It’s not important if you use this RDS encoder with one transistor FM bug or 1 kW transmitter. It will give your station all common RDS features: 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 mounting into a small transmitter.
The design is based on the MRDS192 chip which processes and stores the data and generates output signal. Analogue part is very simple due to fully digital generated RDS signal. * https://pira.cz/rds/show.asp?art=minirds_encoder
Adafruit Si4713 FM Radio Transmitter with RDS/RDBS Support
This eBook was updated in December 2021. It was compiled from contributions of a team of RDS Forum members who have been closely involved in the RDS development for over two decades. Readers will learn about the possibilities, seen from within the RDS Forum, of the very best possible way to use this well proven, and frequently updated FM radio technology. In doing so it takes into account the new possibilities offered by RDS2 and explains how to use these new options for designing open data applications. This book gives a general description of the RDS system and all RDS features, it explains the UECP and how to monitor and generate RDS signals on air, the use of RDS in the automotive world, the principles of RDS-TMC and the possibilities for using the extension of RDS2. This book is a « must read » for everyone interested in the subject.
Un émetteur de radiodiffusion FM à peu près moderne reste assez petit. Une baie 19" est souvent suffisante. Mais toute la quincaillerie qui gravite autour, RDS, limiteur, compresseur et autres, prend bien plus de place.
Avec les semiconducteurs ces fonctions « petit signal » (RDS, limiteur, compresseur et autres) peuvent tenir dans moins grand qu’une boite de chaussures !
Bonjour,
Combien, parmi « les masses », lisent couramment l’anglais, fût-il technique ?
Quant à ceux qui le lisent, ils ne chercheront vraisemblablement pas l’info sur ce forum.
CQFD
