Abstract :
A narrowband HF-SSB system designed to meet the requirements recommended by the Joint WMO/IOC group of experts on telecommunications for oceanographic data and command telemetry transmissions is described. The building blocks that compose this ocean data buoy HF telemetry system, and their more important characteristics, are listed. Narrowband versus wideband (standard SSB 3 kHz bandwidth) HF link tests conducted between San Diego and Portsmouth are discussed.
