Radio Explorer III FM is DEVA Broadcasts's most advanced FM coverage survey tool yet. Making the most of their considerable expertise, vast know-how and years of experience, our engineers have developed a product that retains all of the best features of its predecessors, but also builds on them for even better monitoring performance. All of this makes for an advanced unit which conducts field surveys, evaluates FM broadcast band congestion and stores all important parameters in a log file, while the built-in FTP system allows you to download and manage the files through the DEVA Device Manager software.
The appeal of the Radio Explorer III FM lies not only in its reliability, but also in the second tuner it comes equipped with - an innovative approach in this range of products, guaranteeing a much higher level of effectiveness and precision. Used to collect RDS AF information and for running a PI scan, this tuner reduces both the time needed for monitoring a channel, and the distance between the map points in the log.
This device measures the RF level, MPX deviation, Left & Right Audio levels, RF field strength, as well as RDS and Pilot injection levels. All measurements are visualized on the easy-to-read OLED graphical display.
There are two campaign modes. The Radio Explorer III FM can be set to measure automatically one or multiple preselected frequencies (up to 50). It can also run an RDS PI / RBDS Call campaign, whereby up to 10 stations can be chosen. The device will automatically detect the used frequency. While the campaign is running, the chosen stations will be monitored; the Radio Explorer III FM will automatically switch between the variable frequencies during movement - just as the car radio of your listeners does.
When the campaign is over, the log files could be converted into KMZ format and visualized in Google Earth using the Windows software, which is supplied free of charge. The band scan mode guarantees real-time live visualization of either the FM band or a particular predefined part of it with down to 10 kHz resolution. The Radio Explorer III FM can be controlled through the built-in Web server, whereby a standard web browser can be used to monitor its status or to make some adjustments. iOS and Android devices are also supported. The Main Screen of the WEB Interface shows all mandatory parameters represented as LED bar graph readings.
Another way to manage the device is through the DEVA Device Manager Software, which is supplied free of charge – the easy-to-use interface allows for quick and easy connection to the unit. The dedicated module ensures managing of all the device’s logs and displays all the events in a handy manner.
The Radio Explorer III FM can also be controlled through the very intuitive user interface with an OLED screen, front panel navigational buttons and soft buttons, which ensure easy usage of the device’s built-in features.
At a great price, the Radio Explorer III FM is the ultimate mobile monitoring solution.
