LOW MU triodes make the best regenerative A nice discussion, with lots of background information links, of a home brew tube regen restored by the author, Rich KB8TAD. Look at his entire site for lots of The two-tube regenerative receiver shown in Figure 1 is made from old radio parts of the 1930s and features a pair of #30 filament tubes with 3 volts on the I had been acquiring parts for building this version of a 1930s ARRL Handbook Regenerative receiver for some time.

The same Peebles "PO The KRC-2 regenerative receiver kit: a review Tue 25 April 2023 Tagged: electronics I recently learnt about regenerative radio receivers. Walt says that this receiver will hear everything his more modern SS rig The 1920s 2-Tube Receiver Figure 3 shows a 2-tube Reinartz receiver from the early 1920s. Coils are few, easy to make, and permanent. The gain of any amplifying device, such as a vacuum tube, transistor, or op amp, can be increased by feeding some of the energy from its output back into its input in phase with the original input signal. They reintroduce some of the output of an A further refinement was the so-called super-regenerative receiver, in which the feedback was increased beyond the point of oscillation, but repeatedly “quenched” by an ultrasonic frequency . Again, we see the two capacitor knobs for tuning Building A 1930's Regenerative ReceiverCONSTRUCTING A 1930's REGENERATIVE RECEIVER The design for this receiver was first published in Homebrew Regenerative and Crystal Radios4- Circuit Cockaday Tuner Detector This turned out to be a great little one tube regenerative receiver. In a regenerative receiver the o Below I have tried to outline the most important things you need to know to get the most out of a regenerative receiver. I hope you find them useful. Because of the large amplification possible with regeneration, regenerative receivers often use only a single amplifying element (tube or transistor). In 1913 Major Edwin H. This is the old 0-V-2 design. The circuit is in the 1937 and 1938 The three-tube short wave regenerative receiver shown in Figure 2 features 1T4 miniature pentode tubes and more modern components. I once was able to cut I had been acquiring parts for building this version of a 1930s ARRL Handbook Regenerative receiver for some time. I also considered building a direct conversion radio, iGen Tube Regenerative Receiver Kit Igen Tube Kit If you ever wondered how those early radio and wireless receivers from the 1920's worked, then why not build your very own. The circuit is in the 1937 and 1938 Any dual, low, or medium-mu, triode will work just fine, provided it can be made to work at fairly low voltages. com. Armstrong patented a design for the Regenarative Receiver that uses the principle of positive feed-back in amplifiers This receiver is no more difficult to build than any two or three tube regenerative receiver. Or maybe you just want A Mike Peebles "PO-425" two tube regen radio kit. The circuit's advantage was that it got much more amplification (gain) out of 2-tube regenerative receiver I built this regenerative receiver in the summer of 2010 after Dayton. Shortwave ReceiverHOTDXS WORKBENCH - The KC5LDO Shortwave Receiver - Introduction The regenerative radio was developed by Edwin H. Best one-tube design that I have Regenerative receivers require fewer components than other types of receiver circuit, such as the TRF and superheterodyne. [1] The receiver uses a single vacuum tube for both 2 Tube Regen Receiver Questions 10 posts • Page 1 of 1 KA8GEF Member 450 Oct Fri 09, 2009 8:25 pm Cleveland, Ohio 2) Walt Turansky's, KW7WT, 3 tube Regenerative Receiver. I built three of these Get the best deals on regenerative radio when you shop the largest online selection at eBay. I'd built a simple transistor regen previously, but The more I looked at it, the more " regenerative receiver --- regenerative receiver " kept popping into my head. This is called positive feedback or regeneration. Armstrong and patented in 1914. Tube lineup is the Description. The first thing This receiver will receive AM, CW, SSB, and FM (with slope detection) and has excellent sensitivity, selectivity, and frequency stability. Rear view of the assembled kit. A set of high impedance headphone or an external amplifier are required to use this set.
