Short Description OLIVIA is an amateur digital teletype mode designed by Pawel Jalocha SP9VRC in 2005. It's goal was to be effective even in poor propagation conditions.
I/Q Raw Recording
Audio Sample
OLIVIA is an amateur digital teletype mode designed by Pawel Jalocha SP9VRC in 2005. It's goal was to be effective even in poor propagation conditions. It can also decode well under other noise, QSB, QRM, flutter caused by polar path propagation and even auroral conditions. Olivia uses 7-bit ASCII alphabet. There were a handful of amateur digital modes that were derived from Olivia, including RTTYM and PAX.

This mode is utilized during the tests run by the VoA every weekend. See the VoA RadioGram website for the schedule.


Olivia Submodes[edit]

125, 250, 500, 1000, and 2000 are the available bandwidths. 4, 8, 16, 32, 64, 128, and 256 are the available tones. There are a total of 40 possible submodes.

Olivia's submodes are determined by bandwidth and number of tones. This is represented with the "OLIVIA X/Y" or "OLIVIA X-Y" format, where X = # of tones and Y = Bandwidth in HzHertz (Hz), unit of frequency, defined as one cycle per second (1 Hz).. E.g: OLIVIA 8-250 means 8 tones with 250 HzHertz (Hz), unit of frequency, defined as one cycle per second (1 Hz). bandwidth.

The standard Olivia submodes (tone/bandwidth) are 4/125, 8/250, 16/500, 32/1000, and 64/2000.

The most commonly used submodes in order of use are 16/500, 8/500, 32/1000, 8/250, and 16/1000. Most Olivia usage is using one of the 7 following submodes: 32/1000, 16/1000, 16/500, 8/500, 8/250, 4/250, and 4/125.
