The Wilderness SST was designed around 1997 by Wayne Burdick, N6KR of Elecraft fame. It was kitted (by Wilderness Radio) and sold well to excellent reviews. On eHam the rig scores 5.0/5 from 33 reviews. It is an exercise in minimalist design, and there is obvious lineage to be seen in how certain aspects of the SST design found their way into the Wilderness range of QRP radios, such as the way the receiver is coupled to the PA output and monitors the transmitted signal, and the audio-derived AGC. It was respected among the QRP crowd in the USA (it appears in a list of QRP kits on Wikipedia, most of which are from US sources) but was not widely known here in VK. Fortunately, all of the resources and more to build this transceiver are easily found online.
