Thanks Franco! It remains to find out to what frequency to tune the input circuit L1 and C1, if I understood you correctly, then it should be approximately in the region of 80-100 MHz
In the L1 / C10 resonant circuit, by varying the capacitance of the capacitor, we see the amplitude of the signal, at the output of the sensor stage, increase when a harmonic of 20Mhz is reached, and then decrease moving away from it.
