The use of a regenerative detector provides very high sensitivity, allowing the radio to receive even weak signals. Additionally, the differential pair design and the use of a tuned tank circuit provide high selectivity, allowing the radio to reject unwanted signals from other stations. The circuit is relatively simple and can be built with readily available components.

15M regenerative receiver. Performance is nice -  good sensitivity, adequate stability and easy to fabricate.The same circuit can used for 20M, 40M or 80M bands by suitably changing the values of tuning components.

This is my version of NA5N's "Pipsqueak" regen. My first homebrewed radio and a lot of fun to build. And it works!Here's NA5N's original article on the build...

K8TND VHF Regenerative Receiver for AM Aircraft Band   This product has been discontinued. Ever wonder what those airplanes in the sky are really saying to the control tower and to each other? Well now you can find out with the compact K8TND VHF Receiver for the 108-136MHz AM VHF band. Listen to the sample […]

NOTE - Many thanks to Aaron N9SKN and Cliff WA9YXG, who pointed out errors in the schematics. They have been corrected. N9SKN, and several others, have built working Sprouties from the schematics in this post so rest assured that if you follow them, you can too. If you're thinking about building this great little general…

EDIT (July 26th 2014) - If you're thinking of building the WBR, I strongly suggest you check out my most recent build here, which incorporates a mod suggested by LA3PNA, and a different configuration for the AF amp that I think provides nicer sounding audio. The full schematic is published there also. A few weeks ago when…

Before I go into the details, let me say that I've built about 1/2 dozen one and two tube Regens over the years (and several superhets) and this one is by far the most selective, most stable, and easiest to use Regen. The 12AL8 and 5687WB or 7044 tube combinations work well, as does the 12AL8 and 5814WA (12AU7) combination with the plate voltage reduced to around 8V. Copying CW and SSB, as well as AM SW stations is easy. I have not had a chance to try more of the MANY other dual triodes like the 12AT7, 12BH7A and they may all work as well. I'll expand this write-up as other items come to mind. There will be a low voltage (24V ? 48V ?) CW transmitter to follow.

EDIT - If you're thinking of building the Desert Ratt 2, although the pictures in this post are numerous and quite large, I do recommend reading all the text too, as I have included what I thought were relevant details on the construction as part of my narrative. Also make sure to read the comments and…

Continuing an exploration of "Noisy Regen" radio receiver circuits using only basic electronic components.

The Noisy Regen circuit as described by Alan Yates is a simple and easy to construct regenerative radio receiver. In addition it is a very repeatable circuit in contrast to other regen designs which are problematic to replicate. (See: www.vk2zay.net/article/128) In the circuit the differential pair

This is a pocket sized receiver I built in 1994. The idea was to make a simple but useable receiver running off 3V. My previous 6 transistor receiver was more bulky, requiring 12V. This meant 10 x AA cells. I designed and made a PCB, and constructed a small aluminium case to keep the receiver as comact as possible. There is nothing unusual with this design. The detector uses a simple Colpitts oscillator and is of a type commonly used in other super regen receivers. Of course it is self quenched. Sensitivity with this type of detector is relatively low, but it's simple and easy to get working. As always, I provided a regeneration control to set the optimum operating point; ie. max sensitivity and minimum SCA/stereo subcarrier beat.

I got a tip the other day that there is an interesting circuit over at the RadioBoards Forum where an LM386 IC is used as a regen receiver for the medium wave band. It is the user 'Selenium' who has come up with that circuit. I think it is quite an ama...

Since I began posting about regens, it has been gratifying to hear from fellow regen builders, and quite interesting and inspiring to communicate with other hams who are also taken by their charms. The Sproutie has proved to be a great little receiver and it's a pretty straightforward circuit, but it's not exactly a minimalist…

Als mein Regenmantel von Didriksons ankam, erwartete ich - man kann es kaum glauben - sehnsüchtig den Regen. Aber nichts da.
