Trans Oceanic H500
überarbeitet am 3.11.2010
Ten years after Zenith had their earliest "Trans Oceanic" on the shelves,
the multi band superhet H500 equipped with miniature tubes came on the market.
This receiver is the most common type among all "Trans Oceanic" receivers,
the production reached a number of 245'000 sets. It is the classic shortwave
travel radio of the fifties and is found in many collections.
The H500 is a quite heavy hollow state multiband radio, the set looks like
a black suitcase with a carrying handle, it's dimensions are 43 x 28 x 20 cm.
A metal lock at the front unlocks the big lid of the receiver, under the lid, You find the detachable "Wave Magnet".
The speaker grille takes the left third of the front panel.
The volume control acts as main switch, use the band selector pushbuttons to select the desired shortwave band and look for the corresponding band on the round dial. The dial marks are very coarse, so You have to search for the station and to identify it by the language and a spoken identification or interval signal. The H500 has no BFO for CW and single sideband reception, all these features have been found in commercial communication receivers only in the fifties, when the Trans Oceanic has been constructed.
In summary: the Zenith Trans Oceanic H500 as an absolute classic hollow state travel shortwave receiver with a receiver design dating from the fourties. It has been produced in quite large numbers and is a very niece piece in every colletion of shortwave radios. Of course, it's not the type of radio, You would take with You when travelling abroad, today. Even if You still can catch some overseas signals on the shortwave bands, they will remain the same as in the fifties, there are much better solid state travel radios available today.
At this place, I want to send all my thanks to Roy Johnson, who gave me his "family treasure" which became the first "T/O" in my collection.
