Other ODA than RT+ and TMC #72

I found two files from Sweden (recorded through Airspy Server last year) with "Warning receiver" thanks to E424_-_2019-04-29_20-25-12.txt

Assuming that the ODA code is the last block in each line of rdsspy recordings, I used RDS2 ODA (hex 6365)

Thanks a lot! That looks like a very useful repo. I think I'll have Redsea print out the raw ODA data in case the application is not supported, since some of these are unpublished. |
Running all of these logs through redsea it seems that there are actual ODA groups for only iTunes tagging (USA PI codes 0x8FC4 and 0x4569) and DAB cross-referencing (UK PI codes 0xC204 and 0xC202). The rest are probably spurious errors or otherwise coincidental, but I'll leave the issue open in case there's more info about the iTunes protocol. |
I was wrong, there are more ODAs! These ones have 3A groups:
andimik, your contribution motivated quite a lot of new things that are now supported, is it OK to mention you in the changelog? You don't have to, of course. |
Sure, you can mention my name Andreas Mikula |
Not, not all of them are errors ;) On the Swedish programs like S4 for Stockholm
|
I found a list of most common ODAs also in the manual of a professional RDS encoder seller: Page 22 on https://pira.cz/fm_broadcast_analyzer/p75-p175-manual.pdf |
There is a Finnish program using RadioText Plus / RT+ for eRT (dec 9416, hex 0x4BD8)Enhanced RadioText / eRT (dec 25938, hex 0x6552)

Let's see what we still have remaining:
It produces interesting list, which are all from logs dated 2019–2020:
I believe 3130, 414C, 1BC9, 2020 are noise; they don't exist on my list. Then we're left with C3B0 ("iTunes tagging") on three US stations, 6A7A ("Warning receiver") on three Swedish stations, 7373 ("Enhanced early warning system") on one US station. I would like to stay away from public safety features, until we can get some kind of third-party safety audit (not planned). This leaves us with iTunes tagging. I'll close this ticket and open up a new one (#116) for anyone wishing to reverse engineer it. |

This is a PR from walczakp/rds-spy-logs#2
A list of all valid ODAs is at http://www.rds.org.uk/2010/pdf/R17_032_1.pdf
