 San Antonio Hams » Chaparral ARC
Oct 30

Location: Hill Country State Natural Area – Bandera County, TexasBandera_2014_buckle

When:    6th and 7th of January 2018

Description: 25k, 5ok and 100k Ultra-Matathon

It is that time of year, to start marking your calendars and making preparations for the 16th Annual Bandera 100k Ultra-Marathon held at Hill Country State Natural Area in Bandera County.

Tejas Trails Communication Group – Coordinated by Hill Country REACT with support of Highland Lakes Amateur Radio Club, Chaparral Amateur Radio Club, and other dedicated Amateur Radio Operators from San Antonio, Austin, Houston, Kerrville and other locations throughout the state, have supported and provided communications for this event the past 12 years. The team is responsible for communications, health and welfare, tracking, and occasionally Search and Rescue. We also manage the parking at o’dark-thirty to get the 900 runners and crews parked and to the start-finish line on time.

There is little to NO cellular coverage at this venue, thus the participants, families, crews and promoters rely on the skill and expertise of the Amateur Radio Community.
We have 4 Aid Stations/Break Points, Net Control and Rovers to cover for approximately 20 hours.
This event typically requires 14 – 18 Amateur Radio Operators in a situation that is similar to what an Emergency Communications Operator would experience in a disaster zone. Remote operations little to no permanent infrastructure. Bring it, work it, test it, and enjoy it!

Horseback Hams are also needed and greatly appreciated by the participants.

If you know of a youth organization that needs public service hours, this is a great opportunity to get them in.  We have numerous positions from assisting the communications team to helping serve the runners at the aid stations.

UHF, VHF Voice and Packet communications are involved in this event.  We have been wanting to deploy a Broadbrand-HamNet but research and development has stalled. Anyone with experience in this area is encouraged to help us out.

The 2015 communications team, for the running of the Cactus Rose 100, was supported on-air for 31 hours by five members of Hill Country REACT and one member of the Chaparral Amateur Radio Club.

CR100 has been a event on the public event schedule for 5 years now, with Hill Country REACT as the lead with participation from numerous individuals and organizations.  Our involvement with Tejas Trails is going on about 11 years, between the Bandera 100K and Cactus Rose 100.

Both events are held on the Hill Country State Natural Area in Bandera County Texas. Continued support and dedication from members of Hill Country REACT, Highland Lakes ARC, Chaparral ARC, Hill Country ARC and numerous individuals of various affiliations continue to make these events a communications success which bring awareness and appreciation to the Amateur Radio community.

 Hill Country State Natural Area is a 5,400 acre facility with over 34 miles of equestrian, hiking, biking and running trails from flat and smooth to 45 degree rocky climbs.

The environment and terrain at HCSNA creates numerous challenges for communications. Cell phone coverage is nearly non-existent with the average smart phone, the nearest permanent ham repeater is over 20 miles away and behind a range, and simplex vhf/uhf communications can be finicky.

At most events we deploy a portable repeater onsite, but due to the impending weather forecast the decision was made to work strictly simplex and not attempt this to expedite demobilization. At the remote aid stations, HT’s were supported by mobile units positioned nearby.

The Chaparral Amateur Radio Club is offering a technician-level license class September 19 and 26 (2015) at the office of Guadalupe County Emergency Management Office, 415 East Donegan Street in Seguin. It will be held from 9 a.m. to 5 p.m. each day. A license exam will be given before the end of class on September 26th.

This is an intense two-day course that covers all of the material necessary to pass the exam to obtain a Federal Communications Commission Amateur Radio Technician class license.

Participants will need a “Technician Class Manual” (2014-2018) by Gordon West, available from www.w5yi.org/catalog for $21.95.

There is no Morse code requirement for this license.

The technician class license is the entry-level license of choice for most new ham radio operators.

The license gives access to all amateur radio frequencies above 30 megahertz, allowing these licensees the ability to communicate locally and most often within North America. It also allows for some limited privileges on the HF (also called “short wave”) bands used for international communications.

For more information, contact Steve Leibovitz at sandpiper986@yahoo.com or 830.660.9514, or Max Brandenberger at maxb@kd5sfk.com or 512.470.5431.

The Skywarn Operators at the Austin-San Antonio NWO are in the process of updating our files and call-up list. Recently we have found the EC’s, Skywarn Coordinators and Net Controls have changed drastically in the various counties we serve.
It has also been found that several repeaters used in the past to contact and monitor Skywarn operations have changed or are no longer functioning.
If someone from each county could please e-mail me the contact information, frequencies and other pertinent information for ARES and Skywarn it would be greatly appreciated.
Also be advised that we have created a Facebook page and Twitter account to help get the word out. Feel free to like or follow to stay up to date with our operations.
Thank You, Louis – K5STX

Title: 2013 AERC Heart of the Hills Endurance Event
Location: Hill Country State Natural Area – Bandera, Texas
Link out: Click here
Description: The AERC Heart of the HIlls is a 25 and 50 mile equestrian endurance event that test the horse and rider.
Hill Country REACT as well as members of other organizations have provided Amateur Radio Communications, Safety and Tracking for the last 3 years. Amateur Radio has become and important part of this event due to the remoteness and terrain, and our familiarity of the facility. In being able to consistently and accurately track the competitors at various checkpoints, we have become more than just a safety net!

Any licensed Amateur Radio Operator with interest in Public Service and Emergency Communications are invited to assist with this event. Events like this are the best way to test equipment and hone skills that would be useful during a disaster deployment.

This years event will be two days, with the major emphasis and need on Saturday March 2nd, as the largest group of competitors will be on this day. Sunday March 3rd will be the same course for the most part, but the expected group is smaller.

Communications for this event is typically VHF simplex voice and the utilization of a event specific packet spreadsheet utilized for tracking.

We need 8 – 12 operators for Saturday March 2nd and 5 – 8 on Sunday!

For more information or to sign up, contact Louis – K5STX at k5stx@arrl.net

Thank You!
