If you use WSJT-X there is a tab in the “Settings” menu item which lists the common frequencies for FT8, FT4, JT65, JT9 and all the WSJT modes.
But if you use FLDIGI, you instead have to find your own frequencies, and about 100 possible modes are listed. I found digital signals on HF, and wondered which mode that was. So I have made a chart of modes and frequencies logged on a Saturday afternoon, recorded to Ham Spots.
Wonder what mode it is? look at the frequency… maybe it’s in my list.
(This post will be modified as more frequencies and modes are captured)
