Enemy airborne radio equipment

The object of the paper is to describe the most widely used radio-communication installations and aids to navigation found in German military aircraft, with brief mention of Italian and Japanese practice. Since it is impossible in the space available to give full descriptions of the equipment, detailed attention is given only to points of particular technical interest. The items to be described perform roughly the same functions as their counterparts in British and American aircraft, but the practice with regard to methods of construction and installation is vastly different. The paper does not set out to compare German and British practice item by item, but it may be stated generally that, except in the case of fighter equipment, in which British practice is unquestionably superior, no outstanding advantage can be credited to either side. The equipment will be described under the following headings:- (1) Bomber general-purpose equipment, including intercommunication system and power supply. (2) Direction-finding and beam approach. (3) Fighter and single-engined dive-bomber equipment. (4) Pilots´ radio-telephone sets, or ¿command¿ sets. (5) Italian and Japanese equipment. (6) Installation practice; materials, construction and components.
