Fredericksburg to Join Stafford System

Uniden Announces ProVoice Upgrade for x36 Scanners

Today, Uniden announced an upgrade for the BCD436HP and BCD536HP scanners to allow monitoring of ProVoice communications. The upgrade will be available next month and cost $50. ProVoice communications have previously only been monitorable with programs such as DSD and DSD+.

EDACS (and ProVoice) have essentially reached end-of-life status - most of these systems are being upgraded to other formats in the United States. Still, there are a few major cities using these systems, so it will be a welcome upgrade for some.
