The Sunset Amateur Radio Club (SEARC) is one of Oregon's oldest amateur radio clubs. It was formed in 1931. SEARC continues to be active in Clatsop County and the lower Columbia River area providing emergency and public service communications for a wide variety of events.

The SEARC operates and maintains several communication repeaters in the Clatsop and Pacific areas and are open to use by all amateurs. They are available for emergency radio communications in the event of an emergency such as a tsunami or an earthquake.

Support for maintenance and operation of these repeaters comes from membership dues and participating in a wide variety of fund raising events and donations.
