One of the first commercially built portable type receivers. using a crystal detector and a simple type of tuning unit, the set was not very sensitive. good reception was possible only in the vicinity of the higher-powered stations, and then only when a fairly long antenna was used which likewise restricted its use as a "portable" set.
