AC1EV Plans for 2020 Summer Field Day

AC1EV is operating 1E for Summer Field Day this year. I would have loved to operate in an ambitious club organized remote field day like we did last year, but Covid-19 social distancing requirements canceled that. I hoped to exercise my mobile setup and operate near saltwater, but again restrictions due to the virus made that difficult. I have a full house generator, so I will operate my home station on emergency power as class 1E. Here is how I am setup.

Power

17KW generator with 3 x 120-gallon propane tanks and Transfer switch

Antennas

K4KIO Hex Beam, 6 meters through 20 meters @33 feet and Alpha Delta 40/80 Dipole as an inverted V @ 45 feet.

AC1EV Field Day Station

Here is my shack in Tewksbury. I have an Icom IC-7300 with an Elecraft KPA500 amplifier along with an Elecraft KAT500 antenna tuner. Top that off with a Heil Pro 7 headset. The tuner allows me to select between the antennas. I have N1MM+ running on my laptop with two additional monitors leftover from my days as an IT Guru.

Field Day 2020 at W1AKI

Normally for the Nashua Area Radio Society, Field Day is a large, well-organized group activity of members, and many family members, setting up (and, later, taking down — safely!) at least a half a dozen stations, temporary towers with beam antennas, some interesting wire antennas, and our own emergency power grid. It’s a chance for members to try out transceivers and antennas and bands and modes that they may not have at their home QTH. It’s also a chance for members of the public to see what ham radio is all about and get an idea of what a temporary communications center hams can create in 24 hours in the event of a natural disaster or other emergency situation. So here’s what W1AKI Field Day plans are for 2020.

Life is What Happens When You’re Making Other Plans

This year, of course, things are different. They aren’t completely unprecedented — health care professionals and scientists have learned a lot from the 1918 Pandemic and, unfortunately, numerous others. But this is a new virus and a new disease, and the world is a much more crowded and interconnected place than it was over a century ago. Fortunately, we have technology undreamed of in 1918 to help science deal with the SARS-CoV-2 virus and the deadly COVID-19 disease it can cause.

So far, our modern, global communications infrastructure has held up well, and many people are very fortunate that they can continue working from home using the Internet and broadband communications channels. I’m extremely lucky that I’m one of them. And it’s not only the Internet, but technology like 3-D printing and small embedded computers have become additional tools that people have been able to make use of in this crisis.

Always Have a Backup Plan.  And a Plan C.  And Sometimes a D.  Maybe an E.

But what if that communications infrastructure does start to buckle under the load? As hams, and as members of the public, Field Day gives us a chance to think about how we would respond to that. And since we’re right in the middle of the pandemic ourselves, it forces us to look more closely at the changes we need to make to respond now. Does your “go kit” have a supply of face masks, hand sanitizer, and sterilizing wipes, not to mention soap and extra water for washing as well as drinking? Whether or not it did a year ago, I’m sure it does now!

So, this year, NARS won’t be setting up temporary towers in an idle athletic field. We won’t have a half dozen or more stations operating under the N1FD call sign with a small pool of gasoline-powered generators pushing our signals up to the ionosphere and back. We’ll be operating with our own call signs, from vehicles in isolated locations, from temporary stations set up by an individual or family member, or from our regular home stations.

Meanwhile, Back at W1AKI Field Day

I’ll be operating from home like so many others, with “100 watts and a wire” — an IC-7300 transceiver barefoot and an Alpha Delta 5 band fan dipole. (Okay, sorry, that’s more than “a” wire. And they’re mostly parallel, not in a wide fan. But it’s such a nice, traditional phrase. How can someone with a W1 call not love it? But I digress.) The 80m elements are extensions of the 40m elements with traps so that it is short enough to fit (just barely!) in my back yard.

My preparations so far have mostly included moving stuff around the shack so I can operate more comfortably, and updating the applications I use Firefox, N1MM Logger+, the DXLab suite, and DXLab’s various databases.

I won’t be using emergency power because I know that my generator works well (we have a few power outages here each year that give us a chance to test it; fortunately, power usually comes back in less than a half a day) and I’m willing to sacrifice the points to save fuel. (I’ll just have to make, what, 100 more contacts to make up for it? Oh, well, it is good practice.)

I’ve dug out some em-comm information and started refreshing my memory on message traffic procedures, that’s one thing I haven’t gotten to do before at Field Day. If I’m lucky, I’ll have time to finish tuning my antenna Saturday morning. My stretch goal is to get my son (an entomologist and microbiologist) on the air, but we’ll just have to wait and see how that goes.

It’s time to go double-check what the exchange is and get some rest.  I hope to see you on the air. 73 and take care of yourselves!

Going Mobile Five Stories Up

One of the enjoyments of ham radio is being able to throw your QRP rig into your car – at the spur of the moment – and heading out to a lake or along a river or to a mountaintop and Working the HF bands mobile from right where you are.

Field Day Mobile

For part of Field Day, I’m going to do something like this. I’m going to work “mobile” at another outdoor spot which some of us from NARS has done before  – the top of a five-story parking garage in downtown Nashua, New Hampshire. We jokingly call this our P*GOTA — Parking Garage On The Air.

Five Stories Up Over Beautiful Downtown Nashua

I do like to work from this site. It’s close by and easy to set up. There disadvantages, however, with all sorts of electrical noises and some reflection off of neighboring buildings. But for me, just being up 50 feet, to start with, is a big plus.

Mobile HF
The G90 On The Dash

I like to keep things simple and easy to use. My mobile transceiver is a Xiegu G90. It covers 160 to 10 meters with AM, SSB, and CW, from 1 to 20 watts. It has a built-in antenna tuner if needed. The maximum current draw is about 3 amps, so it works great off of the low-cost battery pack I use. The radio plugs right into the battery with a 12-volt adaptor; and I use a solar panel connected to the battery, keeping it charged. This really gives me the “off the grid ” experience.

The Antenna

The key to getting onto the air quickly mobile is to use a ham stick, screwed into a magnetic mount. I have one stick for 20 meters and another for 40.

Some say “mag mounts” really do not take care of grounding issues with HF like they do with VHF and UHF. However, I’ve found my set up works just fine. The SWR Sweep below shows the results with the mag mount on the roof. Before I put the magnet on the top of the car, the SWR level was over 5.

It’s always an adventure working “mobile” – running off a battery and solar – which gives you a chance to try all sorts of things. I suppose it would be more comfortable, sitting in one’s shack, with a large, powerful system and a finely tuned antenna …. but where is the fun?

I enjoy being up on an exotic spot and giving my CQ. And then telling the ham on the end, “my QTH is somewhere between High and Factory Street – downtown Nashua – November Hotel … five stories up”.
