Lrl from Italy

As I understand it ..... you talked about a circuit with a quartz at 8 MHz, there in the circuit yes L1-C10. I asked you about the 20 MHz quartz circuit and there in the L1-C1 circuit. Thank you Franco, now I understand your explanation about harmonics.

The 20 Mhz lrl is a improvement of 8 Mhz lrl, C10 in the 8 Mhz sensor stage has been replaced with a variable capacitor.
