Olivia is a high duty cycle transmission mode which enhances the popular multi-shift frequency keying (MFSK) technique, providing an additional layer of forward error correction. It is this additional layer of error correction that allows Olivia to be a high signal-to-noise ratio champion.
Powered by a Raspberry Pi mini computer, the KD2NSP 20-meter WSPR beacon is now active and making 100mW transmissions every 10 minutes.
Solar minimums don't have to be grim. Bring some life to the ionosphere with WSPR.
