Jog Wheel Editing Procedure

DRTS sets the interval that the Radio Text message
is retransmitted (refreshed) to listeners’ radios. The
setting has a nominal range of 1 to 9, similar to the
DPSS setting.
Push the jog wheel to set the DRTS (RadioText re-
fresh) rate. A the default setting of 3 should be ade-
quate for static messaging, or a 6 or 7 for RT+ appli-
cations. Radio Text transmission can be turned off
entirely with a DRTS setting of 0 (zero). If your sta-
tion elects not to send a RadioText message at all,
setting DRTS to 0 will maximize throughput of other
RDS functions.

The PI code is the station’s ‘digital address’ and is
unique to each station. The PI code is a 4-
character hexadecimal code, which is calculated
from call letters in the US and Canada but is as-
signed by the local Broadcasting Authority in other
parts of the world.
When the 730 Encoder is in the RDS mode, only
the top line of the Menu 12 screen will be active.
This is where the hex code is entered.
For North American broadcasters (RBDS mode),
the 730 has a built-in utility to calculate the PI code
from station call letters automatically. The call sign
may be entered directly in the lower line of the LCD
screen after passing through the PI field.
Push the jog wheel to enter the PI: area. The blinking
cursor can be set to any hexadecimal value between
0 (zero) and F on the upper line of the LCD. The hex
code will always contain just the numerals 0 through
9 and letters A through F, and will consist of 4 charac-
ters.
To enter North American call letters in the RBDS
mode, push the jog wheel repeatedly until it enters
the CALL-LETTERS: area. Note that the first letter is
restricted to a C, a K or a W. Enter the three- or four-
letter call sign. (A blank for a 3-letter call follows ‘Z’.)
The conversion utility automatically pops-up the
proper hex value in the PI: area on the upper line of
the LCD.
13
PTY, or Program Type, indicates your station’s pro-
gramming format. This allows RDS radios to seek a
particular genre of programming automatically. PTY
codes come from a list appropriate to RBDS (North
America) or RDS (Rest of the World) Standards. A
listing of these PTY codes is shown in the Appen-
dix. The proper list is automatically selected when
the 730 Encoder is initially set for RDS or RBDS
operation as described in the first part of this sec-
tion.
Push the jog wheel to enter the PTY code appropriate
to your station. As the jog wheel is rotated, the 730
displays the format description on the lower line of the
LCD. When the proper format is displayed, press the
jog wheel again to set PTY.
Refer to the list in the Appendix; some additional
information appears on Page 39.
14
PTYN is an 8-character identifier that further defines
the PTY listing. PTYN is not used in the RDS
‘search’ mode, but once a station is tuned-in the
PTYN designation may be displayed on some re-
ceivers. The PTYN function is shown either
Enabled or Disabled.
Push and turn the jog wheel to enter up to 8 charac-
ters that will help identify a program type and enable
the PTYN function. To clear the entry and disable the
PTYN feature, enter spaces for all characters.
15
The Music/Speech switch is one of the ‘flags’ that
supposedly helps the receiver understand what it is
tuned to. Further information may be found on
Pages 10 and 39.
Push the jog wheel and rotate it to select 0 or 1, de-
pending on your station being talk-only or having
music programming, respectively. Push again to set
the flag.
16
The Decoder Information flag is another obscure
feature of the original RDS Standard (see Pages 10
and 39).
Push the jog wheel and rotate it to select 0 or 1, de-
pending on your station being monaural or stereo,
respectively. Push again to set.
17
TP (Traffic Program) identifies your station as one
that supplies routine traffic announcements as part
of the station’s normal programming. This mode
must be enabled to use the TA function (Menu 18).
See Page 49 for further explanation and cautions.
Push the jog wheel and select 1 (or 0), depending on
whether your station DOES (or does NOT) broadcast
regular traffic announcements. Push the jog wheel to
accept the selection and to verify the setting on the
second line of the LCD.
