Jesson will describe the genesis of this best-of-breed interception receiver initiated by David Sarnoff’s product leadership in order to exc eed allied design and production requirements. What makes this interceptio n receiver world-class and of interest to TCNJ engineering students? What were the Y- stations which were operated by Ham Radio operators and specia lly trained house-wives? How was German wireless traffic intercepted and f ollowed by Y-station (mostly women operators)\, traffic location analyzed (Gordon Welchman pioneered) and traffic decrypted (Alan Turing and Gordon Welchman)? In addition\, Jonathan Allen will speak about the detailed desi gn of the AR-88 and report on his excellent progress he has made in his re storation work at the Sarnoff Museum on the TCNJ Campus.\n\nRestoration of Alan Turing's Preferred Interception Receiver\, the RCA AR-88\; RCA's gre atest communications receiver\n\nAbstract - During WWII\, the interception of German encrypted wireless communication by Britain's many Y-stations w here operators\, listening to banks of RCA AR-88 receivers\, provided the captured encrypted messages in order for Bletchley Park to then process th ese messages into plaintext. Messages to be decrypted were handed to Alan Turing's - of the movie's Imitation Game fame - Hut 8 team at Bletchley Pa rk. Often overshadowed by the truly great Alan Turing\, the unsung heroes I found were the intercept\, or Y-station\, operators\, Gordon Welchman (H ut 6)\, and David Sarnoff and Joe will explain how their ground-breaking m ethods have been adopted by today's NSA!\n\nJoe will describe the design r equirements issued from RCA's David Sarnoff to his engineering team where he issued tough-and-expensive specifications and production delivery deman ds. RCA production was focused in Camden\, NJ but the international WWII p artner (Soviet\, British\, and Canadian) demand was handled by RCA's Expor t Sales under Charles Roberts in Camden\, New Jersey. Joe will discuss the design requirements through winning through performance and contrast the AR-88 receiver with the competitive receiver\,of its day\, e.g. National\; s HRO. Jonathan Allen will speak about his excellent progress he has made in his restoration work at the Sarnoff Museum on the TCNJ Campus.\n\nFinal ly\, Joe asked his TCNJ Electronics Lab students\, as a final Lab project\ , to compare a SPICE RF bandpass AR-88 filter simulation with a vacuum tub e SPICE library model derived from modifying a (biased) FET amplifier mode l. He will show these results generated by our Lab students. As a third-ge neration New Jersey native researching WWII communications\, I was proud o f the leadership shown by David Sarnoff and the multiple (estimated at 2) year reduction of the duration of WWII by the great work at Bletchley Park .\n\nCo-sponsored by: IEEE New Jersey Coast\n\nSpeaker(s): Joe Jesson\, Jo nathan Allen\, Joe Jesson\, Jonathan Allen\n\nRoom: 201\, Bldg: Roscoe Wes t\, 2000 Pennington Rd\, Ewing\, New Jersey\, United States\, 08628 LOCATION:Room: 201\, Bldg: Roscoe West\, 2000 Pennington Rd\, Ewing\, New J ersey\, United States\, 08628 ORGANIZER:Jejesson4@gmail.com SEQUENCE:6 SUMMARY:Restoration of Alan Turing's Preferred Interception Receiver - AR-8 8 URL;VALUE=URI:https://events.vtools.ieee.org/m/47403 X-ALT-DESC:Description: <br /><p align="justify">Come out to hear Joe Jesso n and Jonathan Allen speak about the RCA AR-88\, a receiver that was vital in capturing German messages during WWII.
