Off (Composite Pass-Through)
. You must base
your decision as which mode to use on the overall quality of
the re-transmitted program signal. This means that you must
monitor the translator frequency off-air, as the front-panel
headphone jack will not reflect the difference between modes.
Alternatively, if you have a means of decoding and monitoring
the composite/MPX feed at the exciter input, this allows an
equivalent A/B comparison.
The full advantage of regeneration will not be realized, howev-
er, until Reception Tools setting have been optimized (Page 29).
STEREO-REGEN MODE OPTIONS
Stereo-Regen
Mode Defaults
The stereo regeneration mode offers operating options that
need to be considered when this mode is selected. Not only do
the built-in Reception Tools need to be optimized for best per-
formance, but additional options deal with stereo vs. monaural
transmission and RDS encoding. Factory defaults are stereo
transmission with a typical 9% pilot injection, and the RDS sub-
carrier turned off. These options, discussed next, may be
changed under the Stereo Regen menu.
Monaural
Operation
Under the
Stereo Regen
menu, select Pilot On/Off & In-
jection
. The screen that pops
up will allow you to control
the 19kHz stereo pilot in the
stereo regen mode. The factory default values of On and 9% are
typical for normal everyday operation. Turning the pilot
Off
for
mono automatically takes the injection to zero (despite the
number showing under the adjustment slider), and turns off
the 38kHz suppressed-carrier DSB stereo difference subcarrier
as well.
STEREO-REGEN MODE RDS OPTIONS
From the Main Menu, navi-
gate to
Stereo Regen / RDS En-
coding . Here you will see five
submenus, each offering var-
ious programming options
for the RDS data stream.
RDS On/Off
and Subcarrier
Injection
NOTE: Do not turn RDS On until all pertinent option fields
have been programmed as described in this subsection!
Highlight the first submenu,
RDS On/Off & Injection and push the
knob. The factory default for RDS transmission in the stereo
regen mode is Off . This menu allows you to turn the 57kHz
subcarrier
On
and set
Injection
at any value between 3% and
