It seems like everyone (except for maybe Google) is downsizing these days. With that in mind, I thought that I’d downsize my Field Day. Instead of participating in the large 5A ARROW Field Day operation, the guys that hang around WA2HOM, our club station at the Hands-On Museum, decided to set up a much smaller operation.
Our first idea was to set up outside the museum. That seemed like it was going to work out until Quentin, KD8IPF, informed me that he couldn’t attend, as his wife was going to be out of town, and he needed to take care of his kids. I was concerned that without Quentin that we wouldn’t have enough operators to have two people there at all times.
Then, Quentin volunteered his backyard. This turned out to be a great venue. He has a fairly large, with a couple of big trees. Not only that, he lives next door to his mother-in-law, and she’s volunteered her trees as antenna supports. You gotta love a mother-in-law like that!
One of the advantages of downsizing is that you don’t have to spend so much time setting up. Instead of setting up antennas for five HF stations, a GOTA station, and a VHF/UHF station, all we had to do was set up antennas for our two HF stations. And, since we planned on using Quentin’s already-installed, multi-band dipole, we only really had one antenna to worry about.
That being the case, we decided that we really didn’t need to start setting up until noon on Saturday. Jim, K8ELR, and I actually arrived about 11:30 am, and that proved to be more than enough time. Jim brought with him a 40m dipole and a 30m, end-fed half-wave antenna, while I brought my BuddiStick. We quickly decided to put up the 40m dipole, and by 1pm, we were already on the air.
A Tale of Two Antennas
Of course, it wasn’t really as simple as all that. When we started operating, the two stations interfered with one another something terrible. So much so that my KX-1 was even causing Quentin’s LDG autotuner to retune itself when I transmitted.
The problem was that the 40m dipole and the multi-band dipole were running nearly parallel to one another. I should have known that this would occur, having been involved with more than a few Field Days by now, but it never even crossed my mind.
Fortunately, the solution was relatively simple. All we had to do was to take down the multi-band dipole and hang it from two different trees, one of them in the adjoining yard. After we did this, the two antennas were nearly perpendicular to one another, and the interference just went away. The phone station could not hear my little peanut whistle signal at all, and while I could hear the phone station transmit, it really didn’t affect my ability to make contacts.
I really didn’t think that this was going to work, but Ovide, K8EV, was quite confident that it would. I was the one that ate crow.
Did You Really Use a KX-1?
So, I can hear a lot of you asking, “Did you really use a KX-1 for Field Day?” Yes, I did. Our original idea was to run all QRP. The thinking behind this is that if you run all QRP, then you get 5 points for each QSO.
The other reason for doing this is so that we could run off batteries. Quentin had access to two, 66 Ahr batteries, and we’d planned to use these two batteries as our power source. I figured that with the 12V gel cell that I have for my KX-1, that would be plenty of power.
Unfortunately, that didn’t work out. Quentin and Ovide were just not having any luck making any contact at 5W—and consequently not having much fun—so they decided to increase power. That blew our QRP multiplier, but what the heck, it multiplied our fun factor.
Plenty of Power
As it turned out, just one battery provided plenty of power for the phone station, even at 100W. Granted the station was off the air from about midnight Saturday through 9 am Sunday morning, but there was apparently plenty of juice to power that station throughout the entire 24 hours.
Likewise, my little gel cell provided enough power for the KX-1 over the 12 hours that I had it on the air, and I’d guess that the charge would have been good for the entire 24 hours. I have yet to run down that battery so low that it failed to power the radio.
What Did We Learn?
We learned several things from this Field Day:
- A downsized Field Day can be as much or more fun than a full-blown operation. Without a big crowd vying for just a few positions, everyone got a chance to operate. Plus, setup and teardown times were a lot shorter.
- You still have to pay attention to your antennas. If we’d done a little more planning and thinking about our antennas, we would have avoided the interference we experienced and possibly even been able to run QRP on phone.
How, you might ask? Well, if I’d thought about rigging up some kind of wire beam or a Moxon beam for the phone station, they may have been able to run QRP and still make contacts. This is certainly something to think about for next year. - The batteries worked great. Not only did they provide enough power for a 100W rig for more than 12 hours, they were quiet. The noise of a gas-powered generator can really get on your nerves over the course of a Field Day.
- While I probably wouldn’t want to run the KX-1 in a big DX contest, it worked pretty well for Field Day. I made more than 160 QSOs with it in about 12 hours of contesting.
So, What About Next Year?
Since it’s never too early to plan for next year’s Field Day, we’re already kicking around a few ideas:
- Find a campground to have Field Day at next year. The upside is that the scenery might be nicer. The downside is that we might not have the nice antenna supports, errrr trees, that Quentin has in his backyard.
- Be more competitive. Joe, N8OY, came by late Saturday evening, and racked up a bunch of points for us on 20m CW. He suggested that we organize some of the local hot-shot CW operators around here and set up a real competitive operation. The upside is that scoring a lot of points is fun. The downside is that being competitive excludes the less-experienced operators.
One thing is for sure. Running a smaller Field Day event in no way diminishes it as the “quintessential” amateur radio event. We still enjoyed all the camaraderie as well as all the technical aspects of Field Day. Now, I can’t wait until next year.

The Sangamon Valley Radio club has ran 100watt battery powered field days for at least 25 years. Staab Battery in Springfield Illinois has kindly provided us with batteries all of those years.

I wonder if CW and QRP go together a little better than using QRP on phone? I heard lots of poor operating practices on phone during Field Day. Lousy phonetics, not offering a call-sign when asking QRZ, mixed-up timing, and other things seemed to doom the phone guys’ ability to log QSOs. The CW crowd just seemed to chug along and log contacts. I’m not saying the CW guys are a better group of operators. Maybe they have fewer options? So going into a pile-up with five watts on phone might not be as successful as using CW and that same five watts? I’m sure all the parts need to be there from paddle/mic to antenna. I’m just saying, I wonder? de Bill, NA8M

If you want to set up a QRP field day, you might just get me to fly in to help with it. I’ll bring the FT-817nd. A 2 element beam for 10 and 15 meters is cheap to make and real easy to put up. VHF antennas are even easier and you’d be surprised how many vhf-uhf contacts you can make with a decent antenna.

Well, that might be very cool. It would be great to have a VHF/UHF station.
