The interesting bit here would be establishing how the data is conveyed. The Cadet card gives you raw blocks (A-D, or A-E in the case of some messaging services) on reads of /dev/radio and then userspace has to parse it. It appears that this other card actually provides sane interpretations of the data for you, so it won't work the same way. Ultimately it's all the same content, but the way you get to it has very little in common. If there's sufficient interest I'll help out with the Cadet side since there are a few stations here providing data for testing.
