Support for call signs up to 11 characters to support non-standard and compound call signs
The new version extends the length of the messages used for FT8 and MSK144 from 75/72 bits to 77 bits to enable the above features. As a result, there are compatibility issues between the v1.x releases of WSJT-X and v2.0 when FT8 and MSK144 modes are used. More detail about the new features and changes can be found here.
It is expected that the Meteor Scatter community (MSK144 mode users) will rapidly move to WSJT-X V2.0 so no backward compatibility features are provided for MSK144.
The transition for FT8 mode users is a much bigger problem. As a result, it is suggested that users test the new mode on alternative frequencies on the 20m band at 14.078 MHz and on the 40m band at 7.078 Mhz.
WSJT-X 2.0 FT8 Compatibility and Contest Options
The Advanced Tab in the WSJT-X v2.0 settings provides some options to help with compatibility between v1.x and V2.0. One must choose whether to transmit using the shorter v1.x or the v2.0 messages. If you are operating in the above mention “2.0” frequency areas on 20m or 40m, it’s a good idea to transmit using the 2.0 message format (check always generate 77-bit messages).
The new version of WSJT-X can decode both the shorter v1.x and the longer v2.0 messages simultaneously. The decoding will be faster on slower computers if you check the Decode only 77-bit messages option when operating in the v2.0 frequency ranges.
If you want to try the new v2.0 FT8 mode in one of the supported contests, you’ll want to check the appropriate Special operating activity option. If you are not operating in one of these contests, you’ll want to select None.
All you need to do to try the new version is to download and install it and configure the FT8 options. I’ve been running WSJT-X v2.0 rc1 in the 20m band in the 14.078 MHz sub-band this morning and have made about 20 contacts using the new format. The v2.0 software is working well.
There are some additional enhancements which will be included in WSJT-X v2.0. Here’s some information on these features from the WSJT-X v2.0 Quick Start Guide –
WSJT-X 2.0 has several other new features and capabilities. The WSPR decoder has better sensitivity by about 1 dB. Color highlighting of decoded messages provides worked-before status for callsigns, grid locators, and DXCC entities on a “by band” basis. Color highlighting can also identify stations that have (or have not) uploaded their logs to Logbook of the World (LoTW) within the past year. The necessary information from LoTW can be easily downloaded from the ARRL website.
Currently, several additional release candidates are planned for WSJT-X v2.0 as follows:
September 17, 2018: -rc1 Expires October 31, 2018
October 15, 2018: -rc2 Expires November 30, 2018
November 12, 2018: -rc3 Expires December 31, 2018
December 10, 2018: GA Full release of WSJT-X 2.0
Note that the release candidates will expire about 2 weeks after each new version becomes available. Also, its required that anyone who runs the Beta (release candidate) software agrees to report any bugs that they find.
We are looking forward to trying the new FT8 in the next digital contest which allows it.
The idea was to use an IC-7300 to create a 100W station and use a Solar/Battery combination to power the setup. Solar/Battery made us “legal” as a SOTA activation. We combined two 90W solar panels which I had with a MPPT solar charing system and two LiPo batteries to create the power system for the activation.
All of this gear was carried to the site and setup in about an hour. A 25 ft. section of LMR-400UF coax completed the station. The mast was guy’ed with rings which allowed us to turn the mast/antenna combination to point the Yagi in any direction.
Anita, AB1QB and Curtis, N1CMD Operating in the June VHF Contest
Between the SOTA/POTA activation and the June VHF contest, we made a little over 130 contacts on 6m. We did not have any real Es openings so most of our contacts were regional. Having the elevation provided by being on Pack Monadnock made us quite loud for the stations that could hear us. Several of our club members got on 6M and joined the fun. We did have a brief Es opening and managed to work a station in Alabama and one in Florida.
Mike, AB1YK Portable 6M
Mike, AB1YK has a much more portable 6M setup and used lower power to have some fun on 6M as well.
Al, KC1FOZ and Tom, KC1GGP Operating Portable
Al, KC1FOZ and Tom, KC1GGP put together a nice station and operated using battery power. Several other club members came out with portable station or to watch and have fun as well.
Our first SOTA/POTA activation was a lot of fun and Anita and I are looking forward to the next one!
Dave Merchant K1DLM, our Field Day chairman, is bringing some 21st Century radio and computer technology to our Field Day setup this year. There are several aspects to this new component of our Field Day plans including –
An on-site WiFi Network to enable using the N1MM+ Logger in network mode for sharing of log information, station activity, real-time scores, and messages
A central Score Board and Field Day Information Computer in our public information tent
2017 Field Day Site – Upper Field Layout
We will again be holding our 2017 Field Day operation at the Hollis-Brookline High School in Hollis, NH. We are planning on using the upper baseball field area as our main operating location. We have decided to add a third tower this year and locate it on a soccer practice field which is situated several hundred feet away from our main operating area. All of our antennas and equipment will lie within the required 1000′ circle but the third tower would situate those operating at that location away from the rest of our group. Dave’s solution to this problem was to set up a network and operate two Software Defined Radios (SDRs) at the lower site remotely from our location on the upper field.
Dave has enlisted Piece Fortin, K1FOP to be our IT Chairman for Field Day this year. Pierce has been instrumental, along with Dave, in the planning and testing of all of this new technology. Pierce and Dave have a great deal of networking and IT experience and knowledge and we could not have put together what is described here without them.
Dave K1DLM, Piece, Hamilton K1HMS, Mike Ryan K1WVO, Anita AB1QB, and I have gotten together multiple times to set up and test all of this new technology. I wanted to share some more about the equipment and the associated testing (which has been staged in the kitchen at our QTH – thank you, Anita!).
We began the testing process by setting up our 20m CW station.
20m CW Station Test
This station uses an Elecraft K3S Transceiver, a K1EL WinKeyer and the N1MM+ Logger running on a Windows 10 Laptop PC. We used this station to get our basic N1MM+ setup including our Field Day CW keying macros right.
40m SSB Station Test
Next came our 40m SSB station. This setup uses an Icom IC-7300 Transceiver and allowed us to set up and test N1MM+ on the fly audio macro recording and playback. All three of our SSB stations will have on the flyrecording and playback capability which will allow each of our SSB operators to record and use a custom set of audio macros.
Digital Station Test
Next came our Digital Station. This station uses one of the two remote Flex-6700 SDRs.
Remote Flex-6700 SDRs and Antenna Switch
Dave, K1DLM put together a really nice package for the two Flex-6700 SDRs and associated equipment which will be located on the lower field. He used a rack system to mount the two SDRs, power supplies, a three-band Tri-plexor, a set of bandpass filters for 80m, 40m, 20m, 15m, and 10m and a 403A 8×2 networked antenna switch. This setup allows either of the two SDRs to share the tri-band yagi or the 40m and 80m Inverted-V antennas on the tower on the lower field and operate on any of the 5 available HF bands. Antenna and filter switching automatically track the frequencies of the two SDRs making the setup simple to use.
Digital Station Second Display – SmartSDR & More N1MM+
The Digital Station’s remote SDR will be operated using a SmartSDR client running on the Digital Station laptop PC. This station will have a second monitor to better accommodate all of the windows associated with it.
Digital Station Main Display – N1MM+
The main display associated with the Digital Station will run decoders for all PSK and RTTY modes. The ability to decode multiple PSK signals simultaneously and multiple RTTY decodes are available. The Digital station also acts as the N1MM+ master station in our Field Day setup for all of the other stations which use N1MM+.
Satellite Station Test
Our Satellite Station 2.0 was also added to the test setup. It uses a MacBook Air laptop running MacDoppler to control the antenna rotators and the Icom IC-9100 Transceiver which are part of our Satellite Station. A Windows 10 Surface Pro computer is included which runs N1MM+ and provides logging and other network functionality for our Satellite Station.
GOTA Station Test
We also tested our GOTA station which uses the second Flex-6700 SDR and a FlexRadio Maestro to provide a more conventional “buttons and knobs” interface for our GOTA operators to use. This station will also have a laptop PC running N1MM+ for logging.
We also build and tested a Scoreboard PC. This computer will be located in the Public Information tent at Field Day and will be connected to a large display. It will show our real-time score, QSOs being logged as they are made and other useful information about our Field Day operations. This computer will also continuously play videos from our Video Collection and will provide access to IP video cameras which monitor the tower and equipment on the lower field.
Pierce, K1FOP and Hamilton, K1HMS Testing CW Stations
Our networked N1MM+ testbed contained at least one station of each type (CW, SSB, Digital, Satellite, and GOTA) that will be part of our Field Day setup this year. The Station Masters for the additional CW and SSB stations came by to test their setups using the test bed.
Field Day Networking System
The networking system which Dave and Pierce built is central to all of the technology described here. All of the gear is mounted in a single rack which will be located on the upper field during Field Day. The setup includes a Firewall/DHCP server, a commercial grade outdoor WiFi access point, a 4G LTE modem for Internet access, an Ethernet Switch, and a UPS power supply.
MoCA Data Link Cable
The upper and lower fields at our Field Day site are separated by several hundred feet. A thick line of trees between the two locations raised concerns about connecting the upper and lower sites using WiFi. Pierce came up with a great solution to this problem – we will be using MoCA Data Modems and RG6 Quad Shield 75 ohm Coax Cable to provide a 10 Mbps data link between the two sites. We tested the MoCA link using a much longer run of coax cable then we will need to use at Field Day and confirmed full 10 Mbps throughput.
N1MM+ Talk Window
Our networked N1MM+ setup will allow any station in our setup to send messages to everyone who is operating at Field Day. We can use this capability for important communications like “lunch is ready!” or “I need help from Pierce (our IT chairman) on the 40m SSB station”, or “The 6m band is wide open!”.
Our GOTA and Digital stations will be located together in the same tent and will provide our Field Day 2017 visitors to see and use 21st-century Amateur Radio technology to make contacts. We are expecting young people who participated in our High-Altitude Balloon project and from other local schools where we have done Amateur Radio activities to attend. In additional to being a learning opportunity for all of us in the Nashua Area Radio Society, we hope that the state of the art technology that we are using will generate interest among our visitors. If you are local to the Nashua, NH USA area, come pay us a visit during 2017 Field Day. We’d enjoy providing a tour for you and your family along with a chance to Get On The Air. Hope to see you at Field Day!
Every so often, I drive Fred’s truck into work and people ask me what that big antenna on the back of the truck is for. I explain to them that it is for Ham Radio. But the reply is usually, why ham radio – isn’t that outdated technology? We have cell phones and IM, etc…what do we need Ham Radio for? So I thought I would put down my thoughts as a relatively new Ham about why I enjoy spending so much of my time with Ham Radio.
Amateur Radio for Public Service
The number one reason we still need Ham Radio along with all the other technology we now have is for public service. When there is a disaster and cell phones, television, etc are all not working, Ham Radio operators provide the critical communication.
Ham Radio operators help locally to keep hospitals and first responders in contact with each other to help those affected by the disaster.
Hams also use our ability to communicate around the world on HF bands to help family members around the world to get in touch with loved ones affected by a disaster.
Ham Radio operators have been on the scene helping in every disaster from the earthquakes in Nepal to the recent flooding in California.
Amateur Radio Cube Satellites
Technology and the Maker Movement
I only became a Ham 5 years ago but many of my fellow Ham Radio operators got their license when they were in their early teens and used what they learned to launch their careers. Many have had very successful careers in STEM fields, all launched by their interest in Ham Radio at a young age. As technology advances, so does the technology used in our hobby. We even have a nobel laureate, Joe Taylor K1JT who is a ham. Joe has developed weak signal digital communication modes that let us communicate by bouncing signals off the moon!
As technology has advanced, so has the use of it in Ham Radio. Most Ham Radio operators have one or more computers in their shack. Many also have a software designed radio (SDR), where much of the radio functionality is implemented using Software, we use sound cards to run digital modes, which are a lot like texting over the radio, and we use the internet extensively as part of operating. We can also make contacts through satellites orbiting the earth and even the International Space Station.
Most hams love do-it-yourself technical projects, including building a station, home brewing an antenna, building a radio or other station component. In my day job, I am a program manager for software development projects, but its been a while since I have built anything. As a Ham I taught myself how to code in Python and about the Raspberry Pi and I built the DX Alarm Clock.
QSL Card from VK6LC in Western Australia
One of the coolest things about being an amateur radio operator is that you can communicate with other hams all over the world. Ham Radio is an international community where we all have something in common to talk about – our stations and why we enjoy ham radio. The QSL card above is from a memorable QSO with Mal, VK6LC, from Western Australia, who was the last contact that I needed for a Worked All Zones award. I must have talked to him for 1/2 hour about his town in Australia and his pet kangaroos!
Amateur Radio Map of the World
I have learned much about geography from being on the air and trying to contact as many countries as I can. There are 339 DX Entities, which are countries or other geographical entities and I have learned where each one is in order to understand where propagation will allow me make a contact. I have learned a great deal about world geography. Through exchanging QSL cards often get to see photos from so many areas of the world.
DXCC Challenge Award Plaque
Achievement – DXing and Contesting
DXing and Contesting provide a sense of achievement and exciting opportunity for competition. Many Hams work toward operating awards. You can get an operating award for contacting all 50 states, contacting 100 or more countries, contacting Islands, cities in Japan, countries in Asia, or anything else you can imagine. Each of these operating awards provides a sense of accomplishment and helps to build skills. Contesting builds skills through competition among Hams to see who can make the most contacts with the most places in 24 or 48 hours. Contesting also improves our operating skills and teaches us to copy callsigns and additional data accurately.
Teaching a License Class
Teaching Licensing Classes – Passing it On
Recently I have joined a team of club members who teach license classes to others who want to get licensed or upgrade their existing Amateur Radio licenses. Teaching provides a way to improve my presentation skills and also helps me to really understand the material that we teach about Amateur Radio. It is always a thrill at the end of the class to see so many people earn their licenses or upgrades.
Anita, AB1QB and I have spent a good deal of time this past year helping the Nashua Area Radio Club here in Nashua, NH USA as a way to give back to the Amateur Radio Service. Our work with the Nashua ARC has produced some of the most enjoyable and memorable times of our Amateur Radio experience.
Teaching Nashua Area Radio Club Hosted License Classes
In particular, our contributions to the work that our club is doing around helping people to earn licenses and introducing young people to the Amateur Radio Service has been most rewarding.

We recently produced a 2016 Highlights video about our Club’s activities and the club’s contributions to the Amateur Radio hobby. We thought that some of our readers here might enjoy the video. You can view it on our club’s home page here.
Several members of the Nashua Area Radio Club operated as N1FD/M (our club callsign) in the New England QSO Party this year as a Multi-Op Mobile Entry. Operators included Wayne Wagner, AG1A and Jamey Finchum, KC1ENX and myself. We began our operations on Saturday afternoon on the Massachusetts – New Hampshire State line where we activated two counties and two states.
N1FD/M NEQP Multi-Op Team
We entered the 2016 NEQP Contest in the High Power Multi-Op Mobile Category. We operated using SSB phone mode using mostly on the 20m and 40m bands. We took turns operating, driving and navigating. We used Fred’s, AB1OC’s mobile HF station in his truck.
CQ NEQP from N1FD/M
We operated Saturday and Sunday for nearly the entire contest period. We spent most of our time calling CQ and we had several nice pileups to work.
Counties Activated by N1FD/m in the 2016 NEQP
The map above shows the counties in Massachusetts, New Hampshire and Vermont that we activated during the contest. Anita, AB1QB helped us to create a route of counties to activate which included some of the more rare counties in Vermont and New Hampshire.
Operating on a County Line in Vermont
We tried to focus on activations where we could be in two counties as once. These activations produced some nice pileups for us to work.
Operating on a County Line in NH
We parked on county lines with 2 wheels of N1FD/M in one county and 2 wheels in another. This gave us two QSO points (one for each county) for each contact that we made.
NPOTA Activation – Marsh-Billings-Rockefeller NHP in Vermont
We had a few challenges along the way. We had some antenna related problems to deal with. Fortunately, we had spare parts with us and we adjusted our operating style to overcome these problems. We also had to operate through a major solar event on Sunday. This made contacts very difficult but we still logged over 235 QSOs on Sunday in spite of the conditions.
All in all, we had a great time in the contest. We logged a total of 631 QSOs and we worked 58 Multipliers. Our final claimed score was 36,598 – not bad given that this was our first entry as a mobile and our first time in NEQP. We worked 43 of 50 states and we had quite a few stations from Canada and Europe call in to answer our CQs. All in all, it was a lot of fun operating from our Mobile HF station in the NEQP contest!
There was some discussion on the way home about the Maine and New Hampshire QSO parties which will be held later this year. We hope to be N1FD/M again in one or more of those as well.
Our first day in Dayton was spent at Contest University – this was our 5th year in attendance but each year we learn more from the contesting experts. This year, we attended two presentations from Frank Donovan, W3LPL on operating techniques for the declining solar cycle and on 80m and 160m antennas. We also heard a talk from Val NV9L from Ham Nation on Log Analysis tools and another session on SO2R (Single Operator 2 Radio) Operating.
Slide from W3LPL Contest University Presentation
Friday was the first day of the Hamvention and we spent most of the day visiting all of the vendor exhibits. We visited the Icom booth, where we looked at the new Icom 7851. It has an incredible display as well as one of the best receivers on the market.
Icom IC-7851 Display on a Large Screen TV
We also saw the new KX2 Transceiver at the Elecraft booth. It is even smaller than the KX3 and is perfect for SOTA and other portable operations. I would expect to hear some NPOTA activations using this radio.
Elecraft Kx2 on Right, next to a KX3
Friday evening was the Top Band dinner where we learned all about “Top Band Disease” from Larry “Tree” Tyree N6TR. Hams with this disease are nocturnal, love the bottom of the sunspot cycle. They are constantly improving their 160m antennas – when you upgrade your receive antenna, then there are people who can’t hear you, so then you need to improve your transmit antenna – and the cycle continues…
Top Band Dinner Presentation by N6TR
After the dinner, we were treated to a concert from the Spurious Emissions Band (N0AX, KX9X, K4RO, W4PA), with hits like “On The Cover of the NCJ” and “Sittin on the Edge of the Band”. They were so funny! You can watch their performances on YouTube http://bit.ly/DaytonSpurs2016.
The Spurious Emissions Band Performs at Dayton 2016
On Saturday, Fred, AB1OC and I presented our Station Building talk to around 250 people as part of the Dayton Contest Forum. It was a great honor to be selected to speak there by Doug Grant K1DG, who has been organizing the Contest Forum for many years.
Fred, AB1OC Speaks at the Contest Forum
We also continued to tour the vendor booths, visiting our fellow Nashua Area Radio Club Member Bill Barber, NE1B, at the DMR-MARC booth.

After that, we stopped by Gordon West’s Ham Instructor booth where we spoke to him about the success of our Club’s License classes. Here is a picture of Gordon, WB6NOA and Fred sharing the secrets of how the Hilbert Transform and the Flux Capacitor make Single Sideband and Time Travel Possible.
Gordon West, WB6NOA with Fred, AB1OC
We also visited the AMSAT booth, where we met Burns Fisher, W2BFJ, who currently lives in Brookline, NH and is moving to Hollis. They had a cube sat on display – you can see how small it is below. It’s amazing that AMSAT builds and arranges to launch them into orbit so that we can make QSOs through them!
Anita, AB1QB Holds a Cube Sat
Fred could not resist a visit to Begali Keys where we purchased a neat travel key. It should be great for operating mobile and for Field Day.
Begali Travel Key
On Sunday, we headed back to New Hampshire, sad that the weekend had come to an end but full of great memories from the trip.
We entered the ARRL Rookie Roundup in the Multi-Op, Single Transmitter category using the club’s N1FD call sign. This gave everyone a chance to operate in the contest and to contribute to the team’s final score. Fred, AB1OC spent some time setting up and checking out our station ahead of time. Our operators used the N1MM+ logger and operated using 100w of power on the 20m and 40m bands.
We had a total of 13 Nashua Area Radio Club members who attended the preparation session and/or operated in the contest. Folks worked as teams during the contest with one person operating while another person logged. Our operators had nice pileups to work for a good portion of the contest. All of our Operators did really well.
As you can see from the video above, we definitely have some future contest stars in our club!
The table above shows the results of our operations during the 6 hour contest period. Our team did really well! Of particular note is that they were able to work 45 of the 70 available multipliers. It will take some time for the ARRL to put together the results for everyone in the contest but we believe that our team did very well.
Abby and her Dad Jamey Operating in the ARRL Rookie Roundup SSB
The results are in and N1FD took first place in the recent ARRL Rookie Roundup SSB in the Multi-op Category. The N1FD team was also #1 in area one and #5 overall in the contest. Congratulations to all of our operators – the did a great job operating in the contest. You can find all of the scores for the contest here.
