🛰️ W9EAU 146.91 MHz Repeater — Primary VHF System

The Eau Claire Amateur Radio Club (ECARC) operates the W9EAU repeater on 146.910 MHz in the 2-meter band.

Key details:

  • 📡 Frequency: 146.910 MHz (output) with a -0.600 MHz offset and a 110.9 Hz CTCSS tone for access.
  • 📍 Location: Eau Claire, Wisconsin — serving the Chippewa Valley and surrounding areas.
  • 📻 Modes: Analog FM (including Yaesu System Fusion digital/analog on many ECARC repeaters).

Purpose and Use:

  • The 146.91 MHz repeater serves as the primary VHF repeater for the club and is widely used by local hams for everyday communication.
  • It also plays an important role in Emcomm (Emergency Communications) — especially for the Eau Claire County Amateur Radio Emergency Service (ARES), providing a robust communications channel during drills, severe weather activations, and public service events.
  • When severe weather is in the area, local Skywarn nets may be activated on this frequency so trained volunteer spotters and radio operators can share real-time observations with National Weather Service offices and emergency agencies.
