This circuit uses an 18 MHz crystal to generate 36 MHz signals. We found it in an 80's documentation. The circuit has an input for frequency modulation.
This circuit was obtained from a Poptronics in June 2001. The magazine no longer exists, but the...
We find this circuit in a 1980s documentation. The circuit uses uncommon components today which can...
This circuit has a very high input impedance and a very low output impedance. We found it on a...
