[aprssig] NWS Warning Filter

[David Andrzejewski]

I'm interested in receiving all NWS warnings sent to APRS-IS by AE5PL, 
not just the ones in my local area (for logging purposes).

If my filter is something like this:

filter r/41/-81/100 t/n

I should receive all of them, correct?  That range filter won't limit it 
to my local area?  My understanding is that filters should be additive.

Thanks!
