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. Since the first ARRL Field Day in 1933, radio amateurs throughout North America have practiced the rapid deployment of radio communications equipment in environments ranging from operations under tents in remote areas to operations inside Emergency Operations Centers (EOCs).  

KARS has been participating in Field day since 1981.  Operation is a contest between ourselves and other ARRL clubs in the US and Canada. Our Field Day location is the K5NOF ranch located at 48 Rust Lane, Boerne, TX. The location is large enough to allow multiple radio stations on the air at the same time with covered locations for the operators and stations; we have had as many as seven going at the same time. These allow us to operate CW, Digital and SSB with little interference between one and another.

So how did we do this past Field Day - 2017.  Not that bad.  We were able to use the "Foxtrot" classification due to our relationship with Kendall County EOC and having an EOC unit on the Field Day site.  With five transmitters, we scored third of 13 Nationally, with 808 QSO's and a score of 3716.  I suppose it is all a matter of priorities.  Ours is to go for a reasonable score while offering operating opportunities to our new Hams.

Field Day is always held over the last full weekend of June.  This year, Field Day - 2018 will commence at 1800Z (1300 local) on June 23 and end at 1759Z (1259 local) June 24.  Setup will commence at 1300 local on the 22nd.  Operation will be from the Kendall County EOC trailers and from other locations at our Field Day site.  All operators should try to walk the property beforehand to obtain a good idea what they will need for setup.  A BBQ lunch will commence around Noon on June 23 during which we will sort out a schedule of who does what and when.

Digital and CW contacts count the most for score. So we generally have a core group of CW operators to assure a respectable score. At the same time 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 will include you in the CW schedule if you know how to "pound brass." Otherwise will find a place for you on a key board or at the microphone.  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
