Sunset, Field Day 2013
Since 2009, OCRA and the DFMA have joined forces to produce a combined Field
Day operation. Field Day is an annual, national, emergency preparedness and
communications exercise. It is essentially framed as a contest where radio
contacts with other stations across the country earn points. The results of
this collaboration have been spectacular. A few years ago we earned the #2 spot
in the nation. In the previous three years, we came in third. This is out of
well over 2500 entries. Since the Covid Pandemic, we've changed our operating
model some and now include home stations. We have also changed from QRP (5 watts max)
to 100 watts and now use commercial power where in the past we were wholly battery
Field Day also has many educational and social components. It gives new hams
an opportunity to operate in the HF bands in the presence of much more
experienced hams. The setup and use of high-quality antenna systems
demonstrates how even with only limited transmitter power, it is possible
to communicate across the country. Socially, hams get to know other hams
in a setting rather different from the monthly meetings. Excellent food
rounds out the experience.

Field Day 2023 Logistics
I wanted to update everyone on the upcoming OCRA/DFMA Field Day activities.
Most of this has been covered at the last DFMA and OCRA meetings. Much of
the traffic with regards to Field Day takes place on the OCRA-DFMA email

1. Setup: 8am-6pm Friday, 6/23
2. Final Setup: 8am-2pm Saturday, 6/24
3. Operation: 2pm Saturday 6/24 through 2pm Sunday 6/25

All hams are welcome to participate in as much or as little as is desired. All are welcome to chip in.
If you don’t have much time, at least drop by and see this impressive operation put on by our clubs.
Some important comments on food and drink. The potluck dinner initiated in 2015 is still going strong!
will provide lunch around 11:00 for the benefit of people doing setup work Friday morning. Thank you John!
Potluck Dinner at about 6:00pm. Wilson, W4BOH,
will smoke Boston Butts for all who sign up
for the associated Potluck Dinner.
This means you should sign up and be willing to bring
something. (Wilson needs a count to do his part.)
If you plan to attend, send
email to John, KM4MDR, who is coordinating this
dinner (jsboone at msn dot com).
Let us know you are
coming (your name and call), what you are bringing and
how many are coming in your party (spouses are invited!).
Water and Gatorade will be provided. You may, of course,
bring you own beverage (but provide your own cooler if
You are on your own for breakfast and lunch.
Dinner at about 5:00pm.
Dave W4SAR - will provide pizzas for the Saturday dinner (Ed Neely W4AEN has volunteered to pick up the order and deliver to site)
Breakfast/Brunch at about 9:am. We will use the grills to provide pancakes, sausage (and a veggie version), maple syrup, juice, etc. The food for this is being donated by Dee, KU4GC.
Drink: Just to repeat the message imbedded in the text above. There will be water and free Gatorade available during the whole three day event. It is important that you stay hydrated, especially if we have a hot weekend, as we often do this time of year.

Safety Guidelines for Field Day
We will be operating in the open in a rural setting. We will be dealing not only with outdoor concerns, but also dealing with electricity, RF energy, power cords, and pointy pieces of metal. So to keep it safe, please mind the following guidelines:
- Be prepared for any kind of weather, our Field Days have had anything
from muggy, oppressively hot days to chilly nights. Bring
adequate clothing for the conditions.
Watch out for each other, and be alert for the signs of heat exhaustion or heat stroke. If someone is feeling nauseated, feels faint, seems slow to respond or is not responding appropriately to questions, or feels chills when it is hot, that can be heat exhaustion. Get them into a cool place and have them rest and drink fluids under observation until they recover, and urinate at least twice. If they FLUSH RED AND STOP SWEATING, that is a red flag for heat stroke, cool them down immediately by any means externally - ice packs, cold water- and call 911, this is a dangerous condition.
Shelter is very important, a large tent or an elevated tarp will protect you and your equipment from direct sun and rain.
Stay hydrated! We will have a bottomless supply of water and pots of Gatorade, indulge yourself!
Be aware that the brush lines may have Poison Ivy, watch where you step. Ticks and mosquitoes are a couple of the unlikeable examples of wildlife you will run into. Use a good quality insect repellant containing DEET to keep them off. Be sure to wipe any DEET off the insides of your hands as it dissolves some plastics, and you might etch your fingerprints into your microphone.
When raising antennas, first off, be sure you have adequate help. If you are stacking metal, helmets and gloves should be worn. If shooting pilot lines with a bow and arrow, have a spotter to keep the target area clear of personnel.
All guy lines and feed lines should be clearly marked with fluorescent flagging tape or surveyor’s flags. At night, guy lines at risk should be marked with “glow sticks”.
When moving heavy stuff, don’t be shy about asking for help.
All wiring harnesses must be fused. All stations will be securely connected to grounding rods.
Band Captains are urged to keep both a fire extinguisher and a first aid kit at their operating position.
In the event of an approaching electrical storm, shut down the station and disconnect the feedlines. If lightning, high winds, hail or other hazards are approaching, most likely the best option is to take shelter in the garage or your vehicle.
Report any injuries immediately.
