Home Guest book  Contact me THE SPIRIT OF THE GOLDEN AGE OF RADIO My Vintage Radios and other articles, projects and essays told as historical and biographical stories for my amusement and your entertainment by John L. Fuhring Beautiful antique radios I restored. My Crosley 817 after 50 years of hiding My 1936 "King's Speech" Radio A very rare 1936 Troy Radio Summer of '42 Philco Portable radio A very rare Farnsworth 1942 portable radio My restored Hallicrafter radios. A World War Two GI's shortwave radio Captain Allan Hancock's EC-1b From the junk pile of the Hancock Flying Field My redesigned S-38b radio Rebuilt as a kit. My improved S-120 radio Finally working right after only 50 years Radios I have restored for others The first practical transistor radio A rare Remler Radio from the mid 1940's My homebrewed  and crystal radios. My first amplified radio An Armstrong regnerative radio I built in 1958 and updated for better performance. My Magnum Opus Homebrewed Radio A transceiver for the amateur radio bands. A high performance crystal radio Excellent performance from an unamplified radio. A high performance crystal radio kit designed as a project for science students My Regenerative Shortwave Radio Project A shortwave radio based on Armstrong's regenerative principle. A homemade broadcast band transmitter So you will have something decent to listen to. An Armstrong "Crystal" Radio From "The Old Geezer Electrician" A recent update of my first amplified radio from 1958 Another Armstrong regenerative radio A nicer looking version of the Geezerola and made to resemble the first commercial regenerative radio, the 1921 Aeriola Senior. Converting your crystal radio to an Armstrong regenerative radio A simple but very effective BFO you can build and install in your radio. Essays on basic radio design & safety. Basic elements of the superheterodyne radio One of Armstrong's most enduring inventions. An essay on the first practical radio and notes on detectors used in later radios. An essay on Hot Chassis radio safety A very important warning and detailed instructions on how to make All American Five (AA5) radios safe to work on and to use.  AA5 radios should not be plugged in until made safe. An essay on Shackleton's missing radio gear and a description of a typical receiver and transmitter of the era. An essay on radio technology circa 1914 Great Milestones in Electronic Technology: A German company, Telefunken, manufactured the first robocops in 1921. Relying on early vacuum tube technology, they were not very successful. The delicate glass triode tubes were easily damaged in violent confrontations with the period's supervillains.  By the end of the decade, all robocops were decommissioned thus enabling the infamous criminal take-over of Germany and the horrific aftermath that still haunts the world. Arms manufacturer Lockheed's famous 1988 model robocop. Practical robocops of today use solid state electronics and, ruggedized, are more than a match for today's supervillains. An early model "Attention Getting Device" from 1923. Attention getting devices have been used by school children for hundreds of years, but were never very effective until the first good triode amplifier tubes became available after 1920.  Today all attention getting devices use transistors and integrated circuits and are microprocessor controlled. AMATEUR RADIO STATION WA6TLP Circa 1978, I get my homebrewed radio working and on the air. It had several serious bugs, but in 2011 and again in 2014, each circuit was evaluated and many were reworked for better stability and better performance.  It still uses valves (tubes) as shown, but is now digitally synthesized and drift free. First semi-driverless vehicle circa 1970. This car was decades ahead of its time with semi-intelligent steering, homing and crash avoidance.  The energy source is "green" (grass) and entirely renewable.  It was later found that some of the emissions are powerful greenhouse gases.
