Important note: Factory default PI value is FFFF and it's needed to change it as
soon as possible to avoid the situation that two different stations with common
area of coverage have the same PI. For each station in the same location the
unique PI must be assigned. Stations that carry different program must be
unambiguously identified by the last two PI digits. In other case they are
recognized as one station by car radios, regardless of any other service
settings. If
the broadcaster hasn't received the 4-digit PI from regulatory office, he must
choose such number that is not in conflict with other stations in the location. Set
your final PI as soon as possible!
6.1.2 PS (Program Service name)
The PS name is max. 8 character long radio station name that will be shown
most of the time on the radio display.
6.1.3 PTY (Program Type)
The PTY code defines the type of the programme broadcast within 31
possibilities.
This code could be used for search tuning.
6.1.4 TP (Traffic Program)
This is a flag to indicate that the tuned program carries traffic announcements.
The
TP flag should only be set on programs which dynamically switch on the TA
identification during traffic announcements. The flag shall be taken into account
during automatic search tuning.
6.1.5 MS (Music/Speech)
This is a two-state signal to provide information on whether music or speech is
being broadcast. The signal would permit receivers to be equipped with two
separate volume controls, one for music and one for speech, so that the
listener
could adjust the balance between them to suit his individual listening habits.
6.1.6 AF (Alternative Frequencies)
The Alternative Frequencies are used to tell receivers what frequencies they
can receive the radio station on. This facility is particularly useful in the case of
car and portable radios. For this to work, each transmitter must have RDS with
the same PI code.
Important note: If second PI digit is set to zero (x0xx), this indicates that the
station has only one transmitter and the AF list is ignored on most receivers.
