Will RADE Be the Next SSB?

Every so often a mode comes along that genuinely threatens to reshape how we talk on HF. Fifty years ago, that mode was single sideband, which overtook AM as the dominant voice mode largely because it packed a signal into roughly half the bandwidth. Now there's a new contender aiming to do the same thing all over again.

FreeDV has introduced a new digital voice mode called RADE — short for Radio Autoencoder — which occupies half the bandwidth of an SSB signal, while reportedly delivering more natural-sounding speech than earlier digital voice modes have managed.

UN Agencies Warn: Spectrum Interference Is Putting Early Warning Systems and Climate Science at Risk

Spectrum congestion isn't just an amateur radio problem — it's now a public safety one, according to two of the United Nations' leading technical agencies.

The International Telecommunication Union (ITU) and the World Meteorological Organisation (WMO) have called on governments to introduce tougher protections against radio spectrum interference, warning that the same frequencies used to monitor climate, forecast weather, and deliver early warning messages are increasingly being crowded out by satellite and wireless systems.
