3.5.2 B Method
This method is indicated if the issuer has more than 25 alternative frequencies or if a multi-regional or
national broadcaster diffuses differentiated regional programs at different times of the day.
In this method, the number of busy lists is equal to the number of repeaters present, so the frequency of
each repeater and all its possible alternatives is spread.
Each alternate frequency is always transmitted in pairs with the capolist frequency to which it belongs;
the order of the capolist-alternate pair defines whether that particular alternative frequency is a regional
variation of the capolist frequency.
Each list begins with the capolist frequency, followed by 12 capolist-alternative pairs; If the alternate
frequencies were greater than 12 for the same leader, two or more lists may be used.
If instead the same headlamp frequency is used more than once in the network, the alternative frequency
list will be separated by a list with a different header so that the receiver does not erroneously associate
the alternate frequencies to the same header.
Leader-alternate pairs are generally transmitted in ascending order if the alternate frequency transmits
at any time of the day the same program as the capolist frequency.
The decreasing order is instead used to indicate that the alternative frequency is a regional variant of the
leader, so at different times of the day, it could transmit a different programming.
To simplify the programming of a list B, set as the first frequency the capolist frequency, and follow all
the alternate frequencies (max. 12).
Right-click on the grid and select the "Build B list" function.
If you want to add a new alternate frequency at this point, put it in the queue to the list just populated
and select the "Build B list" function again.
Enter the master frequency like AF1 and all other frequencies in queue to it.
