Our Mission

Arapahoe County Amateur Radio Emergency Service (ACARES) is a 501c3 non-profit public service organization, consisting of licensed Amateur Radio operators who have voluntarily registered their qualifications and equipment to provide communications needs in times of emergency and for public service events. ACARES is dedicated to serving Arapahoe County and the communities within by working hand in hand with local and state governments, agencies we have signed Memorandum of Understandings, and other organizations as requested.

The next ACARES meeting is Thursday, October 13, at 7pm at the Cherry Creek ESC building on the Southeast corner of E. Union Avenue and S. Yosemite Street. The address is 4700 South Yosemite Street, Greenwood Village, CO 80111. Click here for a Google Map.

A.C.A.R.E.S. stands for Arapahoe County Amateur Radio Emergency Services. We are one of the largest and fastest growing ARES groups in the state of Colorado. We are proud of the service we provide and are always looking for good people and new opportunities to serve our community. To see our upcoming events view our Calendar

Where were you on 09/11?

This is the 15th anniversary of the terrorist attack that has become to be known as simply 09/11. And while the focus of the tributes is appropriately on New York and the thousands of lives lost and lives saved by the many heroes that day, we should never forget the contributions here in our own back yard.

I was the Emergency Coordinator of Arapahoe County ARES at the time. I spent the evening of 9/11 in the Arapahoe County EOC after I finished work. I was surprised as to how few people were there considering what had just happened and the rumors that were going wild during that time (an example was that the building downtown called the World Trade Center was next to be targeted). The Undersheriff, the Emergency Manager plus one other deputy were the only ones there. The Undersheriff was planning security for a flight of much needed blood to be flown to New York. Otherwise, the county was quiet.

The following day, the calls started coming in. Since all flights out of DIA were grounded, shelters needed to be opened and communications were needed for these shelters. The Red Cross Communicators were understandably overwhelmed with requests for communicators.

The word went out to the district and many stepped up to help man the shelters. As we are all aware, extraordinary times call for extraordinary measures. ARES members did more than communicate. Many drove vans to pick up stranded passengers from DIA to transport them to shelters. Others helped out in the shelter doing other duties other than communicate.

The members I am most proud of went above and beyond. Some took the stranded passengers on tours of Denver. Some took stranded passengers to the movies. All ARES members made those stranded feel welcome here.

As ARES members, it is important to remember that the actions we take here will have a profound effect on the lives of citizens here but also have an effect on citizens around the country and around the world. Please remember that when we are called to assist either for a planned event or a disaster.

It certainly did on the days after 9/11.

Archive of Newsletters now online

N0POH provided us with some archived newsletters that we have posted now on a "Newsletters" page. These are definitely worth the read! They are historical, informative, and entertaining! It amazes me, especially as your new EC, how Alphonse Karr really hit the nail on the head when he said "The more things change, the more they are the same." If you have other newsletters or materials of interest to the history of Arapahoe ARES please send them to N2NWA or KD5DKQ.

D22 Newsletters from years gone by

Wayne, N0POH, was going through some files and found some newsletters dating from 1988 to about 2006 and has scanned them into a single 37 page PDF file that can be downloaded: D22 Newsletters 1988 to about 2006. Thanks to Wayne for scanning those for us!

146.640 Live Feed

The 146.640 Live Feed is online again. Our new house offers excellent coverage without the need for an external antenna so this will stay up "Live" during inclement weather. The link is here and can be found at the bottom of the Weather Links Module on the right side of this page. If I lose utility power the feed will go down and not come back up so let me know, EC at Arapahoe County ARES, if you find it offline or have any questions or comments.

National Emergency Communications Plan

The Department of Homeland Security just released The National Emergency Communications Plan. AuxComm is mentioned several times in the form of auxiliary communications resources or volunteers. Here is an example from page 80.  “Likewise, volunteer organizations such as community emergency response teams and auxiliary communications volunteers (e.g., amateur radio operators; also called Hams) play key roles in emergency communications and preparedness.” To download the PDF version click: 2014 DHS National Emergency Communications Plan.

National Interoperability Field Operations Guide

This copy was originally downloaded from the Safecom website and you may find the one below is better to use since Greg Pettis was kind enough to take the time to link and bookmark the pages for easier navigation on a PDA, smart phone, tablet or computer. It can be download via this link: National Interoperability Field Operations Guide v1.4

PDA Version of the AUXFOG

The Department of Homeland Security has released a PDA sized version of their Auxiliary Communications Field Operations Guide (AUXFOG) in PDF format.

Amateur Radio Emergency Service (ARES)

The Amateur Radio Emergency Service (ARES) consists of licensed amateurs who have voluntarily registered their qualifications and equipment for communications duty in the public service when disaster strikes. Every licensed amateur, regardless of membership in ARRL or any other local or national organization, is eligible for membership in ARES. The only qualification, other than possession of an Amateur Radio license, is a sincere desire to serve. Because ARES is an amateur radio service, only amateur radio operators are eligible for membership. The possession of emergency-powered equipment is desirable, but is not a requirement for membership. Although this is the serious side of the hobby, our members enjoy the work we do for our served agencies. To join, just complete these the forms in the ACARES Membership Packet and mail them to the address on the membership application.


The "Official" ACARES shirts are available for purchase by members. The *new* preferred color is Khaki and has the multi-Color ACARES logo embroidered. These sharp looking shirts are locally done and take about 2 weeks for delivery. You may order yours at Monograms To Go, Inc. Their address is: 364 S. Chambers Road, in Aurora and they are on the NE corner of South Chambers Road and East Alameda Avenue. Click here for a map.
