Kendall Amateur Radio Society


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 current membership of around 70, and offer a variety of ham radio activities to amateur radio operators in the surrounding Texas Hill Country, and greater San Antonio areas.  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.

We are growing because we always look for new members and we mentor those new to our hobby.  New Hams and experienced Hams find a home with us because of our welcoming atmosphere. Once you meet us and see what we are about, we hope you will join. Your participation will be welcomed.  Please come visit.

We have 11 VE's and can test from Tech to Extra.  One does not need to be a member to test with us.  Follow this link for more information about testing. 

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

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 section tells you what we are about 131 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 Presentations.
Station Design for HF to 50MHz Our members operate stations from simple to elaborate.  We can give you ideas for yours.
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?  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.
