This video shows the crystal filter adapter for the BC348 shown on the previous you tube video in operation . The operation of this adapter after all the work trying different circuits on the circuit board I finally hit on a setup that performs amazingly well. So here is a video showing it in operation .I let the BC348 warm up for half an hour before making the video . This video shows development techniqus I use and suggestions for construction of home built projects in electronics . 73 and good DX Bob
