This simple regenerative receiver works well using a small wire antenna in length 2... 3 meters. The receiver is easy to tune up and does not contain hard- to find parts. At the design two amateurs bands are included- 40 and 20- meters. However it is possible to retune the receiver to any other bands. Figure 1 shows schematic of the receiver.

Aperiodic RF- Amplifier made on VT1. VT2 and VT3 consist the heart of the receiver- the regenerative detector. First stage of the Audio Amplifier made on VT4. VT1, VT2, VT3 and VT4 would be any small power HF transistors. Gain should be not less the 100. Working frequency should be not less 100- MHz (off course, above the VT4). DA1 is voltage stabilizer that provides 5- V for regenerative stage. Final audio stage made on DD1. CD4001A is the full analog of the Russian chip.
