Inside a Secret 1940s WWII Agent Radio: The Lagercrantz Suitcase

In this video, we take a close look at a very rare piece of World War II history: a secret suitcase radio built in secrecy by Johan Lagercrantz in Stockholm during the war. This unmarked radio was used by the underground intelligence network. I will walk you through the unique wooden chassis, explain the transmitter and receiver schematic diagrams in simple terms, and show you the hidden battery compartment. Finally, we hook it up to laboratory power supplies and a dipole antenna to see if it still works. Watch until the end to hear an authentic over-the-air Morse code (CW) contact (QSO) on the 80-meter band! Thanks for watching! Please like, comment, and subscribe for more radio history. 73 de LA6NCA.
