Zenith Model 7G605 "Clipper" TransOceanic Radio (1942)

Here you see the legendary "Clipper," the original TransOceanic portable that launched a radio dynasty lasting 40 years.

The Zenith TransOceanic was the brainchild of Commander Eugene F. McDonald, the head of Zenith and a dedicated traveler and yachtsman. Frustrated that ordinary Zenith sets didn't perform well in remote areas, he ordered his engineers to develop a new portable that could receive shortwave broadcasts anywhere in the world.

After some two years of development, with McDonald himself testing the prototypes, Zenith produced a rugged, utilitarian set that could receive five shortwave bands (49, 31, 25, 19, and 16 meters) in addition to regular AM broadcasts. The quality standards were high, as was the price—$75, which represents almost $700 in today's dollars.

War Baby

Model 7G605's history is intimately connected with World War II. It began manufacturing around October, 1941 and went on sale to the public in January, 1942.

That was just in time to supply a few lucky World War II soldiers with a rugged portable that they and their buddies could use anywhere in the world. TransOceanic ads from these years feature testimonials from grateful owners, describing how their faithful sets survived dunking, falling from jeeps, extreme climactic conditions and other misadventures in faraway lands, all the the while providing welcome news and entertainment from home.

The last Clipper was built in April, 1942, when the US government shut down all domestic radio manufacturing to provide for military needs. My Clipper bears serial number T852064, indicating it was made in the first production run of 10,000 units.

Zenith took advantage of the wartime experience to cloak the TransOceanic with an aura of glamor that remains to this day. The legend is firmly grounded in reality, however. For its time, the original TransOceanic was indeed a high-performance set, built to high standards. And Zenith maintained those standards for the TransOceanic line over a period of decades.

Description

Like its cheaper "companion" set, the 6G601M Universal, the Clipper has a cabinet that's basically a little suitcase, with detachable front cover and hinged back. (The front cover looks a little off-kilter here, but that's because I wasn't quite on-center when I took the photo.)

Most Clippers feature the bomber grille pattern shown here. A few sets in the first production run used the same sailboat design as the 6G601M, but the sailboat was soon replaced by the bomber by order of the patriotic Commander McDonald.

For a 1940s appliance, this set is quite user-friendly, with simple controls and integrated instructional material. To the far right are the six bandswitches, each marked to indicate the best time of day for reception on its band. Further operating instructions appear on a card permanently mounted inside the front cover.

The round power/volume and tuning knobs feature a distinctive "lightning Z" Zenith logo. Above them is the Radiorgan, a group of four tone switches marked Treble, Voice, Alto, and Bass.

The dramatic gold and black tuning dial features a delicate pointer that repeats the lightning Z emblem.

Zenith made much of the TransOceanic's distinctive antennas. The large telescopic antenna was dubbed the Waverod. It can be rotated upright, then extended vertically.

The second antenna is called the WaveMagnet, a moniker that Zenith applied to many of their antennas over the years. It is a big loop antenna at the end of a flexible straplike cable which you can plug into the back of the radio. The body of the antenna is fitted with rubber suction cups. When not in use, it stows away with clips inside the back cover.

Both antennas can be seen in the next photo.

With its cable and suction cups, the WaveMagnet could be attached to the window of a train, airplane, or boat. Ordinary radios might be silenced inside those metal vehicles, but you could improve your reception by sticking your WaveMagnet onto the window next to you. This design was patented by Zenith and it persisted until the very end of the TransOceanic era.

The rubber suction cups on WaveMagnet antennas always become dried and stiff with age. I have been told that you can revive their pliability by soaking the suction cups in a solution of WD-40 for several days—a procedure that I haven't yet tried.

This radio employs "loktal" type tubes which snap securely into their sockets. The six tubes are: 117ZG6, 3Q5, 1LN5, 1LA6, 1LN5, 1LD5. The Clipper can use either line current (110-volt AC or DC) or DC power from a large battery pack.

My set has its original cloth-covered power cord. Headphones were available as an option. They plugged into a two-pronged jack in the back of the chassis.

Apart from a broken leather handle and some minor case dings, all my Clipper really needs is some cleaning and a routine electronic restoration. You can buy replacement leather handles at Antique Electronic Supply.

Zenith made a number of refinements in the TransOceanic during its long lifespan, but this basic design persisted throughout the tube years. The other articles in this section chronicle how the TransOceanic evolved from this early effort to its final incarnation, the all-transistor R-7000.
