Hi Group, I'm getting started in RDS and trying to develop a new application. My question is, do many U.S. broadcasters transmit clock time and date? Is this...
I'm looking for documentation (manuals, schematics, specifications, advertisements) for early RDS radios. I think Blaupunkt had the first commercial radio, and...
Did you ever find any of this information? I am tracing the history of RDS and ARI. I'm particularly interested in the the first delivered devices. My research...
Did you uncover historical information about RDS? I am looking for model numbers and all sorts of documentation on RDS from its first commercial days with...
What devices? RDS decoders? I think it was the TDA7330 from STM and SAA6579 from NXP. Maybe some high-class car-radios like Becker had a added "RDS pcb" with a...
Thank you for your answer. I was not quite clear in my request. I am looking for end-user consumer products such as automobile and portable receivers. Right...
That would be wonderful but so far has not proven productive, so any information will be quite helpful. If you know of any such online museums, please advise...
Sorry, I don't have the time for research. Otherwise if you can pay me? I have a list of almost all RDS decoder chips here (Out of one of my own projects): ...
Hi ! There is some nice TDA7330B based rds-decoder in files-section of group: de1103. File TDA7330.gif by "Jara". Another version of decoder (Puskas Barnabas)...
Thank you very much. I plan on getting your book as it looks like it will be a great help in understanding this technology. You mention ARI in the excerpted...
Thank you, Henry. You've put together quite a list of decoder chips. My need is simply for the technological development of the RDS and of ARI at this time,...
Yes. I'll be happy to share whatever I find out about this historical development. n Jim From: rdsforum@yahoogroups.com [mailto:rdsforum@yahoogroups.com] On ...
A local broadcaster I know asked if I could write a program to calculate the RDS PI field for use at his FM stations. He is a nice guy so I wrote it for him....
Looks pretty solid, no bugs to report here. Good work! Glad to see you're using Industry Canada's PI algorithm version 2 too. For the same application with a...
Hi, Could you pls let me know if RDS Logo is *required / mandatory* on devices that have RDS receiver chip? E.g., car radios, cellphones, etc. Or, the RDS logo...
Several months ago I stopped receiving RDS from a local radio station on all 3 of my radios while continuing to receive data from several other stations. The...
Or, maybe the 57KHz subcarrier is nor quite on 57KHz, maybe lower or higher. I've experimented changing the frequency of the rds subcarrier, alittle bit up and...
Do you have a correlation between specific rds decoder devices? Seems that most work as a DPSK decoder PLL in digital form. It will be interesting if a costas...
Most (if not all stereo FM stations) lock their 57kHz subcarrier to their 19kHz (or at least should be!). So, if their pilot drifts, their RDS could drift....
Hello -V, Look at <http://www.rds.org.uk/rds98/use_of_rds_logo.htm> This page applies to IEC 62106 Annex K. Annex K "RDS logo" is informative, not normative. ...
Perhaps a clarification to my orginal post is in order. My RDS knowledge is minimal at best, so anything I judge useful is being forwarded to the engineer at...
Brian, Found a bug in your PI program. Try these commands: pi 1FFF (returns KGBN) pi 2000 (retuns Invalid. Should be KGBO) pi 2200 (retusn invalid. Should be...
... Here's an update. The station engineer made some adjustments such that: a) My portable Roberts radio receives the scrolling data, b) My Sangean shows the...
You need to monitor your RDS subcarrier and it's data. Check out the Inovonics 510 <http://www.inovon.com/?a=2&s=4&i=16>. You should really know what you're...
Hi, I have a doubt on specs Annex E (both RBDS and EN 50067:1998): two control characters define the repertoire used for the message (both PS and RT groups),...
