Suggested by a 1990 book for amateurs, this circuit makes use of an integrated component that is not common today. It converts signals from one band to signals in a 10.7 MHz band below.
This circuit was found in documentation from the 70s. We can try current JFET transistors....
The selected circuit generates short duration pulses at a frequency determined by R1 and C1. The...
This electronic ignition circuit was found in Motorola's Linear Databook of 1990. The components are not...
