Grimm und einer Handvoll ehemaliger Mitarbeiter von Vitro Electronics gegründet und produzierte mit dem 901 einen verbesserten Nachfolger des 1906 von Nems-Clarke. Die Produktion wurde in den Zeiten des Kalten Kriegs rasch erhöht, bis es 1967 zur Übernahme durch an der Westküste im ähnlichen Segment tätige Watkins-Johnson Comp. kam.

| History: |
A number of former Vitro Electronics employees around Ralph E. Grimm founded Communications Electronics Inc. 1960. They started production of the 901 surveillance receiver in a quite small production plant in 4908 Hampden Lane, Bethesda, MD. In 1964 they had to move to a bigger production plant located at 6006 Executive Boulevard, Rockville, MD. Three years later, CEI had to expand it's production facilities again. That was when the company has been taken over by Wakins Johnson Comp., originally based in Palo Alto, CA. From 1969, the former CEI sets carried the WJ logo on their front panel. Another new production plant has been contructed and the CEI branch of Watkins Johnson moved to 700 Quince Orchard Road, Gaithersburg, MD.
