fldigi can operate on the following Olivia modes without special setup by the operator:
Unusual combinations of symbol rate and bandwidth can be selected using the Olivia configuration tab.
These are unconnected, simplex chat modes with full time Forward Error Correction. Olivia is a very robust mode with low error rates, but the penalty can be an annoyingly slow transfer of information. If you are a one finger typist then Olivia is your cup of tea. The tones are spaced the same as the baud rate, for example 31.25 Hz for the default baud rates. The default calling mode is 32-1000. It has the following appearance on fldigi's waterfall:
| Mode | Symbol Rate | Typing Speed | Bandwidth |
| Olivia 8-250 | 31.25 baud | 1.46 cps (14.6 wpm) | 250 Hz |
| Olivia 8-500 | 62.5 baud | 2.92 cps (29.2 wpm) | 500 Hz |
| Olivia 16-500 | 31.25 baud | 1.95 cps (19.5 wpm) | 500 Hz |
