On 27 February
27th,
1918 N.S.F. was founded by a number of ship owners.
They were interested in telecommunication equipment that could
be used for radio
transmissions between the mainland and ships at sea.
|
| In
July 1918 the factory started with Marconi licences. It was a
difficult start. An industry like this was completely new to
The Netherlands. There was no experience, the correct machines and tools
had to be made and the workers had to be educated. On October
12th,
1918 however, NSF celebrated the completion of the first
manufactured part: a transmitting coupler for the Dutch Navy. |

The first NSF
transmitter, that started on the 21st of July, 1923 was a public
broadcasting transmitter on 1075 meters (279Khz). The necessary
licence was issued for a transmission power of 20Kw. |

N.S.F. broadcast
transmitter building increased by the end of the 1920s. In this
area the cooperation between N.S.F. and
Philips
proved to be very lucrative. Here the experienced transmitter
builder and the big valve producer met. After the 500 Watt
experimental transmitter was completed in
1923, NSF constructed a newer version for 5
kW. In 1927 the building of the
1875 meter transmitter in Huizen started, commissioned by the Nederlandsche
Draadlooze Omroep. (Dutch Wireless Broadcasting) |
| In 1925
part of the
Philips
production line
was moved to N.S.F. in Hilversum, first battery rectifiers, later
- in 1927 - the first
Philips
receivers.
N.S.F. kept
on producing their own series of receivers every year, the
NSF4
and
the NSF5, together with the ultra-short tropical receiver I4A in
the years 1927-1928 were very successful. In the end NSF
receiver building blended in with
Philips'.
The brand name itself remained in use for some time. |
