This site's goal is to present information to help digital amateur radio operators better understand and be able to more efficiently use the different Olivia digital mode configurations. This Olivia information page is NOW also including information for the Contestia digital mode which is derived from Olivia and has some advantages and disadvantages of it's own. The signal can be decoded even when it is db below the noise floor i. Currently the only other digital modes that match or exceed Olivia in sensitivity are some of the WSJT program modes that include JT65A which are certainly limited in usage and definitely NOT ragchew capable. It was developed at the end of by Pawel Jalocha. The tests proved that the protocol works well and can allow regular intercontinental radio contacts at very low power levels.

Are you interested in starting out with the amateur-radio digital modes on the high frequencies? Have you heard of FLDigi? For example, FLDigi allows you to operate using the Olivia digital mode.

Welcome to the Digital Station of NW7US - Tomas David Hood.
Post a Comment. Within the past week, I've been starting to use some of the digital modes on HF. I first tried PSK31 by successfully making a few contacts.
Olivia MFSK is an amateur radioteletype protocol, using multiple frequency-shift keying MFSK and designed to work in difficult low signal-to-noise ratio plus multipath propagation conditions on shortwave bands. The signal can be accurately received even if the surrounding noise is 10 dB stronger. The protocol was developed at the end of by Pawel Jalocha. The tests proved that the protocol works well and can allow regular intercontinental radio contacts with as little as one watt RF power. Since Olivia has become a standard for digital data transfer under white noise, fading and multipath , flutter polar path and auroral conditions.
