Tx B lists
(tuning frequency: f Tx B)
f Tx D f Tx B
Note that the frequency of transmitter C is not included
in the list, since the latter’s coverage area does not
overlap with that of transmitter A
AF1 AF2 AF3
f Tx D f Tx B f Tx E
f Tx B f Tx D f Tx D
Tx D lists
(tuning frequency: f Tx D)
f Tx E
Coverage area D partially overlaps that of both
transmitters B and E, and thus it is recommended to
load the lists for both adjacent transmitters. Be careful
to list all frequencies above the tuning frequency in
ascending order.
AF1 AF2
f Tx E f Tx D
Tx E lists
(tuning frequency: f Tx E)
f Tx D f Tx E
Note that the frequency of transmitter B has not been
included in the list, since its coverage area does not
overlap with that of transmitter E.
METHOD B
As mentioned earlier, Method B is used with high numbers of alternative frequencies and/or when the transmitter
also has frequencies that broadcast different radio program at various times of day (splitting, local programming,
etc.).
In the latter instance, the mobile receiver should check whether the AF is broadcasting the same content before
selecting another frequency.
Each list begins with the tuning frequency (for which the list is valid) and then contains up to 12 pairs of
frequencies in sequence, each containing the tuning frequency and an alternate. If there are more than 12
possible alternative frequencies, the list continues in other lists in the same manner.
The order of the frequencies in each pair follow the rules below:
- If the order is increasing, the alternative frequency broadcasts the same programming as the tuning
frequency.
- If the order is decreasing, the two frequencies have different programming.
Returning to the example of transmitters B, D and E in the previous paragraph (in which the coverage areas of D
and E do not overlap), two more lists will be assigned to transmitter B, sorted according to the above criteria to
take into account any different programming by some of the AFs.
