Having just replied to the TOM33P post above, if you find out any info let me know. I have never seen advance lists of these codes although I do not spend very long looking for them.
The RYR, TOM and TCX codes change everytime the clocks change so my list is not very accurate yet as I am still building it back up after the recent clocks going backwards.
I cannot help with the DLH codes as I do not keep a list. These rarely fly over me so I do not have as much interest as the others.
Anyway, hope someone can help you and possibly me as well.
