We will be hosting a Tech Night about Building and Operating a VHF+ Weak-Signal Station tonight, July 14th at 7 pm Eastern Time. The live, interactive video of our tech Night will be shared via a Zoom conference and all of our readers are welcome to join. I plan to cover the following topics during our session this evening:

  • Why do weak-signal work on 6 meters and above?
  • What can you work and what modes are used on these bands
  • How does propagation work at 50 Mhz and above and how can you measure it?
  • How does one operate using SSB, CW, and digital modes on these bands?
  • What equipment is needed and what are some possible ways that you can put together a VHF+ station?
  • Some demonstration of actual contacts

In addition to an overview of how to get on all of the bands above 50 MHz, we will focus on the 6 Meter (Magic) band. The session will include demonstrations of FT8 and Meteor Scatter contacts on 6 m. I will also briefly describe the 6 m station here at AB1OC-AB1QB and show how we use it to make contacts. A second Tech Night will cover stations and weak-signal operating on 2 m and above.

The Zoom information for our Tech Night Session follows. We suggest that you join early so that you have a chance to make sure that your computer, speakers, microphone, and camera are working.

July 14th, 7 pm Eastern – Nashua Area Radio Society Tech Night. Fred, AB1OC Setting up a VHF+ Station. Here’s an opportunity to learn how to add 6 m and above weak-signal modes to your station. Join Our Zoom Meeting

We hope to see many of our readers this evening!

13 Colonies Special Event QSL Card for K2K, New Hampshire

13 Colonies Special Event QSL Card for K2K, New Hampshire

The 2020 Thirteen Colonies Special Event is in the books as I write this. The K2K New Hampshire Colony had a record year in 2020 for our state.

World Class Stations and Operators

Matt Strelow, KC1XX joined the K2K team this year. Matt’s superstation and he and his team of world-class operators enabled us to break some records in 2020. Our 2020 operator team included:

  • AB1BY – Abby, Operating from AB1OC, Hollis, NH
  • AB1OC – Fred, Hollis, NH (State & QSL Manager)
  • AB1QB – Anita, Hollis, NH
  • AC1DC – Jamey, Nashua, NH
  • K1DLM – Dave, Operating from AB1OC, Hollis, NH
  • K1GQ – Bill, Wolfeboro, NH
  • K1QX – Craig, Operating from KC1XX, Mason, NH
  • KC1IMK – Keith, Candia, NH
  • KC1IML – Mark, Candia, NH
  • KC1XX – Matt, Mason, NH
  • KM3T – Dave, Operating from KC1XX, Mason, NH

  • NN1C – Marty, Operating from KC1XX, Mason, NH
  • W1FV – John, Operating from KC1XX, Mason, NH
  • W3UA – Gene, Bedford, NH
  • WA1Z – Bob, Operating from KC1XX, Mason, NH

All of the members of the 2020 K2K operating team are also members of the Nashua Area Radio Society.

A Record Year for K2K

Final Contact Breakdown for K2K 2020

Final Contact Breakdown for K2K 2020

The K2K Team made an amazing 22,696 contacts during the July 1 – July 7, 2020, Thirteen Colonies period! This shattered the previous event record for a single state of 16,092 contacts. We are hoping that this will be an event record when the final 2020 results are in. Equally amazing was the fact that over half of the K2K operators made over 1,000 contacts including some ops with relatively modest home stations.

Operations Breakdown – Bands, Modes, and DX

Contact Breakdown by Day and Mode

The team managed a fairly even split between voice (SSB) and CW contacts thanks, in large part, to the operators at KC1XX. A good portion of the 2020 K2K contacts also came from digital operations (4,528 QSOs via FT8/FT4) which made up 20% of the Contact total.

Contact Breakdown by Day and Band

Contact Breakdown by Day of the Event and Band (click to enlarge)

The 20m band was the most productive this year but we made contacts on all of the available bands from 160m up through 70cm. The 40m band was also a strong contributor. We had some amazing performance on the higher bands with:

  • 60 contacts on 12m
  • 410+ contacts on 10m
  • 125+ contacts on 6m

This was the result of some solid Es openings during the event.

K2K QSOs Around The World

We set out to increase our focus on DX contacts this year and our approach resulted in some good results. We achieved great contact coverage in Europe and Japan as well as many contacts all over the world.

The 2020 K2K Team achieved a Triple-Play of Working All States in SSB, CW, and Digital modes and our team worked a DXCC with a total of 119 DXCC entities in our logs. Several operators on the K2K team focused on Japan and we worked a total of 168 JA contacts!

Some of our longest and most interesting contacts include:

  • BA5AD in China
  • E20WXA in Thailand
  • EX8TR in Kyrgystan
  • HL3GOG and others in South Korea
  • VU2USA and others in India (5 contacts total)
  • YC7YGR and YB2TS in Indonesia
  • Many ZS’s in South Africa
  • Many UA0’s in Asiatic Russia

Anita, AB1QB, and I operated our station here in Hollis, NH during the entire 2020 Thirteen Colonies period. The highlight of Anita’s operation was a tremendous pileup and run of DX in Europe on Tuesday evening. Anita also ran our digital station during the event.

AB1OC Operating as K2K

I spent most of my time during 2020 Thirteen Colonies doing a mix of SSB and Digital. We had two transmitters on the air at our station and I was able to operate both simultaneously (one SSB and one Digital) when the pileups were not too big.

Digital Station Dashboard

We used the N1MM+ Logger and other software during our 2020 operation here at AB1OC-AB1QB. An example of the digital station operating dashboard is shown above. We made extensive use of our Flex SDR platform and network computing environment here at our station as part of our K2K operations. You can learn more about the station here on our blog.

AB1BY Operating as K2K

Several younger members of our Club operated our station remotely during the 2020 Thirteen Colonies period. Abby, AB1BY did some live streaming to during her operating times and we captured the image above during one of her live streams. Keith, KC1IMK also operated our station. We have been encouraging our younger members to operate in Thirteen Colonies to develop their skills as operators.

Jamey, AC1DC's Station

Jamey, AC1DC’s Station

The story behind K2K’s success this year is all about our operators who used their home stations to contribute a good portion of our final contacts. It’s much more difficult to manage pileups and make many contacts from a smaller station with wire antennas and limited power. I want to especially thank our operators who put in the hard work from their home stations to help us make contacts – thank you!

QSL!

So Close – A 6m Opening to Japan from New England

A Recent 6m Band Opening Between Japan and the United States (PSK Reporter)

We’ve been having a good 6m Es Season in the Eastern United States this year. One thing that all of us here in New England look for is a chance to work DX contacts on the 6m Band. We’ve been fortunate to have almost daily openings from our region to Europe, Central, and South America. One 6m DX activity that is very rare is the ability to work stations in Japan via the 6m band from stations here in New England.

Recently, we saw one of the best openings between the United States and Japan that we have encountered here in New England. The image above shows contacts being made on the 6m Band via the FT8 Digital Mode between Japan and the United States on June 18th, 2020 in the evening eastern time.

So Close – Japan Opening to New England on 6m (PSK Reporter)

The pattern of 6m Es openings between Japan and the United States, not surprisingly, typically begins with West Coast and Midwest Stations and works eastward. We’ve been seeing these openings progress to include stations in the Southeastern United States recently on a regular basis. We monitor PSK Reporter and we use our station in receive-only mode to monitor the progress of 6m openings to Japan when they occur.

As you can see from the image above, the 6m Japan opening on June 18th progressed tantalizingly close to our QTH here in New Hampshire. This is one of the best openings to Japan into the Northeast region that we have seen to date.

Unfortunately, this particular 6m opening did not quite make it to our location here in New Hampshire. Perhaps we will see another, better opening before the end of this Es Season.

6m VUCC In A Day – ARRL June VHF Contest

6M VUCC Operating Award

6M VUCC Operating Award

The 6m Band is one of my favorite bands. The combination of its unpredictability and the amazing openings that it can produce certainly makes 6m The Magic Band for me!

Fred’s (AB1QB) First Place Finish in NH – 2013 ARRL June VHF Contest

Fred’s New Hampshire First Place Finish in the ARRL June VHF Contest

I haven’t had the chance to work the ARRL June VHF Contest from our home station for several years. A combination of Nashua Area Radio Society activities and preparations for ARRL Field Day have taken a higher priority. ARRL June VHF is a great contest and I was looking forward to working it this year. A few days before the contest Anita and I were talking about the contest and she suggested that I do a 6m Digital Entry. E-skip has been pretty good on 6m this year and we wanted to sort out how we’d do digital and 6m for our upcoming 2020 Field Day Operation from our home so I decided to take Anita’s advice and focus on 6m Digital for June VHF. I entered the contest in the Low-Power Category.

June VHF Operating Setup

6m VUCC

AB1OC Operating in 2020 June VHF

We built a Remote Operating Gateway that allows our station to be operated both over the Internet and from any room in our home via our Home Network. I decided to set up a 6m Digital Station upstairs in our dining room so I could be with Anita more during the contest. The setup consisted of a laptop PC with an outboard monitor and a Flex Maestro as the client for the Flex 6700 SDR in our shack.

Completed Antenna Stack On New Tower

Completed Antenna Stack on our VHF Tower

We have three antennas for 6m – one on our VHF Tower and two via the SteppIR DB36 yagis with 6m kits on our main tower.

Delta Loop On Tower

SteppIR DB36 Yagis on our Main Tower

The three antennas can be pointed in different directions and selected instantly via the computer. This provided to be an advantage during the contest. I kept one on Europe, one point due West, and the third pointed at the Tip of Florida and the Caribean during the contest.

6m VUCC

Operating Setup – N1MM+ and WSJT-X

Having two monitors (the Laptop and an outboard one) allow me to arrange all of the N1MM+ Logger and WSJT-X windows for efficient operating. The image above shows a snapshot of the screen layout during the contest. N1MM+ has some nice features that integrated with WSJT-X to make it easy to spot new grids (Multipliers) and stations that have not yet been worked. The windows on the very right side allowed me to control antenna switching and monitor power and SWR while operating. I use the PSTRotator application (lower-left center to turn my antennas.

6m Band Conditions

6m VUCC

6m PSK Reporter On Sunday Evening

Band conditions on 6m were amazing from here in New England almost the entire contest period! The band was open right at the start of the contest on Saturday and remained open to 11 pm local time on Saturday evening. I was up early on Sunday and was working folks in the Northeastern Region right from the start. After being open all day on Sunday, the band shut down around 5 pm local time and I was afraid that the fun on 6m might be over. I ate some dinner and took a 45-minute nap and got back to my station at around 6:30 pm. About 15 minutes after I resumed, 6m opened again to most of the United States and I was able to work DM and DN grid squares in the Western States! The band stayed open right until the end of the contest at 11 pm local time.

What About the VUCC…

6m VUCC

100 Grids Worked on 6m

Conditions on 6m were so good on Saturday that I almost worked a 6m VUCC by 11 pm on Saturday evening when the band closed. I had 93 grids worked on 6m in just 8 hours! The band opened again early on Sunday morning and I worked my 100th grid square before 10 am – working a 6m VUCC in less than 18 hours!

6m VUCC

Final 6m Grids Worked

By the end of the contest, I had worked a total of 162 Grids! They ranged from the West Coast of the US to Western Europe and from Southern Canada to Northern South America.

The image above shows most of the 6m grids that I worked plotted on a world map (the EU grids are not shown).

6m VUCC

Final Claimed Score

I was able to make a total of 402 unique contacts on 6m by the end of the contest with a final Claimed Score that was a bit over 65K. All of my 6m contacts during the contest were made using a combination of FT8 and FT4 modes on 6m.

New Ones on 6m for AB1OC

AB1OC Worldwide 6m Grid Map

I was hoping to work some all-time new Grids and June VHF did not disappoint. I worked a total of 11 new Grids and one new DXCC (Dominica) on 6m during the contest. The image above shows my worldwide grid coverage including the new ones worked during June VHF (my grids in Argentina and Uruguay are not shown above). I now have worked 432 grids on 6m and have confirmed 408 of them with 63 DXCC’s worked and 62 confirmed on the Magic Band.

Summing It All Up…

I must say that I had as much fun working 6m during June VHF this year as I have ever had in any contest! The band openings on 6m were really good and I was busy making new contacts for the entire time that I operated. The combination of the 6m Band and the contest certainly made some Magic for me!

AO-27 Is Back!

AO-27 Satellite

AO-27 Satellite

The AO-27 FM satellite is back on the air! AO-27 is an FM V/U Mode satellite that was launched back in 1993. The satellite’s Amateur Radio payload became inoperative about 7 years ago due to an internal communications failure. Thanks to some great work by Micheal, N3UC who was one of AO-27’s original designers, the satellite is back on the air on a limited-time basis (4 minutes, twice per orbit over the mid-latitudes).

I was able to make my first contact through AO-27 this morning. The contact was with AI9IN in Indiana, USA. I’m looking forward to making more contacts using this satellite in the near future. Here are the current frequencies for the uplink and downlink (no PL tone is required):

  • Uplink – 145.850 MHz FM
  • Downlink – 436.7975 MHz FM

It’s great to have yet another FM satellite that we can all use. I hope that other satellite operators will give AO-27 a try.

Getting Started With Amateur Satellites (and Progressing to Linear Birds)

Get Started with Amateur Satellites

Get Started with Amateur Satellites

We get quite a few requests from folks to explain how to get started with Amateur Radio Satellites. Requests for information on how to build a computer-controlled ground station for Linear Satellites are also pretty common. I recently got such a request from our CWA class so I decided to put together a session on this topic.

We covered a number of topics and demonstrations during the session including:

  • How to put together a simple station and work FM EasySats with HTs and a handheld antenna
  • A recorded demonstration of some contacts using FM EasySats
  • How-to build a computer-controlled station and work Linear Transponder Satellites
  • Fixed and Portable Satellite Station Antenna options
  • A recorded demonstration of some contacts using Linear Satellites
  • How-to work digital (APRS digipeater) contacts
  • How-to receive SSTV Transmissions from the ISS

About 30 folks attended this session and there was some good Q&A throughout.

Getting Started With Amateur Satellites

The presentation was recorded and can be viewed above. Here’s a link to the associated Powerpoint Presentation.

There are lots of articles about building and operating Amateur Satellite Stations here on our blog. The following are links to several articles and series on this topic:

I hope that you find this information useful for your Amateur Satellite projects!

Perspectives on a 6m DX Opening

6m DX Opening to Europe - PSK Reporter

6m DX Opening to Europe – PSKReporter

I’ve had a chance to operate on the 6m Band this past week. We are approaching the prime time for the summer Es (E-Skip) season here in the Northeastern United States. As a result, I wanted to see how propagation on the 6m band might be unfolding during this spring Es season. I was fortunate to catch a typical limited DX opening on the 6m band between our location here in New England and Europe. I thought that it might be helpful for those who are relatively new to the 6m band to see what this was like.

DX Opening Begins - JTDX Software View

A 6m DX Band Opening Begins – JTDX Software View

I spent some time on and off yesterday calling CQ and monitoring the 6m band using the JTDX software and FT8 mode. FT8 now dominates most of the activity on the 6m band. This is a result of a combination of FT8’s weak-signal performance and available reverse beacon tools such as PSKReporter. As you can see from the JTDX screenshot above, the 6m band was basically only open to the United States here until about 16:58z. At that point, I weakly decoded CT1ILT. This station faded almost immediately and I was unable to make a contact.

Approximately 4 minutes later, the 6m band opened solidly to Spain and France and quite a few stations in this area of Europe appeared with relatively strong signals.

6m DX Opening to Europe - Spotlight Area Propagation

6m DX Opening to Europe – Spotlight Area Propagation (PSKReporter)

As you can see from the PSKReporter screenshot above (taken near the end of the band opening), the probation on 6m was quite strong but limited to a very specific area and heading in Europe. This is typical of limited double-hop Es propagation. We most likely had two Es clouds aligning in such a way that a narrow path of propagation had been created on the 6m band.

A 6m DX Band Opening In Full Swing - JTDX Software View

A 6m DX Band Opening In Full Swing – JTDX Software View

The view above shows the 6m band opening in full-swing. I was hearing 5-6 strong stations from France, Spain, and Italy almost immediately. These stations are all on a relatively narrow range of headings center at about 65 degrees from my QTH. I am scrambling to work the stations that represented new grid squares for me. I am using JTAlert as a bridge to my logger (DXLab Suite) and it is telling me that 2-3 of the station in the mix are in grid square that I have not yet worked on the 6m band.

A 6m DX Band Opening Comes to an End - JTDX Software View

A 6m DX Band Opening Comes to an End – JTDX Software View

Like all good things, the 6m DX opening had to come to an end. As you can see above, the 6m band closed as rapidly as it opened, leaving me calling CQ with no takers to work in Europe.

Contacts Made During the 6m DX Opening

Contacts Made During the 6m DX Opening

The total duration of this opening was about 20 minutes. The contacts that I made during this period are shown above. During the brief opening, I was able to make a total of 11 contacts with a limited set of grid squares in Europe. Most of the signals were quite strong (see the Sent and Rcvd columns in my log above). During the opening, I worked 5 new grid squares that were centered around the border between France and Spain.

AB1OC 6m Grids Worked and Confirmed

AB1OC 6m Grids Worked and Confirmed

By this morning, three of the five new grids that I worked had already confirmed on LoTW. Just for fun, I plotted my 6m grid progress on the Gridmapper website. I keep a copy of the Gridmapper view of my log by my operating area as a reference that I use in conjunction with PSK Reporter to help me identify 6m band openings that might provide opportunities to work new grids.

I hope that this article gives you some idea of the nature of 6m DX openings. The opening described here is pretty typical in that:

  • The band open (and closed) suddenly without much warning
  • The propagation was very good with many strong signals being decoded and worked at once
  • The opening was of short duration lasting only about 20 minutes
  • The band closed as rapidly as it opened
Monitoring the 6m Band at AB1OC

Monitoring the 6m Band at AB1OC

In order to work 6m DX, this experience emphasizes the need to monitor the 6m band for DX openings on a regular basis. This is most easily done using PSKReporter. The pattern of DX openings on 6m to Europe from here in New England is such that EU DX openings typically begin south of us and progress northward. I use our Remote Operating Gateway, a Flex-6700 SDR based setup, to monitor the 6m band for DX openings while I work here in my office. You can see the 6m FT8 setup here in my office running in the monitor-mode above.

FlexRadio Maestro Console

I use the Maestro here in my office as my SDR client.

I hope that this information has been useful to our readers. As you can see from this example, the 6m Band is called the Magic Band for good reason. It is very exciting to be able to catch and work a good DX opening on 6m. The FT8 mode has both increased the level of activity on the 6m band and made 6m available to many stations with simple antennas and 100W transceivers. You can learn more about how to get started with FT8 on 6m here.

As I sit here writing this, the 6m band just opened to Austria and Hungry! Have to go work some DX on the 6m band…
