[ARC5] Development of radio during WWI

[Leslie Smith]

The Germans were well aware of this, and for some time gained a good advantage by the interception of signals (morse).  When the Brits figured what the Germans were doing an officer (Fuller) developed a system to deal with the interception.  I have seen Fullerphones for sale on the web.
