Ham Radio Modes

OK, let's start with the granddaddy of them all, Morse code. In today's parlance it's called CW or just "code". Yes it's still used today, and is still the "weapon of choice" for serious DXers and contesters. Other advantages are transmitters for this mode are easy to construct, CW gets through when band conditions are marginal or noisy and there is a standard system of abbreviations that work in whatever language is in use at either end of the QSO (that's one of those "standard codes").
