Common digital mode Frequencies

[M0PWXParticipant]

One of the things I struggled with when i was starting to study and just after I passed my foundation was what frequencies do I find various digital modes on, or you hear a signal a bit like a fax / modem (if you remember these things) and want to know what it is likely to be so you can find the software to decode it

A useful place to look if you have a waterfall display either on your radio or software like WSJT-x or FLDigi is https://www.sigidwiki.com/wiki/Database . It has waterfall images and short sound clips of many identified and unidentified digital signals so can be a useful resource when trying to work out what a particular signal is, one you know the mode, you can then work out the software required to decode it

I built myself a table of frequencies for common amateur digital modes and the frequencies commonly used by them

PSKReporter is useful for many digital modes, as most common digital mode applications upload spots into it, goto PSK Reporter

my list is below, I hope you find it useful
