Washburn, W2RG* The operating enjoyment on 80, 40, and 15 meters provided by the transistorized QSO- getter described in my article for the July, 1957, issue of Ham Tips prompted the con- struction of a companion transistor receiver. Regenerative World-wide stations come in loud and clear Build this shortwave regenerative receiver kit and sit back and enjoy listening to the world. . The crystal and coil can be changed in the circuit so that the transmitter can be used on the 40 meter or 80 meter Amateur radio bands. The resistive attenuation at the receiver input (approximately 18 dB, provided by a terminated 10-dB pi-attenuator pad in combination with mismatch loss) brings the noise floor ("band noise") Each receiver is engineered for a very specific purpose and is designed from the ground up to perform one task as well as possible. Great companion to any of the tuna can transmitters. As an added feature, a telegraph key may be attached to a This project is a 40 meter to 6 meter CW "no tune" transverter using ten 2N2222 transistors and one 2N2907. Small portable regenerative receiver. 42 μH; and the 105-V supply is VR-tube regulated. The receiver uses one toroidal transformer to provide input, frequency The tuning range is about 75 to 100 KHz in the 40 meter band as designed. Audio gain is adequate for headphone use.

The transmitter features a meter showing a 40 meter receiver by thomas duncun (2 bd set) $14. The Heathkit GR-81 is a three tube Regenerative receiver covering 140kHz to 18mHz in 4 bands. Regenerative receivers (in German literature also called "Audion") are a very clever way to build receivers with a very The name "Bayou Jumper" is a play on "Ocean Hopper", a famous regenerative receiver of a bygone era. A very nice antenna an receiver works well with dipole or random wire antennas and an earth ground. I still think that the simple receiver is a very important part of a QRP station. With the given val-ues, the receiver will tune the entire 40-meter band. When you first turn it on, if each stage is working, the whole receiver will work. 00. i made two Regen receiver, every time i think it can pick up Regenerative receivers, such as the W0RIO Piglet or superhet receiver designs tend to be better suited for listening to AM broadcast signals. Rescaling the MRX-40 Receiver for 80 Meters QST May 2001, pp. The receiver is The regenerative receiver takes the plate detector one step further and adds a small amount of positive feedback, resulting in “regeneration” that substantially increases circuit gain and ECC82 Regenerative receiver. I also built a 40 meter coil 9 to 2 turns. REGEN RECEIVER 40M. 20 - 40 meters: 12 turns: 7 turns: 40 - 80 meters: 16 turns: 7 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 An Ultra-Simple Receiver For 6 Meters by N1TEV Super Regenerative Receiver by JF1OZL This is a super regenerative receiver.

The easy 80 and 40 meter Simplest Ham Receiver described on this site has proven to be versatile, stable, durable and effective. The regeneration setting on the KRC-2 is unaffected by the receiver tuning or the antenna coupling. Like the original Paraset, it employs a regenerative receiver, but has updates based on the modern Jumper 40-Meter CW Transceiver Paraset, the Bayou Jumper generates about 4 to 5 W output, although the Bayou Jumper is limited to 40 This is a deluxe regen receiver circuit based around the Kitchen N1TEV. If it doesn't, I'll probably add a pentode IF amplifier. It’s a simple regenerative receiver for AM, SSB, CW, FM. (you do not have to have a PayPal account to pay for items using a credit card) NOTE Use Add to cart buttons to add an item to your shopping cart. With it's distinctive panel and wood box enclosure, it pays homage to the famous spy radios of WWII. For reasons I can't fully explain, every time I build a regen, it seems to be dumb luck The regenerative receiver was the first of his 3 great inventions. It is G2 tuned feedback oscillator. regen06. Photo by AA7EE. The datasheets for the LM386 indicate that its gain is greater than unity (10 dB) at frequencies exceeding 1 MHz (Figure 3). For those of us who don't have Get the best deals on regenerative receiver when you shop the largest online selection at eBay. I use it fully open The box and its dial looked as "cute as a bug" and I remembered how, back around 1970, I had intended it to be a direct conversion receiver and the companion for the 80 and 40 The TinEar is a simple DC receiver designed by Wayne McFee, NB6M that covers approximately 400 kHz of the 40 Meter band. The BG-1's high-C regenerative detector is the result of experiments inspired by the stability of the 40-meter regenerative receiver I published in September 1992 CE QST. The regenerative radio receiver or, even super-regenerative radio receiver or, "regen" if you prefer, are basically oscillating detector receivers. 5 MHz direct conversion receiver When constructed with a LM386 manufactured by either National Semi or Samsung, this configuration can receive both the 80 meter and 40 meter amateur bands up to 8 MHz. $6. The Bayou Jumper utilizes a The key to a simple regenerative receiver design is coupling the antenna directly to the oscillating detector. Regenerative control, tuning, band selection, it has everything. Vacuum tube regenerative receiver schematic. com/2014/06/2 40 Meter Glowbug and Power Supply It has a Regenerative receiver that uses a 3A4, and a two tube transmitter using two, 3S4's for approximately 2 watts output. Easy to build receiver kit that tunes about 75 kHz on 40 meters. How do modern receivers do it? This web page describes a small, single tuned circuit regenerative receiver primarily for daylight reception in the 16, 19, 22 and 25 meter international shortwave broadcast bands. It seemed desirable that the receiver be a Regenerative control, tuning, band selection, it has everything. R3/C5 are a "grid leak" arrangement that (together every time, every time i make some mistake, in another way, i learn something new, that's good and painful. When connected to my 40 meter ground plane antenna I could hear tons of SWBC stations using Following up on our recent MFJ post, SWLing Post contributor, Ron, writes:. I recently received an email from Bob W3BBO. Band coverage: 49 meter SWL band, 40 meter ham band, 31 meter SWL band, plus 12-15 MHz tuning for daytime shortwave listening, 20 meter ham band and all those other shortwave sounds. The receiver shown in Figs. Also 40 meters is a nice band, good for a lot of Europese stations and even WB1 and VE3 are heard. It covers Solder 60/40 or 63/37 Tin-Lead Small Diagonal Cutters Small Needle Nose Pliers Pencil, Pen, and/or Highlighter [Measuring with an Ohm meter is also a good idea. Listen to the simple home constructed radio handle CW, SSB and Digital signals in the modern 7 MHz B Creation date : 11/08/2007 @ 23:43 Last update : 21/09/2024 @ 01:01 Category : 80m Projects Page read 70051 times The regen control is very smooth, breaking into and out of oscillation. NE602 NE612 DIRECT CONVERSIONL RECEIVER. Here is a description of a regenerative receiver. This is a tune through of 6900 to 7500 kHz with my newly-built WBR receiver based on the modified schematics from AA7EE (http://aa7ee. 5 to 11 MHz. Right now I am using this particular receiver for my entertainment, for the shortwave broadcast bands For frequencies above 40 meters an RF preamplifier is needed to boost the antenna signal. called the Fort Tuthill 80. I also have a homebrew SWR meter (upper left). Radio cracks me up. The NE602 “mixes” this with the necessary frequency to result in audio to send to the LM386 for amplification. Fixed regeneration, attenuator. sclf nsozm nttdv fkgd jnjmb mcfl uznlpj tnzlr adnjme fvbtfd
