First time poster who is immensely satisfied with Stereo-Tool, blows Airomate out of the water for sure. One feature missing though seems to be RT+, I use my Zune HD to test RDBS output and would love to allow listeners to be able to tag their songs on their Zune, iPods, car stereos etc. Is there a way I can implement it myself or is this a feature being worked on?

Thanks for your time and love the software!

I have read about that in the past and I do want to implement it at some point. Only at this moment there are other things that have a much higher priority, so don't expect it any time soon.

Simply replying in this post because making a new topic on it would be pointless.

With the new version of Stereo Tool on the way, perhaps RT+ can be made part of it? There is plenty of documentation available and it would be hugely welcome. I have all the equipment needed to test it if that is an issue.

I did attempt to set it up in GNURadio, however the source code was over 3 years old and incomparable.

I am more than willing to test this for you. Anyway, just in case, here is some documentation as well:

http://www.rds.org.uk/2010/RTPlus-Promotion.htm

The below picture shows what it looks like. (Not my station, and it is on an HD station but the Title/Artist info looks the same for both HD and regular RDBS on my Zune HD)

Also the output on an iPod Nano, showing the full Radiotext as well as tagging output/

Several smart-phones are starting to implement FM radios with RDS/ODA capabilities, as are most cars.

Hm, there are a few extra bits that are not present in normal RDS blocks. CB and SCB are new. Also, the toggle bit needs info because it needs to know when a new track starts.

Most importantly, I think RT+ doesn't support multiple RT texts - so the RT text must always be the same, only the track name should be filled in. So "You're listening to Weird Titan Radio/Now playing Paul Elstak - Ik Haat Je" wouldn't work because the text at the indicated position would appear and disappear all the time.

So it will be a bit tricky. I could check when the text changes and flip the toggle bit when that happens.

In the input field, things could be defined as - for example - \+A{Artist name} \+T{Title}, or potentially (since there are so many classes) with numbers: \+31{Artist name} (No idea if that number is correct, I just typed something).

Which leaves CB and SCB. I'll have to read the official specification to see if I'm missing anything, and WHEN these values need to be transmitted.

Good to hear, again I am more than willing to be a tester for this code if you need it. My low power setup works very well with radiotext as it is.
