Belmar Receiving Station

The Belmar receiving station operated with the high power transmitting station in New Brunswick, NJ.  The station was seized by the US Navy during WWI and provided a primary link between the US and Europe using the call NFF. 

The Belmar station was located at what is now Camp Evans.  The original buildings were constructed between 1912 and 1914 for the American Marconi Company by the firm of J.G. White which also built may of the other Marconi stations around the world. 

Edwin Armstrong and David Sarnoff listened to Armstrong's revolutionary regenerative receiver at Belmar on the night of January 31/February 1, 1914.

Like most Marconi stations for the time, Belmar had residences for station staff, including a hotel.

Fantastic photo of a group tour of the New Brunswick transmitting station conducted by David Sarnoff.  Among the notables present are Steinmetz and Einstein.  The latter seems to be carefully eyeing Sarnoff who reportedly toppled over just after the photo was taken.
