In den Fünfzigerjahren brachte Collins mit den 75A, 51J - Empfängern und den etwas kleinformatigeren Geräten der "S-Line", 75S und 51S, technisch und mechanisch hervorragende Geräte heraus, welche bzgl. techn. Leistungen wie auch Design Meilensteine waren.
1973 wurde die Firma von Rockwell übernommen und wendete sich als Rockwell - Collins Inc. militärischer Übermittlung und der Avionik zu.

The 75A ham band receiver presented in 1946 with it's crystal controlled first oscillator and permeability tuned second oscillator was considered as an all-time classic amateur receiver.
