Check the listing for details. RDS Encoder Circuit Board Module for PLL FM Transmitter Radio Broadcast Station. Color: Green, Condition: New. Listed at 59.00 USD. Part Number: RBS-RF104RDS Encoder Circuit Board Module for PLL FM Transmitter Radio Broadcast Station with Stereo Encoder MPX ConnectionRDS Encoder is an efficient protocol based solution for radio broadcast stations to be able to communicate and share information with listeners. This RDS Encoder circuit module is budget and user friendly, supports all commonly used RDS protocol. This circuit module provides a reliable, compact structure and functionality with its signal processing algorithm, and offers a low-cost solution from amateur users to large-scale RDS radio broadcasting stations.This RDS Encoder circuit module supports both static and dynamic data transmission. Data transfer takes place over the USB protocol. There are MPX input and RDS Encoder output on the module. MPX audio signal and RDS signal are seamlessly combined on this module. Another option is to use only the RDS output. MPX output level and RDS level can be adjusted with the trimpots on the module.The software for RDS is very useful and simple. All common RDS data formats are supported by software and circuit module collaboration. The software is completely free.

Package Included- RDS Circuit Module,- Software and driver CD. Application Instructions* Red Led (named RDS) indicates RDS broadcast activity. The blue led (named Data) indicates the activation of the data sent by the software.* Increase the MPX level as much as possible without saturation. Make sure your signal source has a high gain, high output gain gives a higher signal noise ratio.* Turn on the RDS Signal level with a maximum of 25% trimpot according to the MPX level. Our recommendation is to set a gain of around 10% at most. Higher RDS gain causes the S/N value to decrease.* The Audio signal you connect to the MPX input is combined with the RDS signal on the circuit module and this signal is output. You can connect this output directly to the transmitter.* Another connection option is to use the RDS output directly. For example, the RDS output can be connected to the Stereo Encoder input (If your Stereo Encoder supports it.)* 57kHz Sync output is optional for use. With this signal, it can be synchronized with other devices.* This RDS circuit module is compatible with our HQ Stereo encoder module, FM clipper limiter compressor module and PLL FM transmitter module. Note: The block representation in the photos is the connection diagram of our FM Limiter, HQ Stereo Encoder and RDS Encoder circuit modules to our PLL FM transmitter. This is only the recommended connection type. Each of our modules and transmitter can work independently, can be used with amateur or professional devices and circuit modules.
