A 6m DX Opening to Remember

6m EU Opening - PSKReporter

6m Opening to Europe – PSKReporter Snapshot

Every now and then we get a really good opening to Europe on the 6m Band from here in New England, USA. This past Friday, June 4 2021 presented us with just such an opening. This particular one may well be the best one that I have ever seen. The opening began early in the day on Friday and was still going strong late into the afternoon. As you can see from the PSKReporter snapshot above, the band was solidly open to most of Western Europe and evening into the Middle East.

6m EU Opening - WSJT-X Snapshot

WSJT-X Snapshot During 6m Opening

There were so many strong signals from DX stations in Europe, it was difficult to decide which station to call next! I was able to work the opening for most of the day on Friday and was rewarded with over 130 DX contacts into Europe. In addition, I was able to Work 3 new DXCCs and over 40 new Grids (over 30 of these Grids have confirmed on LoTW already)!

6m EU Opening - JTAlert Snapshot

JTAlert Snapshot Helps To Work New Grids

We use the JTAlert application along with WSJT-X and DXLab Suite. JTAlert helped to identify stations in new Grids that we had not Worked before in the flood of activity on the 6m Band during this opening. At times, there were 4 or 5 different stations in new Grids being decode at once!

The 6m Es season has been very good so far this year with great propagation and lots of activity. Let hope that this continues well into the end of the summer here in New England. We are especially hoping for good 6m openings during Field Day later this month.

We’ve been wanting to try a Loop Fed Array (LFA) Yagi on the 6m Band. The Nashua Area Radio Society’s 2021 Field Day operation presented us with a good opportunity to do this. We choose a lightweight 3-Element LFA Yagi from InnoVAntennas and used a fiberglass mast to get it up 25 ft (about 8 meters).

The LFA Yagi performed very well! You can read more about this antenna’s performance and our upgraded portable station via the link above.

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.

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

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.

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!

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…

Field Day Satellites, VHF+ and Fox Hunting

We will have lots of great activities for folks who are interested in operating on the VHF and above bands at Field Day 2019. Here are some of the activities that we’ll be doing:

  • Satellites Contacts using a Portable Computer Controlled Satellite Stations
  • Weak Signal SSB, CW, and FT8 Contacts on 6m, 2m, and 70cm
  • Fox Hunting using Radio Direction Finding (RDF) to find hidden 2m Radio Transmitters
  • Satellite Station, VHF+ Station, and Fox Hunting Training

Source: Field Day Satellites, VHF, and Fox Hunting – Field Day 2019

The Nashua Area Radio Society always brings something new to each Field Day that we do. In addition to our Computer Controlled Satellite Station, we will be adding a state of the art Weak Signal Antenna System and Station to our Field Day 2019 lineup. Our VHF Station will use a dedicated 40 ft Tower with Tower Mounted Preamps and low-loss feedlines. You can see what is going on at Field Day 2019 on 6m and above via the preceding link.
