Important Note About Antenna Cabling.
75
Ω
coaxial antenna cable will provide better shielding than the
supplied 300
Ω
FM cable, which will reduce noise and
interference on the tuner. A better antenna, oriented toward the
signal source (i.e. broadcast towers) will also improve signal
reception. Connecting the GND connection to the earth on the
PA amplifier will also reduce electrostatic noise, especially for
AM reception.
About RDS Functions - Radio Data System.
Allows a tuner
ʼ
s LCD screen to display text information being
transmitted by FM analogue radio stations. RDS technology is
becoming more prevalent in Australia. RDS Codes: PTY –
Program Type (ie Station format or music genre); PS - Station
Name or ID; DATE or CLOCK
TIME; TEXT - Song Title, Artist,
Station slogan, traffic updates etc. If the FM radio station in
question has not activated and/or is not broadcasting RDS data,
then the RDS feature will show nothing, no scrolling text, time,
station name etc.
