Band Scanner Pro – FM Band Spectrum & Mod Analyzer, RDS/RBDS Decoder-Reader

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

Green flashing LED indicates that Band Scanner Pro has no drivers installed. With a normal installation, the driver will be located here: My Computer/Local Disk (C:)/Program Files/Band Scanner Pro/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'.

Press the "SET" button. Whenever setting the frequency (same or not) it will clear all of the acquisitions.
