RDS APPLICATIONS SUPPORTED
PI (Program Identification) 730 software automatically
calculates PI codes for the US and Canada
PS (Program Service Name) An 8-character station 'street name' or 128-character scrolling message (song info, promos, advertising, etc.)
PTY (Program Type) Identifies your station’s format
TP (Traffic Program) A data flag identifying stations that routinely include traffic bulletins in their programming
TA (Travel Announcement) The TA data flag is broadcast only during a critical traffic or other emergency
announcement. Some RDS radios automatically retune to a station airing such announcements, and TA broadcasts may even override CD or MP3 entertainment
RT (RadioText) A 64-character block of plain-text messaging that can be called-up on the faceplate of some
RDS radios. RadioText is separate from, and in addition to, scrolling-PS messages
AF (Alternative Frequencies) Up to 25 frequency entries for rebroadcast 'translators.'
DI (Decoder Information) The mono/stereo data flag
M/S (Music/Speech Switch) The mixed-music or speech-only data flag
RAW (Raw Data Entry) The 730 accepts ‘Free Format Group’ commands to facilitate custom RDS applications
Runs on any Windows® PC for either USB or serial (COM) port operation. The software is intuitive, self-guiding and
contains numerous pop-up and other Help files.
Loop-Through: The RDS subcarrier is internally mixed with the MPX input and the combined signal appears at the encoder output at unity gain
Sidechain: In this mode just the RDS subcarrier appearsat the encoder output. The monitored MPX or 19kHz sync
is only bridged to synchronize the 57kHz RDS subcarrier with the stereo pilot
PILOT OR MPX INPUT
An unbalanced, bridging (BNC) input accepts either the composite/multiplex (MPX) signal or 19kHz TTL-level pilot
sync from the stereo generator. The 720 reverts to an internal crystal timebase for monaural transmissions.
RDS OR MPX OUTPUT
An unbalanced, 75-ohm (BNC) output feeds a wideband .input of the FM exciter.
RDS INJECTION LEVEL
Subcarrier level is continuously adjustable from the front panel from zero to 3V p-p. The LCD screen gives both bargraph and voltage readouts.
SERIAL DATA PORT
A rear-panel RS-232 port (DB-9) accepts static encoder programming and dynamic messaging from station automation. The 720 accommodates all common data rates between 1200 and 115, 200 baud. 720 software features an automatic port and data rate ID utility to simplify initial connection and setup.
A front-panel USB port gives quick and easy access for encoder setup. All static messaging may be quickly set with a laptop PC.
The temporary TA flag is set either by a software command or with a contact closure through a rear-panel terminal strip. A TA-timeout utility prevents TA flag violations.
