Simple HF Regenerative Receiver

Figure 1 shows the schematic of the receiver. Points 1 and 2 are heater. Point 3 is ground (minus) and point 4 is plus of the plate voltage. The receiver works fine from 100- 250- V. Table 1 shows data for capacitors and resistors. Inductors of the receiver are coiled on the base from old tubes. Figure 2 shows design of the coil. Distance between inductor L1 and L2 shown approximately. The distance may vary when it would be tuned on to smooth regeneration of the receiver. Table 2 shows data for the inductor. Analog the Russian Pentode is: to firs tube is: 6J7, Z63, 6W7, EF36, EF37A. Analog for Russian twin Triode is: 6N7GT. Also may be used: B65, ECC32, 6CC10, 6SN7GT.

Receiver built on aluminum L- shape profile. Figure 3 shows view of the receiver. Tubes and Plug- In Inductor placed at the upper side of the receiver. Figure 4 shows inside view on to the design. All connections made by stranded wire in diameter of 1.0- mm (18- AWG).
