Spectra Engineering is pleased to announce the release of the Digital APCO P25 Repeater \ Base Station variant of the MX800 at the 2008 International Wireless Communications Expo (IWCE) in Las Vegas.

APCO Project 25 (P25) is the industry wide effort to set the standards of uniform digital Two-Way Radio for public safety organizations and has also been selected in other private system application(s), worldwide.

A major advantage for using P25 is to reduce spectrum bandwidth usage and the ability to recover excellent audio quality from noisier signals, where compared to analogue signals, the noise is always accumulative and degrades the audio quality.

Main features of the MX800 P25 Base Station & Repeater:

  • P25 Compliant 7200 bps IMBE™ Enhanced Vocoder.
  • P25 Digital audio to speaker & line.
  • P25 Digital audio from Mic socket & line.
  • Repeats all P25 transmissions.
  • Repeats analog transmissions.
  • Automatically switches to P25 mode on reception of a P25 carrier.
    (Allowing analog radios to still work on the same system.)
  • P25 Digital can operate on any freq band.
  • P25 NAC programmable or transparent.
  • Passes P25 private call and group call.
  • Repeater passes P25 clear or encrypted.
  • Front panel indicators show P25 status.
  • Design based around proven MX800 architecture.
  • 255 channel capacity.
  • Flash based software design allows future upgrades for new features.
  • Standard Analog MX800 can be upgraded to P25.
  • Low power consumption.
  • RF Specs in Digital mode are the same as Analog mode.
  • Programmable External PTT mode, Digital or Analog.
  • (T82) Optional Ananlogue & Digital Fixed Station Interface.
  • (T83) Optional Data Packet Repeat mode.
