Northern Radio

Navigational aids: Back to JP's Radio Homepage

Northern Radio had an interesting relationship to Technical Materiel Corp.  

It was a sister company, since its founder Salvatore Barone, worked as Chief Manufacturing Engineer for Ray de Pasquale (Director of Manufacturing) at Press Wireless during WWII.  As the war wound down, Press Wireless fell into financial difficulties and laid off most of its engineering staff, thereby creating several new companies (not unlike Silicon Valley today).  An examination of Northern's early products shows that their industrial design was very similar to TMC's, and also like TMC, Northern equipment was very well designed and beautifully made.

The company was a competitor as well.  In the early days of both companies, there were competing products, including the XFK (TMC) vs the Model 105 (Northern), and the VOX (TMC) vs the Model 115 (Northern).  The designs were similar, but not identical.

TMC also used Northern equipment as subsystems in their military systems, so Northern was a collaborator/supplier, in some cases.

A history of Northern Radio needs to be written..  Hint, hint!  I'm happy to collect information for this project, but I've been in touch with one of Sal's descendents, who's interested in doing this history, so for now, I'll pass it along to him!
