I have been operating using the FT8 digital mode on the 6m band using our remote operating gateway quite a bit this summer. The SDR-based remote operating gateway in our station allows us to operate our station from other rooms in our home as well as from outside our QTH via the Internet. When I’m at home, I have computers set up with outboard monitors to create an operating setup for FT8 digital contacts on the 6m and other bands. The photo above shows this setup. Having the extra screen space and multiple laptops enables control of our station, making and logging QSOs, and checking propagation via Reverse Beacon Networks as we operate.
Flex-6700 SmartSDR and WSJT-X Weak Signal Digital Software
This laptop runs the WSJT-X software (left windows above) which conducts QSOs in FT8 and other weak signal modes and the JTAlert Software (lower right windows above) which interfaces WSJT-X to the DXLab logging suite. JTAlert displays all callsigns decoded by WSJT-X and compares them to my log to determine which potential contacts are new DXCC’s, Grids, States, etc. JTAlert adds contacts to my logs in DXLab when a QSO is completed using WSJT-X.
DXLab Suite Logging and Rotator Control Software
The windows laptop also runs the DXLab logging suite. DXLab handles logging of QSOs, the one-click pointing of our antennas based upon the callsign being worked, and uploading contacts to LoTW, eQSL, and ClubLog for confirming contacts.
Reverse Beacon Network and Station Monitoring Computer
I like to use the second computer to monitor the propagation and strength of my FT8 signal while operating.
PSKReporter RBN Monitoring on 6m
I use two tools to assess propagation conditions while I am operating. The first is PSKReporter which is a Reverse Beacon Network (RBN) tool that is enabled by WSJT-X and most other digital mode software programs. Each time WSJT-X decodes a station’s transmission, it reports the decoded callsign along with location and signal strength information to the PSKReporter website. This website then uses this information to display all of the stations that hear my and other’s transmissions in real-time. The RBN information is used to determine where a given band is open and as a tool to determine how much transmit power is needed to provide acceptable signal strength at stations that I am trying to work.
DXMaps Propagation Report on 6m
The DXMaps website shows a real-time map view of contacts being made on the 10m and higher bands. This second tool provides a real-time view of band conditions and opening on bands like 6m which have somewhat unpredictable propagation characteristics.
Together, these tools help to determine where to point antennas and what stations we can work on the 6m band.
The second laptop also runs Teamviewer remote control software. This provides access to the antenna switching controls, SWR and power monitoring equipment, station electrical power, and amplifier controls in our shack. These tools are important elements in safely operating and controlling our station when we are not in the same room as the radios and other equipment we are using.
Portable Satellite Station With Additions For Digital and Packet
We’ve recently upgraded our Portable Satellite Station 2.0 to add digital and packet capabilities. The upgrade was pretty simple – we added a SignaLink USB Soundcard and a Windows Laptop PC. Most of the software for packet and digital Amateur Radio communications is written for the Windows OS so using a separate laptop running Windows 10 was the simplest way to go. Another benefit of the second laptop was added screen space to use when doing packet communications via satellites and the International Space Station (ISS).
The video above was made during the reception of an SSTV image from the ISS during a pass over the United States. The video gives a good idea of what its like to receive SSTV from the space station.
Another SSTV Image From The ISS
We were able to receive several different images from the ISS during the period that it was transmitting SSTV worldwide.
A Third SSTV Image From The ISS
It was pretty easy to capture the SSTV transmissions from the ISS with our Portable Satellite Station 2.0 setup. The signals were strong and I would imagine that the SSTV transmission could have also been received with a simple portable satellite setup with a hand-held yagi antenna.
We hope that the ISS will send SSTV images again in the near future. It was fun receiving them.
I’ve been pretty active on the 6m band the past few years. As you can see from the image above, we’ve worked most of the grid squares in the eastern third of the United States on 6m. I use a mix of modes on 6m including SSB Phone, CW, JT65, FT8, and MSK144. The addition of the MSK144 mode for Meteor Scatter contacts has been a lot of fun and has added some new grid squares to my total.
Orionid Meteor Shower Forecast
One of the fall Meteor Showers, the Orionids, occurred not too long ago and I decided to focus on MSK144 during the Orionids to see how many grid squares I could work. The shower mast most active over a 3-day period (Friday, Saturday, and Sunday).
The video above shows an example of an MSK144 Meteor Scatter QSO using WSJT-X.
6m MSK144 QSOs During Orionids
So I bet you may be wondering how many 6m QSOs and grid squares was I able to work during the Orionids? I made a total of 23 Meteor Scatter QSOs using MSK144 during the 2017 Orionids. The image above shows the 16 grids that were worked using MSK144 during the three-day period. A few of these grids were new for me on 6m.
One of the best meteor showers of the fall, the Orionid Meteor Shower, will peak on Friday night with over a dozen meteors streaking across the night sky every hour.

It looks like this weekend is going to be a good time to work Meteor Scatter contacts on 6m! The Orionid’s peak tonight (Friday) and tomorrow (Saturday) night, October 20th and 21st. We’ll be operating using WSJT-X MSK144 mode on 6m. We are planning to use our Remote Operating setup to take advantage of our SDR’s receiver capabilities and the connected 500w amplifier.
The installation of the latest version of WSJT-X software to add current JT9, JT65, FT8, MSK144, and WSPR digital modes to our Remote Operating setup
These steps are now complete and we have some good results to share.
SmartSDR V2 Remote Connection
The first part of the upgrade was to update to SmartSDR V2. This upgrade enables much improved SmartSDR operation over the Internet. Our previous approach, which used a tunneled VPN connection combined with the previous versions of SmartSDR did not always perform well when used with low-bandwidth or high latency Internet connections. SmartSDR does much better in this area.
SmartSDR CAT Remote
Both the SmartSDR CAT and the SmartSDR DAX application have been updated to allow software on a PC being used to operate the FlexRadio SDRs over the Internet to gain access to CAT and sound interfaces associated with the radio.
FlexRadio Maestro Console
We also added a Maestro Console to enhance the usability of the SDR radio portion of our Remote Operating Gateway. The Maestro is very easy to use and extends the available controls and display space which was limited when using just a laptop PC. The Maestro supports direct microphone connections for phone operation and also works with connected CW paddles for operation in CW mode. I have been using a single level paddle along with our Maestro as speeds of 22 WPM with full QSK. Sending CW at these speeds with the Maestro works well.
The Maestro has built-in WiFi and Ethernet connections and full support for SmartSDR V2’s connections over the Internet. The Maestro can operate from AC power or from an internal battery pack. I have a couple of spare rechargeable batteries for our Maestro to support longer operating sessions on battery.
With the addition of the SmartSDR and the updated TeamViewer/VPN setup, we can operate our station remotely over the Internet. We have tested our setup using a Wireless Hotspot modem and Verizon’s LTE service. The combination of our PC running the DXLab Logging Suite and the Maestro work great in this configuration.
We have found the need to initialize the networking configuration in a specific order to get everything running correctly. The steps that we use are as follows:
Connect the laptop PC to the Internet
Bring up the TeamViewer VPN connection
Run SmartSDR on the laptop PC and login to SmartSDR Remote
Bring up the DXLab’s Suite including Commander (currently, DXLab’s Commander has some issues connecting when the FlexRadio protocol is used. We have found that the KENWOOD protocol works fine.)
Bring up the remote control application for the Elecraft amplifier and access our RigRunner power controller and microBit Webswitch units to turn on accessories as needed
Initiate a second TeamViewer Remote Control connection and use it to run the microHAM remote antenna controller in a single window
Shutdown SmartSDR on the laptop PC and bring up the connection to the radio via the Maestro.
There is obviously still some room for simplification in this initialization procedure. I expect that some simplification will come as all of the software involved becomes more mature and is further adapted for remote operation.
Once initialized properly, its simple to use the PC and Maestro combination to work SSB Phone or CW contacts. The DXLab Logging Suite will follow the radio, track modes, handle split operation, and allow control of our antenna rotators via DXView. We can click on spots in DXLab’s SpotCollector to automatically set the FlexRadio SDR’s mode, frequency, and split configuration. The Maestro and DXLab will stay in sync during tuning, mode changes, and other radio operations.
Remote Digital Operation using WSJT-X and FT8
The final part of this project was to add the latest Version of the WSJT-X software to our Remote Operating client laptop PC to enable FT8 operation on the HF bands and MSK144 for Meteor Scatter work on 6m.
These enhancements to our Remote Operating Gateway have helped both Anita and me to operate more. I have our Maestro either in my home office or on a table in our kitchen where we can listen to the bands and work DX when the opportunities come up. Remote Operating, even it’s just from another room at your QTH, is great fun!
The heart of any GoKit is the Transceiver. We’ve been using Kenwood equipment for our APRS iGate for some time now and we have had good results with it. Kenwood’s latest 50W transceiver with APRS is the TM-D710GA. This unit provides full support for APRS tactical applications and now includes a built-in GPS receiver making it ideal for our GoKit application.
We had a chance to look at the iPortable enclosure at Dayton and decided that their Pro 2 4U deep unit would be a good choice for our GoKit application. The iPortable enclosures are based on a portable rack mount case and include a DC power system, speaker and headphone hookups, a light, and provisions for a cooling fan.
With all the components in hand, we began the construction of our GoKit. Reliability is important in any portable system like this so we put some time into securely mounting all of the equipment and neatly arranging the cabling. First came the shelf which holds the Kenwood transceiver and a SignaLink USB sound card. A combination of drilling the shelf to secure gear with large cable ties and #8 stainless hardware was used here.
Coax Connector Cables
Our iPortable case was equipped with both SO-239 and N-connectors on the front panel to allow for antennas and feed lines equipped for either connector type. To make the change over between the connector types easy, we installed separate PL-259 jumper cables for each connector. One simply connects the appropriate jumper to the radio.
Display and Power Shelf
The power and AvMap display shelf was next. The AvMap display mount was dissembled and modified to accept a custom mounting bracket.
PWRgate Battery Interface and Charger
The iPortable enclosure was drilled to mount a West Mountain Radio PWRgate to handle backup battery charing and management. The PWRgate supports instantaneous switching between an AC power supply and a backup battery and can accommodate a wide range of battery types and sizes.
The last piece of the setup was the antenna. We wanted something that was portable, easy to set up and would provide good performance. We choose a Diamond X-30A 2m/70cm ground plane antenna and mounted it on an 12′ fiberglass push up mast. The feed line is made from 25′ of LMR-400UF coax. Several bungee cords are used to attach the mast to a fence post or other vertical structure.
The picture above shows the completed GoKit in operation. We typically set one side of the Kenwood TM-D710GA to operate as an APRS transceiver and Digipeater and the other side to operate on a local repeater or simplex FM. The SignaLink sound card is used with a laptop computer running Fldigi and NBEMS for messaging applications. The iPortable case has a 13.8V lighter socket which connects to a power brick to power our laptop PC.
GoKit Packaged for Transport
The GoKit is quite portable when closed. All of the equipment and cable connections are enclosed and protected by the case’s removable end caps. We’ve tested our GoKit during our club’s weekly repeater net and it worked great. The first real use of our new GoKit will be at Field Day this year. It will be located in our public information tent and will be used as a “talk-in” system.
WSJT-X developer Joe Taylor, K1JT, weighed in to express his appreciation to all who shared their ideas and experiences using JT9 and JT65 modes during recent multi-hop E-skip openings on 6 meters.
“We are very much aware that a mode with most of the excellent characteristics of JT65, but with faster turnaround time, would be a big winner in such situations,” Taylor commented on behalf of the WSJT-X development team. “We are experimenting with several such possibilities. Tentative goals include 15-second T/R sequences, sensitivity around S/N = –20 dB, occupied bandwidth less than that of JT65, and capability to decode as many as 10 or 20 signals in a 2-kHz bandwidth.”…
This is something to follow if you are interested in the JT modes for HF and VHF communications. Our experience is that a new JT variant that would trade S/N margin for a faster QSO segment speed would be just the ticket on many of the HF bands as well as 6m.
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.
I decided to become active on the 6m band this year. This 6m Sporadic E (Es) season was in full swing about a month ago when I got active on 6m. The picture above is from the DXMAPS website and shows one of the daily openings that we’ve experienced on 6m here in the US during the last month. The DXMAPS website is a good tool for monitoring for VHF/UHF band openings (10m and higher). The site collects and plots cluster spots and propagation mode information on a world map in real-time. This includes spots from CW Skimmers which monitor beacons on the VHF and UHF bands. This allows one to determine when a VHF/UHF band is open and the directions for possible QSOs from one’s location. As you can see from the picture above, there was a solid 6m opening on this particular day from my QTH in New England to the Midwest, the Southeast and the Caribbean! You can also see the beginnings of an opening into Europe.
Cluster Spots During A 6m Band Opening (DXLab SpotCollector)
The graphic above shows spotting cluster data (we use the DXLab Suite at our station). You can see the details of the stations being spotted during the opening.
Many of the 6m propagation modes can be very short-lived so one must be prepared to make short contacts at the start of a QSO. The typical 6m exchange would include callsigns, signal reports and grid square (more on grid square below). The 6m band is typically very quiet and will easily support QSOs that do not move one’s S Meter even with the rig’s preamps on!
SteppIR DB36 Antennas At Our QTH
We planned for 6m operation when we built our station a couple of years ago. Our primary antennas for 6m are our SteppIR DB36 yagis at 105′ and 65′. These antennas are used separately on the 6m band (we can run them as a 4 over 4 array on 10m – 40m).
SteppIR DB36 With The 6m Kit Installed Below Our 2m and 432 MHz Yagis
Out SteppIR DB36 Yagi’s feature, a 36-foot boom and have a 6m Passive element Kit installed which provide two additional elements on the 6m band. The resulting gain and front/back performance are in the range of typical 5 element 6m monoband antennas. Having two independently directional antennas for 6m has turned out to be quite useful in contests and when monitoring for 6m openings. These antennas have 6 elements on 6m and are pretty directional. Typical operating setups at our QTH would have one antenna pointed to the West or toward Europe while the other is pointed south to monitor for openings to the Southeast and the Caribbean. In these configurations, we can instantly switch between two directions using our microHAM Antenna Control System.
AB1OC Operating Position On 6m
Both of our two operating positions are 6m capable. They both feature Transceivers with good receivers (a Yaesu FTdx5000 and an Icom IC-7800) and both have PW-1 Amplifiers which provide 1KW output on the 6m band.
QSOs By Band As Of Early 2014
Before the 2014 Spring Es Season, we had only done limited operating on the 6m band. I did participate in the 2013 ARRL June VHF Contest and operated on a combination of the 6m, 2m and 70cm bands during that contest. I also did some 6m operating as part of the 13 Colonies Special Event in 2013. In total, I had made about 200 QSOs on 6m and had worked 10 grid squares by the beginning of 2014. Most of these 6m contacts were with stations in the US with a few to the Caribbean. My longest DX up to that point in time were a few contacts 6m stations in the Canary Islands on the northwest coast of Africa.
JT65 QSO using WSJT-X and JTAlert On 6m
At the start of the 2014 Spring Es Season, I decided to get serious about earning an ARRL VUCC Award on 6m. This award requires one to work and confirm 100 grid squares on the 6m band (it’s also available for 2m and higher bands). I began by studying 6m propagation modes and monitoring the calling frequencies on the 6m band. We work a combination of modes on 6m include SSB Phone, CW, and digital (using JT65). The CW and JT65 modes are very useful on the 6m band when the propagation conditions are marginal. We recently upgraded to Joe Taylor’s WSJT-X software which supports both the JT65 and JT9 weak signal modes. This WSJT-X software coupled with JTAlert software from HAMApps integrated the JT65 and JT9 modes very well with the DXLab suite that we use for logging and other DX’ing work at our station.
There were some exciting times on the air during the early part of the Es Season this year. Two that stand out were my first double hop Es contacts with hams in California and several openings to the Midwest and the Southeast where the band went from dead to very active in a period of 5-10 minutes! This is typical for the 6m band but it’s quite an experience to go from calling CQ with no answers to being in the middle of an almost instant small pileup!
AB1OC Claimed Score In 2014 ARRL VHF Contest
I also decided to operate in the 2014 ARRL June VHF Contest again this year. I decided to operate in the Single Operator, High-power Category on 6m only. I was able to make a little over 300 6m contacts in this contest and managed a score that was significantly better than my 3 band effort in this contest last year. My QSOs were primarily SSB phone mode but I also managed a number of contacts in CW mode and a few digital QSOs using JT65.
AB1OC Worked Grids In 2014 ARRL VHF Contest (N1MM Logger)
As you can see from the screenshot from the N1MM logger that I used for the contest, I was able to work quite a few grid squares. We had a very nice opening to the Southeast and Florida during the contest period and this resulted in lots of new 6m contacts and even some small pileups at times!
AB1OC Worked Grids In The Americas
By the end of the contest, my total grids worked was up to 98 and this put me very close to my goal of earning a VUCC on 6m. At this point, I was hooked on 6m!
AB1OC Worked Grids In Europe And Africa
A couple of days after the contest ended, I took a look at the DXMAPS website and saw that a good 6m opening was occurring into Europe. I got on the air and was able to make my first ever contacts into Europe on 6m. The opening was a “spotlight” one (covering a limited area) that involved double hop Es propagation in Spain, Portugal, France, and Morocco. Over the period of about an hour and a half, I made some 30 contacts into these countries. A very exciting time on the air and one that I will not soon forget!
AB1OC Worked Grids Around The World
With the opening to Europe and some continued operation on 6m I am currently at 122 Grid Squares worked (with 91 confirmed so far. My 6m QSO count stands at 755 with 112 new grid squares and approximately 550 QSOs made in the last 30 days.
The website used to plot the grid squares worked and confirm in the previous pictures is WG7J’s GridMapper site. Its a really nice tool to visualize the grid square one has worked or still needs to work.
At this point, I am totally hooked on the 6m band! While a yagi antenna with 5 or more elements helps a lot on 6m, I have found that it does not take a big station to have fun on the band when it’s open. I have worked many stations in the US who were using wire antennas and verticals with 100w or less. See the following YouTube video for an example of a simple 6m setup. Another good 6m intro video can be found here. If you have not given 6m a try, I encourage our readers to take a look at the band. It is really quite a lot of fun.
