Logging recorder system for trunking radio
First Claim
1. A logging recorder for a trunking radio system having a plurality of channels, wherein one of said channels carries channel assignment information and each of the others of said channels for carrying streams of segments from unrelated conversations, comprising:
- a plurality of fixed frequency radios each of which monitors a selected one of said plurality of channels;
a controller which monitors said fixed frequency radios and generates identification information corresponding to said segments for each particular conversation based upon said channel assignment information; and
means for storing said segments and said identification information on a mass storage device.

Abstract
A logging recorder system for trunking radio includes a device which monitors a plurality of channels of the trunking radio system and outputs analog signals representative thereof. A digitizer is then provided for digitizing the analog signals, and a controller breaks the digitized signals into segments and stores the segments on a mass storage device. The controller also generates an index of locations of the segments on the mass storage device. The controller may then be used to selectively play back a desired conversation by automatically combining segments from the mass storage device based on the index.
