• Although the familiar regenerative circuit looks like the image on the right, Armstrong’s original designs were considerably different. His 1913 patent application had six different drawings, none of which had a plate circuit coil (tickler) inductively-coupled to the grid coil, and interestingly, none had a D.C. path to ground from the grid.
• Circuit Description. See notes regarding the 15uH chokes. The heart of the receiver is the right hand side triode. This is the super-regen detector. By means of the cathode choke, and the internal grid and cathode capacitances, this triode oscillates at whatever frequency the grid circuit is tuned to.
• Armstrong's receiver was compared to the American Marconi Type 101, a sophisticated crystals set, and probably one of the best receivers then in use. The IP-501 was the U.S. Navy's first receiver with the vacuum tube inside the cabinet. This regenerative design was the work of Alan Hazeltine. We'll use this as a standin for the 101.

• Regenerative sets can cause interference to other local receivers when the set oscillates. Since the signal can't travel backwards through the tube the signal won't radiate from the antenna. The second stage is the regenerative detector. The coupling between the first and second stage is done by inductive coupling.
• May 31, 2017 · This is a super-regenerative receiver. It is always oscillating at a frequency tuned to match the center frequency of the transmitter. C7 feeds back RF from collector to emitter to create RF oscillation. The value of the capacitor must be carefully chosen to provide just enough feedback for a weak oscillation. It cannot be too large or too small in value or the circuit will not oscillate at ...

• Mar 05, 2020 · The Scout Regen receives CW, SSB and AM signals from 3.5 to over 10 MHz. in two bands . Includes a painted and silk screened chassis, circuit board and all parts. Headphone level audio output with diode audio limiters to protect the listener. Powered by on board 9V battery or external supply. Current consumption of approximately 8mA. The receiver is designed and simulated in 130 nm CMOS process and the whole circuit's power consumption is 119µW for the input of −80dBm at the rate of 6 Mbps with Energy Per Bit of 19.8 pj/b. LNA... The regenerative circuit remained a favorite design for home-constructed shortwave broadcast radios and amateur receivers throughout the 1930s. From the 1940s on, regenerative radios (mostly tube based) have been offered in commercial kits and have been the subject of numerous magazine construction articles.Regenerative receiver CW reception (autodyne mode). For the reception of CW radiotelegraphy ( Morse code ), the feedback is increased just to... SSB reception. For the reception of single-sideband (SSB) signals, the circuit is also adjusted to oscillate as in CW... Advantages and disadvantages. ... Circuit Description . The receiver, dubbed 'The Moorabbin', is a two transistor regenerative receiver of conventional design. Most parts are mounted on a printed circuit board that you get to make yourself. The regenerative detector uses a field effect transistor (FET). Like with the better valve designs, feedback is controlled by a variable ...

Apr 06, 2009 · It is amazing that in the early 1920s, Edwin Armstrong devised a super-regenerative receiver circuit using few components that trade log of gain for bandwidth, contrary to the conventional wisdom that gain and bandwidth should trade off more or less directly.

• regenerative circuit while he was a junior in college, in 1914. [6] He patented the super-regenerative circuit in 1922, and the superheterodyne receiver in 1918. Lee De Forest filed a patent in 1916 that became the cause of a contentious lawsuit with the prolific inventor Armstrong, whose patent for the regenerative circuit had been issued in 1914.
