Spy radios of WWII

Just posted a video we shot of a talk given by Al Klase - N3FRQ at the Hall of Science Amateur Radio Club in Queens New York. The subject was military, and Spy radios through history. He had many examples of WWII hardware and how they evolved throughout the conflict. In a little while I will also post another video I made of all the equipment he brought. The table was laden with an amazing collection of equipment. Starting with some large early military sets and quickly getting very portable as the technology evolved. To the right you will see a picture of one of Mr. Klases own radios. A CMS , "painter's case" unit made for the US Navy around 1940, Mr. Klase in the video explains the circuit design and use. He also has some great shot of the famous suitcase-radio popular in so many of those WWII spy movies.
