I'm both a history buff as a radio buff. In the World War II forums there are threads ad nauseam about the best fighters/tanks/bombers. I am interested in which of the combatants had the best radio technology and equipment. As a teen in the 60s in the Civil Air Patrol I operated for a week a Navy TCS-14 (photo at right) with a home-brew power supply. One of the neighbors had a FM radio from a tank with push button channel selection and crystals (he had a full set), but we had no one to talk to (and no license).
