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 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 at about 50 feet AGL at Fair Oaks Ranch.
           UHF: 444.9 (+) pl tone of  88.5. DR-2 using the upper UHF antenna on Tower Road. 


Hot News

NOTICE!  KARS meeting for May 7, 2020 will be conducted using Skype due to the Coronavirus epidemic.  The Skype link will be furnished shortly before meeting time.

Field Day will be discussed during this meeting.  The solution from ARRL seems to be, operate from home as Category D or E.  They will publish individual scores but so far, seem reluctant to combine these into a Club result.

See .   We think they could make a one-time exception which allows Field Day to be included in the list of ARRL contests.  Then Multi-Multi rules could apply.  

See<>. More on this as events occur.

The ARRL propagation forecast from Ted Cook, (K7RA) says, "There is broad consensus that Solar Minimum is ongoing this year -- or may have already occurred -- and that Cycle 25 will have no major change in the level of solar activity compared to Cycle 24.  Most forecasts and forecasters agree that the Cycle 25 peak is likely to be within plus or minus 20 percent of Cycle 24 and is likely to occur between 2024 and 2027."  See this link < > for the prediction from NOAA.

Our regular meeting place at the EMS building is setup with equipment for paramedic class.  This will last through July.  We still plan for future meetings though July to be held at the Boerne Police Station. The address for the Boerne Police Station  is 124 Old San Antonio Road in Boerne.  See Meetings, Training and Testing below for a picture of our temporary location.  A big "thank you" to Boerne Police Department.

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.
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.
DX This page will provide some "how to" ideas about working DX, tell how to find who is on the air and give you current propagation reports.  
LoTW and Club Log This subject discusses Ham software, how to get the rare one in the log and then how to get the confirmation.
