The Band Scanner GPS enables you to evaluate FM broadcast band congestion and to log stations’ identification parameters. This device is a Google Earth compatible tool with a built-in GPS Receiver generating a display of the collected FM Radio measurements. The Log file can be exported as a .kmz file or a transitional format and saved for future analysis.

Pocket-sized and USB-powered, the Band Scanner GPS is the perfect device for field work. This unit can measure RF level, MPX deviation, Left & Right Audio levels, RDS and Pilot injection levels. The measurement results can be easily displayed in Google Earth. The band scan range is from 87 to 108 MHz. The supplied - free of charge - Windows software sweeps the receiver across the FM band, logging every carrier and generating a spectrum display of carrier level vs. frequency. It then analyzes each carrier and creates a station list.

This is a tool to evaluate FM broadcast band congestion and to log station identification parameters."Band Scanner GPS" is a Google Earth compatible tool for visualization of collected FM Radio measurements. When running a campaign with the "Band Scanner GPS", the results will be saved in a Log file. "Band Scanner GPS" can then convert this file into KMZ format and the results could be viewed on Google Earth. The Log file can be exported also as transitional format for future analysis or to kept in record. The "Band Scanner GPS" can measure RF level, MPX deviation, Left & Right Audio levels, RDS and Pilot injection levels. The system is powered by the USB port of any Windows PC. Supplied free of charge Windows software sweeps the receiver across the FM band, logging every carrier and generating a spectrum display of carrier level vs. frequency. It then analyzes each carrier and creates a station list. Stations with an RDS presence are further refined to show all the radio data groups that were being transmitted. Its interface is like a portable radio's: It may be tuned manually through the receiver screen or by double-clicking a point on the spectrum plot or an entry on the station list. Spectrum plots may be saved as jpg or bmp files. The RDS data error level is graphed in a separate window on the receiver screen. The program can be monitored with headphones plugged into a standard 1/8" jack.

• What does (same) and (reg.) mean in the RDS AF List?
  This is a citation from US RBDS Standard/EN 50067 standard:
  Method B AF coding is used where it is required to indicate frequencies that belong to different regions, which may carry different programs.
  For the transmission of the frequency pairs within one block the following convention is used:
  

  • They are generally transmitted in ascending order, e.g. 89.3 - 99.5 or 99.5 - 101.8 F1 < F2
  • In special cases they are transmitted in descending order, if they belong to different regions, or carry from time to time different programs, e.g. 99.5 - 90.6 or 100.7 - 99.5 F1 > F2

  In both of the above examples 99.5 MHz is the tuning frequency.
  
  Examples of a AF method B coding:
  

  F1	F2	Commentary
  #11	89.3	Total number (11) of frequencies for tuning frequency (89.3)
  89.3	99.5	F2 > F1 hence 99.5 is an AF of tuned frequency 89.3, and it is the same program
  89.3	101.7	F2 > F1 hence 101.7 is an AF of tuned frequency 89.3, and it is the same program
  88.8	89.3	F2 > F1 hence 88.8 is an AF of tuned frequency 89.3, and it is the same program
  102.6	89.3	F2 < F1 hence 102.6 is an AF of a regional variant of tuned frequency 89.3
  89.3	89.0	F2 < F1 hence 89.0 is an AF of a regional variant of tuned frequency 89.3
  #9	99.5	Total number (9) of frequencies for tuning frequency (99.5)
  89.3	99.5	F2 > F1 hence 89.3 is an AF of tuned frequency 99.5, and it is the same program
  99.5	100.9	F2 > F1 hence 100.9 is an AF of tuned frequency 99.5, and it is the same program
  104.8	99.5	F2 < F1 hence 104.8 is an AF of a regional variant of tuned frequency 99.5
  99.5	89.1	F2 < F1 hence 89.1 is an AF of a regional variant of tuned frequency 99.5
• Why when running a campaign, the PI tracking cannot be maintained?
  You need to make sure first that the Signal Quality has not became very poor. Bad signal quality leads to erroneous RDS reception and then to incorrect Alternative Frequencies (AF) lists. On the other hand, when there are long AF lists in such 'bad' environment, Band Scanner GPS lacks the speed to observe all the AFs correctly, which results in wrong/missing PIs. Also, multiple tasks, together with poor signal reception produce unusual gaps. We recommend that you use RF antenna (installed outside the vehicle) and isolate the problematic station and run campaign only with it. Driving speed is also a factor.
• Why upon installation of the software, the USB green LED on the unit is flashing rapidly?
  Green flashing LED indicates that Band Scanner GPS has no drivers installed. With a normal installation, the driver will be located here: My Computer/Local Disk (C:)/Program Files/Band Scanner GPS/Drivers. Drivers can be found on the supplied CD also, in the 'Drivers' folder. Driver Installation details are described in DEVA User Manuals, chapter 'Installing the Software'.
• Why there is a very slow frequency change when running a campaign?
  Running a campaign depends on many factors. In case of a very slow frequency change, or no change at all, the reasons could be several:
  

  • Bad signal reception - if switch to a frequency with bad signal reception is made, it is obviously a dead end one - due to errors, no information could be collected for a switch to another frequency to take place.
  • Too long AF lists (with a short listen time it could not acquire AF list at all) – After observing all frequencies from the list, one that best suits your purposes should be chosen. Bad Signal Reception and PI tracking are yet another factors to influence the frequency change. For more detailed investigation into the possible reasons, you need to know the changeover points (AF lists, PIs, etc.) and to observe the campaign file.
• How can I reset the data acquisition?
  Press the "SET" button. Whenever setting the frequency (same or not) it will clear all of the acquisitions.
