Washtenaw County siren test net today. About two dozen radio amateurs each assigned a siren, at noon the test runs, we report back correct or incorrect operations.
In most tests early in the season there are one or two sirens misbehaving or in need of tree trimming.
The test net is coordinated by Washtenaw ARPSC and the county EOC. City of Ann Arbor sirens are tested on a different schedule and without a similar volunteer monitoring system.
Sirens! #sofun
