Motorola
In 1940 he started working for the Galvin Manufacturing Corporation in Chicago (the company changed the name in 1947 to Motorola). He is credited with three patents related to the design of Motorola's SCR-300 FM "Walkie-Talkie" radio, a hugely popular unit with American forces in Europe, and he received a U. S. Navy Certificate of Commendation for Outstanding Service for development of the AN/CPN-6 Radar Beacon, a microwave device which aided carrier pilots to find their ship during low visibility conditions.
After the war he did not return to the communist People's Republic of Poland and stayed in the USA. He helped in the development of VHF cavity resonators that allowed adjacent channel operation, was a key designer for the Motorola Sensicon receiver which used a selective filter in front of the IF amplifier, and created microwave relay equipment for use in transmitting multi-channel telephone, data and TV. In Motorola's Government Electronics Division he developed the SSB Radio Central Concept AN/USC-3, Motorola’s RADEM system (RADAS), the Deltaplex I digital troposcatter system and lightweight tropo equipment AN/TRC-105.
