The FET can be a BF245, and the other transistors can be the BC548 and BC558 in this simple AM receiver. Adjust R4 for the best sound. The coil has 20 + 60 turns of wire 28 in a ferrite rod.
The integrated circuit used in this 90's circuit is not common today, but the configuration can be...
We found this circuit in a 1976 publication for radio amateurs. It was originally intended for use in...
We found this high input impedance, low output impedance amplification stage in the October 1993...
