Abstract : Spatial Processing Group DSTOS currently has oblique ionosonde transmitters deployed in a variety of remote, often unmanned, locations in tropical, arid inland, and polar regions, and equipment reliability is of the utmost importance. The commercial H.F. power amplifiers initially installed proved unreliable in the field, and motivated the development of a more robust unit. 10 Watt and 50 Watt designs are presented with their measured characteristics, and a detailed discussion of important design criteria.
