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.  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. New Hams and experienced Hams will find a home with us.  Please come visit.  We are always looking for new members.  Your participation will be welcomed.

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

      VHF: 146.64(-)  pl tone of 88.5.  DR-2 at about 1970 feet above MSL on Tower Road.
          VHF: 145.19(-)  pl tone of 88.5.  DR-2 on the air for test at a temporary location and height in Fair Oaks Ranch.
           UHF: 444.9 (+) pl tone of  88.5. DR-2 using the upper UHF antenna on Tower Road.

Introduction  The seed for Amateur Radio was planted in the 1890's, when Marconi began his experiments in wireless telegraphy. Soon he was joined by hundreds.  This section tells you what we are about 129 years later.
Repeaters The 444.9 and 167.64 are both DR-2 machine are located at the Tower Road Site.  145.19 has been converted to DR-2 at a test location.  Click on "Repeaters" our current status.
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.
