A SHORT WAVE REGENERATIVE RECEIVER PROJECT Short wave regenerative receiver set up. Be sure to use a good ground connection with this receiver. This increases sensitivity and also makes the receiver more stable and easier to tune and operate. For a better (less noisy) ground, connect the receiver's ground wire to a cold water pipe or radiator. How I built a shortwave Armstrong FET regenerative receiver I also considered building a direct conversion radio, but the fact is, a regenerative receiver can easily be used as a direct conversion detector simply by turning up the regeneration. A regenerative detector is much more robust than any dual gate FET mixer, it is very sensitive to weak signals and it will demodulate AM in addition to single side band and Morse code. K8TND Regenerative Receiver QRPGuys The receiver is 4.50″ wide x 3.00″ deep x 2.00″ high. On a difficulty scale of 1 to 5, 5 being the most difficult, this is rated at 2 to 3, depending on your experience. Visit s: m.short wave.info for a description of the stations that are available worldwide. Regen Shortwave Receiver A short article describing a simple homebrew regen receiver. Shortwave radio is what got me interested in this radio stuff in the first place.Ever since I was a kid huddled in front of an old console radio my grandmother gave me, I've been fascinated with the notion of listening broadcasts originating half way around the world. A Regenerative Receiver for the Short Wave Bands This is a new Regenerative receiver for the Short Wave bands. It uses readily available parts and covers 3Mhz to around 12Mhz. The full design notes are available in two PDF files, the notes below are an extract for this web page. 3 Transistor Short Wave Radio The 3 Transistor Short Wave Radio illustrated in this article is a regenerative receiver design. The Superheterodyne receiver uses many of the same components as the TRF and Regenerative receivers but adds special oscillator and amplifier circuits that make tuning into the desired station very easy. The KRC 2 shortwave regenerative receiver kit | The SWLing ... Tony Westbrook recently contacted me about a regenerative receiver kit he has designed and produced in the UK. It’s called the KRC 2. Here’s the product description: 1 – 30 MHz with band spread tuning. Regeneration with a difference. The regeneration setting on the KRC 2 is unaffected by the receiver tuning or the antenna coupling. Some Regenerative Receivers W7EKB 5) RCA designed "Battery Operated Short Wave Receiver". This is a TRF receiver which uses battery tubes which require 1.4 volts for their filaments. This design is very similar to RCA's A.C. operated, "Regenerative Shortwave Receiver". Shortwave Radio Receiver Plans & Kit MTM Scientific The coil is tapped 4 turns from the bottom to provide a regenerative feedback signal. The first transistor comprises the RF amplification stage, and signal regeneration is controlled by adjusting the variable potentiometer. (The trick in using the regeneration is to adjust the gain just short of causing feedback oscillation.) High Performance Regenerative Receiver of this receiver, it is only necessary to wind another coil. Operation can be extended all the way down to the long wave frequencies and as high as the 10 meter band. When winding coils, corresponding windings should occupy about the same length (expand or compress turns as necessary) and position (along the form) on all coils. Regenerative Receiver for Beginners short wave bands from 1.6 to 25 MHz, which includes the 80, 40, 30, 20, 17, 15 and 12 m ham bands. It offers good sensitivity and selectivity and is very portable, powered by two 9 V batteries. It has provision for operating on an ...

Ham & Amateur Radio Receivers for sale | eBay When you want to communicate through amateur and ham radio systems, having the right receiver makes a big difference. On eBay, there are many different manufacturers of ham and amateur radio receivers. Choose from new or used communications receivers at a variety of price points when shopping on eBay. Knight Ocean Hopper regenerative receiver Knight Ocean Hopper receiver. This Knight Ocean Hopper receiver from Allied Radio is a three tube regenerative set covering the broadcast band. Five plug in coils sold separately increase the coverage from 165 KHz to 35 MHz. Tubes are 35W4 as rectifier, 50C5 for audio output and a 12AT6 triode as the regenerative RF detector. Building a Doerle Two Tube Shortwave Receiver Radio Boat ... Doerle "sets" were a popular home built regenerative shortwave receiver of the 1930s. Designed by amateur radio enthusiast Walter C. Doerle of Oakland, California. Doerle's regenerative radio designs were published in many amateur radio magazines in the 1930s. The AA8V Twinplex Regenerative Receiver L1 and L2 Coil ... The original short wave coils for the receiver were wound on coil forms that have octal bases, a diameter of 1 1 4", and have ribs on them that keep the windings spaced about 25 turns per inch. The last time I checked, these forms were no longer commercially available. Short Wave Superregenerative Receiver | Electronic ... Short Wave Super regenerative Receiver Circuit diagram. Super regenerative receivers are characterized by their high sensitivity. The purpose of this experiment is to deter mine whether they are also suitable for short wave radio. Super regenerative receivers are relatively easy to build. You start by building a RF oscillator for the desired ... Multi Band Regenerative Receiver (Vacuum Tube) Tunes in the AM band from 670 KHZ to 1.7 MHZ and the short wave bands from 6.7 MHZ to 17 MHZ. This is a two tube regen or regenerative receiver: one 1T4 detector and one 3V4 audio amplifier. All of this is accomplished with two plug in RF coils. What's the best regenerative receiver you've ever built ... Back in the day, Radio had so called P Kits. One of these was a regen receiver (Science Fair brand Three Transistor Shortwave Radio (Catalog #28 110)) Great fun to listen to n the summer night wire in the air and ground hooked to the outdoor faucet. Simple High Performance Shortwave Regenerative Receiver The very last schematic is a shortwave regenerative receiver using only a single LM386 audio amplifier. On a 9V supply it will oscillate up to about 8 MHz. Volume is more than adequate for commercial shortwave broadcast stations, but sensitive earphones or an additional transistor audio stage would be best for receiving SSB on 80 and 40 meters. Regenerative Receivers Regenerative Receivers. Regenerative receivers provide a surprising level of performance with only a handful of components. They excel at receiving amplitude modulated signals from below the AM broadcast band up to the higher short wave bands above which the superregenerative detector becomes the better choice. 23 Best What's Regenerative Radio images | Ham radio ...
