Welcome to the Communication Equipment Forum. This is a place where information is exchanged about both wireless and wired communication equipment used by both the Allies and the Axis powers during the period between 1933 and 1945. Radar and airplane guidance equipment should also be covered on this forum. The collecting community of communication equipment has become quite large, and is growing constantly. This forum is a place where both novice and advanced collectors can gain valuable knowledge which will help them avoid the many pitfalls of this very interesting hobby.
German radio technology in the pre-war and war-time period was a full 20 years ahead of all other countries. Even though quality of materials deteriorated as the war came to a close, the design and and construction of these sets maintained its integrity. What was the key to the superiority of German radio technology of that time? CERAMICS. German engineers of the Hescho Porcellain Fabrik, developed ceramic substrates with stable dielectric properties patented as Calit / Calan. The Lorenz Company introduced magnezium-aluminum die-cast techniques for chassis construction, which considerably improved the specifications of their new products. Hans Vogt invented low-loss iron dust-core materials. Construction became modular and sectional. The standard 19 inch rack was invented and used for the first time. The Köln E52 series of receivers were constructed with modules that plugged into a "motherboard". These and other amazing inventions were created by Germany during this period.
