Kendall Amateur Radio Society

KB5TX

Welcome to KARS

Welcome to the Kendall Amateur Radio Society (KARS). We are in the South Texas Section and located in Boerne, Kendall County, Texas around 30 miles NNW from Downtown San Antonio.  Our Club was formed in October 1980.  We have a paid membership of 55.  We are growing because we offer a variety of ham radio activities to amateur radio operators in the Texas Hill Country and the greater San Antonio area.  Additionally, we are growing because we have 11 VEs, and we routinely test from Tech to Extra.  Testing at KARS is open to any candidate.  Follow this link for more information.

ARRL Affiliation

We are an American Radio Relay League (ARRL) affiliated club and strongly support our National organization.  Our skills run from technology, to CW, SSB and Digital, working HF contests, chasing DX, 50 MHz, VHF and above.  Need help getting started in Amateur Radio?  Come see us.  We have Elmers willing to help in a variety of subjects shown below.  Come meet the subject matter experts.

 

We are not a repeater club, but we have one of the most capable system of repeaters in the Texas Hill Country.

KARS provides the following repeaters using the Club call KB5TX.  The VHF and UHF repeaters are Yaesu DR-2 analog/digital machines.

VHF: 146.64(-)  pl tone of 88.5.  DR-2 at about 1970 feet above MSL (110 feet AGL) on Tower Road.
 
VHF: 145.19(-)  pl tone of 88.5.  DR-2 at about 50 feet AGL on Tower Road.

UHF: 444.9 (+) pl tone of  88.5. DR-2 using the upper UHF antenna on Tower Road, with Wires-X.

KARS Net meets every Tuesday night at 7pm on the 146.64 repeater.  All are welcome.

This website is current a/o 24 May 22.  Latest content changes:  Announcement about our new meeting place at the Boerne Agricultural Museum, update to progress at Sisterdale, and our present plan for Field Day 22. 

Introduction  The seed for Amateur Radio was planted in the 1890's, with Marconi experiments in wireless telegraphy. Soon he was joined by hundreds; now thousands worldwide.  This page tells you what we are about 132 years later.
Radio Choices Many new to Amateur Radio wonder what radio to choose after their hand-held.  Here is information about Yaesu, Icom and Flex, along with links to others.  There is more about Flex in the Presentations folder.  Think about your first station as making an investment toward the future.  Try to make it a foundation upon which to grow.
Station Design for HF to 50MHz Our members operate stations from simple to elaborate.  We can give you ideas for yours and help you with your station design. See station layouts at N7RF, K5NOF and at K9ROD.
Station Design for VHF The Hill Country has many locations that are good for VHF and UHF.  With proper antennas and low loss coax, one can work much further than could be imagined.
QRP Want to get started in QRP?  We do that.  KARS past President, Bob Rosier - K4OCE, recently inducted into the QRP Hall of Fame, tells you how.
Weak Signal World & Digital New modes like FT4 and FT8 seem to be the fastest growing segment of our hobby.  See this page for FT4 and FT8 updates from Dave Moore, N7RF.  See this page also for and article about FELD-HELL by Mark Rosier, KE5GL.
Space See the Presentations Folder for information about ARISS --  Amateur Radio on the International Space Station.  The ISS call sign is presently NA1SS.  Downlink frequency:145.8 MHz.  Astronaut: Shannon Walker KD5DXB.  See https://www.ariss.org/current-status-of-iss-stations.html  for latest information.
Contesting and DX This page encourages one to get on HF and to work contests. You will find an ARRL link to nine pages of information how to begin contesting along with all the do's and don'ts.  This page also provides some "how to" ideas about contesting and working DX, plus how to find who is on the air and find current propagation reports.  
Software LoTW & Club Log This subject discusses Ham software, how to get the rare one in the log and then how to get the confirmation.  We can help you get started with LoTW and Club Log.
Repeaters The 444.9 and 146.64 are both DR-2 repeaters located ten miles north of Boerne on Tower Road.  145.19 is a DR-2 repeater temporarily located on Tower Road.  Work is underway to install a UHF repeater (444.925 (+) PL 88.5) at 150 feet AGL on the Volunteer Fire Department tower in Sisterdale, Texas, then move our 145.19 repeater to Sisterdale.
Field Day

Forget all you once knew about Field Day rules.  New for 2022 and onward:  power limit 100W, home stations can work others for score plus any one else.  Others can work as Class A, B, C.  Scores from individual operations may be combined into an Aggregate Club Score by simply including the club name in their submission.  See our present plan.
DIY (Do It Yourself) Our presentations folder became crowded, so we stripped out a collection of "Do It Yourself" projects developed by various members of KARS.  Informational items remain in "Presentations & Discussion."  Latest addition in DIY shows how KARS member Gavin, KI5MCD installed his Yaesu FT-857D in his Jeep Wrangler.
Presentations & Discussions We have frequent programs on a variety of amateur radio subjects.  Those most recent: Echolink Comes to KARS, Don Udel, KI5AIU.  Corky Sarvis, WB5CIT about Station Grounding. Don Udel, KI5AIU, "What is Winlink (and why should I care?)"
Meetings, Training and Testing See the link for our new meeting location.  We normally meet the first Thursday of each month, and can provide testing for Tech to Extra before the general meeting. We have 11 Volunteer Examiners.   Register beforehand so we know you are coming. See the link at left for requirements.  Contact Brad Peace - N5PBP for an appointment.  You do not need to be a member of our club to test.  We are open to all.
Links Here are links to various websites of interest.  New content, a compilation of various HP test articles and various Tektronics books on how to use various items of test equipment from Steve, W5SCL.   If you want to hear how ship to shore CW was done before the "night of nights" on 12 July 1991, check out the Maritime Radio Historical Society.
Community Activities We have a strong association with Kendall Co. EMS, the Kendall County Sheriff's Department and other organizations.  See our communication plan for interoperability with local agencies.
