VHF Super-Regenerative Receiver I have started straight with the circuit out of the ARRL handbook, by Charles Kitchen N1TEV. I didn't have a 6v8 zener, or a few other part values, so I had to substitute a bit. Unlike Charles' original circuit I found an audio pre-amp was needed to get

REGENERATIVE HF RECEIVER. Hi all, whilst looking through my lab book I came across this little receiver circuit. It looks like "kid's stuff" but it can be used for the lower HF bands and gives quite an impressive account of itself if used with a decent antenna. It can also be built into a cigarette box which makes it almost perfect for portable use.

From a French journal, a simple one-tube receiver. Page also has schematics for 2,3 and 4 tube receivers: Regenerative: 7.0: 30: 89: Original Armstrong Regenerative Radio: Here it is, Armstrongs original circuit straight from the patent application: Regenerative: 7.0: 10: 90: Homebrew "Vario control" Regenerative Receiver: Put that variometer ...
English: Single vacuum tube Armstrong regenerative receiver circuit, invented in 1913 by American engineer Edwin Armstrong when he was a 22 year old college student. It was widely used until the 1930s when it was replaced by TRF and superheterodyne receivers.
Regenerative receiver circuits are still used in low-cost electronic equipment such as garage door openers. A receiver circuit that used regeneration in a more complicated way to achieve even higher amplification, the superregenerative receiver, was invented by Armstrong in 1922, but was not as widely used. May 31, 2017 · This is a super-regenerative receiver. It is always oscillating at a frequency tuned to match the center frequency of the transmitter. C7 feeds back RF from collector to emitter to create RF oscillation. The value of the capacitor must be carefully chosen to provide just enough feedback for a weak oscillation. It cannot be too large or too small in value or the circuit will not oscillate at ... This describes the circuit and build (including coil winding data) of a 2 valve Shortwave Receiver. The valves are DF91 and the set has out put for headphones or another amplifier. Build details are given as is test and use of the set.

Nov 01, 2013 · The receiver is composed of an LNA and a super-regenerative oscillator (SRO), both combined in a single stacked configuration for current reuse. The demodulation of received RF signal is performed via a novel digital circuit capable of detecting phase information embedded in the SRO output.
