BEND, Ore. (AP) — All seven Deschutes County law enforcement unions have filed a joint complaint with local leaders, and one has filed a state complaint that a new digital radio system installed in July works so poorly it puts their lives and those of the public at risk.

KTVZ-TV reported Wednesday that a Dec. 7 letter from the unions to law enforcement leaders calls for immediate action "to fix serious problems" with the radio system.

The problems listed include volume levels that are too low, dropped radio signals and garbled radio transmissions.

Deschutes County 911 Director Steve Reinke confirmed the problems and said the system wasn't properly configured by the provider, Harris.

Harris spokeswoman Natalie Ciao said in a statement that a Harris team has been in Bend since early January and will continue working with the city and county to address challenges and optimize the system's performance.
