Comparing Link Coupling and Pi Networks with the AWA 6AQ5 Transmitter AWA Communication Technologies Museum 2025-06-30 | Jake Graham, KC7WXD, built a 1 tube CW transmitter and experimented with both a link coupled tank circuit and a pi network in order to match the high impedance tube output into a 50 ohm load. It's what hams routinely did before transmitters demanded no more from from them than their microwave oven or toaster. The transmitter is built using a printed circuit board from the Antique Wireless Association, and can be purchased at the link below:antiquewireless.org/homepage/pcb-item-12This bare printed circuit board (PCB) can serve as a component of a 6AQ5 transmitter for operation by licensed radio amateurs. This printed circuit board component and the resulting transmitter are intended for experienced persons. The completed unit and associated components produce potentially dangerous voltages.This single-tube CW crystal transmitter PCB is for 40m and 80m and it may work on other amateur bands or modes. Up to 8 watts RF output into 50 ohms, with a nice tone using good FT-243 or HC-49 (modern) crystals. Importantly, with proper tuning, harmonics can be -49dB at the output of a pi network. This offering is for the bare PCB only and no other components are included. A representative parts list (with Mouser and Tube Depot part numbers) along with construction notes ship with the PCB. In addition, this webpage contains the schematic and several other resources, which are available for download (below), that may assist the builder. Nominal PCB dimensions: 2.9″ x 2.9″. The cost of the parts mounted on the PCB (not including the tube, crystal or shipping) is about $10, more or less. You’ll also need to raid your junkbox for a B+ supply, heater supply, and parts for the pi network or linked-coupled output.

Fading and Blasting - Invention of the AVC and AGC circuit and the Inventor Harold Wheeler AWA Communication Technologies Museum 2025-02-21 | Early AM radio receivers were known for their inconsistent volume which was caused by the vagaries of signal propagation, but in 1925, Harold Alden Wheeler invented automatic volume control (AVC) and obtained a patent. By the early 1930s most new commercial broadcast receivers included automatic volume control.During his education Wheeler worked part-time at the National Bureau of Standards' Radio Laboratory, then from 1922 onwards at Stevens Institute of Technology, with Prof. Louis Alan Hazeltine, after discovering that they had independently invented the Neutrodyne receiver.In this AWA Shares presentation Mike Molnar examines Wheeler's AGC and AVC circuits which were among the 180 groundbreaking inventions for which he received patents.AWA member Mike Molnar founded Diagnostic Services Inc. in 1983.

AWA Deep Dive Podcast - Armstrongs 1930s FM Tests at the Empire State Building AWA Communication Technologies Museum 2025-02-18 | This podcast is based on a paper written by Thomas J. Buzalski, the former chief transmitter engineer for NBC in New York. You can read his paper in the 1986 issue of the AWA Review here:antiquewireless.org/homepage/awa-review-archiveThe paper written from the unique vantage point of an engineer who worked closely with Major E. H. Armstrong on the early development of frequency modulation (FM), as an aural broadcasting service. Some qualities of Howard Armstrong as an engineer, inventor and human being are disclosed, not often found in print. His system of frequency modulation was in some respects a contradiction of accepted theory in that it achieved a reduction in noise level by using a channel having greater rather than smaller bandwidth. Armstrong was inclined frequently to say that one oft he difficulties in what he was doing was that people so often knew so many things that weren't so.The development of Armstrong's system of FM stimulated work on information theory which provided a better understanding of fundamental communications principles which, in turn, has guided the design of today's complex systems.This audio content was produced with AI.Help us preserve the history of electronic communications by becoming a member of the Antique Wireless Association at: antiquewireless.org/homepage/join-or-renew-membershipSubscribe to the Antique Wireless Museum channel and you'll receive news of our latest video uploads.

Fraudsters and Charlatans: The Problem of Fake News on the Radio, 1920-1930. AWA Communication Technologies Museum 2024-04-18 | When commercial radio came onto the scene in 1920, listeners were amazed. This new mass medium brought music, sports, religious services, and so much more into their homes for free. But amidst the singers, and the sports reports, and the religious sermons, there were also some fraudsters and charlatans. Early radio was an all-volunteer enterprise, and on many local stations, informational talks were an easy way to fill up some time. Some of the talks were educational, given by professors or business leaders. But others were given by folks with fake credentials and dubious expertise. They offered miracle cures for diseases, or promised to help you speak to your dead relatives, or trafficked in bigotry (the Ku Klux Klan even owned an early station). Donna Halper will take you back to the first decade of radio, when the rules were still being written, a time when the public was much more trusting, and they tended to believe what they heard on their favorite station. You'll meet some of the era's earliest fraudsters, as well as a few folks who tried to confront them.Help us preserve the history of electronic communications by becoming a member of the Antique Wireless Association at: antiquewireless.orgSubscribe to the Antique Wireless Museum channel and you'll receive news of our latest video uploads.

A Band Switching Game Changer - Nationals “Movable-Coil Tuning Unit” AWA Communication Technologies Museum 2023-09-22 | ln the mid 1930s James Millen and the National Company, Inc announced an innovation called the “Movable-Coil Tuning Unit”. The first of these “coil-catacomb” or “sliding-coil” receivers was introduced in 1936 and represented the first truly high-performance communication receivers that did not use plug-in coil sets. This receiver series continued to evolve and expand through WW2 and beyond with the addition of direct-reading dials and a single unified band-change and tuning control system. By 1949 over 60 different receiver variants had been manufactured and many of these show up at swap meets and hamfests usually at very reasonable prices.Antique Wireless Association Member and communications historian Brian Harrison, KN4R, tells the story of these revolutionary receivers in this presentation from the AWA Shares series.Help us preserve the history of electronic communications by becoming a member of the Antique Wireless Association at: antiquewireless.org/homepage/membershipSubscribe to the Antique Wireless Museum channel and you'll receive news of our latest video uploads.
A Fully-Automatic RotoBug by WB9LPU AWA Communication Technologies Museum 2023-09-10 | Fully-automatic bugs are quite scarce. Those that do exist, like the Melehan Valiant and the GHD bug, are beautiful pieces of machinery, but they are rather difficult to adjust, since the dot and dash elements are each generated by their own separate pendulum. Rich Meiss, WB9LPU, set out to design a system in which both dots and dashes were made by the same oscillating pendulum. This would permit speed to be varied over a wide range without affecting the ratio of dot-to-dash duration, but it could also allow independent adjustment of the relative weights of the elements. The result of some recent experiments has led to this rotary bug of original design.

Preserving Your Antique Radio Collection AWA Communication Technologies Museum 2023-06-23 | Preservation (as opposed to restoration) is concerned with prevention of decay. The talk will start from very general preservation policy basics, then explain that preventing decay in practice involves understanding what materials are present, what goes wrong with those materials, and what environmental forces and human actions can influence the rate of decay. Storage conditions play a pivotal role in mitigating all such damage. The talk will present examples of environment-related deterioration such as warping of tenite grilles (chemical change), metal corrosion (rusting chassis parts, capacitor failures), mold growth (on everything) and mechanical damage (cracking of wood). Beyond these material issues, survival of collections beyond the lifetime of the collector (or the lifetime of the collector’s fascination with them) often depends on the collector’s willingness to engage with institutions like the AWA Museum to understand their mission, policies and resources. Planning for the generation of stewardship that comes after the original collector is a vital part of preserving any type of collection. Brief Bio of James Reilly:James M. Reilly, B.A., M.A., founded and directed the Image Permanence Institute at Rochester Institute of Technology for 32 years until his retirement in 2017.

Cable and Wireless - The History of Trans-Oceanic Communication AWA Communication Technologies Museum 2023-05-15 | Although the first undersea telegraph cable was installed in the mid 1800s, it would be another 100 years before the first transatlantic telephone cable, the TAT-1, went into service in 1956. Many other communication technologies have developed since then, but undersea cables still provide the bulk of all transoceanic communication bandwidth today. Undersea Cable Historian Bill Burns tells the story of how cables came to dominate communications in this fascinating presentation at the Antique Wireless Association 2022 Conference. To learn more about cable history visit atlantic-cable.comPlease note that this was made from a safety audio copy because there was a technical issue with the capture directly from Bill’s microphone.
