This AM receiver circuit is based ob the IC ZN415 introduced by Ferranti. This IC is an improved version of the early ZN414. It is a complete AM radio receiver and does not need IF transformers and ...
The circuit exemplifies the use of ZN414 IC to produce a handy AM radio receiver. ZN414 IC– a composition of transistor tuned radio frequency (TRF) circuit packaged in a 3-pin TO-92 plastic package ...
This amateur radio hack is not for the faint of heart! With only three transistors (and a drawer-full of passive parts), [Peter Parker, vk3ye] is able to use a broken-looking AM car radio to receive ...
