Within each group are 4 blocks sized 26bits wide. Thanks to all of you who have contributed so far and thank you for visiting! However the 53 kHz cutoff is entirely dependent on the performance of the 15 kHz low pass filters used before the stereo encoder. First block of every group, will always be the program identification code. Each group type may have a secondary version availableThe data-link layer describes the baseband coding of which the largest element in the structure is called a "group" sized 104 bits wide. Find top stations in Hartford, CT (33) United States. While the country code is specified by the standard, bit 11 to bit 0 is specified by each country local authorities.Block 3 is used for repeating program identification code.As we have already described previous fields above, these dot points below show just the application specific fields.A RDS message group consist of two versions of the group structure, designated in the standard as type A, and type B.Within Block 1 and Block 2 are structures that will always be present in both group versions, for fast and responsive identifications. The following information fields are normally contained in the RDS data: Sinclair-owned '93.7 The Coast' WKOC and '96X' WROX are the two new stations that are now utilizing this feature.
Each block contains a 16bit data word and a 10 bit checkword.
All group is sent most significant byte first, with no gap between groups or blocks.This allows for quick identification of radio program type, based on country, coverage area, and program reference number. DPS: BBC World News... PTY: Public RT 1: NEWS & INFO for GRANITE STATE PI: 6168 AF: 88.3, 91.3, 97.3, 103.9, 104.3 6/14/09: I just want to start off by thanking you for continued loyalty to RDSList.com. The following is a list of FCC-licensed radio stations in the U.S. state of Connecticut, which can be sorted by their call signs, frequencies, cities of license, licensees, and programming formats. Services: PS, RT, PI, CT PS: HOT NEW COUNTRY AND YOUR ALL TIME FAVORITES CRESTON RADIO RT 1 : HOT NEW COUNTRY AND YOUR ALL TIME FAVORITES CRESTON RADIO The usage by radio stations of the RDS feature that newer car radios have has just doubled from a whopping two stations to four stations. In older equipment, these filters were only designed to protect the 19 kHz pilot and sometimes did not provide sufficient protection to the RDS subcarrier when a significant amount of stereo information was present. I … More modern composite clippers include filtering to protect the RDS subcarrier.The station name and decoder identification code is sent progressively over 4 groups, where the offset is defined by bit C1 and C0.The following information fields are normally contained in the RDS data:The RDS-Forum (Geneva/CH) decided at its annual meeting (8-9 June 2015) in Glion/Montreux to bring the new standard RDS2 on the way. rt 2: our station is proud to bring this latest technology to you... 97.3 WMEE - Fort Wayne, IN Last Updated: 9/28/05 DPS: THE BLAZER 91.1 WVUB YOUR 1 HIT MUSIC STATION + Artist/Title PTY: Information & Jazz on Sundays; Adult Hits Monday - Friday RT 1: THE BLAZER 91.1 WVUB CT: Clock is 1 hour slow If we don't have your station listed, please submit it!! An RDS database of almost 800 stations from Qu�bec City to Topeka; by Chris Kadlec, WTFDA Northeast & Midwest RDS Database - by Chris Kadlec Select your region on the interactive map or locate it in the alphabetical list below Including Chicago, Joliet, Kankakee, Aurora, Waukegan, McHenry, Gary, and the Calumet Region This is a short list of the full group type. Hartford, CT All Genres. The standard will be created in close collaboration with U.S. colleagues from NRSC RBDS-Subcommittee and should offer a unified platform for FM broadcasting and data services worldwide.As far as implementation is concerned, most car stereos will support at least AF, EON, REG, PS and TA/TP.The following table lists the RDS and RBDS program type (PTY) codes and their meanings:The identification of a RDS message blocks and groups is done via a 10-bit offset table containing offset word: A, B, C, C' , and D (in RBDS this also includes "E").These are non comprehensive examples that covers just the simple messages likes station name, radio text, and date time.The clock time group is inserted so that the minute edge will occur within +/- 0.1 seconds of the end of the clock time group.When group type 4A is used, it shall be transmitted every minute according to EN 50067.Time and date are packed as these:The RDS subcarrier typically uses 2–4 kHz of carrier deviation.
Therefore, the deviation available for the program material is reduced by this amount, assuming the usual 75 kHz deviation limit is not exceeded. In this situation, stereo enhancement devices combined with aggressive audio processing could render the RDS subcarrier unreceivable.Composite clipping systems may also degrade the RDS sub-carrier because of the harmonics created by the clipping. In the case of the FM Tuner RDA5807M IC, it displays a group in separate 16bits blocks over four i2c registers. The second block dedicates the first 4 bits for Application/Group Type.There are a growing number of RDS implementations in portable audio and navigation devices thanks to lower-priced, small-footprint solutions.The RDS sub-carrier at 57 kHz occupies ±2 kHz of the composite spectrum which in theory keeps it above the upper cutoff of the stereo subcarrier at 53 kHz. Because of YOU we currently have 1,551 RDS stations listed!
