It looks like as if Hallicrafters might have found some inspiration for their TW-1000A from some Zenith receivers, the Trans Oceanic series had an immense success as travel shortwave receivers, and the Hallicrafters has some similarities to the Zenith H600 and even comes with a tone control similar to the Zenith "Radioorgan" and a detachable shortwave antenna.

Single conversion, I.F. 455 kHz

Analog dial with spread shortwave bands

AM

Powered by batteries (needs HT / B+ batteries !)or mains 110V AC/DC, with ballast adaptor 1X1438, AC/DC use from 220V is possible.

The heavy "suitcase" travel radio Hallicrafters TW-1000A has an appearence very similar to the Zenith Trans Oceanic H600: With it's dimensions of 43 x 30 x 20 cm and a weight of around 10 kg, You can image, how "heavy" it has been to keep contact with news from home on a trip abroad.

The receiver has - like the Trans Oceanic - a cover which can be tilted up, it covers the front panel control when the receiver is carried around. At the top face, next to the carrying handle, You find a telescopic antenna for shortwaves, the receiver has an internal ferrite antenna for mediumwaves and a detachable shortwave loop antenna which can be attached to a window in a train or a hotel by means of two suckers. The upper compartment accessible at the rear is meant to store the large and heavy battery for heaters and anode / B+ voltage, these batteries are not sold anymore for many years.

The set has only a few front panel controls: the on/off / volume switch and the band selector switch are located at both sides of the oval speaker. Four little sliding switches are used for tone control, they do their job slightly better then the simple speech/music selector.
The frequency dial is of a horizontal kind and slightly wider then the one of the Trans Oceanic "twin". A tiny red mechanical indicator indicates the active band.
The arrangement of the frequency bands on the dial is slightly confusing. The yellow dial in the middle is the langwave band with the designation NAVIGATION, it is used for the reception of longwave beacons for maritime navigation - in the U.S., there are no broadcasting stations on longwaves.
The bottom dial is the mediumwave dial with the designation STANDARD BROADCAST, small marks "Civil Defense" indicate the emergency frequencies used by the American Civil Defense organisation.
Uppermost is the dial of the tropical band 1,6 - 3,9 MHz, band 5 covers the frequencies 3,9 - 8 MHz with the tropical bands 75 - 60 Meter and the 49 as well as the 41 m broadcast band, the latter is not used for broadcast transmissions in the U.S.
The bandspread dial for the 31 m band (9,22 - 10,3 MHz) is band No. 4, the 25 m band (11.4 - 12,3) called band 6 and the 19 and 16 m bands (14,2 - 15,7 and 17,3 - 18,2 MHz) are located nearly topmost on the dial.
The arrangement of ther frequency bands on the dial is not in ascending order, but Hallicrafters seem to have anticipated some use of out of band channels by American broadcasters, as many out of band frequencies are covered - but the radio is not general coverage.

The Hallicrafters TW-1000A can be considered as a collector's item today: no one will bother with such a heavy and bulky radio on an airplane trip. The batteries are not sold anymore, in Europe, You need a 220/110 V transformer to operate the radio.
In the collection, the TW-1000A is a milestone in the development from large hollow state radios to the small portable transistor radios.
