Radio-Technisch Bureau "De
Tijdgeest" was founded in 1924 in Amsterdam. The address
was Egelantiersstraat
246-252. Managing director was J.G.N. Eweg, who had runned a
diamond-cutting factory at the same address since 1904. |
 |
In 1924, Eweg also owned "Het
Radio Huis" (later "Centraal Radio Huis"), Damrak 17, in
Amsterdam, a shop that sold radio's as well as binoculars, photo
and film cameras. |
|
In the period after it was founded,
the company tried to find sales representatives or agents for
the nationwide marketing of their receivers. "Radio
shops, Electro technicians,
Bicycle sellers and individuals with many relations",
were asked to respond. Gebr. Grit, Lage der A 9a in Groningen
responded and became the representative for the three northern
provinces: Groningen, Friesland and Drenthe. |
 |
In May 1925 the company first used
the brand name "Airvoice" in an advertisement. The
names Radio-Technisch
Bureau "De Tijdgeest" and "N.V. Airvoice
Radio" were both used in 1925. |
|
The
company was present at the International Radio Exhibition I.R.T.A.
in Amsterdam, in September 1925.
|
|
In January 1926 the company asked
for a deferred payment plan, and an administrator, Mr F.W.C.
Oldewelt, was appointed. |
|
On the 21st of February 1927 the
Military Hospital in Utrecht was presented with a radio
installation: a 5-valve Airvoice receiver, together with 3
loudspeakers and 35 head sets. Contributions by the military and
the general public made this possible. |
|
In an
advertisement in the newspaper Leeuwarder Courant of March 4th, 1927,
Airvoice tried to deny the rumours that there were problems with Airvoice: "A
recently announced auction may have implied that production of
AIRVOICE RECEIVERS has stopped. This is absolutely not true!! RADIO-AIRVOICE-RECEIVERS
are the best and will be produced by us as before.", it
says. |
|
The last
advertisements found are for model D02 at the end of 1927. |
|
In June 1928
the company asked for a renewal of the deferred payment plan. On
the 25th of June, the court agreed on a new period of one and a
half years, starting on July 11th. |
|
In the beginning of 1929, Airvoice radios were still
being produced, but later that year Eweg started
Multivox Radio. The Centraal Radio Huis went into
liquidation in 1931. |
