RCA,  Philco, GE, Admiral...these are the big names American hams remember as the leaders in consumer electronics manufacturing in the "mid-century" period that this site is focused on.   But the world was a much different place in those pre-globalization days, and while there was some export to other countries, for the most part domestic manufacturers of similar stature all over the world supplied similar products to their local markets.   This is why a portable radio in Japan might be a "National", or a Telefunken or Normende in Germany.    In England,  it might well be a Bush radio - made by Rank  Bush Murphy Ltd, in it's factories at Chiswick and Ernesettle.   Like its US counterparts, the original company is long gone, a victim of cheap labor and changing technologies, but the brand lives on,  owned by Sainsbury's, the parent company of the retailer Argos, a catalog and retail operation.

This film, produced by the company in 1961 is typical of what would have been seen in any consumer electronics factories anywhere in the world.    Discrete components assembled and hand-soldered,  with only minimal automation.    Trained operators performed a specific set of tasks within a short time period and then the assembly was moved along the assembly line to the next operator who would continue the process until complete.   Testing and alignment was done manually by skilled operators, overseen by  technicians.   Production engineers were available for consultation when problems arose and each product with sufficient volume was built on it's own dedicated assembly line.   Clearly these were very labor-intensive operations and that is what brought them to an end, when automation and low-cost manufacturing alternatives became compelling.     But it's a nice look back in time to how electronic products were built during the "DX-60 era".

 


   Anyone who caught one of the Emergency Action Notifications (EAN) transmitted by the US Air Force on the HF bands remembers this phrase.But not many know how the EAN is actually used by our military.   This re-creation of a Minuteman III Launch Control Facilitliy (LCF) in Utah provides a realistic view of what happens when an EAN is received by a missile control crew,  60 feet under...  READ MORE

   If you're a long-time ham you might know what the smeary figure-8 pattern is....Back in the Novice era,  many used crystals purchased from suppliers like JAN Crystals who purchased large quantities of military surplus crystals and reground them for the ham bands.   That's why they were cheap, but also why you couldn't get a specific frequency as they'd grind by a formula and is long...  READ MORE

   Ron K5HZ has been building equipment since he first got his ham license in the early 60s, and while he has other transmitters, all it took to build a new one was finding a "free to good home" power transformer at a hamfest.    It also gave him a chance to try using a couple of Compactron tubes that had caught his eye - the 6T10 dual pentode and the 6GE5 beam power pentode that was d...  READ MORE

   If you build almost anything electronic, chances are good you've purchased parts from DigiKey Electronics.  But did you know that DigiKey - now one of the world's largest electronics distributors - started out as a ham radio company?"More than 50 years ago, a digital electronic device designed to generate uniform Morse characters and spaces was made available for sale by amateur radio enthusi...  READ MORE
