Welcome to the Tri-County Amateur Radio Club – W9MQB

We operate in south central Wisconsin to provide supplementary communications in times of emergency and to lend support to all Hams as they enjoy and develop the hobby.
Hams from Jefferson, Rock and Walworth Counties volunteer their talents and equipment to serve other agencies and the public to provide reliable communications for local emergencies, assist the National Weather Service during times of severe weather, as well as the Tour de Fort Bicycle Ride, Jefferson County Literacy Council Bike Ride, and Great Midwest Relay Race.

TCARC maintains a VHF repeater on 145.49 MHz, negative offset, with a CTCSS tone of 123.0.
