"ASTRO Digital Technology"
Los Angeles: In 1992, the voting Los Angeles public approved a $235
million dollar bond measure. The purpose of the bond measure was to build
two new dispatch centers, one in the metropolitan Los Angeles area and the
second in the San Fernando Valley, and to replace the Master Radio System.
The Master Radio System is a 56 channel Ultra High Frequency (UHF) simulcast
system that utilizes Motorola ASTRO digital technology. In 1996, the
Department began deployment of the new ASTROs [radios] however, up until
recently, these radios were being operated in an analog mode. Over the last
several weeks, the Department has completely switched operation from an
analog to digital mode.
Over the course of the switch, the Department and Motorola have received
operational feedback from our patrol officers. Officers have voiced concerns
over operational aspects of the radio. Some of the most frequently cited
concerns by officers include, the frequent fluctuations in volume levels
during radio communications, periodic echoing effects during voice
transmissions, degradations during unit-to-unit voice communications in the
simplex mode and problems during air-to-ground transmissions.
The Department is acutely aware of these concerns and is working in a
concerted, cooperative effort with representatives of Motorola to address
these issues. Efforts are currently under way to resolve the issues that
have been raised. We recognize that some of the issues need to be addressed
from a training standpoint.
The Department is very much committed to providing our officers with the
best possible equipment and to affording them the type of environment that
will allow them to effectively and safely perform their duties. To this end,
we are aggressively working with Motorola to make this system the best
possible for our officers.
