Regenerative Receiver | Regen Radio| Electronics Notes The regen radio was one of the many inventions in radio technology that was made by Edwin Armstrong. He invented and patented the regenerative circuit while he was at college, in 1914. Although the invention of the regenerative receiver is generally credited to Armstrong, others contested this. Regenerative circuit A regenerative circuit is an amplifier circuit that employs positive feedback (also known as regeneration or reaction). Some of the output of the amplifying device is applied back to its input so as to add to the input signal, increasing the amplification. Super Regenerative Receiver | Regen Radio | Electronics Notes The super regenerative receiver is based on the simpler regenerative radio. It uses a second lower frequency oscillation within the regeneration loop that interrupts or quenches the main RF oscillation. The second or quench oscillation typically operates at frequencies above the audio range, e.g. 25 kHz to 100 kHz. Build the Retro Regen Radio | Nuts & Volts Magazine Schematic for the retro regen radio. The radio frequency (RF) signal from the antenna (binding post J4) is applied to winding L1 of the spider web wound coil. Winding L1 inductively couples the RF signal to a second winding L2 that — along with variable capacitor C1 — forms a resonant circuit covering the AM broadcast band (550 to 1600 kHz). One Tube Regenerative Radio Circuit Aaron Cake A regenerative radio works by feeding back a small amount of amplified output of the detector back into the input. Thus it achieves sensitivity far beyond what only a detector could alone. This simple regen radio uses a single tube as it's detector and amplifier; the "Audion".

A 12AT7 should also work quite well in this circuit. Any dual, low, or medium mu, triode will work just fine, provided it can be made to work at fairly low voltages. High Performance Regenerative Receiver arrl.org circuit's stability for CW and SSB reception. C7 is the throttle capacitor REGEN ADJUST control. As C7's capacitance is increased, more RF energy is coupled from Q2's drain to ground (and there fore the ground end of 1.2); this even tually initiates an RF oscillation. RF choke 1.3 isolates Q2's RF feedback from the detected audio, allowing just A Simple Regen Radio for Beginners arrl.org metal panel. The radio is easier to operate if you mount the TUN ING capacitor and the regeneration (REGEN) control on opposite sides of the front panel. The VOLUME and REGEN controls are best mounted near the bottom of the front panel to keep their connect ing wires to the PC board as short as possible. You can use the Collectible Tube Radios (Pre 1930) for sale | eBay 1923 Precision Crosley type ACE 3B Three Tube Regen Radio in VG Cond.
