R.C. & L.F. Hall, Houston, 1944

1944FebRadioRetailingThe duo behind the counter here are Dick Hall, W5EIB, and his wife Lillian Hall, W5EUG, owners of R.C. & L.F. Hall, 1015 Caroline St., Houston, Texas.

Their business began when they found a lack of interest by local dealers for hams, and Dick began stocking a few parts in his home. As the stock started to overtake their entire house, they moved to a downtown location. As they anticipated American entry into the war, their business focused on industrial and marine parts. When war came, they knew the whereabouts of most amateur transmitters and receivers in the area, and facilitated sales of that equipment to the military.

The Halls discovered that dealers and hams don’t really mix. The dealer, seeking marine and industrial parts, knew just what he wanted, whereas the hams wanted a place that talked their language. They anticipated a big future for their business after the war, as hams came on the air, and as FM and TV stations would create new markets.

The picture and accompanying article appeared in Radio Retailing, Feburary 1944. This eBay listing shows a 1946 ad for their business, which by then had locations in Beaumont, Dallas, and Galveston, in addition to the Houston store, which was then at 1306 Clay Avenue.



The House Wired For Radio, 1939

1939FebRadioCraftEighty-five years ago, the February 1939 issue of Radio Craft shows how to wire your house for radio. And like Mr. Green, you could be serene knowing that there was one in every room. Actually, there was only one radio, a top-of-the-line RCA Victor model U-130. Speakers were mounted in each room. But in addition, the set allowed the use of a wired remote control, so controls were mounted on the walls of most rooms. But if walking over to the wall proved too stressful, there was also an armchair remote, which could be plugged in to a nearby socket.

The installation also incorporated a set of Model 446 Aristocrat “TELECHIMES” by General Kontrolar company, Inc., which could be used to elegantly page family members throughout the house.



1939 Code Practice Set

1939FebPMEighty-five years ago, it was customary to put on a tie before learning Morse code, and this young man honored that custom. He’s practicing with a self-explanatory device shown in the February 1939 issue of Popular Mechanics.

To hear perfect code, he simply runs the test lead over the cardboard cutout over a copper sheet, and the code sends itself. We’ve seen similar ideas before, such as here.



While London Burned: Scout Edward John Cox

EdwardJohnCoxThe February 1944 issue of Boys’ Life carried the stories of a number of British Scouts who had demonstrated bravery during World War II. Shown here is Scout Edward John Cox. During a heavy air raid, he was stationed at his post on the roof of St. George’s-in-the-East Church.

His mother and younger sisters had taken refuge in the crypt under the church. Incendiary bombs crashed around him, and he seized sandbags to quickly extinguish them. But as the raid continued, a big bomb blast into the church belfry, which almost immediately became a roaring mass of flames.

One of the men around him realized that eventually, the belfry would collapse, causing the massive bells to fall through the church and into the crypt. He raced down and gasped out the news to the marshal. Together, they started evacuating the mothers and children. Scout Cox kept going back again and again until all of the children were evacuated.

The last person had just been evacuated when the timbers of the belfry broke through the church and into the crypt.

The UK Scout Association awarded Scout Cox the Silver Cross, an award for acts of bravery in the face of danger where life has been at considerable risk.



1924 Telephone Workers: Risking Life and Limb

1924FebBLA hundred years ago, the telephone had become an essential part of American life, and the public had come to take it for granted as part of their normal business and social lives, as well as relying upon it in emergencies.

But The Telephone Company and its workers didn’t take it for granted. Despite fire or storm or flood, the telephone operator stuck to her switchboard. And the lineman and a quarter million employees risked life, limb, and even health to make sure that messages continued to go through.

All the public had to do for all of this was to pay the moderate cost.

This ad appeared in the February 1924 issue of Boys’ Life.



1939 British One-Tube Regen

1939FebPracMechThe plans for this one-tube–er, I mean one-valve–regenerative receiver appeared 85 years ago this month in the January 1939 issue of Practical Mechanics.

The article begins by noting that “the small receiver is apt to be despised in these days of 7 and 8 -valve superhets, there is still a very wide field of application for the simple one-valver. Many schoolmasters, for in- stance, have asked for details of a set which may be used as a demonstrating model, either for handycraft instruction, or to explain many of the theories underlying modern radio technique.”

The circuit relies upon a pre-made coil, which is no doubt unobtainium these days. But the article does describe how to make a very similar coil, which can be used with slight modification of the circuit. Either way, the set did tune both longwave and mediumwave bands, thanks to a band switch which shorted out the longwave portion of the coil. The set uses a D210, which is a British model, but almost any triode would probably work well.

1939 Typing Class

1939JanRadioRetailingAs shown here in the January 1939 issue of Radio Retailing, it looks like a few boys 85 years ago got the memo that the place to meet girls (and learn a useful skill) was to take typing class.

And this school was doing it right. Above the blackboard, you can see a loudspeaker, which is playing an amplified recording. The magazine notes that this delivers a rhythm, which is desirable for the student typists to develop a uniform touch.



1974 Digital Watch

1974JanPEFifty years ago, the hobbyist with nimble fingers and a sharp eye could have their own digital watch, thanks to this project in the January 1974 issue of Popular Electronics.

If you bought one, it would set you back $200, but you could make your own for about $80. The construction article gave the source for the case, you could make the small PC board, or you could buy the whole thing as a kit. If the tip on your soldering iron wasn’t small enough, the article suggested attaching a piece of copper wire and filing down the end. Accuracy was said to be several seconds a month.



1964 Grocery Prices

1964Jan27PghPostGaz1

For a snapshot of grocery prices sixty years ago, these ads appeared in the January 27, 1964, issue of the Pittsburgh Post Gazette.

Some of these prices look like a bargain, but there’s been a lot of inflation since 1964. In fact, 1964 was the last year that American coins were made out of silver. So one dollar meant one silver dollar, or four silver quarters, or ten silver dimes, each about one ounce of silver. Today, that ounce of silver is worth about $23, so you can multiply these prices by 23 for a fairly good idea of the value in today’s money. So the hamburger for 39 cents a pound is about the same as $9 per pound today.

If you were shopping for dinner 60 years ago, what would you buy?

1949 Combination Receiver/Signal Generator

Screenshot 2024-01-12 12.43.23 PMThis utilitarian-looking three-tube British device appeared in Practical Wireless 75 years ago this month, January 1949. It has considerable utility, as it functions as both a regenerative receiver and signal generator.

The regenerative receiver, of course, causes oscillation that can be radiated through the antenna jack. But this circuit does one better, because it turns the audio amplifier into an oscillator, which modulates the signal. Therefore, when working on another piece of equipment, you have a handy source of tone modulated RF. And when you’re done troubleshooting your other device, you can tune in programs from 3000 to 10 meters. Thanks to the second harmonic, you can use it as a signal generator up to five meters.
