[aprssig] Emergency Beacons

I wonder if those alarms work.  I don't believe I have ever received an
alarm.  I was supposed to receive an email but I didn't.  Does the D700
alarm if an emergency beacon is received?

Thanks for reminding us all of this error.  Let me remind everyone
else:::

Some "aprs" clone software does not even support STATUS.
And since a single APRS EMERGENCY packet triggers alarms
for EVERYONE, the best rule is never-ever send out a test 
emergency packet except on a NON-APRS frequency into a
dummy load where you are guaranteed that no one will 
receive it.

STATUS is dispayed separately from a POSIT and the
EMERGENCY bit is in the POSIT.... So again, NEVER
send out an emergency packet unless it is a REAL
emergency.

Thanks, for reminding us all of this operations scenario.
 Bob
