Trans Oceanic Royal D7000
überarbeitet am 3.11.2010
In 1969, Zenith brought out the Royal D7000, this travel receiver had not only FM band coverage but also a BFO to receive CW and single sideband transmissions.
The Royal 7000D is the last model of the solid state "Trans Oceanic" receivers
it is equipped with a FM tuner and covers also the U.S. waether band around
160 MHz in the VHF band. The size of the receiver is 35 x 26 x 15,7 cm and it's weight 2 kg.
The Royal 700D comes with a rugged carrying handle, in contrast to the earlier models, the telescopic antenna can be pulled at the back of the top face, behind the world time converter.
In the upper part of the front panel, You find the frequency dials, the Trans Oceanic Royal 7000D
has a turret tuner arrangement operated from a band switch at the right small face
of the receiver, a similar arrangement is found with Sony's CRF-5090 "Earth Orbiter"
or the Braun T1000.
The receiver has a similar sensitivity as found in Grundig Satellit receivers made in the same years, there is only one AM bandwidth, the dial calibration is acceptable only in the 31 - 16 meter bands, bandspread in the 49 m band important in Europe is not available. The value of the BFO and manual gain control is reduced through the fact, that there is no bandspread dial for the popular 80 and 40 m amateur bands, they are all found in one single very crowded 4 - 9 MHz frequency range.
Summary: The Zenith Trans Oceanic Royal 7000D is a nice collector's item
and can still be used as a simple travel radio, as long as You have no high
expectations from it's performance on shortwaves, it performs well on mediumwaves
and in the FM band to listen to Your favourite local stations. There are
some improvements in comparison to older radios with the BFO, two bandwidth
filters and manual R.F. gain control, but You cannot make much use of these
features as the receiver's bandspread is poor in many important shortwave
broadcast and amateur radio bands.
