[EAS] General Question: Can't it be a software solution?

[Lowell Kiesow]

The filtering issue that many older EAS boxes will log every message 
they hear (I think TFT does this).  Others will log everything it 
hears matching its location code filter (Burk?).  A box with more 
flexible filtering can be set to completely ignore tests and messages 
that you don't want.  As I mentioned before, depending on what 
happens in your state, and with FEMA, NWS, etc., you may get many 
times more messages than you do now, and if they all print on paper 
tape, it could turn into a headache.
