This report focuses on transatlantic DX but may list other types of DX at the bottom. This other data is always for the full previous UTC day (i.e., decodes occurring before 0000 UTC on the day of the report). By contrast, transatlantic DX reports include data past sunrise, on the day of the report, for almost all of Europe. Other types of DX do not include Japan (which is separately reported by Hideo JH3XCU), but may include:

• North America / Oceania (occurs most days during several months)
• North America / South America (last seen 2021-04-15 0950)
• New Zealand / South America (last seen 2021-04-14 0952)
• Europe / east Africa (last seen 2021-01-28 0158)
• Australia / Europe (uncommon; seen in December 2019, for example)
• Australia / South America (historical status unknown)
• Australia / east Africa (historical status unknown)
