CW Ops Using Winkeyer and a Decoder

Ira (KC1EMJ) and I helped set up the IC-7300 80, 15, and 10m CW station. We were short a CW operator.  Having my license for only 8 months with over 1000 SSB QSOs and zero CW contacts in the log I wasn’t a CW op but the station was available and the field day clock was running. My ability to copy is improving but very limited. On the run up to Field Day I had some experience with N1MM, Fred (AB1OC) added a WinKeyer and loaded his macros, and I had CW Skimmer already installed on the laptop. What more could I need?

It only took a few minutes to get the ICOM IC-7300 and CW Skimmer setup for reliable decoding. It was exciting when the decoder finally started displaying “CQ CQ FD DE CALL-SIGN” for each station I tuned in. I have included a simulated display showing a decoded message.image001 I was in business! Or so I thought.

With Search and Pounce selected, the WinKeyer was setup so the laptop keyboard’s F1 key was QRL?, F2 the exchange (class and section), F3 TU for “thank you” and so on through F9.  I assumed one would start with F1, and progress to F2, and then F3, what is QRL anyway? After decoding a “CQ FD call-sign” and entering the call into N1MM I hit F1, and then decoded a “don’t say you do not hear me”.

I moved up the band and tried it again with the same result. It was great I was making contacts, but not so great they was throwing bricks. A quick check with Mike (K1WVO) I found QRL is “Are you busy?”. As a Phone op I had never used QRL, we just ask “is the frequency is in use”. Soon I was responding with N1FD instead of QRL? The Caller returned his class and section.

With his call entered into N1MM it was easy to send his call sign with a tap of the F5 key, F2 for 7A and NH, and after his TU I would send a TU and QSY to the next station and repeat the process. It had transitioned from real exciting (meaning a bit stressful)  to real fun fairly quickly.  The lesson I learned is to take the time to understand the message stored behind each “F” key even when time is short and the contest or Field Day has started.

The experienced CW operators were using the same process that I was using with WinKeyer, N1MM, and the keyboard. The one difference  is they were decoding CW with their ears, and not a decoder.

It wasn’t long before I ran out of new stations to work. I switched from searching for stations in “Search and Pounce” mode  to “Run” meaning I stayed on one frequency and called CQ. The F1 key became CQ. It wasn’t long before I had a short run of 5-6 QSOs one right after another, but it quickly came to an end. There are few targets on 80m in the early evening and I worked them all. I was headed home just as the band was heating up at midnight… Next year I’ll take the midnight to daylight shift and plan to copy code with my ears…and not a decoder.

With a little practice, this form of operating is effective for contests and Field Day where the exchange is simple. The high rate you can add new stations to the log definitely makes it fun.

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
20m Buddipole Ground Plane Antenna for GOTA Station

Wayne, KB1HYL will be operating the GOTA Station again this year. We are going to put the GOTA station on 20m using a Ground Plane Vertical Antenna built from Buddipole Kit.
