Radio Explorer I How to: How do I select the proper operation mode to be used during a campaign?
Depending on the observation purposes, Radio Explorer 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 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 I How to: Should I use an attenuator with Radio Explorer when I am close to a transmitter site?
Radio Explorer has a highly sensitive front end. When you are close to a transmitter site (less than 2 km, for example) we recommend an RF attenuator to be used with the product. Thus, better performance will be achieved and saturation of the input RF front end stage will be prevented/eliminated.
Radio Explorer I 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 I 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 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 I How to: My survey has too many points. How can I have a quick preview with fewer data points?
The number of measurement points can be reduced while reviewing the survey via Google Earth. Prior to visualizing the log file, the following settings via the Radio Explorer Software should be applied.
Go to Settings > Google Earth > Refine Settings section then apply the needed settings:
Enable Refine - Enables refine settings to be applied with Visualization in Google Earth.
Ignore Stacked Points with Distance Below - Points are defined as Stacked when length distance between them is below assigned. For example: If speed is quite low, then the result will be Stacked Points. Entering zero value will ignore Stacking despite Enable Refine option.
Split Path when Point-to-Point Distance is Above - Distance between two points is measured in length units as well in time units. In contrast to length distance, time distance defines Path Splits. Path Splits are ‘dead zones’ in the Path, where data cannot be obtained.
Ignore Points with Accuracy Above - With every point recorded there is corresponding accuracy value. Accuracy used here (as a term) is not coefficient, but deviation in length units. To eliminate inaccurate points specify value near to zero. Entering zero value will ignore Accuracy despite Enable Refine option.
Radio Explorer I How to: Can I export and view the collected with Radio Explorer data as CSV or TXT?
Radio Explorer stores the collected data in binary format (non readable). Thus, CSV and/or TXT formats are not available. The information could be exported and visualized into KMZ format using Radio Explorer Software.
