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.  Here is a newspaper report about KARS Field Day, 1991 from KARS past president, Mark Rosier, KE5GL.

The COVID-19 pandemic-modified ARRL Field Day rules from 2020 will continue this June with the addition of a power limit imposed on Class D (Home Stations) and Class E (Home Stations-Emergency Power) participants. The news from the ARRL Boards Programs and Services Committee comes as many clubs and groups are starting preparations for Field Day in earnest. Field Day 2021 will take place June 26 27.

This early decision should alleviate any hesitancy that radio clubs and individual Field Day participants may have with their planning for the event, said ARRL Contest Program Manager Paul Bourque, N1SFE.

For Field Day 2021:

  • Class D stations may 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

Field Day 2020 - was conducted using distributed operation, mostly from home due to COVID-19.  One might expect less activity than usual; not so.  Once again the Amateur Community showed it could adapt to any situation and provide reliable point to point communications through out the US and Canada.  Bands were barely Okay on Saturday and hopping on Sunday with many stations, mostly home, on the air.  We used the KB5TX VHF (146.64 MHz) repeater to keep track of one-another and the progress being made.  While all missed the face to face social contact, all reported having a great time.  One reported doubling his lifetime HF contacts during the 24 hour operating period.  This achieved a major objective of KARS; to enhance the HF operating skills of the membership.

ARRL has published the official scores for individuals and for KB5TX in the December 2020 edition of QST.  Forty-Four percent of total contacts were made using CW.  The total score for KARS is 4530, from six participants.  See for the article from QST and then look at for the individual scores.  These were not immediately apparent until Don -- KI5AIU did a search for KARS entries to arrive at the table shown below.  We still don't know where we scored within the South Texas Section but we are working on it.

Al - K5NOF, CW, 300 QSO's, 1350 points from his home station using N1MM to key his ICOM rig.

Mark - N5YZV, FT8, collected 80 QSO's!  These 80 contacts were done from his 1B station (battery/solar running an FT-991a and a Raspberry Pi) at 5W, using a Pi4.  Mark gets a 5x multiplier for QRP/non-commercial power operation for 1000 points. Marks power was so effective that solar kept his batteries topped off.  He never dropped below 12.9v on the battery.  Pretty amazing when you consider he was using an all band, all mode rig.

Don - KI5AIU, FT8, 119 QSO's  for 726 points from his home station.

Tim, W5ATG, 128 QSOs, FT8 for 562 points.

Marsh, WA5UBO, SSB, used solar charged battery to rig and laptop to make 106 QSO's for 462 points.  He was on the way to more until he paused to rag-chew with old friend in Ponca City, OK.  

Ben, K5AYR, FT8 45 QSOs for 430 points.

Pictures from Field Day 2020 -- will be posted as they become available.

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, Marks 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 Als 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 its 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
