Field Day Rebirth

Field Day 2016 found me once again participating with NARC in the bucolic setting of Hollis, NH. I thought that last year was to be my last Field Day with the club as I was in the process of pulling up stakes and heading for Florida. However, I had the opportunity to head north the weekend before Field Day to drop my grand kids and their mom off for the summer. Once I realized the proximity to Field Day on the calendar, it didn’t take much lobbying from Fred, AB1OC to convince me to hang around for Field Day.

Prior to leaving for NH, Fred mentioned that the club would be operating from the Hollis-Brookline High School ball fields at the back of the school. The last time the club operated from Hollis was in 2012 when we were still putting up 70-foot towers and dipoles. Since that time, the club has downsized as far as ambition by switching to 40-foot towers using the falling derrick method to raise a single triband antenna and dipoles without anyone climbing. For those new to the club, the falling derrick approach came about from the 2014 World Radiosport Team Championship (WRTC) event that showcased New England as the Yankee Clipper Contest Club hosted 50-plus two-person teams of the best contest operators in the world. Several club members participated in setting up some 65 towers for the mid-July event.

For 2016, plans called for setting up the two towers similar to what was done last year. This time, however, the 40 SSB station was going to be beefed up with a 3-element Inverted Vee beam array. The club had tried such an array back in the 1990’s on 80 CW. It worked OK considering the elements were suspended from a drooping rope from a tree to one of the towers, hardly in line to benefit from a director and reflector. Fred opted to set up three, 50-foot telescoping masts with pulleys to hoist the elements up. I must admit that I figured setting up the array was going to be the long pole – err, poles – in the NARC tent. With twelve sets of guy ropes per mast I envisioned a rat’s nest just begging to be tangled. My pessimism proved to be unfounded as the masts went up without much of an effort from Murphy to mess things up. Kudos to all the folks who pitched in to pull it off smoothly. The array dominated the Field Day setup like a far-off DXpedition.

Also new for Field Day was the use of the new ICOM 7300 transceivers. I learned that many in the club have purchased what is an amazing rig with a very easy user interface (especially for me) and great phase noise performance at an uncharacteristically cheap price for ICOM. The low phase noise level translates to a lower level of interference from nearby stations. I had the chance to familiarize myself with the 7300 leading up to Field Day using the N1MM+ logging program so that I could avoid the panic at T-0. I operated 40 CW with an inverted Vee that was less than 100 feet from the end of the driven element of the 40 SSB array. I did not experience any noticeable interference.

Field Day 2016 had a number of welcome surprises for me after nearly 30 years of my involvement with NARC. To put in simply: a lot of new faces. The club has been growing by leaps and bounds since I left. (Hmm, that doesn’t make me look good.) I wore my NARC call badge in case anyone wondered who I was. I was happy to meet all the new “2 X 3” hams in the club and I hope I will be able to match faces to calls as time goes on. Other highlights were making contacts on satellite after a hiatus of several years, and a cool demonstration of amateur TV with the Pepperell club.

Field Day 2016 was a homecoming for me since I also had the chance to meet old friends from many past NARC Field Days. While NARC has operated at other sites over the years, Hollis has a rich history in the club. Back in the 80’s NARC operated from what was then an open field adjacent to Beltronics off the town center. I was new to NH back then and I was amazed at the level of participation to build four towers and set up 12 or more stations. The logistics of such an operation benefited from (1) a storage barn less than a mile away on Ridge Road; and (2) a large pool of 30-40 year-old Hams to put it all together. Using the call of our host Jim, N1NH, NARC was regularly in the top 10 finishers for Field Day.

The club grew steadily back then. When the field at Beltronics succumbed to rows of storage sheds, I looked around for a suitable site that would not require a large caravan of pickup trucks to haul our equipment. The solution was right under our noses: the field beyond the orchard behind our storage barn. This proved to be the idyllic setting for a Field Day operation that everyone liked. It did not take long for the club to ratchet up Field Day participation to 20 stations or more. NARC was off and running big-time, culminating in winning it all four years in a row during the 1990’s. One of the club members secured the call N1FD for the club to showcase our accomplishments.

With Field Day 2016, I see a rebirth of the enthusiasm I enjoyed in the past. The future of NARC Field Days will be driven by the new crop of hams in the club. It will most likely NOT be “your grandfather’s Field Day”. The goal is not to see if the club can match the glory years of yesteryear but to try new things. Alas, CW is fading in popularity in the face of the digital modes that have cropped up featuring 100% copy with near-QRP power levels. Maybe more stations running PSK or some other digital mode is worth trying. Rigs like the ICOM 7300 are a step in the right direction when it comes to mitigating inter-station interference. However, more can be done to quash interference when using the triplexers so that hassle-free copy is possible with simultaneous stations using the same beam. And it doesn’t have to be just better filters. Maybe some neat lock-out or synchronization schemes can be tried to make competing modes play nicely. Field Day should always be a venue to try new ideas, whether it be interference mitigation or some odd-ball antenna design. All you newbies in the club are far better with a computer than I will ever be. Time to use all those powerful tools and tackle these age-old problems.

Plans for N1FD Field Day 2016

Field Day Planning Team
Field Day Planning Team

Our 2016 Field Day Operation is rapidly approaching and our planning is in high gear! We have a great planning team working on Field Day this year and we have a lot of fun planned!

Field Day Planning - Site Layout at Hollis-Brookline High School
Site Layout at Hollis-Brookline High School

We will be operating at the Hollis-Brookline High School in Hollis, NH this year. We’ve been working on antenna plans and a layout for the site. We expect to be 7A or 8A this year. We are also going to try operating using a combination of Digital and SSB Phone from the SSB Stations.

Falling Derrick Tower and Beams
Falling Derrick Tower and Beams

We will have two towers with Tri-band Yagis for 20m, 15m and 10m and Inverted-V antennas for 80m/75m. We will be using triplexers and bandpass filters to allow the Tri-band Yagis to be shared across three transceivers as we did last year.

One tower will be used for CW operations as well as supporting the club’s 4 Element, 6m Yagi. The 6m Yagi will be rotatable. Jeff, WA1HCO and Tom, AB1NS have some cool plans for the 6m station this year which include Meteor Scatter and Es Contacts if we can catch openings on 6m. The CW tower will also have a 40m Inverted-V Antenna.

The other tower will be used to support the SSB/Digital stations on 75m, 20m, 15m, and 10m as well as an 11 Element Yagi for 70cm (more on this below).

Field Day Planning - 40m 3 Element V-Beam
40m 3 Element V-Beam Plans

We are planning some new antenna and station projects for our 2016 Field Day operation. We are going to build a 3 Element, 40m V-Beam Array using three 50 ft guyed masts. This antenna should perform comparably to a 40m short 2 Element Yagi at 70 ft.

Digital ATV Demonstration on 70cm

We are also planning a Digital Fast Scan ATV link between our Field Day site and the Nashoba Valley Club’s site. This will allow us to send and receive Live Digital Video between the two sites on the 70cm band.

20m Buddipole Ground Plane Antenna for GOTA Station

Field Day Station Test

Field Day Station Test - Field Day QTH

It’s almost time for the 2016 Field Day Event and we’ve been in high gear getting ready. We will be setting up at the Hollis-Brookline High School in Hollis this year. The Featured image for this article shows a satellite view of the site. We have already held two Field Day Planning Meetings and many club members have volunteered to help with our Field Day Operation for this year. You can read the latest about our Field Day plans in the Field Day Forum here on our site. Our club was very active in WRT2014 and we were able to purchase several of the WRTC station and tower kits from that effort.

In preparation for Field Day each year, we like to set up our station kit in our backyard to verify that all of our equipment is ready and in good working order. The first step is always to pitch the wall tent from the WRTC kit. The tent and the associated tables/chairs can comfortably hold 3 – 4 people.

Field Day SSB Station Test

We will be using the new IC-7300 Transceiver for Field Day this year. As you can see from the pictures from last year, we used an Elecraft KX3 Transceiver in 2015 along with an outboard KXPA100 100W Amplifier to bring the station up to 100W and Elecraft’s PX3 Panadapter. The either of these combinations makes a great 100W Field Day Station as does any good 100W transceiver that can be operated from 13.8Vdc power.

We’ve also used a Behringer HA400 four channel headphone amplifier (the unit on the right on top of the power supply) with our Field Day setup. This enables connection of a total of 4 sets of headphones to the station – one for the operator, one for a logger and two more pairs for folks to listen in on the fun. Our club has been doing a great deal of outreach to encourage new HAMs to join the hobby and we built this setup so that some of the new folks can listen in on our operation more easily. We will be using a Heil Pro 7 headset to operate and we will have 3 sets of Heil Pro Set 3 headphones for others to use. The Heil gear is very comfortable, light weight and sound great over the air.

N1MM+ Logger

We will again be using the N1MM+ Logger for Field Day. It is very easy to set up N1MM+ to work with the IC-7300 or the KX3. We will be doing an N1MM+ demo and training at our June Tech Night session to help others in our club to get going on the N1MM+ logger.

Generator Test
Generator Test

One of the many great aspects of Field Day is that it requires those who participate to test their emergency equipment and field operating skills each year. Our club has a large generator and power distribution system that we all share for Field Day. We use our station test session as a reason to get our smaller generators out for a test run. We have a pair of Honda EU2000 generators which can be used together to generate quite a bit of power.

Our club has quite a bit of antenna equipment and we will be putting up two 40 ft towers and tri-band beams with Triplexes and Filters for our 20m, 15m and 10m SSB and CW stations. We are planning a 40m Delta Loop array for our club to use for 40m and we’ll also be putting up 40m and 80m inverted-V and dipole antennas.

I hope that everyone in our club will join in on the Field Day fun again this year.
