I admit I wasn't thinking that far into it -- I was hung up on the
notion of generating SAME codes for the purpose of testing decoders.
That would be a slick little gadget. Since the SAME codes include EOM
that would allow the repeater to go back to normal operations when the
message ended. I see a need to control warnings coming from the
decoder independently, though; after the horn has blown for a tornado
warning one's users probably wouldn't be any too interested in a severe
T'storm watch. Possibly something like the decoder outputs as one input
to an AND gate with the other being a latch, then all 31 AND gates
feeding into a single OR gate.
