8%. The factory-default value of 5% is typical for reliable RDS
reception by most consumer receivers. Again, do not turn RDS
On yet.
RDS Regen
Mode
This submenu presents four
choices for encoding the
RDS data subcarrier. These
choices are explained in the
paragraphs that follow.
Re-encode RDS simply regenerates an d re-transmits the incom-
ing RDS data in its original form. The 57kHz subcarrier is re-
generated and remodulated, but this is a true RDS data pass-
through. What comes in goes right back out again (except for
noise and jitter!).
Re-encode RDS with new PI Code
re-transmits all the original RDS
data, just like the first option, but with the sole exception of
the PI code: the station’s ‘digital address.’
Every FM broadcast signal source (transmitter site) is supposed
to have a separate and unique PI code. Adhering to the letter of
this operating practice requires even rebroadcast translators to
have their own digital identity, despite the fact that they are
simply relaying a broadcast in real time on another frequency.
When the Re-encode RDS with new PI Code option is selected, the
AARON 650 strips the PI code from the incoming RDS data and
substitutes the one entered by the user in the RDS Data menu
(see next margin heading).
Song title and artist information is an example of ‘dynamic’
RDS messaging, and must be tied-in to station automation or
even a third-party data consolidator. Choosing the Built-in RDS
option removes the entire incoming data stream and replaces it
with ‘static’ RDS data that is entered manually in the RDS Data
menu.
In the RDS PS field, this static (fixed) messaging can contain up
to 128 characters. Any entry in excess of 8 characters is auto-
matically parsed and scrolled across the faceplate of listeners’
radios. Radio Text is a separate message field of up to 64 char-
acters.
Static messaging can be updated remotely through the AARON
650 Web interface, but still requires manual data entry. It can-
not be programmed by station automation, thus relegating stat-
ic messages to station and program promos.
Built-in RDS with Internet Time
is identical to the mode just dis-
cussed, except that the AARON 650 inserts current clock-time
derived from the Internet. For this service to function, howev-
er, the timekeeping function must first be set up separately un-
der: Main Menu / Setup / Network / Time .
