Where do I go to find DX on FT8?
The most common DX stations typically use the standard FT8 frequencies.

If it is a DXpedition, the frequencies are typically posted on their website. You can also look at pskreporter for the frequency if they have transmitted recently. https://pskreporter.info/pskmap.html

I see the DX station sending nonstandard messages. Why?
Lots of DX stations use a special program called MHSV to transmit. You don’t need to use this special program; WSJT-X will decode the messages as normal. You can double-click on their message, and it will transmit normally.
