The diagram is circuit which consists of VD1, VD2 two variable capacitance diodes, its oscillation frequency is concerned with R1、VD1-R2、VD2, in order to adjust frequency range, the capacitances and resistances of two Bridge road branchs must change the same value of number at the same time. So need to use coaxial connecting two potentiometer or duplex capacitors.
