I found two files from Sweden (recorded through Airspy Server last year) with "Warning receiver" thanks to egrep -rni -e "ODA" *.txt

E424_-_2019-04-29_20-25-12.txt
E424_-_2019-04-29_20-23-20.zip

ODA 1:   AID        = 6A7A

Assuming that the ODA code is the last block in each line of rdsspy recordings, I used
egrep -rni -e "CB73|4C59|CC21|1DC2|4AA1|0093|1BDA|0F87|0E2C|1D47|4BA2|E5D7|0C24|CD9E|4AB7|1CB1|4D9A|E319|0E31|CB97|E440|4D95|1E8F|0D8B|E4A6|1C5E|0BCB|CE6B|1DC5|4D87|0D45|CD47|0CC1|1C68|7373|5757|6552|125F|50DD|6363|6365|6A7A|A911|4400|A112|C563|C3A1|E911|E1C1|E411|E123|C350|C4D4|C3C3|C3B0|C737|C3A1|C549|C6A7"
to checked all the spyfiles in https://github.com/walczakp/rds-spy-logs for ODA other than RT+ and TMC.

windytan · 2020-08-21T05:28:23Z

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 I think I'll have Redsea print out the raw ODA data in case the application is not supported, since some of these are unpublished.

windytan · 2020-08-21T08:07:05Z

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.

windytan · 2020-08-21T13:55:34Z

I was wrong, there are more ODAs! These ones have 3A groups:

10107     "app_name": "RDS-TMC: ALERT-C",
  853     "app_name": "RadioText+ (RT+)",
  399     "app_name": "Enhanced early warning system",
   55     "app_name": "iTunes Tagging",
   20     "app_name": "Cross referencing DAB within RDS",
   12     "app_name": "Warning receiver",

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.

andimik · 2020-08-21T14:11:16Z

Sure, you can mention my name Andreas Mikula

andimik · 2020-08-21T16:06:51Z

Not, not all of them are errors ;)

Let's see what we still have remaining:

(for f in rds-spy-logs/* rds-spy-logs/**/*; do redsea --input hex < $f; done) | grep "Unimplemented ODA"|sed 's/.*$"pi":"0x...."$.*$ODA app ....$".*/\1 \2/'|sort|uniq -c|sort -rn|grep -v "^ \+1 "

It produces interesting list, which are all from logs dated 2019–2020:

PI	Station name	ODA ID	Unknown ODA name	ODA group	# 3A groups
7DC9	🇺🇸 Z88.3 FM (WPOZ)	7373	Enhanced early warning system	12A	399
4569	🇺🇸 KFOX (KUFX)	C3B0	iTunes tagging	11A	22
5CBC	🇺🇸 WDBO 96.5	C3B0	iTunes tagging	11A	21
EC24	🇸🇪 SR P4 Stockholm	6A7A	Warning receiver	12A	13
8FC4	🇺🇸 WWKA	C3B0	iTunes tagging	11A	12
E224	🇸🇪 SR P4	6A7A	Warning receiver	12A	10
F216	🇫🇷 RMC	2020	–	14B	3
EC02	🇸🇪 SR P2	1BC9	–	8A	2
E424	🇸🇪 SR P4 Kristianstad	6A7A	Warning receiver	12A	2
E132	🇷🇴 Real FM 90.2	414C	–	12A	2
E05F	🇷🇴 Virgin 100.2 FM	3130	–	15B	2

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.
