Due to an error on my part, we have two things called "Catena 4420". We can simply rename the "Radio FeatherWing" Catena 4420 to some other number -- I think Catena 4415 would be OK. (The 441x series is pretty much obsolete now that we have the 4450, anyway.) That would require changes here, changes in https://github.com/mcci-catena/Catena4410-Sketches, and changes in https://github.com/mcci-catena/Catena4410-Arduino-Library.
