2.4ghz vco design help

i want to make vco for 2.4ghz band, can anyone advice if the below circuit is ok? i want to transmit audio using frequency modulation at 2.4ghz

This kind of circuit may be very sensitive against antenna position because the tank circuit is loaded by antenna and imaginary part of antenna impedance impacts directly tank frequency.In additional to, feedback capacitance is not fixed and very variable with temperature and biasing conditions so oscillation frequency may be pretty dependent.
I don't recommend this circuit, it will be a trouble in practical application.You should consider more sophisticated circuits with bias stability,independent from external effects,stable,high output power and good phase noise.You may find many 2.4GHz VCO circuits with modulation feature on the internet.
