Two possible regenerative receiver circuits built from the circuit blocks are given in figures 6 and 7. Figure 8 is a useful audio filter circuit for regenerative receivers. It allows you to reduce 5KHz and 10KHz heterodyne tones from strong adjacent carriers and gives a treble boost that is useful with high selectivity circuits. Mar 07, 2002 · VHF Super-Regenerative Receiver. I have started straight with the circuit out of the ARRL handbook, by Charles Kitchen N1TEV. I didn't have a 6v8 zener, or a few other part values, so I had to substitute a bit. Unlike Charles' original circuit I found an audio pre-amp was needed to get sufficient AF gain so the 386 could.
Jeff shared with me several YouTube links that have receivers like this that many hams and experimenters have built. This particular receiver design comes from Charles Kitchin N1TEV. His design is a modification of a classic design that dates back to the 1920's. The main modification is the use of the LM386 audio amplifier IC to give it a. !

stability of the receiver though, the fine tune control is a must to be able to keep up with the thermal drift from your breath. Here is a spectrogram of the receiver in super-regenerative oscillation. The quenching rate is about 120kHz, the waveform looks rather sawtooth like, but has smooth edges. The spectrum analyser's IF bandwidth is about.
This simple receiver uses three Russian rod pentodes, a marvellous device from the cold war era and in plentiful supply to this day ( Ebay ). AB2FG's regen radio for 80 meters based on design by Charles Kitchin, N1TEV, in Nov/Dec 1998 QEX. ARRL Regen for beginner, ARRL Regen Receiver , N1TEV, suggest this receiver: you need a Regen built experiment before you move on. it's worthy to do. below pictures show the final Receiver built via Manhattan style PCB with a panel.

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 capacitor..

This receiver took advantage of the drop in component prices toward the end of the 1930s, and the ensueing post WW2 surplus parts flood. In fact, by 1948, why, for the price of a meal at a diner, you could purchase most of the components for this receiver, and the tube.
"A regenerative radio receiver is unsurpassed in comparable simplicity, weak signal reception, inherent noise-limiting and agc action and, freedom from overloading and spurious responses. The regenerative radio receiver or, even super-regenerative radio receiver or, "regen" if you prefer, are basically oscillating detector receivers. Armstrong regenerative detector cir- cuit. This receiver uses a 2N4416 JFET (orJ31()), which provides a more sensitive detector than an MPF102. Secondary winding 12 and capaci- tors C3 and C4 select the received sig- nal while tickler winding 1.3 provides regenerative feedback. R3/C5 are a "grid leak" arrangement that (together.

Building the N1TEV Regenerative Shortwave Receiver. This project is designed to be built using the FAR Circuits printed circuit board (the name of the PC board is the same as this project's title). The use of this board is HIGHLY recommended as it greatly reduces the time spent soldering the circuit and avoids the many wiring errors that always.
