OLIVIA

Our community is strong, and growing in number. We have participants in many countries. To foster the community's growth and education, we must connect with each other... Since Olivia signals can be decoded even when received signals are extremely weak, (i.e., signal to noise ratio of -14db), signals that are strong enough to be decoded are sometimes below the noise floor--below our ability to hear them, and not visible on the waterfall display--and therefore impossible to search for manually (by listening for the tones, or looking on the waterfall)... The protocol was developed at the end of 2003 by Pawel Jalocha. The first on-the-air tests were performed by two radio amateurs, Fred OH/DK4ZC and Les VK2DSG, on the Europe-Australia propagation path in the 20-meter shortwave radio amateur band. The tests proved that the Olivia protocol (or, digital mode) works well and can allow regular intercontinental radio contacts with as little as one-watt RF power (when propagation is highly-..
