continuous monitoring. The average noise level detected by this type of antennas is higher than in
directional antennas, since the reception lobe is almost 360°, exacerbating the effects of unwanted signals such as
multipath interference.
Unidirectional dipole and multi-element array antennas are characterized by a significant directivity and a greater gain
(up to 7 dB for a log antenna), and so are more suited for monitoring purposes. The beamwidth decreases with the
increase in the number of elements so high levels of selectivity can be reached, but conversely a very narrow
beamwidth could make pointing the antenna in the direction of the transmitter difficult.
The reception antenna used at a monitoring site should be a professional FM reception device, able to guarantee
consistent performance over time and avoid degradation of the
reception due to corrosion, etc.
Moreover, it is strongly advised to use antennas calibrated for FM
band frequencies (ie. not broadband) to be sure that out of band
signals (TV or civil application transmissions) do not interfere with
the monitoring system. This could indeed happen if a consumer
wide band antenna is used.
The outdoor antenna should normally be installed taking into
account the surrounding environment, in terms of obstacles and
objects or buildings close by. To guarantee a minimum protection
against multipath interferance; a distance of about 3 meters (1
wavelength at 98 MHz) is recommended between the antenna
and any surrounding objects. For example, a directional antenna
installed too close to a wall will receive signal reflections from the
wall, which can easily affect monitoring capabilities.
To set a monitoring site it is necessary to:
a. Know the distance and direction of transmitter sites relative to the position of the monitoring site
b. Make a measurement campaign around the chosen site, verifying the stability and the average level of the RF
field.
c. Determine the list of the channels to be monitored and verify they respect the minimum recommendations in
terms of signal/noise ratio, RF protection ratio (adjacent and iso-frequency signals), modulation power, etc.
Typically each monitoring site keeps track of signals from one single transmitter site, with one or more programs. A
single directional antenna should be used to receive the signals as stated in the preceding paragraphs.
In case more than one transmitter site is to be monitored, it is recommended to use a separate directional antenna,
aimed at each of the sites and use a coupler to combine the signals before connecting to the splitter. That way, it is
possible to avoid using an omnidirectional antenna and keep the selectivity and sensitivity typical of a directional
antenna.

1.3.3.2. Evaluation of the FM Band
The first thing to do after having installed the AUDEMAT FM Monitor is to run an identification scan to verify (if not
done before with a spectrum analyzer) that the antenna system and all the cable connections to the AUDEMAT FM
Monitor are functional and to check the average RF level detected.
Fig. 1 –Identification scan of the FM Band (100 kHz step) at a monitoring site
This first scan identifies any anomalies or critical monitoring conditions. The most common situations are:
a. Average RF field too high: the FM receivers of the AUDEMAT FM Monitor are capable of detecting signals
between 20 and 95 dBµV, but for monitoring purposes the nominal level should be kept at lower values, to
guarantee the correct decoding of sub-carriers information and avoid saturation conditions induced by strong
fields.
b. The energy distribution in the FM band depends on the RF level of all the signals found during the scan; a
homogeneous band (i.e. all carriers have approximately the same level –see Figure 1) is a good base for
monitoring, as there is no energy concentration on any specific frequency, thus there is no large RF
differential between two monitored stations.
The recommended monitoring conditions are:
1. RF level of controlled stations between 30 and 65 dBµV
2. Frequency distance between 2 monitored stations at least 300 kHz
3. Basic noise level under 10-15 dBµV
If the RF level of the monitored stations or the basic noise level is higher than the suggested values, the use of a
coaxial passive attenuator is recommended: this device will decrease the overall RF level and will also reduce the basic
level of noise that can affect sub-carrier decoding.
If there is one single very strong carrier (for instance when a monitoring site is very close to a local transmitter), the
use of a tuned notch filter is suggested. Typically, this type of filter applies an attenuation only on the frequency on
which it is tuned, leaving the surrounding RF field unaltered. An example of notch frequency response is the following:

Page 11

Tel [phone] –[e-mail] –www.worldcastsystems.com
Fig. 2 –Frequency response of a notch filter tuned at 101 MHz
If the monitoring site is near a TV (Analog or Digital) or Civil VHF transmission site, it is important to protect the
equipment from any possible interference generated by the other transmitters. The first filter is the reception
antenna that, if chosen as stated, could already reject out of band signals; however, if the carriers are very strong
those signals could interfere with the AUDEMAT FM Monitor’s receivers.
In these cases, it is strongly recommended to install, between the 3 way splitter and the antenna, a coaxial low-pass
filter to reject all frequencies greater than 108 MHz, thus improving the monitoring ability of the equipment.
An example of commercial filter is the Mini-Circuits SLP-100+ filter:
This filter rejects all frequencies over 100 MHz but with only a little insertion loss up to 110 MHz, is useful for the FM
band. In the attenuation graph above, the attenuation characteristics are visible,,peaking at 40 dB and more at
frequencies of 175 MHz and higher.
1.3.3.3. Monitoring
After the evaluation of the FM band, it is time to start the monitoring activity. ‘Controlling’a radio station does not
mean monitoring the transmitter parameters, its product in terms of RF level, presence or lack of subcarriers,
modulation, etc.
Environmental conditions (snow, temperature variations, storms and heavy rain) between transmitter and receiving
antenna could impact the monitoring abilities as they change the reception conditions so it is important to consider
those aspects when starting any radio monitoring.
It is strongly recommended to start the activity of the equipment with a period of measurements without alarms to be
able to observe the behavior of the controlled signals over a sufficiently large time window to determine the correct
alarm thresholds to be applied.
A good procedure is to first configure wide alarm thresholds and to narrow them down after some time, based on the
trends of the signals during the observation period. This strategy is also useful to determine if any of the characteristic
parameters of the signal (subcarriers, audio, …) is unstable due to saturation or reception problems: it is useless to

Tel [phone] –[e-mail] –www.worldcastsystems.com
monitor an unstable RDS signal which would generate many alarms when it is clear the reception conditions do not
permit RDS detection (basic noise too high, interference, etc).
The same principle should be applied to the alarms timeouts, beginning with a relatively long time between the error
state and the alarm transmission and decreasing it after several hours/days of observation.
Some basic monitoring parameters suggested for the configuration of the AUDEMAT FM Monitor:
RF level RF high 61 dBµV timeout 30 sec
RF low 1 49 dBµV timeout 30 sec
RF low 2 45 dBµV timeout 30 sec
AF level AF high 3 dBr timeout 1:15 min
AF low -35 dBr timeout 3:00 minutes
MPX level MPX low 0 kHz timeout 120 sec
MPX high 85 kHz timeout 120 sec
Concerning the configuration of timeouts on the different alarms, it should be considered that this time is also
influenced by the number of channels configured on the equipment: in basic monitoring (without extended RDS), each
channel is scanned for 1 second before the receiver proceeds to the next one. As an example, if 40 channels are
monitored (either in “active monitoring” or “measure without alarm”), the maximum wait time between the
AUDEMAT FM Monitor alarm detection and transmission is the configured timeout + one complete monitoring cycle
(for 40 channels on basic monitoring, 40 seconds).
The extended RDS monitoring is a separate process and takes 1.5 seconds per channel. Extended RDS data is collected
in a dedicated buffer and it is based on this data that the different alarm conditions are detected. To guarantee
correct detection of all RDS groups, it is necessary to give this process an adequate monitoring time, typically around
10 minutes.
The auto-configuration scan is described in sections 7.1 and 9.2; this function makes it possible to view all carriers
present in the band.
These prerequisites should be taken into account so as to give the essential components (CPU and receiver) the best
operating conditions. These components are sensitive, and extreme conditions greatly decrease their reliability and

3.2. Connecting to the network
Connect the Ethernet cable (A) from the unit’s primary
interface to your PC *, or to a router or a switch
* With a direct connection, you will need to set an IP
address on your PC in the same range as the IP address you
just set using the front panel application, so both are
compatible. Example: if the Monitor’s IP address is
192.168.0.7, the PC IP address must be in the 192.168.0.xx range. The
procedure varies depending on your operating system.
With Windows 2000 or Windows XP, go to:
Control panel / Network connection.
Local Area Connection / Properties
Click on Internet Protocol (TCP/IP) in the list then
on Properties.
Add the IP address and the sub-net mask. (for example
192.168.0.56 / Netmask 255.255.0.0).
With Windows Vista or Windows 7, go to:
Control panel / Network and Internet / Network and Sharing
Center.
Click on “View Status” for your local area connection, and on
Properties
Click on Internet Protocol 4, then on Properties.
Add the IP address and the sub-net mask (for example 192.168.0.56 / Netmask 255.255.0.0).
