Settings > Security > Front Panel
Then press OK and ENABLE the Access Control function. Set the preferred 4 digit password and access timeout.
Once the keyboard lock function is enabled, every attempt to use it will require a password:
ENTER PASSWORD:0***
Access will be denied upon false entry.
Radio Explorer II How to: How to unlock the front panel keyboard? I have forgotten the password / I have enabled the function unintentionally.
If the “Keyboard unlock” function has been activated by mistake, try to unlock it using the default password 01234. In order to deactivate the code protection, once the front panel menu is unlocked follow the menu path:
Menu > Settings > Security > Front Panel > Access control
and then select Disable.
If you do not manage to unlock the front panel with the default password, nevertheless whether it has been changed intentionally or not, the unit should be returned to its factory defaults in order for the password security to be disabled.

Radio Explorer II How to: My Logger/PI Campaign is not running. What might be the problem?
When the campaign settings are applied, you will have to specify not only the PI/CALL or Frequency, but also the Acquisition time / Campaign's start time delay. In order for a Campaign to be commenced, the device should be inactive for the specified time. It is very important, during the campaign the front panel navigational menu, WEB interface or SNMP not to be used; otherwise the campaign will not be properly performed.
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.
Radio Explorer II How to: How do I select the proper operation mode to be used during a campaign?
Depending on the observation purposes, Radio Explorer II utilizes two modes of operation:
- LOGGER MODE - used for on-field configuration and observation of one or multiple preselected frequencies (Up to 50);
- PI/CALL CAMPAIGN MODE – uses PI/CALL for preforming complete station surveys (Up to 10 stations can be chosen);
Radio Explorer II is a easy to use tool, designed to evaluate FM broadcast band congestion and to measure and store all important radio broadcast parameters in a Log file. Each mode measures all mandatory parameters and stores them in a Log file. Thus, the user always gets full information of the current condition of the chosen frequency/channel. Once the Log files are downloaded the unnecessary measurements could be filtered upon viewing.
Radio Explorer II How to: How do I start the campaign via the front panel navigational menu, i.e. Logger or PI Campaign?
In order to set up a campaign via the front panel menu, the following steps should be completed:
- Enter the Main Menu > Settings;
- Then select PI Campaign > PI Channel 1;
- Specify name of the PI and for 'Active' - select Antenna 1;
- Change the Acquisition time as per your preferences. We recommend setting it to 10 seconds;
- 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;
- Go to Settings > PI Campaign > PI Campaign Mode and as a parameter set 10 seconds. In order for a Campaign to be commenced the device should be inactive for the specified time.
The settings for Logger mode are analogous to PI Campaign. The menu path is
Settings > Logger > ...
Please 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.
Radio Explorer II How to: I have imported a campaign in Google Earth - visible path and almost no points. What could be the problem?
This problem is related to Google Earth. For further information, please take a look at the picture below or read Google Earth User Guide, section Time Slider.
Google Earth can visualize only a fraction of the entire time period. The points are there, but are not visualized (depicted) in Google Earth. When no points are selected the program will hide and reset the Time Slider.
We recommend you to animate the movement along the path or to extend the Time Slider at its full size as shown below.
NOTE: The time slider feature is available only in Google Earth 5 and later.
Radio Explorer II How to: I cannot receive any GPS information in the GPS menu of my Radio Explorer II, what could be the problem?
Sometimes the GPS receiver needs several minutes to initialize (update) its satellite table. That could be the reason why satellites are not indicated as soon as you have connected the antenna to your receiver. Also, select a suitable location for installation that allows routing of the antenna cable to the Radio Explorer II and also provides a clear view of the sky for a good satellite reception.
Please note that the GPS works at his best outside, not inside buildings. When you are in narrow streets, without clear view of the sky, good satellite reception will not be received. Also, check your GPS antenna cable, to make sure it hasn’t been damaged by closing a door.
Radio Explorer II How to: What are the units of the GPS Longitude and GPS Latitude shown in the campaign result file?
Decimal degrees (°) - Latitude and Longitude are how your site location is defined on the surface of the earth. Latitude is used to express how far north or south you are, relative to the equator. If you are on the equator your latitude is zero. If you are near the North Pole your latitude is nearly 90° north. If you are near the South Pole your latitude is almost 90° south.
Longitude shows your location in an east-west direction, relative to the Greenwich meridian. Places to the east of Greenwich (such as Middle East, India and Japan) have longitude angles up to 180° east. Places to the west of Greenwich (such as the Atlantic and North and South America) have angles up to 180° west. For inputting to the satellite dish pointing calculator, longitude west figures need to be input as negative numbers.
Radio Explorer II How to: I could not hear the audible notification when GPS is not fixed. Why?
This function only works when GPS Fix has been established and the GPS signal has been lost afterwards. If the option is constantly enabled, the alarm will be audible on every power-up, especially when the device is used indoors.
Radio Explorer II How to: My survey has too many points. How can I have a quick preview with fewer data points?
Radio Explorer II stores data points at the highest possible rate to provide the highest possible level of details. The number of measurement points can be reduced while reviewing the survey via the DEVA Device Manager Software. In the Log viewer > GPS tab > Refine section mark the “Enable Refine” checkbox and adjust the "Minimum Stack Distance" option. If the distance between two points is less than the one that is set, these two points will be converted into one. Please note that this option will not only reduce the points but will also change the signal path formation.
Radio Explorer II How to: Can I get an RF field strength measurement along with the RF level measurement?
Yes, you can. In order for this to happen, an antenna calibration should be provided. Such calibration can be applied via the front panel, DEVA Device Manager Software and WEB Interface. Following is an explanation on how this setting can be applied via the WEB Interface:
- Connect the device via the WEB interface;
- Go to Settings > Tuner section;
- Locate the Antenna calibration subsection;
- Define the cable loss, frequencies and their corresponding factors. Up to 5 frequency/factor pairs can be assigned.
