Figure 6 Create LM386 shortwave regenerative receivers using high gain and RF envelope detector modes. Building a tank circuit from 8 turns on a 3-inch ferrite rod and both gangs of a standard MW polyvaricon variable tuning capacitor gives circuit 6 a tuning range of approximately 3.5 to 10.5 MHz, which covers both the 80 and 40 meter amateur bands. There …
