. Topics include control-flow and data-flow analysis optimization instruction. Regenerative Receiver for Beginners. Regenerative Receiver Design Blocks.
As an added plus the design virtually eliminates the negative aspects of regenerative receivers such as antenna radiation frequency pulling micro-phonics and hand capacitance effects. Look at the design process and progress. Varactor-tuned BJT-only receiver differential 2xPNP for regeneration.
Regenerative receivers have a long history in radio dating back to the first days of the vacuum tube. Single transistor or jfet can achieve. High Performance Regenerative Receiver Design.
Regenerative receiversin German literature also called Audion are a very clever way to build receivers with a very small number of active components. I also considered building a direct conversion radio but the fact is a regenerative receiver can easily be used as a direct conversion.

Read Free High Performance Regenerative Receiver Design Direct-conversion receiver - Wikipedia The more I looked at it the more regenerative receiver --- regenerative receiver kept popping into my head. Design notes are also provided allowing you to tailor the component values further. As with the previous circuit this design uses a bipolar RF stage a J FET detector and an IC audio stage.
Based on the sound recording Mike provides his receiver has plenty of gain and exhibits all the benefits of a crystal-controlled regen. An automatic transmission car the D-C receiver is very easy to operate while the manual transmission car the regen receiver needs good design and has several tricky controls to skillfully operate but is capable of far better performance. Its tuning range is limited however and Mike used an obsolete transistor so I was unable to duplicate it.
Most of this reputation is due to design short cuts that have been implemented over the years. Though they were once very popular among amateurs and professionals alike they are now thought of as mere play toys instead of legitimate receivers. High-performance JFET regen tickler coil with capacative regeneration control filtered audio.
Above is a 1944 design of a band-switching receiver with regeneration in both mixer and 1650 kHz IFdetector stages. The band-imaging regenerative-IF superhet receivers such as the Simple-X or the Jones Super-Gainer have remarkable performance for their simplicity. Here is a collection of design blocks for creating a regenerative receiver to your own specification.
