The MicroRDS Encoder is a professional
full-featured FM broadcast RDS encoder module that supports all basic RDS services at
unmatched acquisition costs. It's up to you if you use this RDS encoder with one
transistor FM bug or a 10 kW transmitter. It provides your station all common RDS
services: Program service name, dynamic PS, Radiotext, Program Type identification,
Traffic Program, Traffic Announcement and Music/Speech flags, Alternative Frequencies list
and some more. This unit is ideal for embedding into existing FM transmitter as well as
for development and hobby purposes.
The design is based on the MRDS1322 chip. Direct digital
synthesis of the RDS signal, equipped with pilot input for optional synchronization.

Supports both stereo and mono transmission
& documentation download
RDS services directly supported:
PS (Program Service), PI
(Program Identification), PTY (Program Type), TP
(Traffic Program), TA (Traffic Announcement), DI
(Decoder Identification), M/S (Music/speech), AF

Basic electronics skills are required for proper
installation of this device! No cables, boxes or adapters are supplied with this device.
On request the device can be supplied with the header connector soldered (header
type and top/bottom side must be specified). If you prefer complete plug-and-go solution
rather, look at the PIRA32.
and first opening select appropriate connection parameters on Hardware card. The software
can send actual song artist and title information if your broadcast automation system
provides on-air text file.
In this configuration the RDS encoder can be
controlled by the TinyRDS Windows application. The basic connection is extremely simple
since the MicroRDS incorporates all hardware necessary. You only require a 5V power supply
and standard DSUB connector. The RDS signal output that can be fed directly to RDS, MPX or
SCA modulation input of your FM exciter.
