[EAS] The Daisy Chain

[Gary Timm]

Harold,
You mentioned that the ENDEC does not record audio for alerts that are Log Only.  Since all of us have RWT set as Log Only, even if a PEP source sends audio in an RWT, the ENDEC will not record it and we will not be able to check it - if I understand correctly.

I noticed that FEMA sent an RWT from their EAS unit at my state's PEP station during the middle of the night in the weeks before this years NPT, and I understand that RWT had audio in it, but the audio wasn't in the ENDEC log as the event was Log Only.

Would there be a possibility of adding an "Always record audio" to the log menu or to the Incoming Filter?  I realize this could also be accomplished by setting up the RWT for a 1-minute Timed Ignore, but during that 1 minute it would appear as an Incoming Alert and could be forwarded by someone, no?

Sometimes it would be useful to be able to hear the audio of a Log Only event that wasn't anticipated in the programming of that event, or maybe its just a one-time event you'd like to hear.  That Log Only audio would be nice.

Dave,

This time, not as close as you usually are.

The Sage ENDEC has always worked as I describe below, back to the 1996 release of the 1822.

Once two of the three headers in an alert have matched each other, and the ENDEC has decided that this alert is eligible to air (not log -only or no matching filter), then it turns on its recorder and also starts looking for the two-tone signal or the 1050 hz signal.  If it is detected, then the recorder is "rewound" and restarts once the signal goes away (with a small debounce capability for a short dropout).  There is a  maximum  time the ENDEC looks for the signal until it assumes there isn't one (it is longer for an NWS input), and a maximum length of tone it is willing to believe.  After the above, alert sequence proceeds.
