Devices Selection The machine circuit is shown in the picture and it is a superregenerative receiver circuit.Because most channel frequencies work between 88MHz~108MHz and take Shanghai literature and art channel (the middle frequency is 96.8MHz)as example.L2 uses Φ2mm silver-coated copper wire.On the diameter Φ15mm mould,it can be roped into 5 circles hollow type whose coil distance is 2mm. The distances between two circles is about 2mm-3mm.The radio frequency choke uses Φ0.32mm lacquered wire.The diameter 10mm paper tube is raped into 150 circles which is divided into three sections hives and the distance is 2mm.
