I Think that with Franco Xtal LRL , Lucky frequency can be is with 9.736,305 Mhz .
According to my experience my lrl works with these frequencies: 2.8Mhz (CD4046 version) - 3 - 4 - 6 - 8 - 10Mhz. It is possible that with high frequencies, for example 9 or 10MHz, the sensor stage amplifies more, since TR3 and TR4 are in practice a high pass active filter, through the capacitors placed between emitter and ground.
