Single AA battery one tube DF97 Fm super regenerative radio with audio amp



Published
I connect LM386 set 100 gain for make this video , is difficult to connect to audio amplifier because the earphone jack wire also act as antenna and i only able to receive one FM channel. When connect to audio amplifier the load changing because the Earphone also a part of Plate load.. so it cause some whistling when tuning across the frequency..
