The Emergency Alert System (EAS) is the system whereby Federal, 
State, and Local authorities can send safety alerts to various 
geographic areas by way of public media. 
The EAS is a web-like system of communication interlinks utilizing 
both analog radio, and digital information via the internet. EAS 
signals come directly from KCBS (AM) and KQED (FM). The third 
source is from a computer in the engineering room that listens 
constantly for messages coming over the internet (CAPCON). 
For all alerts, our broadcast is interrupted and the official message 
is passed on from the originator of the message, through KALX to 
our listeners. Tests that are received are not re-broadcast by KALX, 
except for the Required Monthly Test (RMT), which happens only 
SECTION THREE - EAS

KALX Operators Manual

...the Required Monthly Test (RMT) which occurs 
on the second Tuesday of the month. 
SECTION THREE - EAS 
on the second Tuesday of the 
month. 
The EAS signal begins with 
the buzzy burst of information 
repeated three times. If the signal 
is a test, there is the familiar 
two-tone attention signal, a short 
test message, and then the end 
tones. An alert follows the same 
program, but the voice message 
is specific to whatever the alert 
is about, a Child Abduction 
Emergency (CAE), a Shelter in 
Place, etc. 
When the signal is detected, the 
EAS receiver turns on, decodes 
the information, prints the log 
tape, and, if warranted, interrupts 
our broadcast with the alert or 
RMT message. 
.. TESTS .. 
We broadcast weekly tests on a 
random schedule. Once a month, 
these tests are coordinated with 
all the other participating radio, 
television and cable stations in 
the Bay Area; this is the RMT. All 
stations will re-broadcast this test 
within 15 minutes of receiving 
the test from KCBS, KQED, or 
CAPCON. These RMT tests 
received on a monthly basis are 
automatically forwarded by 
KALX. This is why your show 
may be interrupted in the middle 
of a cut.

SECTION THREE - EAS 
.. ALERTS .. 
The receiver in Air is 
programmed to receive alerts 
and digitally process the 
information that is received. The 
receiver filters the messages and 
automatically forwards the 
ones that apply to our local 
counties. Again, an alert will 
immediately interrupt the show 
that is on the air.
