EDACS Provoice

From The RadioReference Wiki

ProVoice is Harris' implementation of IMBE digital modulation for radio communications. It is not APCO-25 compliant, but does use the same IMBE vocoder. AEGIS was a predecessor of ProVoice on EDACS Systems.

EDACS ProVoice systems use the MA/Com EDACS control channel.


Can This Mode Be Trunktracked?

  • Apart from using an actual ProVoice radio, these methods are also known to work;
    • Uniden's BCD436HP and BCD536HP allow users to monitor ProVoice traffic after purchase and installation of new firmware. See this page on the Uniden TWiki for information
    • ProVoice can also monitored using software (DSD, DSDPlus) in conjunction with a discriminator tapped scanner or SDR.

Known Users

San Antonio, Texas, and the State of Florida are using or are in the process of building ProVoice EDACS systems with ESK.

Cecil County, Maryland uses this mode for their county wide system
