Information for Scanner Listeners
Local law enforcement agencies completed the transition to a new P25 trunked radio system on Thursday, July 27th. The District is working on establishing a "bridge" from to the new system to the old to provide interoperability with the State Police until late August when OSP transitions to the new system. The bridge should be on-line in the next few days.
Note that in late August, the old analog law enforcement radio system will be decommissioned. Please download to the information sheet at the bottom of the page for more information.

Here is what the info sheet says. Nothing really new:
Deschutes County 9-1-1 Service District
Radio System Fact Sheet
 The Deschutes County 9-1-1 Service District is in the process of replacing its aging
analog-based radio system with a new digital trunked system that fixes gaps in
coverage and helps keep local first responders safe.
 The shift to the new system will impact residents who have previously monitored
scanner traffic with smartphone apps or analog scanners.
 On the new radio system, law enforcement dispatch channels will be encrypted
and will not be able to be monitored over the air. Law enforcement dispatch traffic
will continue to be recorded by 9-1-1 and will be available via a public records
request.
 Starting in late August, unencrypted law enforcement dispatch radio traffic will be
published online, but with a 30-minute delay.
 This transition means people with scanners will not be able to receive law
enforcement radio traffic. Listeners interested in monitoring those channels will
need to use the internet-based stream when it becomes available in late-August.
 There will not be a delay for the radio channels used by local fire service agencies,
nor will those channels be encrypted.
