This circuit was obtained in an old European publication on FETs. The FET admits equivalent and the feed must have good filtration. Signal input cables and output cables must be shielded.
We found this circuit in a documentation for 1977 American radio amateurs. The LM336 integrated circuit...
The frequency of this oscillator depends on the coil and the 10 nF capacitor. The circuit is from...
This circuit can work with the previous one generating signals, that can be decoded by it. The...
