1944 British 3 Tube Receiver

1944JunePracWirThe plans for this attractive and compact receiver were contained in the June 1944 issue of the British magazine Practical Wireless. Even though there was an invasion of Europe going on, the magazine reassured that the parts were available from their advertisers at a low price.

The set gave good reproduction, and the volume was found to be ample for all normal occasions, and it was said to be a good family receiver.

The B+ was supplied by a 120 volt battery, with filament and grid bias batteries also required.

Taking the Radio on Vacation, 1924

Screenshot 2024-05-22 11.11.30 AMA hundred years ago this month, the June 1944 issue of Popular Science published some pointers on taking your radio with you on vacation. The magazine quoted Hiram Percy Maxim as predicting that within five years, most automobiles would be equipped with a radio. In the meantime, the magazine offered some suggestions.

The most critical element was the antenna, and it noted that a long aerial would always outperform a loop, especially if your vacation took you a long distance from the closest station. Fortunately, there was almost always something available for getting the wire in the air, as long as you used a bit of ingenuity. The photo above shows a radio fan who got his set working on a fishing expedition along the Green River near Seattle.

1939 Portable Crystal Set

1939JunPM1939JunPM2This woman, like most radio listeners 85 years ago, knew that a good crystal set would pull in local stations with ample volume and excellent tone, as long as an antenna and ground were available. She took advantage of this knowledge and constructed the low-cost (under a dollar) pocket size crystal set with built-in headphone. The antenna and ground leads had clips on the end, so it was an easy matter to clip it to a telephone, as she did here, or even to a metal drain pipe or water pipe.

As long as the building was not of metal construction, this was said to pull in stations from 2-12 miles away. At home with a long outside antenna, receptions of powerful stations 30 miles away was possible.

The design is from the June 1939 issue of Popular Mechanics.



1920s-Era Regen from 1974

1974ElemElec1Fifty years ago this month, the May 1974 issue of Elementary Electronics showed how to build this receiver, which dated back another fifty years. It was dubbed an “antennaless” one-tube regen, and was said to work well without an outdoor antenna, instead using only a ground connection to a water pipe.

It uses two spiderweb coils, a type 30 tube (although others are possible), a variable capacitor, and only one resistor and capacitor.

I wasn’t able to find the original design, but according to the 1974 article, it was taken from an issue of Radio News from the “early 1920s.”

1939 Sears BC-SW Radio-Phono

1939May28SearsIf you were in the market for a new radio-phono 85 years ago, Sears was the place to go.  They would give you a liberal allowance for your trade-in.  For only $49.95 plus your old radio (or just $5 down), you could go home with this two-band receiver.  The broadcast band went up to 1720 kHz, so you would be able to pull in police calls.  And the 6-18 MHz shortwave band meant that you could listen to the news direct from Europe.

The ad appeared in the May 28, 1939, issue of the Washington Evening Star.



Wartime Jobs for Women: 1944

1944MayRadioMirror2These ads appeared eighty years ago this month in the May 1944 issue of Radio Mirror.Preview to encourage women to do their patriotic duty and get a job.

The ad below, sponsored by Pharma- Craft Corporation, makers of Fresh Underarm Deodorant Cream, advised women that the more of them hit the workforce, the faster the war would be over.  If they didn’t do their part, it could be a month longer or a year longer than it otherwise would be.

The ad at left, published by the makers of Kleenex, gives some more practical advice for the woman who thinks she knows only housework.  It reminds her that if she’s ever cooked or served meals, there were plenty of essential jobs waiting for her in hotels and restaurants.  If she liked shopping, then she would probably be a good salesperson, since it was just like shopping–in reverse.  Similarly, if she knew how to do washing or ironing, there were laundries in need of employees.  Finally, if she was good with books, she could enlist in one of the armed services, freeing up a man to fight.

Battery Charging by Phone, 1924

Screenshot 2024-05-06 1.07.37 PMA hundred years ago, if your radio battery was dead, you could get it charged by phone, kind of. You could call before 10:00 AM, the service station would come and pick it up, and you would have it back in time to pull in the DX that evening.
