The Armstrong

THIS BOOK IS SMALL BUT EXPLAINS A LOT ABOUT THE THINKING OF ARMSTRONG. HIS DESIGNS MADE USE OF TECHNOLOGY THAT IS STILL CONSIDE3RED WELL BEYOND ACADEMIC THINKING.THE FUNCTIONAL EXPLANATION OF WHAT HE DID IS IMPOSSIBLE WITHOUT THE MECHANICS OF THE THEORYS OF TRANSFORMERS AND THE RELATIONSHIPS OF POSITIVE AND NEGATIVE FEEDBACK WHEN EMPLOYED AT THE SAME TIME.SIXTY YEARS AGO I EXPLORED HIS RECEIVERS AND FOUND THEM EXTREMELY WELL BUILT AND FUNCTIONAL BEYOND ANY EXPECTATIONS FOR WHAT WAS IN THEM. OR, WHAT APPEARED TO BE IN THEM.I MAVE BUILT MANY REGENERATIVE CIRCUITS. SOME WORKED REALLY WELL SOME DID NOT. SOME EVEN WORKED AS WELL AS THE RECEIVERS BY HAZELTINE COMPANY AND MARCONI EQUIPMENT.I FOUND IT INTERESTING THAT ARMSTRONG MARKETED RECEIVERS INTENDED FOR VOICE AS WELL AS MORSE. NOT INTERCHANGABLE. THIS BOOK EXPLAINS THE DIFFERENCE, HOW AND WHY.DO NOT FOR ONE SECOND THINK THAT WITHOUT A LOT OF ENGINEERING EXPERIENCE YOU WILL FOLLOW THESE DESIGNS WITHOUT TAKING THE TIME TO LEARN THINGS YOU NEVER DREAMED EXISTED. OF COURSE ARMSTRONGS LATER DESIGNS MADE THESE DESIGNS OBSOLETE BUT WHEN YOU CONSIDER THE SIMPLICITY OF THEM AS FAR AS COMP0NENTS GO YOU ALSO REALIZE THAT IN A MORE PRIMATIVE WORLD THESE WILL BE THE BEST BILL OF FARE. ALSO KEEP IN MIND THAT ALL THOSE TOYS YOU NOW USE TO COMMAND YOUR LIGHTS YOUR CAR YOUR GARAGE DOOR ARE BASICALLY MICROMINATURE COPYS OF THE REGENERATIVE RECEIVERS OF YESTERYEAR. NOT THE SUPERHETRODYNE THAT CAME LATER; NO MIXERS; JUST OSCILLATING RECEIVERS.THERE IS ONLY ONE LIMITATION TO THE SENSATIVITY OF THE ARMSRONG RECEIVER AND THAT IS NOISE. THINK OF IT AS MODERN DNA PROCESSES WHERE THE INFORMATION IS USED TO REPRODUCE IT'S SELF UNTIL YOU HAVE SOMETHING LARGE ENOUGH TO BE USEFUL. THIS IS WHAT IT IS ALL ABOUT ONE VACUUM TUBE CAN PRODUCE AN AUDIBLE SIGNAL FROM SOMETHING SO WEAK MODERN RECEIVERS WILL NEVER FIND IT. ALL YOU HAVE TO DO IS LET IT REGENERATE AND CONTROL THE PROCESS.
