Kendall Amateur Radio Society



Field Day

Field Day is an annual amateur radio exercise, widely sponsored by IARU regions and member organizations, encouraging emergency communications preparedness among amateur radio operators. In the United States, and in Canada, it is typically the largest single emergency preparedness exercise in both Countries, with over 30,000 operators participating each year. Field Day is always held over the last full weekend of June.  KARS has been participating in Field day since 1981. 

The COVID-19 pandemic-modified ARRL Field Day rules from 2020 continued for FD 2021 this June with the addition of a power limit imposed on Class D (Home Stations) and Class E (Home Stations-Emergency Power) participants.

For Field Day 2021:

  • Class D stations could work all other Field Day stations, including other Class D stations, for points. This year, however, Class D and Class E stations will be limited to 150 W PEP output.
  • An aggregate club score will be published — just as it was done last year. The aggregate score will be a sum of all individual entries that attributed their score to that of a specific club.
  • KB5TX scores will be posted as soon as they become available from ARRL.

Pictures from Field Day 2020 -- are shown here.  Pictures for 2021 will be posted soon..

Field Day 2019 - and we are ready to go as the alternate EOC for Kendall County, TX.  We have the Emergency Operations Trailer on site with two HF stations installed connected to  two Carolina Windom OCF dipoles, also a VHF/UHF FM & Fusion Digital radio, and 700/800 MHz comms with Boerne Dispatch. 

Pictures from Field Day 2018.  At left, Al Walters K5NOF ran the 40m CW station from his office in the house and used his STEPP/IR tunable vertical.  At center, Marsh WA5UBO ran 20m SSB from under the awning of his Casita trailer with help from newcomers Brad Peace KG5YOX and David Walden KD5JVH.  Kendall Co. emergency coordinator and David Walden run SSB from the EOC trailer.






K4OCE & Clan

Steve Schwarz


The Rosier clan was all there, Bob, Mark, Mark’s brother Tom and a grandson too at left.  Bob K4OCE pulled his weight on 20m CW most of the time.  Steven Schwarz set up a digital mode station in the barn.  From there, he tapped Al’s offset-fed (Windom) mult-band dipole.  Steven started out trying to use FT8 and quickly got frustrated (as I did), and moved over to PSK-31 mode: Dave Moore set up and ran a 6m station in the barn complete with a laptop computer with a second monitor running FT8 digital capability.  He was unable to deploy the 5-elemet Yagi this year because it’s now on top of his tower at home.  But 6m sporadic E has been so hot of late, that one does not need much of an antenna when the band is open.  So, he brought a Par Electronics OmniangleTM halo, and mounted it 10’ off the ground on a TV mast.  Dave was able to work a number of stations without difficulty on FT8 and SSB.

Digital and CW contacts count the most for score and in 2018 we had a core group of CW operators to assure a respectable score. Total CW contacts this year totaled 413.  Digital and SSB for another 243.  Total score for this year is 3124.   This placed KB5TX third in STX, Category F.

We hope to do better this year and we did.  Total CW contacts this year 290.  Total digital 132.  Total Phone 42.  QSO points 886 for a preliminary score for 2019 plus what we will receive for battery contacts, GOTA, Media Coverage and so on.  Our final score will be posted here when received from ARRL

We use Field Day to teach our new operators on-the-air skills, and try to provide on-the-air experience to as many as we can. We want our new members to operate! Interested in CW?  Join Al -- K5NOF.  No, you don't have to use his left-handed bug.  He'll have a key or paddles for you to use.  Questions?  Email Al at
