Page 11: Overview
Digital Modulation Technology The MTH500 is a portable radio that has two models operating in two different frequency ranges: R1: 380-400 MHz and R2: 410-430 MHz. These radios can operate in dispatch and phone mode. Also, these radios can operate in TMO (Trunked Mode Operation) and DMO (Direct Mode Operation) modes. -
Page 12: Voice Compression Technology
Voice compression reduces the number of bits per second while maintaining the voice at an acceptable quality level. The MTH500 uses a coding technique called ACELP (Algebraic Code Excited Linear Prediction). The compressed voice-data bits modulate the RF signal. -
