Testing is continuing on Klickitat County’s new emergency communications system. County Commissioner Jim Sizemore says while construction on the system is done, there is some fine-tuning that still needs to be done. Some of it involves the mountain top tower sites that give the county the best coverage, but also are susceptible to interference. Sizemore says the interference has not caused any issues for emergency response. He noted some of the testing found some improper wiring connections.
