You have probably heard something about recent efforts to develop a special “FT8 DXpedition Mode” in WSJT-X. This message aims to bring you up-to-date on our progress, and generally to make our plans more widely known.
It looks like some of the major DXpeditions are beginning to embrace FT8. This will certainly create a need to handle “pileups” in FT8 mode and to make it possible to make many contacts in the shortest period of time possible. It appears that Joe Taylor, K1JT is working on an update to WSJT-X to create a variation of FT8 tailored for DXpedition use. Also, we will also need to update our copies of WXJT-X to take advantage of the new FT8 DXpedition mode. The link above is an article by Joe which gives more information about his new FT8 DXpedition mode and the software which will support it.
Bouvet Island is one of the most remote uninhabited islands in the world. It is 2700 miles east of South America, 1000 miles North of Antarctica and 1800 miles west of Africa. It is also the 2nd most wanted DX Entity just below P5, North Korea.

Bouvet Island DXpedition
A team of 20 Ham Radio Operators from all over the world is currently on a boat headed to Bouvet. They are headed there to operate for 2 weeks as 3Y0Z, so that the rest of us can get Bouvet Island in our logs. Their ship sailed for Punta Arenas, Chile on January 19th for the 10-12 day trip to Bouvet. You can watch their progress here,
Visit their website at http://www.bouvetdx.org/to see the latest news of their voyage and operation and learn more about Bouvet, where they plan to operate, who the team is, how to work them, check if you are in their log, and get a QSL. You can also follow them on Facebook by joining this group.
Is the 20-meter band open to the location of the latest DXpedition on the bands? When is 6 meters open for Sporadic E? Looking for a weak signal 2-meter contact with a specific grid square? There are websites you can visit that give you a prediction of whether the band you are on is open to a given destination.
HF Propagation
N0NBH Propagation Widget
The simplest HF propagation prediction is the widget that is seen on many Amateur Radio Websites – QRZ.com,DXSummit.fi, and more. This gives you a rough idea of what bands are open day and night. Data is based on the Sunspot Number, A and K indices, and other indices. But this doesn’t take into account many factors like your location, the DX location, the characteristics of your station, and the DX station. Just because 15m says Poordoesn’t mean you won’t hear anything on the band.
VOACAP – HF Propagation Prediction
VOACAP Point to Point Prediction
VOACAP is the Voice of America Coverage Analysis Program and provides detailed information about HF propagation. You can choose transmitter and receiver locations from many cities around the world. It also provides choices of Antennas, Power, Mode, and more for each end of the contact. You can look at several different views of propagation. If you spend some time delving into the details of propagation visit this site.
VOACAP prediction from DXSummit.fi
For a faster view of whether you will be able to contact a specific DX Station that is currently on the air, the DXSummit.fi spotting website has incorporated propagation predictions on their website. If you find a DX station spotted there that you contact, just right-click on the DX callsign and select VOACAP from the drop-down. You just need to choose whether you are a Basic (100 watts and a Wire) or a Superstation (Amplifier and Directional Antenna). You can also look at views of Short Path or Long Path. It will give you a good view of when you need to be on which band to contact the DX station.
6 Meters – The Magic Band
DXMaps – 6 Meter Openings
The best website that I have found for 6 meters is DXMaps.com. It provides a map view of the world or you can select a continent. Based on spotting network data, it shows 6-meter contacts and color codes them by Sporadic-E, Multihop ES, Meteor Scatter, etc… even Aurora. You can also get a view of 10 meters, 2 meters, or 70 cm. If you sign up for a free account, you can subscribe to real-time notifications when there is an opening near you.
2 Meter Propagation
VHF Propagation Map
Looking for a tropo opening for a weak signal 2-meter contact? Visit the website http://aprs.mountainlake.k12.mn.us/ to see a VHF Propagation map. This shows tropo openings as color-coded clouds – with brighter colors for the longer openings. This is based on APRS data.
These are the websites that I like to visit to understand the propagation forecast for the day. If your favorite site is not on the list, add a comment so the rest of our readers can check it out.
