Today, I made my first contact using the THOR digital mode, using fldigi, as shown here.
THOR is one of the digital modes used by amateur radio operators. The THOR mode is a family of offset incremental multi-frequency shift keyed modes with a low symbol rate.
The other station, Steve, KK4NNH, had a brief discussion about FT8, another popular digital mode, and format.
