During 1926 the United Kingdom imported $461,479 worth of radio apparatus from the United States, of which radio receiving set components accounted for $238,055 and receiving set accessories $125,212.

European radio magazines encourage home construction by giv- ing details, diagrams and other in- structions. While these sets, are not as efficient as those commercially manufactured, the large saving real- ized in homemade sets make them more in demand. Hearings Are Postponed.
