[EAS] My article

[Tom Taggart]

As I understand Jim Gorman's box, it takes the CAP text data
and converts it to computer generated audio (think "Perfect
Paul") and sends it --as audio- to the EAS decoder box, with
FSK header and EOM attached.

To the EAS decoder, the CAP add-on audio becomes nothing
more than another source.  So the decoder will then trigger
the alert, either just turning on the speaker or also doing
a program interrupt, depending on the EAS box's internal
programming. 

Hence the logging of incoming CAP alerts is then done by the
existing EAS equipment.

This has certain installation advantages both at my two
stations with the combined site, and at my 3rd station. For
example, at the combined site I have the EAS decoder in the
control room, but my tuners for the FM relays and NWS are in
another room, away from the computer equipment, and closer
to the grounding for those outside antennas.  My the cable
modem is here as well (also for grounding reasons!)  As well
as my network switch.  So it's easier to connect another box
to the internet here, rather than in the control room.  Then
I just fish another audio pair over to the EAS decoder. 

Gorman Redlich is only 45 minutes from me--I saw Jim's early
prototype CAP add-on (and convinced him to cut holes in the
front panel so it got some air circulation).  His decoders
can be easily upgraded to handle new activation codes (for
example, the Governor's priority message) as well as to
change the activation priority as specified by the station.
