Central Idaho Amateur
Radio Club

The Central Idaho Amateur Radio Club has a primary service area that includes Adams County, Valley County and Southern Idaho County. Central Idaho Amateur Radio Club communications services may extend into other areas where coverage is available or where radio linking or bridging to the Brandmeister DMR network may be available. The Central Idaho Amateur Radio Club welcomes Amateur Radio operators from both inside and outside the Central Idaho Amateur Radio Club primary service area.

The Central Idaho Amateur Radio Club (CIARC) was founded in the early 1980's. Lenard Crogh, W7HXU, was one of the first amateur radio operators to install a 2m repeater on No Business Mountain - Lookout Peak in the late 1980's. The No Business Mountain repeater operated on 147.020 MHz with a positive (+) offset and a 100.0 Hz CTCSS tone.

In January of 2009, the Central Idaho Amateur Radio Club, with the permission of Brundage Mountain Ski Patrol and Brundage Associates installed a 70cm repeater on Brundage Mountain. The Brundage Mountain repeater operated on 442.500 MHz with a positive (+) offset and a 100.0 Hz CTCSS tone.

In the summer of 2012, additional linking capabilities were added to the Central Idaho Amateur Radio Club repeaters, with a focus toward emergency communications capabilities and to provide an extensible repeater network. This includes a 33cm link back-bone. Additional services, first made available in 2017, include access to the Brandmeister DMR network when member affiliated repeaters are linked into the network.

Random Operating Tip



The goal of any communication should be to accurately communicate a message with brevity and clarity while adhering to NET protocols. Successful attainment of these goals results in minimum bandwidth consumption, which leads to the ability of the NET to handle a higher number of traffic messages, the lossless communication of information, resulting in accurate conveying of information, and minimized latency for those stations needing to pass traffic after you.

Non-critical transmissions of a casual nature have no place in emergency NET operations. Although tolerated during scheduled directed NETs, such transmissions should be held until formal NET traffic has been completed.

PLEASE pass operating tips on to others!

  Meeting Map  


There are several opportunities each week to participate in NETs. This includes Central Idaho Amateur Radio Club related NETs and NETs that are affiliated with the club or its members, such as Amateur Radio Emergency Services (ARES).

The CIARC NET is held monthly, on the Wednesday immediately preceding the meeting, at 8:00 PM local time. The CIARC NET operates on the No Business Mt. and Brundage Mt. repeaters. Check the repeater status page if you are not able to access one of the CIARC repeaters. CIARC members may obtain a copy of the NET script by logging in and selecting the Net Boiler Plate (Roll Call) menu item that can be found under the Members menu.

The Idaho ARES District 3 NET is held weekly on each Monday night at 2030 hours local (Mountain) time. This NET is conducted on the K7BSE repeater (i.e. 146.940 MHz, -offset, 100.0 Hz CTCSS) and is available via a link to the K7ZZL 70cm repeater on Snowbank Mt. (i.e. 443.300 MHz, +offset, 110.0 Hz CTCSS), and then by a remote base connection to the CIARC Brundage Mt. repeater. When all components are operating, amateur radio operators may participate through any of these repeaters. Additional information can be obtained by clicking here. NOTE: The K7ZZL 70cm repeater component of this network is currently out of service, and the loss of this critical component also results in the loss of the ability to participate in this NET while using the CIARC repeaters at No Business Mt. or Brundage Mt., or the KA7ERV repeater that is located on Pilot Peak in Boise Co. Direct access to the K7BSE 2m repeater is possible from many parts of Long Valley in Valley County when mobile power levels and a gain antenna are used.

Valley County ARES periodically conducts net operations on either the CIARC repeater network, or on the Valley County ARES Simplex frequency of 147.530 MHz. These NETS are conducted to provide both training and an opportunity to improve operator proficiency in traffic handling and other Valley County ARES activities. The Valley County ARES NETS are not on a fixed schedule. Announcements of Valley County ARES activities occurs via email distribution to registered Idaho ARES members within Valley County. The best way to stay informed of these activities is to join Idaho ARES (it is FREE) by visiting the Idaho ARES web-site. You can register to join Idaho ARES by clicking here.

What is the ARRL Field Day?

Each year, on the last weekend of June, the American Radio Relay League (ARRL), the world’s largest and oldest amateur radio organization, hosts its annual Field Day. It is an exercise encouraging emergency communications readiness among amateur radio operators. In the United States, Field Day is the largest single annual emergency preparedness exercise, with over 40,000 operators participating. The use of alternative power sources is encouraged to prepare for those instances when utilities fail. Operations typically last over a twenty-four hour period, testing our capability to respond to an actual emergency.

Please visit our Field Day Page (available under the Public Service menu) for additional information.
