[EAS] NOAA and attention tone

I just noticed something I hadn't noticed before... not sure if I just 
wasn't paying attention or if something has changed.  I noticed that the 
RMT sent by our local NOAA office didn't have the two-tone "attention 
tone".   It had their 1050 Hz tone which may be why I didn't pick up on 
the lack of attention tone before.  I don't have any other alerts from 
them recently enough to have audio recordings other than RWTs, which 
also lacked the attention tone.  So... a question... is that "normal" 
for alerts originated by NOAA Weather?

And a related question... our local office was one of the first in the 
country to forward non-weather alerts, using a SAGE ENDEC in series with 
their audio feed to their transmitter.  That SAGE, of course, IS 
generating the attention tone.  But... it is NOT generating the 1050 Hz 
tone that NOAA otherwise uses.  Anyone know if that poses any problems 
for them?  Would that prevent some weather radios from un-muting?  If it 
is an "all hazards" radio with SAME decoding... will it unmute if there 
isn't an attention tone? What about if there isn't an 1050 Hz tone?

Thanks

Dave
