27 THE ‘STATIC’ RDS / RBDS

Double click the ‘Static RDS’ icon:

27.1 SYNCHRONIZE INTERNAL CLOCK AND ENABLE ‘CT’ SERVICE

Barracuda features an internal clock and calendar, that are used as reference either for PS, RT e PTY/PIN service

scheduling, or for CT (Clock Time) service.

Real Time Clock panel allows the user to adjust the Target current time and date. If enabled (see CT On/Off button), this

RDS feature can allow every receiver to automatically set its internal clock. Current time and date of Yr Pc is

permanently shown at the center of the Panel. You can select two different time references for the Barracuda: the PC

clock or an User-defined time. Selection is done through the dialog Box below the clock display:

COMPUTER CLOCK sinchronizes Barracuda internal clock to

actual

Pc clock

USER SETTINGS allows the user to set a specific tame and date through the User Settings mask at the left of the panel

(see picture below). NOTE: in application of the relevant CCIR Recommendations, broadcast time and date codes

should use Coordinated Universal Time (UTC) and Modified Julian Day (MJD). The listener, however, will not use this

information directly and the conversion to local time time and date will be made in the receiver’s circuitry.

A coded local time-difference, expressed in multiples of half-hours can be appended to the User time and date codes

(see Local Time Offset options) Click ‘Synchronize’ to update Target time to the selected time reference. Make sure of

the current Pc time prior to upgrade the Barracuda’ clock.

CT information is carried in the 4A Group. That Group is

automatically managed by the Barracuda and is NOT user-

enabled.
