AWA Presentation: The origin of breadboarding

Many thanks to SWLing Post contributor, Mark (AE2EA), who writes:

Hi Thomas,

FYI, The AWA just posted a presentation by Andy Flowers, K0SM, about amateur radio transmitters from the 1920s & early 30s. Andy is a builder of beautiful early transmitters, among other ham radio pursuits like 10GHz and up microwave work.

Here’s the latest blurb from the AWA:

If you were an amateur radio operator 100 years ago, and wanted a transmitter, you had one choice, you built a breadboard transmitter from scratch, often with components you made yourself. Today, some hams still do this, with designs from the early years of ham radio. AWA member Andy Flowers, K0SM, is one of those modern day vintage transmitter breadboarders.

Join Andy as he explains how early radio amateurs built their own breadboard transmitters with handmade parts, and put them on the air without killing themselves (well, most of the time.)

Watch it here:

Many thanks to SWLing Post contributor, Mark (AE2EA), who shares the following announcement:

2021 marks the 100th year anniversary of the historic Transatlantic Tests, where radio amateurs using the call sign 1BCG were responsible for the first successful radio communication across the Atlantic Ocean on “short waves.”

On December 11, 2021 the Antique Wireless Association will recreate these historic transmissions on 160 meters from the Vintage Radio and Communications Museum of Connecticut, using a replica transmitter constructed by volunteers at the Antique Wireless Association. This special event is your opportunity to relive a historic moment in amateur radio history.
