Abstract

Two-way radio communications systems are normally controlled from a dispatch position via a control console. Since the dispatcher is the most important controlling element of the system it is important that the over-the-air audio be of the high- est quality. Further, since dispatching is done on a 24-hour around the clock basis, various personnel with varying voice characteristics are transmitted by the same console position.

INTRODUCTION

  Two-way radio communications systems are normally controlled from a dispatch position via a control console. Since the dispatcher is the most important controlling element of the system it is important that the over-the-air audio be of the high- est quality. Further, since dispatching is done on a 24-hour around the clock basis, various personnel with varying voice characteristics are transmitted by the same console position.

STATEMENT OF PROBLEM

   Console operators frequently use different microphones and/or headsets at a given console operating position. When a console position is ini- tially set up, console mic-audio level settings are set and optimized for one type of microphone and one particular voice . . . . . . . that of the installer. After
installation, no easy adjustments are available to compensate for variations between operators' voice characteristics and/or microphone (headset) types. PROPOSED SOLUTION

  The console operator would scroll down a menu of operators listed on a display. Once that opera- tor's name is reached he or she depresses a 'set' but- ton. This would activate the electronics in the con- sole that would set levels and audio tailor parame-

ters for that particular operator and the mic (headset) being used. Test sentences would be spoken during the set up. Depressing the 'set' button would now enter all par...
