American Leader Midget Pocket Radio, 1938

1938Apr23RadioGuideEighty years ago today, the April 23, 1938, issue of Radio Guide carried this ad for a midget pocket radio from American Leader, 1606 W. 78th Street, Chicago.  Since it needs “no batteries, tubes, or electrical connection,” it appears to be a crystal set.  The ad promised that you can use it anywhere–“in auto, bed, office, hotel, etc.” and that it’s not a toy.  The set sold for $2.99, and the seller covered the postage on cash orders, or you paid a few cents if sent C.O.D.

I suspect that the antenna and ground connections would get a bit tricky in a car,   But subsequent research reveals that it was a quite attractive little crystal set.  The image below appears at Wikimedia Commons:

The caption of that photo reveals that the headphone is stored in a compartment inside the set.  So as long as you had an antenna and ground connection nearby, the set probably was something more than just a toy.

1958 Soviet Roadtrip

1958FebPS1958FebPS1Sixty years ago this month, at the height of the Cold War, the February 1958 issue of Popular Science had as its cover feature an account of a motor trip by two Americans, with their dutiful Intourist guide in the back seat, across the Soviet Union from Brest to Moscow and then south to Yalta.

The author, Harry Walton, along with Dennis Michael O’Connor, made the trip in a Belgian-made 1957 Rambler station wagon. After reciting the preconceptions he had of the trip, Walton writes:

The preconceptions were wrong. The Russians I met were not hostile, and the roads and mechanics were first-rate. In several cities I met friendly, curious, wide-awake students (including some who regularly read Popular Science in the technical library). Often I talked with earnest, unsmiling but not unfriendly adults who took to hear their government’s much-repeated slogan: “Beat America.” Everywhere I saw evidences of a dedicated national effort to cram into two decades the industrial revolution that has taken the West two centuries.”

Hammarlund Super Pro Console, 1937

1937NovRadioWorld

The Hammarlund Super-Pro series of receivers represent one of the best performing prewar communications receivers. The line was first introduced in 1936, and when war came, they took the BC-779 nameplate for the military version.

Thousands of the models making up the series rolled off the Hammarlund assembly line over the years, but one of the rarest variations is shown here, and it appears that only about 70 were made.  Inspired, no doubt, by high-end home consoles such as the McMurdo Silver, Hammarlund decided to move the set from the ham shack to the living room.  So they put it in the cabinet shown here, as seen in the August 1937 issue of Radio World.

But it wasn’t just any cabinet that they slapped it into.  As the accompanying article explains, the cabinet was carefully designed for its audio qualities, particularly the bass response.  There’s no doubt that the set was a top performer, and I’m sure it sounded good.  Since it was destined for the living room, a few modifications were made.  For example, even though the set had a BFO for listening to code, the BFO pitch was not adjustable from the front panel.

But it was a flop as far as sales.  As the Radio Boulevard site explains, “it just wouldn’t do for hams – it had no BFO on the front and it was too big. It didn’t have the Scott or McMurdo chrome chassis – how could you impress your friends?”  The site does have a picture of a nicely restored specimen, owned by AA6S.  From the color picture, it does look like a communications receiver thinly disguised as a console.  The front panel is faux walnut, and just looks out of place.  It’s not quite a communications receiver, and it’s not quite a console.

I’d love to have one in my living room.  And as a loyal reader, you would love to have one.  But let’s face it, nobody else would want one!
